External Policy Servers are placed between the Endpoint clients and the Endpoint Security Management Server.

External Endpoint Policy Servers (EPS) are optional components in Harmony Endpoint’s architecture, designed to enhance scalability and performance by offloading client communication tasks from the Endpoint Security Management Server (EMS). TheCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfexplicitly outlines their benefits.

Onpage 25, under "Optional Endpoint Security Elements," the guide states:

"The Endpoint Policy Server handles heartbeat and synchronization requests, Policy downloads, Anti-Malware updates, and Endpoint Security client logs."

This extract confirms that a primary benefit of the EPS is managingheartbeat and synchronization requests. Heartbeat requests are periodic signals from clients to report status and connectivity, while synchronization ensures clients remain aligned with server policies and updates. By handling these, the EPS reduces the load on the EMS and optimizes bandwidth, directly supportingOption B.

Let’s assess the other options:

Option A: Cluster and Delta requests– "Cluster" is unrelated to EPS functionality (it may pertain to HA), and "Delta requests" is not a defined term in the guide.

Option C: Test packet and delta requests– "Test packet" is not mentioned in the documentation, and "delta requests" lacks context, making this incorrect.

Option D: Polling beat and delta requests– "Polling beat" is not a recognized term (likely a misnomer for heartbeat), and "delta requests" is unsupported by the text.

Option Bis the only choice directly supported by the documentation, accurately reflecting the EPS’s role in improving communication efficiency.
