An ESX Administrator plans to install additional supported components on the ESX Server that
would increase the memory requirements for the Service Console. Which ESX Server partition
would also need to be increased during installation as a result?
A. /
B. vmfs3
C. swap
D. /boot

Answer: C
Explanation:
Mastering VMware vSphere 4, page 25.
'As a general rule, swap files are created with a size equal to at least two times the memory
allocated to the operating system. The installation process allocates a default amount of 300MB of
memory for the Service Console; therefore, the default swap partition size would be 600MB. '
'It might be necessary to increase the amount of memory granted to the Service Console. ...If
additional third party applications are needed to run in the Service Console...then more memory
may be needed...'

QUESTION NO: 5
When installing ESX 4.0, where is the Service Console file system located?
A. In a virtual disk on a local VMFS datastore
B. In a virtual disk on a local or shared VMFS datastore
C. On a local physical disk or on a mapped SAN LUN
D. On a local physical disk

Answer: A
Explanation:
The reason for this is the fact that the service console is a VMDK. This VMDK is stored on the
local VMFS volume by default in the following location: esxconsole-/esxconsole.vmdk.
Everyone at this point should be aware that the Service Console is now located in a vmdk on a
VMFS partition. The Service Console vmdk must be stored on a vmfs datastore and the datastore
must either be local storage or SAN storage that is only presented to the one host

QUESTION NO: 6

Once vCenter 4.x has been installed, a License Server is required in which of the following
instances?
A. A License Server is always required
B. To support ESXi 4.x Hosts
C. To support ESX 3.5 Hosts
D. A License Server is no longer required

Answer: C
Explanation:
vSphere uses a new centralized license reporting and management structure, which means that if
all ESX hosts are upgraded to version 4, no license server or host license file is needed. ESX 3.5
hosts still require access to a license server, which can be used by the vSphere Virtual Center by
configuring the License Server option under Administration—Server Settings.

A. performing a host compatibility check
B. upgrading standalone ESX/ESXi hosts
C. upgrading ESX hosts in DRS/HA clusters
D. keeping guest operating systems patched

Answer: A,B
Explanation:
vSphere Host Update Utility
This tool is for upgrading ESX 3.x/ESXi 3.5 standalone hosts to ESX 4.0/ESXi 4.0 and for patching
ESXi 4.0 standalone hosts. A standalone host is an ESX/ESXi host that is not managed in vCenter
Server.
When you select a host to be upgraded, the tool performs an automated host compatibility check
as a preupgrade step.

QUESTION NO: 16
After upgrading an ESX host to vSphere 4, which of the following three actions should be taken
(Choose Three)?
A. restore files to the service console
B. boot into Troubleshooting Mode for proper operation
C. configure licensing
D. verify virtual machine operation
E. connect the host to vCenter if managed

Answer: C,D,E
Explanation:
vSphere Upgrade Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0 vSphere Client 4.0, page 79.
After you upgrade an ESX/ESXi host, consider the following:
• View the upgrade logs.
• If vCenter Server manages the host, you must reconnect the host to vCenter Server by rightclicking
the host in the vCenter Server inventory and selecting Connect.
• When the upgrade is complete, ESX/ESXi is in evaluation mode. Evaluation mode lasts for 60
days. You must assign an upgraded license to your product within 60 days after the upgrade. Use
the License Portal and the vSphere Client to configure licensing.
There is no requirement to restore files to the service console after an upgrade
Troubleshooting mode is not a valid mode for a vSphere host
It makes sense to verify virtual machine operation after an upgrade has taken pace.

QUESTION NO: 17
Before you upgrade an ESX host?
A. back up /proc, /mnt, /tmp, custom scripts and all VMFS datastores
B. back up /home, /etc/init.d and /boot

command, see the vSphere Command-Line Interface Installation and Reference Guide.

QUESTION NO: 19
Before you upgrade an ESX/ESXi host (Choose Three)?
A. verify current hardware is supported per the vSphere Systems Compatibility Guide
B. compare the md5sum of the downloaded file to the value on the VMware download website
C. schedule a maintenance window for 32-bit hardware
D. run the vSphere 4 Pre-Upgrade Script from the command line
E. run the VMware CPU Identification Utility

Answer: A,B,E
Explanation:
Ensure that the hardware and/or virtual machine meets the minimum system requirements for
VMware vCenter 4.0
You can use vSphere Host Update Utility to upgrade ESX 3.x to ESX 4.0 and ESXi 3.5 hosts to
ESXi 4.0. You cannot use vSphere Host Update Utility to convert ESX hosts to ESXi hosts, or the
reverse. When you select a host to be upgraded, the tool performs an automated host
compatibility check as a preupgrade step. The check verifies that each host is compatible with
ESX 4.0/ESXi 4.0, including the required CPU, and has adequate boot and root partition space. In
addition to the automated preupgrade script, you can specify a postupgrade configuration script to
ease deployment.
Note the preupgrade script is automated and so does not need to be run explicitly.

