Dell EMC Exam D-SNC-DY-00 Topic 1 Question 13 Discussion

Actual exam question for Dell EMC's D-SNC-DY-00 exam
Question #: 13
Topic #: 1
[All D-SNC-DY-00 Questions]

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?

Show Suggested Answer Hide 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'd go with C. Efficient communication across the VXLAN fabric is where it's at. Plus, who doesn't love a little 'EVPN' in their life?
