_______________________________________________________________

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.

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

_______________________________________________________________

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.
_______________________________________________________________
