Dell EMC D-SNC-DY-00 Exam - Topic 1 Question 7 Discussion

Actual exam question for Dell EMC's D-SNC-DY-00 exam

Question #: 7
Topic #: 1

Enterprise SONiC Switch 1 and Switch 2 are part of a symmetric VXLAN fabric in a data center environment. Switch 1 has learned MAC addresses from its local VLANs.

What role does BGP EVPN play in this scenario?

ADistributes locally learned MAC addresses to Switch 2

BEstablishes Layer 2 connectivity between Switch 1 and Switch 2

CEnables efficient communication across the VXLAN fabric

Show Suggested Answer

Suggested Answer: A

BGP EVPN (Border Gateway Protocol Ethernet VPN) is used in a VXLAN fabric to distribute MAC address reachability information between switches. In this scenario, Switch 1 uses BGP EVPN to advertise the locally learned MAC addresses to Switch 2. This distribution of MAC addresses enables the switches to build and maintain an efficient forwarding table, facilitating communication across the VXLAN fabric.

I'm a bit confused; I thought BGP EVPN was more about MAC address distribution, so A seems right, but I also see how C could fit.

I remember something about BGP EVPN helping with Layer 2 connectivity, but it might also have a role in communication efficiency. Could it be B?

I think BGP EVPN is mainly about distributing MAC addresses, so maybe it's A? But I'm not completely sure.

The key here is understanding how BGP EVPN enables efficient communication across the VXLAN fabric. It's not just about establishing Layer 2 connectivity, but also optimizing the data plane for traffic forwarding. I think option C is the way to go.

Hmm, I'm a bit unsure about this one. I know BGP EVPN has something to do with VXLAN, but I'm not sure exactly how it works in this scenario. I'll have to think it through carefully.

Okay, let's see. Since Switch 1 has learned MAC addresses from its local VLANs, BGP EVPN must be responsible for distributing those MAC addresses to Switch 2. That's got to be the right answer.

I'm a bit confused by this question. I know Truffle is an Ethereum development tool, but I can't recall the exact details of what it's used for. I'll have to eliminate the options I'm sure are wrong, then make an educated guess between the remaining choices.

It's hard to say for sure, but agreeing with the witness might just escalate things further. I would lean towards reasoning with them instead.

B is the way to go! Establishing Layer 2 connectivity between the switches is the key function of BGP EVPN in this scenario. Who needs MAC addresses when you have pure, unadulterated connectivity?