In order to upgrade to vSphere 4, an ESX host must have a /boot partition of at least?
A. 150 MB
B. 200 MB
C. 100 MB
D. 50 MB

Answer: C
Explanation:
vSphere Upgrade Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0 vSphere Client 4.0 Page 73
Direct, in-place upgrade from ESX 2.5.5 to ESX 4.0 is not supported, even if you upgrade to ESX
3.x as an intermediary step. The default ESX 2.5.5 installation creates a /boot partition that is too
small to enable upgrades to ESX 4.0. As an exception, if you have a non-default ESX 2.5.5
installation on which at least 100MB of space is available on the /boot partition, you can upgrade
ESX 2.5.5 to ESX 3.x and then to ESX 4.0.

QUESTION NO: 26
Securing an ESX service console is important because?
A. Service Console actions can affect all VMs on an ESX host
B. Service Console permissions are applied to users when logging in to a host via vCenter
C. VMs run in the service console
D. VMs depend on the patch level of the service console

Answer: A
Explanation:
With VMware ESX being loaded on top of the server hardware, there are a few points of
immediate concern:
These two pieces are two very distinct parts of VMware ESX. VMware has periodically released
patches for both of these different components although you probably just thought of them as
"ESX patches".
Concerning #1, the VMKernel and its virtualization layer is extremely secure. The Guest machines
have hardware isolation in place and it seems impossible that a guest VM could somehow
compromise the security of the host virtualization layer.
As for #2, with the services console being based on Linux, it will be affected by most of the Red
Hat Linux vulnerabilities. Because the service console is a Linux OS with a direct link to the
VMKernel, I will focus on securing the service console

QUESTION NO: 27
ESX Service Console patches should be applied (Choose Two)?
A. as instructed by VMware authorized technical support personnel
B. when an issue is identified
C. as Red Hat makes patches available
D. as VMware makes patches available

Answer: A,D
Explanation:
After you register your ESX Server license, you will get email notifications of new patches. If you
haven't been notified about patches, you can check the ESX Patch update site to get the latest
patch info
Patches will be either for security reasons, critical bug fix issues, or general system bugs. Of
course, security and critical bug fix patches should be applies as soon as possible. Many of the
ESX Server patches are actually for the service console (based on Red Hat Enterprise Linux).
Although, don't try to apply Red Hat patches to the service console as you will find out that they
don't work

QUESTION NO: 28
ESX Service Console patches should be applied (Choose Two)?
A. in accordance with VMware Security Advisories
B. when notified on the VMware Security Blog
C. when advised by VMware authorized technical support personnel
D. in accordance with VMware and RedHat Security Advisories

B. can use a central directory service for password checking only
C. requires local accounts
D. controls vCenter authentication for vSphere Client users

Answer: B,C
Explanation:
Enabling Active Directory Authentication with ESX Server, page2.
A variety of authentication providers are available for use. ESX Server includes services that can
be used to meet your authentication needs but also supports the use of other authentication
providers. This is especially useful in cases where a collection of users has already been
established, as in organizations using Active Directory. To facilitate the use of such providers, ESX
Server includes an option in the esxcfg tool to configure the use of other authentication providers,
(A).
ESX Configuration Guide ESX 4.0 vCenter Server 4.0, page 165.
The default installation of ESX uses /etc/passwd authentication as Linux does, but you can
configure ESX to use another distributed authentication mechanism, (B).

QUESTION NO: 33

An administrator is installing an ESX Host to boot from a SAN LUN. Which of the following two
requirements are necessary when configuring the HBA in the ESX Host (Choose
Two)?
A. The HBA BIOS must be enabled
B. The HBA must be plugged into the lowest available PCI bus and slot number
C. The HBA BIOS must be disabled
D. The HBA must be plugged into the highest available PCI bus and slot number

Answer: A,B
Explanation:
VMware ESX Server SAN Configuration Guide, page 61.
ESX Server Configuration Requirements for Booting from SAN
· The HBA BIOS for your QLogic HBA Fibre Channel card must be enabled and correctly
configured to access the boot LUN.
· The booting logical unit number (LUN) must be visible from the lowest numbered HBA that
has any visible LUNs.
· The boot LUN must be visible from the lowest numbered storage processor (attached to that
HBA) that has any visible LUNs.
· The boot LUN must be the lowest numbered LUN attached to that storage processor (except
for gatekeeper LUNs which are sometimes assigned LUN0).
· You must remove all internal SCSI drives for all servers.
· HBA numbers can change automatically when you add and remove PCI adapters, or
manually when you edit the /etc/vmware/devnames.conf file. The HBA must be set to the lowest
PCI bus and slot number. This enables it to be detected very quickly since the drivers scan the
HBAs in ascending PCI bus and slot numbers, regardless of the associated virtual machine HBA
number.
· If you are running an IBM eServer BladeCenter and boot from SAN, you must disable IDE
drives on the blades.

