   A regional bank is deploying SD-WAN to 45 branch offices. Each branch runs a mix of point-of-sale systems, IP phones, and a local file server. The bank expects branch traffic to grow 20% annually over the next three years. The IT director wants to standardize on a single device model for all branches to simplify training and spare-part inventory. Which device selection approach best meets the bank's requirements?

   • AChoose a mid-range device that comfortably handles the largest branch's current traffic and accept that smaller branches are over-provisioned.
   • BSelect the highest-throughput device in the vendor's catalog to ensure all branches have ample headroom for future growth.
   • CDeploy two device tiers: a high-end model for large branches and a low-end model for small branches, accepting the added inventory complexity.
   • DSelect a device model that meets the largest branch's projected three-year traffic, then use it for all branches to maintain standardization.
