Q

What command must be issued on a Cisco router that will serve as an authoritative NTP server?

clock set 11:00:00 DEC 20 2010.
ntp master 1.
ntp server 172.16.0.1.
ntp broadcast client.

A

ntp master 1.

17
Q

Which protocol or service can be configured to send unsolicited messages to alert the network administrator about a network event such as an extremely high CPU utilization on a router?

SNMP.
Syslog.
NTP.
NetFlow.

A

SNMP.

18
Q

Which statement describes a syslog message severity level?

A syslog alarm at the severity level 4 and higher is sent to an external syslog server by default.

Severity level 0 is the most critical severity level.

A syslog alarm with a severity level of 7 indicates an emergency situation that can render the system unusable.

A severity level 7 message is only accessible through the terminal line.

A

Severity level 0 is the most critical severity level.

19
Q

What is an SNMP management agent?

a computer loaded with management software and used by an administrator to monitor a network.

A communication protocol that is used by SNMP.

A database that a device keeps about network performance.

Software that is installed on devices managed by SNMP.

A

Software that is installed on devices managed by SNMP.

20
Q

What are two characteristics of SNMP community strings? (Choose two.)

Commonly known community strings should be used when configuring secure SNMP.

SNMP read-write community strings can be used to set information on an SNMP-enabled device.

A vulnerability of SNMPv1, SNMPv2, and SNMPv3 is that they send the community strings in plaintext.

If the manager sends one of the correct read-only community strings, it can get information and set information in an agent.

SNMP read-only community strings can be used to get information from an SNMP-enabled device.

A

SNMP read-write community strings can be used to set information on an SNMP-enabled device.

SNMP read-only community strings can be used to get information from an SNMP-enabled device.

21
Q

A network administrator issues the copy tftp running-config command on a router. What is the administrator trying to achieve?

Copy the configuration file from the TFTP server to the RAM of the router.

Copy the configuration file from the NVRAM of the router tp the TFTP server.

Copy the configuration file from the TFTP server to the NVRAM of the router.

Copy the configuration file from the RAM of the router to the TFTP server.

A

Copy the configuration file from the TFTP server to the RAM of the router.

22
Q

What is a characteristic of the MIB?

A separate MIB tree exists for any given device in the network.​

The OIDs are organized in a hierarchical structure.

Information in the MIB cannot be changed.

Information is organized in a flat manner so that SNMP can access it quickly.

A

The OIDs are organized in a hierarchical structure.

23
Q

What data would be saved and where would the data be placed if a network administrator issued the following command? (Choose two.)

R1# copy startup-config tftp

The data will be saved in RAM.

The data to be saved is the configuration that is stored in NVRAM.

The data will be saved to a TFTP server.

The data will be saved in NVRAM.

The data to be saved is the configuration that is being modified in RAM.

The data to be saved is the configuration that is stored on a TFTP server.

A

The data to be saved is the configuration that is stored in NVRAM.

The data will be saved to a TFTP server.

24
Q

Which command would a network engineer use to restore the IOS image c1900-universalk9-mz.SPA.152-4.M3.bin to a router?

copy flash0:c1900-universalk9-mz.SPA.152-4.M3.bin

copy tftp:flash0:

copy flash0:tftp:

A

copy tftp:flash0:

25

to display router ID and other information about OSPF neighbors.

to display routing table and other information about directly connected Cisco devices.

to display line status and other information about directly connected Cisco devices.

to display device ID and other information about directly connected Cisco devices.

A

to display device ID and other information about directly connected Cisco devices.

26
Q

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.

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

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

A

unsolicited messages that are sent by the SNMP agent and alert the NMS to a condition on the network.
