Question NO:01
Refer to the exhibit. Which three statements about MPLS LDP operations are true?

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