Question 1

Refer to the exhibit. Which two conclusions can be drawn from the syslog message that was generated by the router? (Choose two.)

Answer 1

1. This message is a level 5 notification message.

2. This message indicates that service timestamps have been configured.

Question 2

A network technician has issued the service timestamps log datetime command in the configuration of the branch router. Which additional command is required to include the date and time in logged events?

Answer 2

Branch1# clock set 08:00:00 05 AUG 2013

Question 3

Refer to the exhibit. From what location have the syslog messages been retrieved?

Answer 3

router RAM

Question 4

Refer to the exhibit. What does the number 17:46:26.143 represent?

Answer 4

the time when the syslog message was issued

Question 5

What are SNMP trap messages?

Answer 5

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

Question 6

How can SNMP access be restricted to a specific SNMP manager?

Answer 6

Define an ACL and reference it by using the snmp-server community command.

Question 7

A network administrator issues two commands on a router:
R1(config)# snmp-server host 10.10.50.25 version 2c campus
R1(config)# snmp-server enable traps
What can be concluded after the commands are entered?

Answer 7

If an interface comes up, a trap is sent to the server.

Question 8

What is a difference between SNMP and NetFlow?

Answer 8

NetFlow collects more detailed traffic statistics on IP networks than SNMP does.

Question 9

How does NetFlow function on a Cisco router or multilayer switch?

Answer 9

One user connection to an application exists as two NetFlow flows.

Question 10

Which type of information can an administrator obtain with the show ip cache flow command?

Answer 10

the protocol that uses the largest volume of traffic

Question 11

What is the most common purpose of implementing NetFlow in a networked environment?

Answer 11

to support accounting and monitoring with consumer applications

Question 12

Which destination do Cisco routers and switches use by default when sending syslog messages for all severity levels?

Answer 12

console

Question 13

Which SNMP feature provides a solution to the main disadvantage of SNMP polling?

Answer 13

SNMP trap messages

Question 14

Which statement describes SNMP operation?

Answer 14

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

Question 15

A network administrator has issued the logging trap 4 global configuration mode command. What is the result of this command?

Answer 15

The syslog client will send to the syslog server any event message that has a severity level of 4 and lower.

Question 16

When logging is used, which severity level indicates that a device is unusable?

Answer 16

Emergency-Level 0

Question 17

Refer to the exhibit. While planning an upgrade, a network administrator uses the Cisco NetFlow utility to analyze data flow in the current network. Which protocol used the greatest amount of network time?

Answer 17

UDP-other

Question 18

Which two statements describe items to be considered in configuring NetFlow? (Choose two.)

Answer 18

1. Netflow can only be used in a unidirectional flow.

2. Netflow consumes additional memory.

Question 19

When SNMPvl or SNMPv2 is being used, which feature provides secure access to MIB objects?

Answer 19

community strings

Question 20

Refer to the exhibit. What can be concluded from the produced output?

Answer 20

An ACL was configured to restrict SNMP access to an SNMP manager.

Question 21

What are the most common syslog messages?

Answer 21

linkup and link down messages

Question 22

A network administrator has issued the snmp-server user adminl admin v3 encrypted auth md5 abc789 priv des 256 key99 command. What are two features of this command? (Choose two.)

Answer 22

1. It uses the MD5 authentication of the SNMP messages.

2. It adds a new user to the SNMP group.