QUESTION NO: 35
An administrator is installing an ESX Host to boot from a SAN LUN. The storage array is an
active/passive array. After configuring the boot LUN and installing ESX, the system does not boot
properly.Which of the following could cause this issue?
A. The Storage Processor port specified in the BIOS configuration of the HBA is passive
B. The LUN specified in the BIOS configuration of the HBA is active
C. The Storage Processor port specified in the BIOS configuration of the HBA is active
D. The LUN specified in the BIOS configuration of the HBA is passive

Answer: A
Explanation:
VMware ESX Server SAN Configuration Guide, page 60.
When you boot from an active-passive storage array, the storage processor whose world wide
name (WWN) is specified in the BIOS configuration of the HBA must be active. If the storage
processor is passive, the QLogic adapter cannot support the boot process.

QUESTION NO: 36

Explanation:
VMware ESX 3.0.0 SAN Booting Disaster Recovery - Boot images stored on disk arrays can be
easily replicated to remote sites where standby servers of the same HW type can boot quickly,
minimizing the negative effect a disaster can have to the business iSCSI SAN Configuration Guide
ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 52. Boot from a SAN:
1. If you do not want to handle maintenance of local storage.
2. When you need easy cloning of service consoles.
3. In diskless hardware configurations, such as on some blade systems.

QUESTION NO: 37
What is the proper LUN Masking configuration for LUNs presented to an ESX Host when using the
Boot from SAN option?
A. The Boot LUN should be masked so that only one ESX Host can see the LUN, while the
datastore LUNS should be masked so that all ESX Hosts can see the LUNs
B. The Boot LUN and datastore LUNS should be masked so that all ESX Hosts can see the LUNs
C. The Boot LUN should be masked so that all ESX Hosts can see the LUN, while the datastore
LUNS should be masked so that only one ESX Host can see the LUNs
D. The Boot LUN and datastore LUNS should be masked so that only one ESX Host can see the
LUNs

Answer: A
Explanation:
iSCSI SAN Configuration Guide, page 14, 52.
Boot LUNs should only be visible to the server using that LUN to boot. No other server or system
on the SAN should be permitted to see that boot LUN.
ESX/ESXi and SAN Use Cases.
You can perform a number of tasks when using ESX/ESXi with SAN. Using ESX/ESXi in
conjunction with SAN is effective for the following tasks:
Maintenance with zero downtime
When performing an ESX/ESXi host or infrastructure maintenance, use VMware DRS or VMotion
to migrate virtual machines to other servers. If shared storage is on the SAN, you can perform
maintenance without interruptions to the user.
Load balancing
Use VMotion or VMware DRS to migrate virtual machines to other hosts for load balancing. If
shared storage is on a SAN, you can perform load balancing without interruption to the user.
To enable this functionality, shares storage is required - hence the datastore LUNS should be
masked so that all ESX Hosts can see the LUNs

QUESTION NO: 38
Which two are requirements when booting from SAN (Choose Two)?
A. The Storage Array port WWN specified in the BIOS configuration of the HBA must be passive
B. The HBA should be plugged into the lowest PCI bus and slot number
C. The boot LUN should only be visible to the ESX Server that is booting from it
D. The boot LUN should be visible to all ESX Servers for HA failover

A. BIOS File (.nvram)
B. VMotion Transfer File (.vmt)
C. Configuration File (.vmx)
D. Virtual Disk File (.vmdk)
E. Hardware File (.svr)

Answer: A,C,D
Explanation:
VMware File Extensions
VMDK -- These files are the actual hard disk of the virtual machine itself, and tend to be the
largest file within the folder. You can consider the size of this file to be roughly equivalent to the
size of either the disk itself (if you've chosen to use preallocated disks) or the size of the data
currently stored on that disk (if you use growable disks). [D above]
NVRAM -- Consider this file the BIOS of the virtual machine. [A above]
VMX -- With typically one VMX file per folder, this file holds the configuration information for the
virtual machine in a text format. [C above]
VMXF -- This file, in XML format, includes additional information about the virtual machine if it has
been added to a team. If a machine has been added to a team and then later removed, this file
remains resident. This file can also be opened and read in a text editor.
VMTM -- For virtual machines actively participating in a team, this file stores information about that
team membership.
VMEM -- These files, which contain a backup of the VMs paging file, are typically very small or
non-existent when the virtual machine is powered off, but grow immediately to the size of
configured RAM when the machine is powered on.
VMSN and .VMSD -- When snapshots are created for a virtual machine, these files are created to
host the state of the virtual machine.
VMSS -- If you've suspended the state of your machine, this file contains the suspended state of
that machine. These files typically only appear when virtual machines have been suspended.
HLOG -- If you have vMotioned the Virtual Machine, this file is created and can be safely deleted.

