Dell EMC Exam D-SNC-DY-00 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.

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?

Hmm, I'm not sure. Is it possible to just skip this question and move on? I need to find the answer key hidden in the vending machine.
