Choose the single best answer.

  1. A.Federation signing keys no longer matter
  2. B.PHS guarantees automatic instantaneous fallback in every deployment
  3. C.On-premises compromise cannot affect synchronized users
  4. D.The alternate credential capability alone does not demonstrate operational recovery
Show the answer and explanation

✓ Correct answer

  • The alternate credential capability alone does not demonstrate operational recovery

Recovery requires planned and tested operation. Enabling PHS is not proof of universal automatic fallback; federation keys remain critical and synchronized hybrid identities remain security-sensitive.
