Select all that apply. Every correct option and no extras are required for credit in the app.

  1. A.Assume the newest recovery point cannot contain attacker persistence
  2. B.Validate recovered systems in a controlled environment before reconnecting them
  3. C.Grant production administrators permanent rights to delete recovery data
  4. D.Validate required retention and operating behavior before irreversible locking
  5. E.Treat locked immutability as a substitute for all recovery drills
Show the answer and explanation

✓ Correct answers

  • Validate recovered systems in a controlled environment before reconnecting them
  • Validate required retention and operating behavior before irreversible locking

Validate required retention and operating behavior before irreversible locking: Locking cannot be undone, so the supported workload and retention design must be correct. Validate recovered systems in a controlled environment before reconnecting them: Recovery should confirm trusted operation rather than restore into ongoing compromise. Grant production administrators permanent rights to delete recovery data: Shared destructive authority undermines ransomware resilience. Assume the newest recovery point cannot contain attacker persistence: Recent backups can contain malicious changes and require validation. Treat locked immutability as a substitute for all recovery drills: Protected storage does not prove usable data, dependencies, or restoration time.
