You are asked to reduce the load that the JIMS server places on your Which action should you take in this situation?

The question implies a need to reduce the operational load that the Juniper Identity Management Service (JIMS) places on its primary data source, the Domain Controllers (DCs). JIMS's default method of polling DC event logs for user-to-IP address mappings can be resource-intensive. To mitigate this, JIMS can be configured to use alternative data sources. Connecting JIMS to a RADIUS server allows it to collect user-to-IP mappings directly from RADIUS accounting reports. This is a highly efficient and direct method for obtaining identity information at the point of network access (e.g., 802.1X or VPN), thereby reducing or eliminating the need to poll the DCs and lowering their processing load.

B. Connect JIMS to the domain Exchange server: While JIMS can use Exchange server logs as a data source, RADIUS accounting is a more direct and purpose-built mechanism for tracking user-to-IP network sessions, making it a more precise solution.

C. Connect JIMS to the domain SQL server: JIMS does not use a domain SQL server as a data source to acquire user-to-IP address mappings. JIMS uses its own local SQL database for storage.

D. Connect JIMS to another SRX Series device: SRX Series devices are consumers (clients) of the identity information provided by the JIMS server. Connecting another SRX device would increase the load on the JIMS server, not reduce it.

JIMS Configuration Guide

"Understanding JIMS" Section. This guide details the architecture and data sources for JIMS. It explicitly lists "RADIUS Accounting" as a supported data source alongside "Event Log" and "Microsoft Exchange Server." The guide states

"JIMS can also be configured to collect user identity information from RADIUS accounting servers." This confirms that using RADIUS is a valid method to acquire identity information

which offloads the Domain Controllers.

"Configuring Data Sources" Section. This section provides configuration details for each data source. The presence of a dedicated configuration chapter for RADIUS Accounting confirms it as an officially supported method to provide user identity data to JIMS

which serves the goal of reducing reliance on DC event log polling. The guide explains how to "Configure JIMS to collect user identity information from RADIUS accounting servers."
