   A university with multiple campuses uses a traditional WAN where all inter-campus traffic is routed over a single MPLS link. The network team wants to implement SD-WAN to use both MPLS and broadband internet links. What is a key difference in traffic handling between the traditional WAN and the SD-WAN that the team should understand?

   • ATraditional WAN requires a controller, while SD-WAN can be managed without one.
   • BTraditional WAN uses a single path for all traffic, while SD-WAN can use multiple paths simultaneously and select the best one per application.
   • CTraditional WAN encrypts all traffic by default, while SD-WAN requires separate encryption configuration.
   • DTraditional WAN automatically fails over to a backup link, while SD-WAN requires manual intervention.
