vSphere Distributed Resource Scheduler (DRS)Allocates and balances computing capacity dynamically across collections of hardware resources for virtual machines.vSphere Storage DRSAllocates and balances storage capacity and I/O dynamically across collections of datastores. This feature includes management capabilities that minimize the risk of running out of space and the risk of I/O bottlenecks slowing the performance of virtual machines.vSphere Fault Tolerance (FT)This feature maintains a secondary copy of a virtual machine. If the virtual machine becomes unavailable, the secondary machine becomes immediately active.vSphere Distributed Switch (VDS)A virtual switch that can span multiple ESXi hosts, enabling significant reduction of on-going network maintenance activities and increasing network capacity.Host ProfilesA feature that simplifies host configuration management through user-defined configuration policies.vSphere Auto DeployFacilitates rapid server deployment and provisioning of vSphere hosts by leveraging the network boot capabilities of x86 servers together with the small footprint of the ESXi hypervisor.vAppA format for packaging and managing applications and the virtual machines they run on.Data Center VirtualizationThe conversion of hardware devices into software resources.Availability, Scalability, Optimization, ManagementThe challenges of Data Center Virtualization.SnapshotAllows you to capture the entire running state of a virtual machine, from the contents of its hard disks to the state of its CPU and memory. Not designed for daily backups.Bare-Metal BackupA complete image-based backup of a virtual machine while its running.Bare-MetalType of backup that allows the restoration of individual files.FalseBare-Metal Backups can only be restored to the device where it was backed up. True or False?Hot AddFeature that allows you to increase the capabilities of a virtual machine without restarting it.Image-based Backups.Another name for Bare-Metal Backups.HypervisorProvides the virtual hardware.HypervisorActs as a Resource Traffic Cop.Bare-MetalType of Hypervisor installed on a physical device without an operating system.HostedType of Hypervisor installed as an application on top of a pre-existing operating system.VMware ESXiExample of a Bare-Metal Hypervisor.VMware WorkstationExample of a Hosted Hypervisor.Bare-MetalType of Hypervisor typically used in Data Center Virtualization.Hard Drives, Flash Drives, SD Cards, USB DrivesESXi installation options.TrueESXi hosts can be network booted. True or False?PXE, TFTPESXi network boot options.vCenterCentral management solution that can manage all your ESXi hosts in a single view.vCenter ComponentsIdentity Management Server, Database Server, Application Server, Web Server, vSphere Web Client.1000Number of ESXi hosts a single vCenter server can manage.10000Number of powered-on virtual machines a single vCenter server can manage.vSphere Distributed Power Management (DPM)Can be used to power-off unused ESXi hosts in your environment, or power-on ESXi hosts when necessary.vSphere Storage DRSAutomates load balancing from a storage perspective.vSphere Data Protection (VDP)Provides the ability to back up virtual machines.High Availability (HA)Restarts virtual machines on another host if you have a hardware problem.Fault Tolerance (FT)Provides uninterrupted availability for virtual machines.vSphere Replication (VR)Can copy virtual machines to another site for disaster recovery purposes.vSphere vMotion (vMotion)Allows hardware maintenance during the day without downtime.VMware Virtual Machine (VM)A large chunk of memory on an ESXi host.FalsevMotion requires shared storage. True or False?vSphere Distributed Resource Scheduler (DRS)Automated use of vMotion for policy-based balancing of virtual machines across ESXi hosts.vSphere Distributed Power Management (DPM)Consolidates (via DRS) virtual machines to fewer hosts during non-peak times.TrueStorage vMotion can migrate VMs from any supported storage type to another, including local storage devices. True or False?Storage I/O ControlControls the storage usage of busy virtual machines so that other virtual machines can still get an appropriate amount of storage performance.vSphere Data Protection (VDP)Leverages data duplication to make backup storage usage more efficient.vSphere API for Data Protection (VADP)API that allows 3rd party software vendors to create image-based backups of virtual machines.vSphere High Availability (HA)Can monitor the status of ESXi hosts, VMs, and Applications.FalsevSphere HA prevents virtual machines from crashing. True or False?HypericEnables vSphere HA to monitor Applications.Fault Tolerance (FT)A form of active/passive clustering that can perpetually mirror a running virtual machine to another ESXi host to prevent application data loss and corruption.Shared StorageStorage visible to multiple ESXi hosts typically used to store VMs and ISO files.Shared StorageDRS, DPM, Storage DRS, HA, and FT all require this to work.Fibre Channel, Fibre Channel over Ethernet, iSCSI, NFS, LocalThe types of Shared Storage supported by vSphere.vSphere Storage Appliance (VSA)A component of vSphere that allows you to create shared storage from the local storage devices in your ESXi hosts.vFlashA technology to leverage internal SSD drives to accelerate the read performance of virtual machines.DatastoresContainers for storing virtual machines. These containers are logical volumes that allow you to organize the storage of ESXi hosts and virtual machines.VMFS, NFSThe two types of datastores.iSCSI, NFS, FCoEThe three types of IP Storage.Virtual SwitchAttaches virtual machines to a physical network.Standard, DistributedThe two types of virtual network switches.Standard Virtual SwitchManages virtual machine networking at the host level.Distributed Virtual SwitchManages virtual machine networking at the data center level.VLANsProvides logical separation of network traffic, and are often used to isolate different subnets.Traffic ShapingAllows you to restrict the inbound and outbound network bandwidth of a group of virtual machines.Port MirroringAllows you to capture a virtual machine's traffic for troubleshooting or intrusion prevention.VLANs, Traffic Shaping, Port Mirroring, QoS & DSCP, CDP/LLDPvSphere's networking features.QoS, DSCPNetworking standards that allow network switches to prioritize certain network traffic over others.CDP, LLDPDiscovery protocols used to identify neighboring physical network switches.vCenter Operations Manager (vCOPS)Monitors performance and capacity trends to generate health, risk, and inefficiency super metrics based on dynamically adjusting thresholds.vCenter Configuration Manager (vCCM)Monitors the configuration of vCenter, ESXi hosts, and VMs, notifies you about changes, and helps correlate current problems to those changes.vCenter Site Recovery Manager (SRM)An orchestration tool for disaster recovery and data center migration that facilitates VM and storage replication.Virtual Machines (VMs)A cost-effective way to scale out to additional servers to have better application isolation.Hot AddThe ability to add more CPUs and memory to servers without incurring downtime.vSphere Storage Appliance (VSA)Provides a way to have virtual servers without a shared storage infrastructure.vSphere Distributed Resource Scheduler (DRS)An automated way to track and correct hot spots on ESXi hosts.vSphere Storage DRSAn automated way to track and correct hot spots on storage arrays.Thin ProvisioningA way to make more efficient use of unused space on large disk drives.vCenter Operations Manager (vCOPS)Helps identify performance bottlenecks on servers.vCenter Operations Manager (vCOPS)Provides detailed performance reports and proactive notifications to help identify immediate and trending performance problems.VM Storage ProfilesAn automatic way to map servers to their appropriate storage class.Virtual Machines (VMs)A way to reduce power and cooling requirements for existing servers.vCenterA central management solution to keep track of complex, distributed server environments.vCenter Configuration Manager (vCCM)A solution for monitoring server environments for unexpected changes for identify regulatory compliance issues.
