Which option allows the Endpoint Security Management Server to modify client settings such as shutting...

Push Operationsallow the Endpoint Security Management Server to modify client settings, such as shutting down or restarting computers, without requiring a policy installation. This is detailed on page 69 under "Performing Push Operations," where the guide states that administrators can perform immediate actions like "Restart Computer" and "Shutdown Computer" on selected clients. Options like Remote Operations (A) and Node Management (B) are not documented features for this purpose, while Remote Help (C) is intended for user assistance, such as password recovery (page 425), not direct client modifications.