Explanation: VMware Server Get Started with Virtualization Risk-Free.
Can I manage VMware Server 2 release using an existing or new version of VMware vCenter
Server?
No, VMware Server 2 cannot be managed by VMware vCenter Server 2.5. There are no
centralized (multi-host) management options available for VMware Server 2. [Therefore
D is correct]. What is VMware Remote Console?
The VMware Remote Console allows access to the virtual machine consoles independent of the
VI Web Access management interface. A separate window is opened for every virtual machine
console that is initiated and the window can be resized as required by the user. Finally, VMware
Remote Console can be accessed directly from a desktop shortcut providing independent and
instantaneous access to the virtual machine console. [Therefore A is incorrect] Key Features
Supports two-processor Virtual SMP, enabling a single virtual machine to span multiple physical
processors [ Therefore B is incorrect]

Assuming VLANs are not configured, which of the following is true about traffic from a virtual
machine connected to a port group on a vNetwork Standard Switch with no uplinks?
A. Virtual machines in any port group on the virtual switch can receive the traffic
B. The virtual switch will drop the packets if no uplink is present
C. Virtual machines on any virtual switch on the same ESX/ESXi host can receive the traffic
D. Only virtual machines in the same port group on the virtual switch can receive the traffic

Answer: A
Explanation:
VMware Virtual Networking Concepts, page 6.
It is possible, and even reasonable, to assign the same VLAN ID to multiple port groups. This
would be useful if, for example, you wanted to give different groups of virtual machines different
physical Ethernet adapters in a NIC team for active use and for standby use, while all the adapters
are on the same VLAN.
Since a port group without an assigned VLAN has an implicit VLAN ID of 0, all port groups without
a VLAN ID will be in VLAN0. Multiple port groups with the same VLAN can communicate with each
other.
Physical Ethernet adapters serve as bridges between virtual and physical networks. In VMware
Infrastructure, they are called uplinks, and the virtual ports connected to them are called uplink
ports.
If no uplink exists there will be no communication with physical networks, but traffic will propagate
across virtual interfaces connected to the same switch.

QUESTION NO: 53

When an explicit failover order has not been configured on a virtual switch with multiple uplinks,
what determines which uplink is used when a failover event occurs?
A. The first available uplink that reports a positive Link State
B. The uplink with the shortest route
C. The next available uplink on the list
D. The reported uptime for the surviving uplinks

Answer: D
Explanation:
Networking Virtual Machines Jon Hall Technical Trainer, VMWORLD 2006, slide 27.
Failover is implemented by the VMkernel based upon configurable parameters
1. Failover order: Explicit list of preferred links (uses highest-priority link which is up)
2. 1. Maintains load balancing configuration
2. Good if using a lower bandwidth standby NIC
3. Rolling failover -- preferred uplink list sorted by uptime
The uplink with the shortest route - all uplinks are on the same network and so have the same
route The next available uplink on the list has not been defined if explicit failover order is not
selected

QUESTION NO: 64

E. I/O queuing to the physical storage HBAs

Answer: B,C,E
Explanation:
What is Pluggable Storage Architecture (PSA) and Native Multipathing (NMP)?
Pluggable Storage Architecture (PSA)
PSA is a collection of VMkernel APIs that allow third party hardware vendors to insert code directly
into the ESX storage I/O path. This allows 3rd party software developers to design their own load
balancing techniques and failover mechanisms for particular storage array.
The PSA coordinates the operation of the NMP and any additional 3rd party MPP.
Native Multipathing Plugin (NMP)
VMware provides a generic Multipathing Plugin (MPP), called Native Multipathing Plugin (NMP).
What does NMP do?
· Manages physical path claiming and unclaiming.
· Registers and de-registers logical devices.
· Associates physical paths with logical devices.
· Processes I/O requests to logical devices:
o Selects an optimal physical path for the request (load balance) [B above]
o Performs actions necessary to handle failures and request retries.
· Supports management tasks such as abort or reset of logical devices.[C above]
Since the NMP provides B and C, the PSA must perform A, D and E

QUESTION NO: 82
How many paths to a LUN can be simultaneously used when Round Robin multi-pathing is
enabled?
A. Round Robin will use only one path to send I/O
B. Round Robin can use up to 4 paths simultaneously to send I/O
C. Round Robin can be set to use additional paths simultaneously for every 1000 blocks of I/O
transmitted
D. Round Robin can use up to 2 paths simultaneously to send I/O

Answer: A
Explanation:
Fibre Channel SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 25.
Round Robin (RR) Uses a path selection algorithm that rotates through all available paths
enabling
load balancing across the paths.
Round-Robin Load Balancing
VMware ESX Server 3.5, VMware ESX Server 3i version 3.5, VMware VirtualCenter 2.5, page 1
When one path from the ESX Server host to the SAN becomes unavailable, the host switches to
another path. ESX Server hosts can also use multipathing for load balancing.
When to switch - Specify that the ESX Server host should attempt a path switch after a specified
number of I/O blocks have been issued on a path or after a specified number of read or write
commands have been issued on a path. If another path exists that meets the specified path policy
for the target, the active path to the target is switched to the new path.
Since the active path is switched to a new path, it can be assumed that only a single path is ever
used at any given time, (A above).

