  3. C.Only require MFA at the cloud portal
  4. D.Only encrypt DC backup storage
Show the answer and explanation

✓ Correct answer

  • Require domain-controller LDAP signing after compatibility assessment

LDAP signing protects the stated unsigned traffic boundary. Backup encryption, cloud MFA, and service-password rotation can be useful controls but do not require signatures on the LDAP connection.
