Cortex XDR agents on Linux consist of several services that handle different aspects of agent functionality, such as event collection, policy enforcement, and health monitoring.Memory monitoringfor agent health involves tracking the memory usage of the agent’s core processes to ensure they are operating within acceptable limits, which is critical for maintaining agent stability and performance. Thepmd(Process Monitoring Daemon) service is responsible for monitoring the agent’s health, including memory usage, on Linux systems.

Correct Answer Analysis (D):Thepmdservice should be monitored to fulfill the request for memory monitoring. The Process Monitoring Daemon tracks the Cortex XDR agent’s resource usage, including memory consumption, and reports health metrics to the console. Monitoring this service ensures the agent remains healthy and can detect issues like memory leaks or excessive resource usage.

Why not the other options?

A. dypdng: This is not a valid Cortex XDR service on Linux. It appears to be a typo or a misnamed service.

B. clad: The clad service (Cortex Linux Agent Daemon) is responsible for core agent operations, such as communication with the Cortex XDR tenant, but it is not specifically focused on memory monitoring for health purposes.

C. pyxd: The pyxd service handles Python-based components of the agent, such asscript execution for certain detections, but it is not responsible for memory monitoring or agent health.

Exact Extract or Reference:

TheCortex XDR Documentation Portalexplains Linux agent services: “The pmd (Process Monitoring Daemon) service on Linux monitors agent health, including memory usage, to ensure stable operation” (paraphrased from the Linux Agent Deployment section). TheEDU-260: Cortex XDR Prevention and Deploymentcourse covers Linux agent setup, stating that “pmd is the service to monitor for agent health, including memory usage, on Linux systems” (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes “planning and installation” as a key exam topic, encompassing Linux agent deployment and monitoring.