QUESTION NO: 83
What are two functions of zoning in Fibre Channel Switches (Choose Two)?
A. Reduces the number of targets and LUNs presented by a Fibre Channel Storage Array
B. Prevents non-ESX Hosts from possibly destroying VMFS data
C. Controls and isolates LUNs on a Fibre Channel Storage Array
D. Restrict connections on a storage array to ESX Hosts that utilize the array

Answer: B,D
Explanation:
Fibre Channel SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 53, page 15.
To restrict server access to storage arrays not allocated to that server, the SAN uses zoning. [A
above] Typically, zones are created for each group of servers that access a shared group of
storage devices and LUNs. Zones define which HBAs can connect to which SPs. Devices outside
a zone are not visible to the devices inside the zone. Since devices outside a zone are not visible
to the devices inside the zone it would rrevents non-ESX Hosts from accessing and possibly
destroying VMFS data. [B above]

QUESTION NO: 84
To prevent non-ESX Servers from seeing VMFS datastores, where should LUN masking be

When configuring a FC-SAN with ESX 4, which of the following are valid requirements and/or
recommendations (Choose Two)?
A. Each LUN must present the same LUN ID number to all ESX/ESXi hosts
B. RDMs should not be used to access raw disks from previous ESX 2.5 or 3.x Hosts
C. Virtual machine multipathing software should be used to perform I/O load balancing to
individual LUNs
D. Each LUN should contain only one VMFS datastore

multipathing, how many paths are used to send data to a VMFS Datastore at any given time?
A. 2
B. 1
C. 3
D. 4

Answer: B
Explanation:

QUESTION NO: 88
A virtual machine is using a Fibre Channel attached Raw Device Mapped (RDM) LUN. Which of
the following applications used with the virtual machine would require the RDM to be in Physical
Compatibility Mode (Choose Three)?
A. SAN Management Agents
B. Physical Server to Virtual Machine Clustering
C. Storage Array based Replication
D. VMware Snapshots
E. SCSI-target based software

Answer: A,B,E
Explanation:
Setup for Failover Clustering and Microsoft Cluster Service ESX 4.0 ESXi 4.0 vCenter Server 4.0,
page 25.
Cluster Physical and Virtual Machines
A standby host cluster has specific hardware and software requirements.
Use RDMs in physical compatibility mode (pass-through RDM). You cannot use virtual disks or
RDMs in virtual compatibility mode (non-pass-through RDM) for shared storage. [B is correct].
Physical compatibility mode allows the guest operating system to access the hardware directly.
Physical compatibility is useful if you are using SAN-aware applications in the virtual machine.
However, a virtual machine with the physical compatibility RDM cannot be cloned, made into a
template, or migrated if the migration involves copying the disk.
Virtual compatibility allows the RDM to behave as if it were a virtual disk, so you can use such
features as snapshotting, cloning, and so on. [Therefore D is incorrect].
Recommended Detailed Material on RDM's
Physical mode for the RDM specifies minimal SCSI virtualization of the mapped device, allowing
the greatest flexibility for SAN management software. In physical mode, the VMkernel passes all
SCSI commands to the device, with one exception: the REPORT LUNs command is virtualized, so
that the VMkernel can isolate the LUN for the owning virtual machine. Otherwise, all physical
characteristics of the underlying hardware are exposed. Physical mode is useful to run SAN
management agents [B above] or other SCSI target based software [E above] in the virtual
machine.

QUESTION NO: 89
A virtual machine has been configured with N-Port ID Virtualization. The Guest OS virtual disk is
placed in a RAID5 datastore, while the Production virtual disk is placed in a RAID1+0 datastore.
Why would an administrator consider placing both disks on the same datastore (Choose Two)?
A. VMotion can be used with NPIV enabled virtual machines, but not with disks in multiple
datastores
B. Storage VMotion cannot be used on a virtual machine with NPIV enabled
C. VMotion cannot be used on a virtual machine with NPIV enabled
D. Storage VMotion can be used with NPIV enabled virtual machines, but not with disks in multiple
datastores

Answer: A,B

QUESTION NO: 90
An administrator finds that a VMotion and Storage vMotion operations do not succeed on a virtual
machine. The virtual machine has been configured with N-Port ID Virtualization. The virtual
machine has two data RDMs, one using a RAID5 LUN and one using a RAID0+1 LUN. When
created, the mapping file for the RAID5 LUN was created on the same datastore as the virtual
machine, while the mapping file for the RAID0+1 LUN was placed in a datastore used for
production data virtual disks.
Which of the following statements are true about this configuration (Choose Two)?
A. VMotion cannot be used with NPIV
B. Storage VMotion cannot be used with NPIV
C. VMotion cannot be used unless both mapping files are placed on the same datastore
D. Storage VMotion cannot be used unless both mapping files are placed on the same datastore

Answer: B,C

QUESTION NO: 91
When writes from a virtual machine are delivered to a Fibre Channel Storage Array, which of the
following actions is taken by the VMkernel (Choose Three)?
A. The file corresponding to the virtual machine is located on the VMFS datastore
B. The I/O request is converted from binary data form to optical form
C. The modified I/O request is sent from the device driver to the physical HBA
D. The request for blocks on the virtual disk is mapped to blocks on the appropriate physical
device
E. The commands are forwarded by the virtual SCSI Controller

