Cisco Designing Cisco Enterprise Networks Sample Questions (Q41-Q46):

NEW QUESTION # 41
Which design consideration must be made when dual WAN Edge routers are deployed at a branch site?

A. HSRP priorities must match the OMP routing policy to prefer one WAN Edge over the other.
B. Use BGP AS-path prepending to influence egress traffic and use MED to influence ingress traffic from the branch.
C. Configure BFD between WAN Edge routers to detect sub-second link failures.
D. Traffic must be symmetrical as it egresses the WAN Edges and returns from remote sites for DPI to function properly.

Answer: A

Explanation:
When dual WAN Edge routers are deployed at a branch, first-hop redundancy and SD-WAN overlay path preference must be aligned. The correct design consideration is that HSRP priorities on the service side should match the OMP routing policy that determines which WAN Edge is preferred. If the LAN gateway points hosts to one WAN Edge while OMP policy prefers the other edge for return or remote-site traffic, traffic can become asymmetric or hairpinned through the wrong device. Proper alignment gives predictable active/standby or active/active behavior and avoids blackholing during failover. Option A describes traditional BGP path manipulation with AS-path prepending and MED; those are not the primary SD-WAN branch dual-edge design controls. Option C overstates symmetry as a universal requirement for DPI; Cisco SD-WAN can handle many traffic patterns, but gateway and OMP alignment remain the core branch design issue. Option D is wrong because SD-WAN already uses BFD across data-plane tunnels, not as a special direct adjacency between the two local WAN Edges for this purpose. Reference topics: Cisco SD-WAN branch redundancy, HSRP, OMP policy, WAN Edge preference, service-side high availability.
