AWS Certified Solutions Architect study material · question 167 of 500

Why do many teams keep failover initiation manual while automating every step behind it?

  1. AWS requires a support case before failing over
  2. A false alarm costs the same availability and data loss that a real failover does
  3. Automated failover is not supported by Route 53
  4. Manual failover completes faster than automated failover
Show the answer

Answer: B. A false alarm costs the same availability and data loss that a real failover does

Recovery time and recovery point are never zero, so failing over unnecessarily incurs real loss; the steps are automated but the decision stays human.
