   A logistics company operates branches in rural areas where only LTE is available, and headquarters has MPLS and broadband. The SD-WAN design must provide connectivity for these LTE-only branches while maintaining secure communication. Which approach should the architect take?

   • ARequire the branches to install a second broadband circuit before joining the SD-WAN
   • BUse LTE as the sole underlay transport for those branches and establish secure overlay tunnels to headquarters
   • CConnect the branches via a traditional site-to-site VPN without SD-WAN
   • DUse the LTE link as a backup only and rely on dial-up for primary connectivity

   A company with 30 branches is migrating from a hub-and-spoke MPLS WAN to SD-WAN. The branches have MPLS and broadband. The migration must be completed within a 6-month window, and the company cannot afford a full-mesh overlay due to the number of tunnels and edge device processing overhead. Which deployment model best balances migration speed, cost, and performance?

   • AFull-mesh SD-WAN overlay with direct tunnels between all 30 branches
   • BPartial-mesh overlay connecting only branches with high traffic, with others on MPLS
   • CHub-and-spoke SD-WAN overlay with the headquarters as the hub, using broadband as a secondary transport
   • DKeep the existing MPLS hub-and-spoke and add SD-WAN only at headquarters

   A financial services firm uses SD-WAN to connect its branches. VoIP traffic must have low latency and jitter, while email and file transfers are less sensitive. The firm has MPLS and broadband links at each site. The SD-WAN must automatically select the best path for each application based on real-time link conditions. Which feature should be configured?

   • AEqual-cost multipath (ECMP) across MPLS and broadband for all traffic
   • BPolicy-based routing based on source IP address of VoIP phones
   • CStatic routing that sends VoIP to MPLS and all other traffic to broadband
   • DApplication-aware routing with SLA monitoring to steer VoIP to the path meeting latency and jitter thresholds

   A global company with 1,000 branches is deploying SD-WAN. The network team is small and wants to minimize operational overhead. The company requires that new branch sites be brought online with minimal manual configuration. Which SD-WAN feature should be leveraged to achieve this?

   • AZero-touch provisioning (ZTP) where the edge device automatically connects to the controller and downloads its configuration
   • BUsing the underlay provider to configure the edge devices
   • CManual configuration of each edge device via CLI before shipping to the branch
   • DA dedicated network engineer at each branch to configure the device

   What is a primary advantage of centralized policy management in SD-WAN?

   • APolicies are stored only on the edge devices and not centrally.
   • BPolicies are only applied during initial deployment and cannot be changed.
   • CPolicies must be configured individually on each edge device.
   • DPolicies are created once and automatically deployed to all relevant devices.
