You need to deploy Windows 11 to a remote office with limited bandwidth. Which deployment method is most appropriate?
BranchCache caches content locally, reducing WAN usage.
Why this answer
BranchCache is the most appropriate deployment method for a remote office with limited bandwidth because it allows clients to cache content locally from a peer after the first download, reducing WAN link usage. In Windows deployment, BranchCache can be used with Configuration Manager or standalone to distribute OS images efficiently by having clients retrieve data from local peers rather than repeatedly downloading from a central source over a slow link.
Exam trap
The trap here is that candidates often confuse BranchCache with peer caching in general or assume multicast is always the best for bandwidth savings, but multicast still requires a full WAN transfer of the image, whereas BranchCache avoids redundant WAN traffic entirely after the first download.
How to eliminate wrong answers
Option A is wrong because Windows Autopilot is a cloud-based provisioning method that requires internet connectivity to download the OS image from Microsoft Intune or Windows Update, which would consume significant bandwidth over a limited link. Option B is wrong because PXE boot deployment from a local server requires a local Distribution Point or server at the remote site, which may not be available or feasible in a remote office with limited infrastructure. Option D is wrong because multicast deployment from a central location sends a single stream to multiple clients simultaneously, but it still requires the entire OS image to traverse the WAN link once, which can saturate limited bandwidth and does not leverage local caching.