Answer: A,C,D
Explanation:
Fibre Channel SAN Configuration Guide ESX Server 3.5, ESX Server 3i version 3.5 VirtualCenter
2.5, page 40.
When a virtual machine interacts with a SAN, the following process takes place:
When the guest operating system in a virtual machine needs to read or write to SCSI disk, it
issues SCSI commands to the virtual disk.
Device drivers in the virtual machine's operating system communicate with the virtual SCSI
controllers. VMware ESX Server supports two types of virtual SCSI controllers: BusLogic and
LSILogic.
The virtual SCSI Controller forwards the command to the VMkernel.
The VMkernel:
Locates the file in the VMFS volume that corresponds to the guest virtual machine disk.
Maps the requests for the blocks on the virtual disk to blocks on the appropriate physical device.
Sends the modified I/O request from the device driver in the VMkernel to the physical HBA (host
HBA).
The host HBA:
Converts the request from its binary data form to the optical form required for transmission on the
fibre optic cable.
Packages the request according to the rules of the FC protocol.
Transmits the request to the SAN.
Depending on which port the HBA uses to connect to the fabric, one of the SAN switches receives
the request and routes it to the storage device that the host wants to access.

QUESTION NO: 92
The Runtime Name for a Fibre Channel storage device is equivalent to?
A. The Network Address Authority (NAA) name of the device
B. The name of the current path to the device in vmhba:C:T:L format
C. The Universally Unique Identifier (UUID) to the device
D. The name of the first discovered path to the device in vmhba:C:T:L format

Answer: D
Explanation:
Fibre Channel SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 53.
Runtime Name
The name of the first path to the device. The runtime name is created by the host. The name is not
a reliable identifier for the device, and is not persistent.
The runtime name has the following format:
vmhba#:C#:T#:L#, where
vmhba# is the name of the storage adapter. The name refers to the physical adapter on the host,
not to the SCSI controller used by the virtual machines.
C# is the storage channel number.
T# is the target number. Target numbering is decided by the host and might change if there is a
change in the mappings of targets visible to the host. Targets that are shared by different hosts
might not have the same target number.
L# is the LUN number that shows the position of the LUN within the target. The LUN number is
provided by the storage system. If a target has only one LUN, the LUN number is always zero (0).
For example, vmhba1:C0:T3:L1 represents LUN1 on target 3 accessed through the storage
adapter vmhba1 and channel 0.

QUESTION NO: 93
How are new LUNs discovered by an ESX Host?
A. A rescan operation is required every time a new LUN is added
B. ESX Server automatically detects new LUNs as they are presented
C. ESX Server periodically performs a rescan operation to detect any new LUNs
D. A reboot operation is required to detect newly presented LUNs

Answer: A
Explanation:
iSCSI SAN Configuration Guide, page 26.
The VMkernel discovers LUNs when it boots, and those LUNs are then visible in the vSphere
Client. If changes are made to the LUNs, you must rescan to see those changes.
New LUNs created on the iSCSI storage
Changes to LUN access control
Changes in connectivity

An administrator is configuring software iSCSI multipathing. Which of the following is the minimum
required configuration for Round Robin multipathing?
A. Configure 1 VMkernel port. Bind the port to multiple uplinks on the same virtual switch. Choose
the Round Robin Path Selection Plugin (PSP)
B. Configure 2 VMkernel ports. Connect each port to a unique virtual switch with uplinks on
separate subnets. Choose the Round Robin Path Selection Plugin (PSP)
C. Configure 1 VMkernel port. Connect the port to a switch with multiple uplinks. Choose the
Round Robin Path Selection Plugin (PSP)
D. Configure 2 VMkernel ports. Bind each port to a different uplink on the same virtual switch.
Choose the Round Robin Path Selection Plugin (PSP)

Answer: D
Explanation:
D "Multivendor Post" on using iSCSI with VMware vSphere
So - setup in 4 easy steps:
Step 1 - configure multiple vmkNICs
Ok, the first obvious (but we're not making any assumptions) is that you will need to configure
multiple physical Ethernet interfaces, and multiple vmkernel NIC (vmkNIC) ports.
Step 2 - configure explicit vmkNIC-to-vmNIC binding.
To make sure the vmkNICs used by the iSCSI initiator are actual paths to storage, ESX
configuration requires the vmkNIC is connected to a portgroup that only has one active uplink and
no standby uplinks. This way, if the uplink is unavailable, the storage path is down and the storage
multipathing code can choose a different path.
Step 3 - configuring the iSCSI initiator to use the multiple vmkNICs
Then the final step requires command line configuration. This step is where you assign, or bind,
the vmkNICs to the ESX iSCSI initiator. Once the vmkNICs are assigned, the iSCSI initiator uses
these specific vmkNICs as outbound ports, rather than the vmkernel routing table.
Step 4 - Enabling Multipathing via the Pluggable Storage Architecture
VMware ships with a set of native SATPs, and 3 PSPs: Fixed, Most Recently Used (MRU), &
Round Robin (RR). Fixed and MRU options were available in VI3.x and should be familiar to
readers. Round Robin was experimental in VI3.5, and is supported for production use in vSphere
(all versions)
Configuring NMP to use a specific PSP (such as Round Robin) is simple and easy. You can do it
in the vSphere Client under configuration, storage adapter, select the devices, and right click for
properties.

