Which syslog message type is accessible only to an administrator and only via the Cisco CLI?
The command ntp server 10.1.1.1 is issued on a router. What impact does this command have?
determines which server to send system log files to
ensures that all logging will have a time stamp associated with it
identifies the server on which to store backup configurations
synchronizes the clock of the device to the timeserver that is located at IP address 10.1.1.1
A network administrator has issued the logging trap 4 global configuration mode command. What is the result of this command?
The syslog client will send to the syslog server event messages with an identification trap level of only 4.
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 lower.
The syslog client will send to the syslog server any event message that has a severity level of 4 and higher.
Which protocol is used by network administrators to track and gather statistics on TCP/IP packets that are entering or exiting network devices?
Which SNMP version uses weak community string-based access control and supports bulk retrieval?
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?
Traps are sent with the source IP address as 10.10.50.25.
The snmp-server enable traps command needs to be used repeatedly if a particular subset of trap types is desired.
No traps are sent, because the notification-types argument was not specified yet.
If an interface comes up, a trap is sent to the server.
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?

Critical - Level 2
Emergency - Level 0
Alert - Level 1
Error - Level 3

What is the most common purpose of implementing NetFlow in a networked environment?
to support accounting and monitoring with consumer applications
to passively capture changing events that occur in the network and to perform after-the-fact-analysis
to actively capture traffic from networked devices
to monitor live data usage and to control traffic flow with set messages
Which statement describes SNMP operation?
A get request is used by the SNMP agent to query the device for data.
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
A set request is used by the NMS to change configuration variables in the agent device.
How does NetFlow function on a Cisco router or multilayer switch?
On 2960 switches, Netlow allows for data export.
NetFlow does not consume any additional memory
One user connection to an application exists as two NetFlow flows
Netflow captures and analyzes traffic
Which SNMP feature provides a solution to the main disadvantage of SNMP polling?
SNMP set messages
SNMP community strings
SNMP trap messages
SNMP get messages
A user in a large office calls technical support to complain that a PC has suddenly lost connectivity to the network. The technician asks the caller to talk to nearby users to see if other machines are affected. The caller reports that several immediate neighbors in the same department have a similar problem and that they cannot ping each other. Those who are seated in other departments have connectivity. What should the technician check as the first step in troubleshooting the issue?
the trunks between switches in the wiring closet
the cable that connects the PC of the caller to the network jack
the status of the departmental workgroup switch in the wiring closet
the cable connection between a PC and a network outlet that is used by a neighbor
the power outlet to the PC that is used by the caller
When should a network performance baseline be measured?
after normal work hours to reduce possible interruptions
during normal work hours of an organization
immediately after the main network devices restarted
when a denial of service attack to the network is detected and blocked
What is a purpose of establishing a network baseline?
It manages the performance of network devices
It provides a statistical average for network performance
It creates a point of reference for future network evaluations
It checks the security configuration of network devices
A network technician is troubleshooting an email connection problem. Which question to the end-user will provide clear information to better define the problem?
When did you first notice your email problem?
What kind of equipment are you using to send emails?
How big are the emails you tried to send?
Is your email working now?
In which step of gathering symptoms does the network engineer determine if the problem is at the core, distribution, or access layer of the network?
