are shown. Which statement describes what is incorrect about the configuration shown?

Correct:A
7.When using MPLS unicast IP forwarding, what will happen if an LSR receives an incoming
labeled packet but the LSR can’t find that incoming label in its LFIB?
A.The packet will be forwarded using the FIB.
B.The packet will be forwarded using the LIB.
C.The packet will be process switched by performing a route lookup in the routing table.
D.The packet will be forwarded using the LFIB with an impnull
outgoing label.
E.The packet will be dropped even if the IP destination exists in the FIB.
Correct:E
8.Refer to the exhibit. Based on the show outputs, which condition could be preventing the P1