QUESTION NO: 96

Which of the following CHAP Authentication mechanisms is available when using Software iSCSI,
but not Hardware iSCSI? Select all that apply.
A. Per-Target CHAP
B. Per-Subnet CHAP
C. Mutual CHAP
D. One-way CHAP

Answer: A,C
Explanation:
Software iSCSI support BOTH Per-Target and Mutual CHAP.
For Softare iSCSI only, you can set one-way CHAP and mutual CHAP for each initiator or at the
target level.
Hardware iSCSI support CHAP only at the initiator level.
iSCSI SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 37.
ESX/ESXi supports CHAP authentication at the adapter level. In this case, all targets receive the
same CHAP name and secret from the iSCSI initiator. For software iSCSI, ESX/ESXi also
supports per-target CHAP authentication, which allows you to configure different credentials for
each target to achieve greater level of security.

D. The virtual switch

Answer: B,D
Explanation:
iSCSI SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 30.
If needed, enable Jumbo Frames. Jumbo Frames must be enabled for each vSwitch through the
vSphere CLI. Also, if you use an ESX host, you must create a VMkernel network interface enabled
with Jumbo Frames.

QUESTION NO: 99
Using Hardware iSCSI Initiators with ESX/ESXi hosts allows which of the following tasks to be
offloaded from the VMkernel?
A. Issuing SCSI commands to the virtual disk
B. Encapsulation of I/O requests into iSCSI Protocol Data Units (PDUs)
C. Encapsulation of iSCSI PDUs into TCP/IP packets
D. Mapping requests for blocks on the virtual disk to blocks on the appropriate physical device

Answer: B,C
Explanation:
iSCSI From Wikipedia, the free encyclopedia
An initiator functions as an iSCSI client. An initiator typically serves the same purpose to a
computer as a SCSI bus adapter would, except that instead of physically cabling SCSI devices
(like hard drives and tape changers), an iSCSI initiator sends SCSI commands over an IP network.
An initiator falls into two broad types:
Software initiator
A software initiator uses code to implement iSCSI. Typically, this happens in a kernel-resident
device driver that uses the existing network card (NIC) and network stack to emulate SCSI devices
for a computer by speaking the iSCSI protocol. Software initiators are available for most
mainstream operating systems, and this type is the most common mode of deploying iSCSI on
computers.
Hardware initiator
A hardware initiator uses dedicated hardware, typically in combination with software (firmware)
running on that hardware, to implement iSCSI. A hardware initiator mitigates the overhead of
iSCSI [B above] and TCP [A above] processing and Ethernet interrupts, and therefore may
improve the performance of servers that use iSCSI.

QUESTION NO: 100
Using Hardware iSCSI Initiators with ESX/ESXi hosts allows which of the following tasks to be
offloaded from the VMkernel (Choose Two)?
A. Encapsulation of I/O requests into iSCSI Protocol Data Units (PDUs)
B. Mapping requests for blocks on the virtual disk to blocks on the appropriate physical device
C. Encapsulation of iSCSI PDUs into TCP/IP packets
D. Issuing SCSI commands to the virtual disk

Answer: A,C
Explanation:
iSCSI SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 19.
If the iSCSI initiator is a hardware iSCSI initiator (iSCSI HBA), the HBA performs the following
tasks.
Encapsulates I/O requests into iSCSI Protocol Data Units (PDUs). [A above]
Encapsulates PDUs into TCP/IP packets. [C above]
Sends IP packets over Ethernet to the iSCSI storage system.

QUESTION NO: 101
A company wants to increase disk capacity for their VMware vSphere environment Management
mandates that:
(1) VMotion must work in this environment
(2) the existing LAN infrastructure must be used
(3) the storage must support VMFS volumes
Which storage option would best meet company objectives?
A. NFS
B. Fibre Channel
C. iSCSI
D. SATA

Answer: C
Explanation:
iSCSI SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 9, 13, 16.
Overview of Using ESX/ESXi with a SAN
Using ESX/ESXi with a SAN improves flexibility, efficiency, and reliability. Using ESX/ESXi with a
SAN also supports centralized management and failover and load balancing technologies.
The following are benefits of using ESX/ESXi with a SAN:
You can perform live migration of virtual machines using VMware Vmotion.
Therefore this option would meet requirement (1) VMotion must work in this environment
iSCSI SANs use Ethernet connections between computer systems, or host servers, and highperformance
storage subsystems. The SAN components include host bus adapters (HBAs) or
Network Interface Cards (NICs) in the host servers, switches and routers that transport the storage
traffic, cables, storage processors (SPs), and storage disk systems
Therefore this option would meet requirement (2) the existing LAN infrastructure must be used
Use the vSphere Client to set up a VMFS datastore in advance on any SCSI-based storage device
that your ESX/ESXi host discovers. A VMFS datastore can be extended over several physical
storage extents, including SAN LUNs and local storage. This feature allows you to pool storage
and gives you flexibility in creating the storage volume necessary for your virtual machine.
Therefore this option would meet requirement (3) the storage must support VMFS volumes

An ESX Host gains exclusive access to Virtual Machines created on NFS datastores using which
of the following mechanisms?
A. SCSI Reservations
B. a special .lck-XXX lock file
C. NFS File Locking Protocol
D. Distributed File Locking

Answer: B
Explanation:
ESX ESX Configuration Guide ESX 4.0 vCenter Server 4.0
When your host accesses a virtual machine disk file on an NFS-based datastore, a .lck-XXX lock
file is generated in the same directory where the disk file resides to prevent other hosts from
accessing this virtual disk file. Do not remove the .lck-XXX lock file, because without it, the running
virtual machine cannot access its virtual disk file.

