   A startup is designing its first WAN. The company has 5 offices and expects to grow to 50 offices in 3 years. The current traffic is low, but the company plans to deploy a new video conferencing application that will require 5 Mbps per office. The budget is limited, but the company wants to avoid re-architecting the WAN as it grows. Which design best balances current cost and future scalability?

   • ADeploy a partial mesh with 50 Mbps links between major offices only
   • BDeploy a hub-and-spoke topology with 10 Mbps links now
   • CDeploy an SD-WAN solution with broadband links and centralized management
   • DDeploy a full mesh topology with 100 Mbps links now

   A regional bank operates 40 branch offices that each connect to one of two regional data centers. Each branch primarily accesses applications hosted in its assigned data center, but must be able to reach the other data center if the primary one fails. The bank wants to minimize the number of WAN circuits while ensuring that a single data center failure does not isolate any branch. Which topology should the design use?

   • AFull mesh between all 40 branches and both data centers
   • BHub-and-spoke with each branch connecting only to its assigned data center
   • CPartial mesh connecting only the two data centers to each other
   • DDual hub-and-spoke with each branch connecting to both data centers
