   A company is designing SD-WAN for a campus with 5,000 users and 20 remote branches. The campus has a high-capacity MPLS link, and branches have broadband. The design must ensure that the campus can handle the aggregate traffic from all branches and that a single branch's traffic spike does not degrade the campus experience. Which design consideration is most important?

   • AUse the campus edge as a backup only and route all branch traffic directly to the internet
   • BConfigure QoS on the campus edge to prioritize all branch traffic over campus traffic
   • CSize the campus edge device and MPLS link to handle the aggregate branch traffic with sufficient headroom
   • DDeploy a full mesh overlay so branches do not route through the campus

   A multinational company is deploying SD-WAN across 500 sites. The network team wants to define a single security policy for all branch firewalls and push it automatically, while also allowing regional administrators to view local traffic statistics. Which architectural component should be used to achieve this centralized management model?

   • AA dedicated management VLAN at each site with a local policy server
   • BAn on-premises firewall manager at headquarters that pushes policies via site-to-site VPN
   • CA central SD-WAN controller that hosts the policy and distributes it to all edge devices
   • DA gateway at each regional hub that replicates policies to its local branches

   A bank is designing SD-WAN for 200 branches. The design must ensure high availability for branch connectivity. Each branch has two edge devices, and the bank wants to avoid a single point of failure at the branch. The SD-WAN controller is hosted in a public cloud. Which design decision best meets the high-availability requirement?

   • ADeploy two edge devices at each branch in an active/standby pair, with both connected to the controller
   • BDeploy a single edge device at each branch and rely on the underlay for failover
   • CDeploy a single edge device at each branch with dual WAN uplinks
   • DDeploy two controllers in different cloud regions

   Which statement correctly describes the relationship between underlay and overlay networks in SD-WAN?

   • AThe underlay provides physical connectivity, while the overlay provides logical connectivity over it.
   • BThe overlay is the physical infrastructure, and the underlay is the logical tunnels.
   • CThe overlay is used only for internet traffic, while the underlay is used for MPLS.
   • DThe underlay and overlay are the same thing in SD-WAN.

   In SD-WAN, what is the primary role of the overlay network?

   • ATo provide the physical transport links (e.g., MPLS, broadband) between sites
   • BTo provide only security encryption between sites
   • CTo replace the need for any physical connectivity
   • DTo create a logical, virtualized network on top of the physical transport
