Practice question 230 of 400 · medium

An Azure Files application must tolerate a zone outage and survive interrupted file sessions. What should be included?

Choose the single best answer.

  1. A.RA-GRS assumed to provide a normal readable Files secondary share
  2. B.LRS only, relying on client retries to replace zone copies
  3. C.A storage key rotation as a guarantee no file session is ever interrupted
  4. D.A compatible ZRS share plus reconnect behavior and sufficient surviving application/share performance
Show the answer and explanation

✓ Correct answer

  • A compatible ZRS share plus reconnect behavior and sufficient surviving application/share performance

Supported ZRS covers the zone boundary while clients/performance support real service continuity. Retries cannot add missing copies, Files secondary access differs from Blob, and key rotation does not guarantee session continuity. Source guide: PDF page 41-42.
