CCNA 4 Chapter 8 v5.0 Exam Answers 2014

1.



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

This message resulted from an unusual error requiring reconfiguration of the interface.

This message indicates that the interface should be replaced.

This message is a level 5 notification message.

This message indicates that service timestamps have been configured.

This message indicates that the interface changed state five times.

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?

Branch1(config)# service timestamps log uptime

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

Branch1(config)# service timestamps debug datetime

Branch1# copy running-config startup-config

3.



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

syslog server

syslog client

router RAM

router NVRAM

4.



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

the time passed since the syslog server has been started

the time when the syslog message was issued

the time passed since the interfaces have been up

the time on the router when the show logging command was issued

5. What are SNMP trap messages?

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

messages that are sent periodically by the NMS to the SNMP agents that reside on managed devices to query the device for

data

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

Use the snmp-server community command to configure the community string with no access level.

Specify the IP address of the SNMP manager by using the snmp-server host command.

Use the snmp-server traps command to enable traps on an SNMP manager.

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

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?

No traps are sent, because the notification-types argument was not specified yet.

Traps are sent with the source IP address as 10.10.50.25.

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

The snmp-server enable traps command needs to be used repeatedly if a particular subset of trap types is desired.

8. What is a difference between SNMP and NetFlow?

Unlike NetFlow, SNMP uses a “push”-based model.

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

SNMP only gathers traffic statistics, whereas NetFlow can also collect many other performance indicators, such as interface

errors and CPU usage.

Unlike NetFlow, SNMP may be used to provide IP accounting for billing purposes.

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

Netflow captures and analyzes traffic.

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

On 2960 switches, Netlow allows for data export.

NetFlow does not consume any additional memory.

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

the NetFlow version that is enabled

whether NetFlow is configured on the correct interface and in the correct direction

the configuration of the export parameters

the protocol that uses the largest volume of traffic

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

to support accounting and monitoring with consumer applications

to actively capture traffic from networked devices

to monitor live data usage and to control traffic flow with set messages

to passively capture changing events that occur in the network and to perform after-the-fact-analysis

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

RAM

NVRAM

nearest syslog server

console

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

SNMP community strings

SNMP set messages

SNMP get messages

SNMP trap messages

14. Which statement describes SNMP operation?

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.

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.

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

After four events, the syslog client will send an event message to the syslog server.

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

The syslog client will send to the syslog server event messages with an identification trap level of only 4.

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