   A company is deploying SD-WAN between its headquarters and a branch. The traffic will traverse the public internet. The design requires that all intersite traffic be encrypted and that the overlay be resilient to transport failures. Which tunneling approach should the SD-WAN design use?

   • AIPsec tunnels over each transport link
   • BA single IPsec tunnel over the primary link only
   • CPlain GRE tunnels without encryption
   • DMPLS VPN only, without any overlay

   A branch has three transports: MPLS (50 Mbps, low latency), broadband (200 Mbps, high latency), and LTE (20 Mbps, variable latency). The branch runs a critical ERP application that needs low latency and a video-conferencing application that needs consistent bandwidth. The SD-WAN must use all three transports to maximize capacity. Which transport strategy should the design use?

   • ASteer ERP to MPLS, video to broadband, and use LTE for best-effort traffic
   • BSteer all traffic to broadband because it has the highest bandwidth
   • CSteer all traffic to MPLS because it has the lowest latency
   • DUse LTE for ERP because it is a dedicated cellular link

   An SD-WAN edge has two transports: MPLS with 10 ms latency and 0.1% loss, and broadband with 40 ms latency and 1% loss. The site runs a VoIP application that requires latency below 30 ms and loss below 0.5%. The MPLS link is currently congested with a large file transfer. The SD-WAN policy is configured for application-aware routing. What should the SD-WAN edge do to maintain VoIP quality?

   • ADrop the file transfer entirely to free MPLS capacity for VoIP
   • BSteer VoIP to MPLS and the file transfer to broadband, because MPLS meets the VoIP requirements
   • CSteer VoIP to broadband because it has higher bandwidth
   • DKeep the file transfer on MPLS and send VoIP to broadband to avoid congestion

   How does segmentation enhance security in SD-WAN intersite connectivity?

   • ABy isolating different types of traffic to prevent lateral movement
   • BBy using a single routing table for all sites
   • CBy encrypting all traffic with a single key
   • DBy blocking all traffic from the internet

   A retail chain has 200 branch sites that each connect to two regional data centers. The branches primarily access centralized applications hosted in the data centers, and only a few branches exchange data directly with each other. The design team wants to minimize the number of tunnels while ensuring that all branch-to-branch traffic can still flow. Which intersite connectivity model should the team choose?

   • AHub-and-spoke
   • BPoint-to-point dedicated circuits
   • CPartial mesh with direct branch-to-branch tunnels
   • DFull mesh
