A logistics company requires Windows laptops to pass a disk-encryption check before reaching the file share. Laptops missing the compliance agent must be steered to a download page, the agent then reports its result, and the live session must pick up the new policy without waiting for the next periodic reauthentication. Which posture workflow sequence applies?
Select an answer to reveal the explanation.
Short Explanation
You can think of posture as a three-beat loop: an authorization rule redirects a non-compliant laptop to the portal, the agent reports its result, and ISE sends a change of authorization so the live session can use updated policy. Group-policy deployment skips the required redirect, while waiting for a timer or a new 802.1X session delays the update or omits CoA.
Full Explanation
The posture workflow begins with an authorization rule that redirects a laptop failing the disk-encryption requirement to the ISE posture portal, keeping the file share unavailable until the requirement is met. The portal offers the agent for download; after installation, the agent checks disk encryption and reports its result to ISE. ISE then sends a change of authorization (CoA) to the network access device, prompting the live session to be re-evaluated so ISE can apply the compliant authorization without waiting for periodic reauthentication. CoA updates authorization sooner, but it does not guarantee that the user experiences no interruption. Deploying the agent by group policy at first login may install it, but it does not perform the required authorization-rule redirect to the portal. Holding the laptop until the next reauthentication timer delays applying the reported result. Waiting for a new 802.1X session without CoA also omits the specified mechanism for updating the live session. Exam caveat: the redirect can use an access list, a URL, or both, depending on the platform and configuration. Practical check: review ISE operations and the network access device session details to confirm the CoA and updated authorization result.
