AWS Certified Solutions Architect study material · question 160 of 500

Why is running a periodic restore in advance of any disaster considered good practice?

  1. Restoring is a control plane operation that may be unavailable during the disaster
  2. Restored data is billed at a lower rate than backups
  3. It shortens the replication lag of the source data
  4. It converts the backup into a point-in-time snapshot
Show the answer

Answer: A. Restoring is a control plane operation that may be unavailable during the disaster

Because restore depends on the control plane, having already-restored data stores means the workload is not blocked if that control plane is impaired.