B. Virtual Machine Snapshots
C. Storage VMotion
D. Raw Device Mapping
E. MSCS Clustering

Answer: A,B,C
Explanation:
VMware Infrastructure Automating High Availability (HA) Services with VMware HA, page 15.
There are a few basic requirements that your virtual infrastructure system and hosts need to meet
so that VMware cluster and HA features operate properly. First, for clusters enabled for VMware
HA, all virtual machines and their configuration files must reside on shared storage (Fibre Channel
SAN, iSCSI SAN, or SAN iSCI NAS), because you need to be able to power on the virtual
machine on any host in the cluster. [A above]
Introduction to VMware vSphere ESX 4.0 ESXi 4.0 vCenter Server 4, page 19 and 20.
Each datastore is a physical VMFS volume on a storage device. NAS datastores are an NFS
volume with VMFS characteristics. VMFS also features failure consistency and recovery
mechanisms, such as distributed journaling, a failure consistent virtual machine I/O path, and
machine state snapshots. These mechanisms can aid quick identification of the cause and
recovery from virtual machine, physical host, and storage subsystem failures [B above]
What Is New in VMware vSphere™ 4: Storage, page 7.
vSphere introduces several new capabilities to Storage VMotion. When Storage VMotion was
introduced in VI3 release 3.5, it had a few limitations which vSphere 4 addresses. Storage
VMotion is now fully integrated into vCenter and offers full support for migration across datastores
of several protocol choices. Hence the enhanced Storage VMotion capabilities fall squarely in the
realm of how vSphere provides an increased set of choices. First the ability to move a VM home
from one datastore to another while changing the storage protocol in the process. The source
datastore might be FC, iSCSI, or NFS, and the target datastore any of those three. [C above]

Storage vMotion) don't work with pRDMs.
VMware -Raw Device Mapping (RDM)
With Physical compatibility mode you VM can access LUN directly. This is generally used from the
application inside VM wants to directly access LUN. However using physical compatibility mode
you lose the option to clone a VM, make it a template and migration when it involves moving disks.

Which of the following are accurate descriptions of the Predictive and Adaptive Schemes for
placing VMFS datastores (Choose Two)?
A. The Predictive Scheme utilizes several LUNs with different storage characteristics
B. The Predictive Scheme utilizes a small number of large LUNs
C. The Adaptive Scheme utilizes a small number of large LUNs
D. The Adaptive Scheme utilizes several LUNs with different storage characteristics

Answer: A,C
Explanation:
Making LUN Decisions.
In the predictive scheme, you:
· Create several LUNs with different storage characteristics. (B above)
· Build a VMFS volume in each LUN (label each volume according to its characteristics).
·Locate each application in the appropriate RAID for its requirements.
·Use disk shares to distinguish high-priority from low-priority virtual machines. Note that disk
shares are relevant only within a given ESX Server host. The shares assigned to virtual machines
on one ESX Server host have no effect on virtual machines on other ESX Server hosts.
In the adaptive scheme, you:
·Create a large LUN (RAID 1+0 or RAID 5), with write caching enabled. (A above)
·Build a VMFS in that LUN.
·Place four or five virtual disks on the VMFS.
·Run the applications and see whether disk performance is acceptable.
If performance is acceptable, you can place additional virtual disks on the VMFS. If it is not, you
create a new, larger LUN, possibly with a different RAID level, and repeat the process. You can
use cold migration so you don't lose virtual machines when recreating the LUN.

using DHCP

Answer: B,D,E
Explanation:
ESX and vCenter Server Installation Guide, ESX 4.0, vCenter Server 4.0 Page 16, 83-84.
The vCenter Server system is a physical machine or virtual machine with access to a supported
database. [D above]
The system that you use for your vCenter Server installation must belong to a domain rather than
a workgroup. If assigned to a workgroup, the vCenter Server system is not able to discover all
domains and systems available on the network when using such features as vCenter Guided
Consolidation Service. [B above]
This paragraph is highly confusing, as it contradicts itself. However, in fact vCenter Server can be
installed to a system residing in a workgroup, as shown below.
vCenter Server, like any other network server, should be installed on a machine with a fixed IP
address and well-known DNS name, so that clients can reliably access the service. If you use
DHCP instead of a static IP address for vCenter Server, make sure that the vCenter Server
computer name is updated in the domain name service (DNS). [E above]
