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

Actual exam question for Dell EMC's Dell SONiC Deploy Exam exam

Question #: 11
Topic #: 3

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?

AAn incorrect IPv6 address type was used for interface Eth1/56 of SONiC-2.

BA spanning-tree is blocking the routed link.

CIPv6 is not enabled on interface Eth 1/1 of SONiC-1.

DThere is a cable that is unplugged between SONiC-1 and SONiC-2.

Show Suggested 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.

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.

User1: 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.

Hmm, I think it's option D. That cable must be as elusive as the Loch Ness Monster!

User4: I agree with User1, it's probably the unplugged cable, option D.
