Q161. - (Topic 5)
A network administrator enters the following command on a router: logging trap 3. What are three message types that will be sent to the Syslog server? (Choose three.)
The Message Logging is divided into 8 levels as listed below:
Level Keyword Description 0
emergencies System is unusable 1
Immediate action is needed 2
Critical conditions exist 3
Error conditions exist 4
Warning conditions exist 5
Normal, but significant, conditions exist 6
informational Informational messages 7
debugging Debugging messages
If you specify a level with the “logging trap level” command, that level and all the higher levels will be logged. For example, by using the “logging trap 3 command, all the logging of emergencies, alerts, critical, and errors, will be logged.
Q162. - (Topic 8)

Enhanced Interior Gateway Routing Protocol (EIGRP) summary route 5
External Border Gateway Protocol (BGP) 20
Internal EIGRP 90
IGRP 100 OSPF 110
Intermediate System-to-Intermediate System (IS-IS) 115

Q163. - (Topic 8)
Which command can you enter to troubleshoot the failure of address assignments?
A. show ip dhcp pool
B. show ip dhcp database
C. show ip dhcp import
D. clear ip dhcp server statistics
Q164. - (Topic 8)
Which NAT function can map multiple inside addresses to a single outside address?
Q165. - (Topic 7)
What are three reasons to collect Netflow data on a company network? (Choose three.)
A. To identify applications causing congestion.
B. To authorize user network access.
C. To report and alert link up / down instances.
D. To diagnose slow network performance, bandwidth hogs, and bandwidth utilization.
E. To detect suboptimal routing in the network.
F. To confirm the appropriate amount of bandwidth that has been allocated to each Class of Service.
NetFlow facilitates solutions to many common problems encountered by IT professionals.
+ Analyze new applications and their network impact
Identify new application network loads such as VoIP or remote site additions.
+ Reduction in peak WAN traffic
Use NetFlow statistics to measure WAN traffic improvement from application-policy changes; understand who is utilizing the network and the network top talkers.
+ Troubleshooting and understanding network pain points
Diagnose slow network performance, bandwidth hogs and bandwidth utilization quickly with command line interface or reporting tools. -> D is correct.
+ Detection of unauthorized WAN traffic
Avoid costly upgrades by identifying the applications causing congestion. -> A is correct.
+ Security and anomaly detection
NetFlow can be used for anomaly detection and worm diagnosis along with applications such as Cisco CS-Mars.
+ Validation of QoS parameters
Confirm that appropriate bandwidth has been allocated to each Class of Service (CoS) and that no CoS is over- or under-subscribed.-> F is correct.
Q166. - (Topic 8)
Which three circumstances can cause a GRE tunnel to be in an up/down state? (Choose three.)
A. The tunnel interface IP address is misconfigured.
B. The tunnel interface is down.
C. A valid route to the destination address is missing from the routing table.
D. The tunnel address is routed through the tunnel itself.
E. The ISP is blocking the traffic.
F. An ACL is blocking the outbound traffic.
Q167. - (Topic 8)
Which statement about switch access ports is true?
A. They drop packets with 802.1Q tags.
B. A VLAN must be assigned to an access port before it is created.
C. They can receive traffic from more than one VLAN with no voice support
D. By default, they carry traffic for VLAN 10.
"If an access port receives a packet with an 802.1Q tag in the header other than the access VLAN value, that port drops the packet without learning its MAC source address."
Q168. - (Topic 3)
Which command would you configure globally on a Cisco router that would allow you to view directly connected Cisco devices?
A. enable cdp
B. cdp enable
C. cdp run
D. run cdp
CDP is enabled on Cisco routers by default. If you prefer not to use the CDP capability, disable it with the no cdp run command. In order to reenable CDP, use the cdp run command in global configuration mode. The “cdp enable” command is an interface command, not global.
