Dell EMC Exam D-SNC-DY-00 Topic 3 Question 11 Discussion

Actual exam question for Dell EMC's D-SNC-DY-00 exam
Question #: 11
Topic #: 3
[All D-SNC-DY-00 Questions]

Refer to the exhibit.

Eth 1/1 of SONiC-1 and Eth1/56 of SONiC-2 should be a routed link connecting the two Enterprise SONiC switches. No traffic is passing between them.

What is the cause of the failure?

Show Suggested Answer Hide Answer
Suggested Answer: A

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.

A missing cable, eh? That's like trying to play Tetris without any blocks - good luck with that one!

IPv6, huh? That's like the elusive Loch Ness monster of networking - you never know when it's gonna pop up and cause problems. Better check those settings!

Hold up, what if it's a spanning-tree issue? I've seen that trip up even the best network engineers. Gotta check those STP configs.

Hmm, looks like a connection issue. I bet it's the cable - who unplugged it? Probably the intern trying to 'optimize' the network.

Maybe the cable between SONiC-1 and SONiC-2 is unplugged.

But if the cable is unplugged, there won't be any traffic passing between the switches.

I disagree, I believe it's option B, a spanning-tree blocking the link.

I think the cause of the failure is option D, a cable that is unplugged.

Ah, the classic spanning-tree dance. I'll go with option B, just to keep things interesting.

Maybe IPv6 is not enabled on SONiC-1's interface.

I think the issue is with the IPv6 address type on SONiC-2.

C'mon, guys, let's not be IPv6 deniers. I bet it's option C - no IPv6 on that interface.
