Question 220
A network operations team wants to disable NTLM tomorrow although several finance applications still authenticate to legacy SMB services. Which observed result BEST demonstrates that the intended outcome has been achieved?
Explanation
Correct Answer
Approved Kerberos authentication succeeds on designated hosts while disallowed NTLM or privileged sign-ins are logged and rejected under the tested policy. This is an observable acceptance condition, not merely evidence that a feature was enabled. A domain-wide NTLM disable without usage discovery can break legacy systems; authentication policy silos narrow where sensitive accounts may authenticate. Situation: A network operations team wants to disable NTLM tomorrow although several finance applications still authenticate to legacy SMB services.
Incorrect Answers
A controlled suspicious identity pattern produces attributable alerts while normal authentication remains available and sensor health is verified. This tests Defender for Identity domain controller signals, but does not demonstrate that the requested outcome is satisfied. The relevant acceptance test is: Approved Kerberos authentication succeeds on designated hosts while disallowed NTLM or privileged sign-ins are logged and rejected under the tested policy. Situation: A network operations team wants to disable NTLM tomorrow although several finance applications still authenticate to legacy SMB services.
Only authorized branch users can authenticate during a temporary WAN disruption and privileged domain passwords are not stored on the RODC. This tests RODC password replication policy in branch offices, but does not demonstrate that the requested outcome is satisfied. The relevant acceptance test is: Approved Kerberos authentication succeeds on designated hosts while disallowed NTLM or privileged sign-ins are logged and rejected under the tested policy. Situation: A network operations team wants to disable NTLM tomorrow although several finance applications still authenticate to legacy SMB services.
A stolen disk remains encrypted at rest and an authorized recovery operator can unlock the intended volume using a protected and recorded recovery process. This tests BitLocker recovery and protector escrow, but does not demonstrate that the requested outcome is satisfied. The relevant acceptance test is: Approved Kerberos authentication succeeds on designated hosts while disallowed NTLM or privileged sign-ins are logged and rejected under the tested policy. Situation: A network operations team wants to disable NTLM tomorrow although several finance applications still authenticate to legacy SMB services.
