What is a characteristic of the Cisco IOS Resilient Configuration feature?
It maintains a secure working copy of the bootstrap startup program.

Once issued, the secure boot-configcommand automatically upgrades the configuration archive to a newer version after new configuration commands have been entered.

A snapshot of the router running configuration can be taken and securely archived in persistent storage.

The secure boot-image command works properly when the system is configured to run an image from a TFTP server.
A snapshot of the router running configuration can be taken and securely archived in persistent storage.
What service or protocol does the Secure Copy Protocol rely on to ensure that secure copy transfers are from authorized users?
SNMP
AAA
IpSec
Radius
AAA
Which statement describes SNMP operation?
An SNMP agent that resides on a managed device collects information about the device and stores that information remotely in the MIB that is located on the NMS.

A get request is used by the SNMP agent to query the device for data.

A set request is used by the NMS to change configuration variables in the agent device.

An NMS periodically polls the SNMP agents that are residing on managed devices by using traps to query the devices for data.
A set request is used by the NMS to change configuration variables in the agent device.
Which service is enabled on a Cisco router by default that can reveal significant information about the router and potentially make it more vulnerable to attack?
Telnet
CDP
LLDP
SSH
CDP
What is the purpose of issuing the ip ospf message-digest-key key md5 password command and the area area-id authentication message-digest command on a router?
To enable OSPF MD5 authentication on a per-interface basis.
To facilitate the establichment of neighbor adjacencies.
To configure OSPF MD5 authentication globally on the router.
To encrypt OSPF routing updates.
To configure OSPF MD5 authentication globally on the router.
When password recovery on a router is being performed and the settings in NVRAM have been bypassed, which step should be taken next?
Reload the Router.
Reset the Router.
Copy the contents of the RAM to the NVRAM.
Copy the contents of the NVRAM to the RAM.
Copy the contents of the NVRAM to the RAM.
Which service should be disabled on a router to prevent a malicious host from falsely responding to ARP requests with the intent to redirect the Ethernet frames?
LLDP
CDP
proxy ARP
reverse ARP
proxy ARP
Which technology allows syslog messages to be filtered to different devices based on event importance?
Syslog service timestamps.
Syslog severity levels.
Syslog service identifiers.
Syslog facilities.
Syslog severity levels.
When SNMPv1 or SNMPv2 is being used, which feature provides secure access to MIB objects?
Community strings.
Message integrity.
Packet encryption.
Source validation.
Destination validation.
Community strings.
A network engineer wants to synchronize the time of a router with an NTP server at the IPv4 address 209.165.200.225. The exit interface of the router is configured with an IPv4 address of 192.168.212.11. Which global configuration command should be used to configure the NTP server as the time source for this router?
ntp server 209.165.200.225
ntp server 209.165.200.0
ntp server 192.168.212.11
ntp server s0/0/0
ntp server 209.165.200.225
Which protocol or service is used to automatically synchronize the software clocks on Cisco routers?
Question options:
NTP
DNS
SNMP
STP
NTP
What are two reasons to enable OSPF routing protocol authentication on a network? (Choose two.)
To ensure faster network convergence.
To provide data security through encryption.
To prevent data traffic from being redirected and then discarded.
To ensure more efficient routing.
To prevent redirection of data traffic to an insecure link.
To prevent data traffic from being redirected and then discarded.
To prevent redirection of data traffic to an insecure link.
What are SNMP trap messages?
Unsolicited messages that are sent by the SNMP agent and alert the NMS to a condition on the network

Messages that are used by the NMS to change configuration variables in the agent device.

Messages that are used by the NMS to query the device for data.

Messages that are sent periodically by the NMS to the SNMP agents that reside on managed devices to query the device for data.
Unsolicited messages that are sent by the SNMP agent and alert the NMS to a condition on the network
What are three functions provided by the syslog service? (Choose three.)
To specify the destinations of captured messages.
To periodically poll agents for data.
To gather logging information for monitoring and troubleshooting.
Enable DTP on all trunk ports.
To select the type of logging information that is captured.
To specify the destinations of captured messages.
