Which three statements about MPLS LDP operations are true?
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.
