Question 200
A network access incident review reveals: A laptop installs the missing patch and its agent reports compliant, yet a wired switch keeps enforcing the original remediation ACL until the user reconnects. Which Cisco ISE design or authorization principle accounts for this result?
Explanation
Correct Answer
The underlying principle is: An existing NAD session needs a supported reauthorization or RADIUS CoA to apply the compliant access result after posture state changes. Address this by: Check posture state transitions, CoA destination reachability and NAD session handling so completed assessment triggers approved session update. The confirming operational observation is: Without unplugging the cable a remediated test laptop leaves the restricted ACL and receives the authorized compliant network access.
Incorrect Answers
An earlier compliant result can become stale unless the configured posture lease and periodic reassessment behavior require current state checks. “Configure supported posture reassessment and session policies with tolerances appropriate to the risk and network architecture” would remedy that alternative situation, but it would not correct the present issue: an existing NAD session needs a supported reauthorization or RADIUS CoA to apply the compliant access result after posture state changes.
“Configure the supported agentless posture prerequisites with least-privilege credentials and permitted management paths for eligible endpoints” is the supported response when agentless posture relies on supported remote system access mechanisms and credentials, so network connectivity alone does not yield reliable compliance evidence. Here the decisive response is “Check posture state transitions, CoA destination reachability and NAD session handling so completed assessment triggers approved session update”, so that different intervention does not meet the stated requirement.
Mandatory, Optional, and Audit posture requirements have different enforcement semantics; optional failure need not cause denial of compliant access. “Set the patch check to Mandatory in the intended posture policy and map failed assessment to the approved remediation result” applies to that other condition. The reported evidence is a laptop installs the missing patch and its agent reports compliant, yet a wired switch keeps enforcing the original remediation ACL until the user reconnects; this alternative would address the wrong dependency.
