Explanation

This question requires identifying two operations that would fail specifically when only an Azure Blob Storage legal hold is active and all time-based retention policies have expired, given that AllowProtectedAppendWrites was enabled for the time-based policies.

Common mistakes.

  • A. Overwriting existing documents would fail under an active time-based retention policy (even with AllowProtectedAppendWrites enabled, as it applies to appends, not overwrites), meaning it does not fail only when a legal hold is in effect.
  • C. Deleting documents would fail under an active time-based retention policy, meaning it does not fail only when a legal hold is in effect.
