***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 

Q8. Refer to the exhibit. 

***Exhibit is Missing*** 

Which statement is true? 

A. VLAN 1 traffic is sent untagged on the fa0/11 trunk port. 

B. All VLANs traffic, including the native VLAN traffic, is tagged with a VLAN ID when it is sent over the fa0/11 trunk port. 

C. The switchport trunk allowed vlan command is not configured; therefore, no VLANs are allowed on the trunk. 

D. The encapsulation type that is used is 802.1ad. 

E. The switchport trunk native vlan command is not configured; therefore, the trunk is not operational. 

Answer: A
