Designing Cisco Enterprise Networks (ENSLD) — Question 2

Which solution allows overlay VNs to communicate with each other in an SD-WAN Architecture?

Answer options

• A. External fusion routers can be used to map VNs to VRFs and selectively route traffic between VRFs.
• B. GRE tunneling can be configured between fabric edges to connect one VN to another.
• C. SGTs can be used to permit traffic from one VN to another.
• D. Route leaking can be used on the fabric border nodes to inject routes from one VN to another.

Correct answer: A

Explanation

The correct answer is A because external fusion routers effectively manage the mapping of VNs to VRFs and control the traffic flow between them. Options B, C, and D are incorrect as they do not provide the same level of selective routing capability between overlay VNs as external fusion routers do.
