A Reset operation in Deep Security Manager (applied to an agent) removes all configuration and relationship data from the agent, including its activation status, policy assignments, and communication settings. This essentially returns the agent to an “unmanaged” state, so it must be reactivated and reconfigured before resuming protection.
From the official documentation:
“Performing a Reset operation on an agent removes the agent’s registration and all local settings, effectively deactivating it from the Deep Security Manager. This is useful if you need to re-register the agent with a different manager, or if there are persistent communication or configuration issues.”
Option A is incorrect: Although logs may be generated, the main purpose is to sever the relationship and clear settings, not to generate troubleshooting events.
Option B is incorrect: Reset does not force a software update.
Option C is incorrect: Reset is more than a service restart; it erases the agent’s configuration and registration.
