ClearPass will send the Session-Timeout attribute in the RADIUS Access-Accept packet to the User and the user's session will be terminated after 600 seconds.

Answer(s): E

Explanation:

Session Timeout (in seconds) - Configure the agent session timeout interval to re-evaluate the system health again. OnGuard triggers auto-remediation using this value to enable or disable AV-RTP status check on endpoint. Agent re-authentication is determined based on session-time out value. You can specify the session timeout interval from 60 600 seconds. Setting the lower value for session timeout interval results numerous authentication requests in Access Tracker page. The default value is 0.
