Question 40
After domain isolation deployment, an unmanaged printer cannot reach its spooler and staff need a narrow exemption rather than disabling isolation globally. Which observed result BEST demonstrates that the intended outcome has been achieved?
Explanation
Correct Answer
Eligible domain members establish authenticated traffic where required while untrusted machines cannot silently join the isolated zone. This is an observable acceptance condition, not merely evidence that a feature was enabled. Connection security rules authenticate or protect IP traffic independently of simple port allow rules; endpoints must agree on authentication and policy. Situation: After domain isolation deployment, an unmanaged printer cannot reach its spooler and staff need a narrow exemption rather than disabling isolation globally.
Incorrect Answers
An Azure Windows VM serves only intended ports from approved networks while exposed management ports and unintended bypass paths are blocked. This tests Azure NSG effective rules for Windows Server VMs, but does not demonstrate that the requested outcome is satisfied. The relevant acceptance test is: Eligible domain members establish authenticated traffic where required while untrusted machines cannot silently join the isolated zone. Situation: After domain isolation deployment, an unmanaged printer cannot reach its spooler and staff need a narrow exemption rather than disabling isolation globally.
Selected Windows security events arrive with correct host, event IDs and timestamps and relevant detections work without collecting unnecessary sensitive logs. This tests Microsoft Sentinel Windows security-event ingestion, but does not demonstrate that the requested outcome is satisfied. The relevant acceptance test is: Eligible domain members establish authenticated traffic where required while untrusted machines cannot silently join the isolated zone. Situation: After domain isolation deployment, an unmanaged printer cannot reach its spooler and staff need a narrow exemption rather than disabling isolation globally.
An unsigned test executable is denied under the enforced policy while documented critical workloads and approved updates still start normally. This tests Windows Defender Application Control trust policy, but does not demonstrate that the requested outcome is satisfied. The relevant acceptance test is: Eligible domain members establish authenticated traffic where required while untrusted machines cannot silently join the isolated zone. Situation: After domain isolation deployment, an unmanaged printer cannot reach its spooler and staff need a narrow exemption rather than disabling isolation globally.
