Answers
C.
IPv6 is not enabled on interface Eth 1/1 of SONiC-1.
D.
There is a cable that is unplugged between SONiC-1 and SONiC-2.
Answers
D.
There is a cable that is unplugged between SONiC-1 and SONiC-2.
Suggested answer: A

Explanation:

From the exhibit, it is evident that Eth1/56 on SONiC-2 is assigned a link-local IPv6 address (fe80::e7d:8aff:fecb

/64). Link-local addresses are not routable beyond the local network segment, which means they cannot be used to route traffic between SONiC-1 and SONiC-2. For routed links, global unicast addresses must be used.
