Practice question 132 of 498 · hard

An organization needs resilient cloud authentication while retaining on-premises identity synchronization. Which two statements are correct? Select two.

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

  1. A.Synchronized identities cannot be affected by source-directory compromise
  2. B.PHS removes every on-premises security responsibility
  3. C.Synchronization infrastructure must still be protected and recoverable
  4. D.A single PTA agent provides equivalent dependency reduction
  5. E.PHS can remove the live on-premises password-validation dependency
Show the answer and explanation

✓ Correct answers

  • Synchronization infrastructure must still be protected and recoverable
  • PHS can remove the live on-premises password-validation dependency

Cloud password validation can use PHS while synchronization remains critical. PHS does not remove source-directory responsibilities; PTA retains live dependency, and compromised source identities can still affect hybrid security.
