What can trigger the inactive Agent cleanup to delete an Agent?

The correct answer is based on the operational parameters set within the Trend Micro Deep Security system concerning agent management. The inactive Agent cleanup is specifically designed to monitor the activity levels of agents connected to the Deep Security Manager. When an agent goes beyond a defined period of inactivity—meaning it has not communicated with the server or completed assigned tasks—the cleanup process is triggered to automatically remove these inactive agents. This helps maintain an efficient and manageable environment by ensuring that obsolete or unresponsive agents do not clutter the management dashboard or consume unnecessary resources.

The active monitoring of agent status is critical for the performance and security of the system, ensuring that only currently functioning and useful agents remain in the system. Other considerations, such as manual deletions or resource issues, do not initiate the automated cleanup process directly related to inactivity. Additionally, while lack of updates may create vulnerabilities or inefficiencies, it is not a direct trigger for the cleanup functionality related to the inactivity of agents. Thus, understanding the focus on activity levels is key to grasping why defined periods of inactivity are the trigger for agent cleanup.
