Question 130
A network operations team wants to disable NTLM tomorrow although several finance applications still authenticate to legacy SMB services. Which administrative configuration or response BEST addresses the primary requirement?
Explanation
Correct Answer
Inventory NTLM authentication paths and privilege-tier boundaries, enforce authentication policy silos for supported high-value accounts, and phase out unsafe NTLM dependencies after testing. This response targets the system boundary described in the case. A domain-wide NTLM disable without usage discovery can break legacy systems; authentication policy silos narrow where sensitive accounts may authenticate. Before applying it, verify: Review domain controller NTLM audit logs, service account SPNs, Kerberos ticket paths, authentication policy assignments, client OS compatibility, and privileged login locations. Situation: A network operations team wants to disable NTLM tomorrow although several finance applications still authenticate to legacy SMB services.
Incorrect Answers
Encrypt supported Windows Server volumes with managed BitLocker protectors, escrow recovery information, and test safe recovery procedures before changing boot configuration. This would address BitLocker recovery and protector escrow, not the controlling issue in this situation. BitLocker protects local volume data at rest; loss of the TPM state or recovery material can make legitimate restoration impossible. The targeted response is: Inventory NTLM authentication paths and privilege-tier boundaries, enforce authentication policy silos for supported high-value accounts, and phase out unsafe NTLM dependencies after testing. Situation: A network operations team wants to disable NTLM tomorrow although several finance applications still authenticate to legacy SMB services.
Configure a Read-Only Domain Controller with an explicit Password Replication Policy permitting only approved branch identities and denying privileged account caching; plan credential exposure response. This would address RODC password replication policy in branch offices, not the controlling issue in this situation. RODCs reduce the sensitive write surface in unsecured sites, but a permissive cached-credential policy can undermine that goal. The targeted response is: Inventory NTLM authentication paths and privilege-tier boundaries, enforce authentication policy silos for supported high-value accounts, and phase out unsafe NTLM dependencies after testing. Situation: A network operations team wants to disable NTLM tomorrow although several finance applications still authenticate to legacy SMB services.
Connect the appropriate Windows security events to a Microsoft Sentinel-enabled Log Analytics workspace using supported collection mechanisms and validated data collection rules. This would address Microsoft Sentinel Windows security-event ingestion, not the controlling issue in this situation. A Sentinel workspace alone does not ingest on-premises server logs; collection rules and healthy agents establish the signal path. The targeted response is: Inventory NTLM authentication paths and privilege-tier boundaries, enforce authentication policy silos for supported high-value accounts, and phase out unsafe NTLM dependencies after testing. Situation: A network operations team wants to disable NTLM tomorrow although several finance applications still authenticate to legacy SMB services.
