External Endpoint Policy Servers (EPS) are optional components in the Harmony Endpoint architecture, designed to enhance performance in large or geographically distributed environments. Their primary function is to offload tasks from the Endpoint Security Management Server (EMS) and optimize network resource usage across sites. TheCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfprovides a clear description of this role.
Onpage 25, under the section "Optional Endpoint Security Elements," the documentation states:
"Endpoint Policy Servers improve performance in large environments by managing most communication with the Endpoint Security clients. Managing the Endpoint Security client communication decreases the load on the Endpoint Security Management Server, and reduces the bandwidth required between sites. The Endpoint Policy Server handles heartbeat and synchronization requests, Policy downloads, Anti-Malware updates, and Endpoint Security client logs."
This extract explicitly confirms that EPS:
Decrease the load on the EMS: By taking over client communication tasks (e.g., policy downloads, heartbeat requests, and log uploads), EPS reduce the processing burden on the central EMS.
Reduce the bandwidth required between sites: In distributed environments, clients connect to a local EPS rather than a distant EMS, minimizing the data transfer across site boundaries.
Option Daccurately reflects this dual role, making it the correct answer. Let’s evaluate the other options for clarity:
Option A ("Decrease policies and reduce traffic between sites"): EPS do not decrease the number of policies; policies are still defined and managed by the EMS. While "reduce traffic" could loosely align with bandwidth reduction, it lacks the specificity of "load on the EMS," making it incomplete.
Option B ("Decrease power and reduce accidents between sites"): This is irrelevant to endpoint security, as "power" and "accidents" are not concepts addressed in the context of EPS functionality.
Option C ("Decrease clients and reduce device agents between sites"): EPS do not reduce the number of clients or agents; they manage existing clients more efficiently, so this option is incorrect.
Thus,Option Dis the only choice fully supported by the documentation, providing a precise and complete description of EPS functionality.
