A. interface Fa0/1 ip address 192.168.10.1 255.255.255.0 ! interface Fa0/2 ip address 192.168.20.1 255.255.255.0 ! 

B. interface Fa0/1 ip address 192.168.10.1 255.255.255.0 ! interface Fa0/2 ip address 192.168.20.1 255.255.255.0 !

Answer: C 

Q4. Refer to the exhibit. 

***Exhibit is Missing*** 

Which three statements about MPLS LDP operations are true? (Choose three.) 

A. The incoming label for 10.2.10.1/32 is 16010 (which is allocated by the local router), and the outgoing label is 22 (as advertised by the next-hop router). 

B. The 16003 and 16010 labels are learned from the 192.168.112.40 LDP neighbor. 

C. The ImpNull outgoing label for the 192.168.102.0/24 network means that the outgoing label should be removed when sending packets to the 192.168.112.40 next-hop router, when the incoming label is 16003. 

D. The ImpNull outgoing label for the 192.168.102.0/24 network means that the local router has not received a label for that network from its neighbor. 

E. The Unlabeled outgoing label for 10.10.10.100/32 indicates that a label pop is required when sending packets to the 10.10.10.1 next-hop router. 

F. The outgoing label of 22 for 10.2.10.1/32 is learned from the 192.168.112.40 LDP neighbor. 

Answer: A,C,F 

Q5. On Cisco IOS XR software, which two of the address-family command options in IS-IS configuration mode are valid? (Choose two)

D. address-family vpnv4 

E. address-family vpnv6 

Answer: B,C 

Q6. Which three statements about access control lists on a Cisco IOS router are true? (Choose three) 

A. The more specific ACL entries should be placed at the top of the ACL. 

B. The generic ACL entries should be placed at the top of the ACL, to filter general traffic and reduce noise on the network. 

C. ACLs always search for the most specific entry before taking any filtering action. 

D. Router-generated packets cannot be filtered by the interface ACLs on the router. 

E. Extended ACLs should be placed as close to the destination as possible. 

F. There must be at least one permit statement in an ACL, or all traffic is denied. 

Answer: A,D,F 

Q7. Which file extension indicates a bootable installation file in Cisco IOS XR software?

B. .tar 

C. .smu 

D. .pie 

E. .vm 

F. .mini 

Answer: E 

Q8. You have just enabled IS-IS on the lab testing network. You notice that IS-IS is not using the optimal path selection based on the interface bandwidth. Currently, the IS-IS routing process seems to be selecting the best path based on the hop count. 

What configuration change can you make to cause IS-IS to select the optimal path based on the interface bandwidth? 

A. Enable a wide-style IS-IS metric. 

B. Enable a narrow-style IS-IS metric. 

C. Change the default auto-cost reference bandwidth to a higher value. 

D. Change the default IS-IS metric on each of the router interfaces to better correspond to the interface bandwidth. 

E. Change the interface bandwidth by using the bandwidth interface configuration mode command. 

Answer: D 

Q9. Which two statements about NAT444 are true? (Choose two.)

C. NAT444 needs to work together with DNS64. 

D. There are two types of NAT444 (stateful or stateless). 

E. NAT is performed by the CPE and also by the service provider router. 

Answer: B,E
