AZ104-Q: recover an overwritten blob

An application overwrites a configuration blob. Administrators need to restore the previous content without restoring the whole account. What should have been enabled?

  • A) A resource lock on the storage account.
  • B) Blob versioning, then make the prior version current or copy it to a new blob. ✓
  • C) A longer SAS expiry.
  • D) A file-share snapshot. Answer: B. Blob versioning retains prior versions that can be restored or copied. Why not the others: Locks and SAS do not preserve content; Azure Files snapshots apply to file shares.
