Q16 Container Registry Domain 1 · 20–25% of exam Priority · Real Exam

An image built for linux/amd64 fails to run on an ARM-based Container App. What is the correct fix in ACR Tasks?

  1. A Enable geo-replication to an ARM region
  2. B Build a multi-architecture image with --platform linux/arm64 and publish a manifest list (correct answer)
  3. C Re-tag the existing image as arm64
  4. D Disable Content Trust

Shortcut: Architecture is baked into the image. ACR Tasks can build per-platform images and combine them into a manifest list, so a single tag resolves to the right architecture at pull time.
