Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 405

How is replicator information relayed to the WAN Edge router in an SD-WAN multicast environment?

Answer options

• A. The replicator sends its information directly to all PIM-enabled WAN Edge routers in the same VPN as the replicator.
• B. The administrator enters the replicator IP address under the multicast configuration of the WAN Edge router.
• C. The replicator sends an OMP multicast-autodiscover route to vSmart, which forwards the information to the WAN Edge router.
• D. The WAN Edge router broadcasts a multicast-auto discover message to vBond.

Correct answer: C

Explanation

The correct answer is C because the replicator uses an OMP multicast-autodiscover route to communicate with vSmart, which is responsible for relaying the information to the WAN Edge router. Option A is incorrect as it describes direct transmission to WAN Edge routers, while Option B is not valid since manual entry of the IP address is not how the replicator operates. Option D is also wrong because the WAN Edge router does not send a multicast-auto discover message to vBond for this purpose.
