Question: 1/50
An enterprise is redesigning its WAN edge to support multiple transports (MPLS and Internet) while keeping branch complexity low. The requirement is to steer voice over the most predictable path and bulk traffic over the cheapest available path, with fast convergence during brownouts. Which design approach best meets these goals?
Deploy SD-WAN with centralized policy and application-aware routing across transports
Deploy static route tracking with IP SLA at each branch and use PBR for voice
Use eBGP to both providers and rely on local-preference with AS-path prepending
Use OSPF over GRE tunnels to all sites with ECMP and DSCP-based queuing
