XDR-Engineer Maintenance And Troubleshooting Practice Question
An administrator is investigating high memory utilization on a Cortex XDR Broker VM deployed in the environment. Which THREE diagnostic steps or log reviews should the administrator perform? (Choose three)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Run 'top' or 'htop' via SSH on the Broker VM to identify which specific processes are consuming excessive memory.
Broker VM troubleshooting involves checking system resource consumption, container/service status, and collector log outputs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Recompile the Linux kernel on the Broker VM appliance to optimize memory paging.
Why it's wrong here
Recompiling the kernel is neither supported nor necessary for Broker VM maintenance.
- ✓
Run 'top' or 'htop' via SSH on the Broker VM to identify which specific processes are consuming excessive memory.
Why this is correct
Standard Linux process monitoring utilities identify resource-heavy processes on the Broker VM appliance.
- ✓
Review the Broker VM system health metrics under Settings > Configurations > Broker VM in the console.
Why this is correct
The management console provides centralized health monitoring and resource statistics for deployed Broker VMs.
- ✓
Inspect collector logs under /var/log/pan/ for potential event loops or memory leaks during high ingestion spikes.
Why this is correct
Collector logs record parsing errors and queue bottlenecks that can lead to memory exhaustion.
- ✗
Change the Broker VM disk partition table using fdisk.
Why it's wrong here
Modifying partition tables on a running virtual appliance risks corrupting the image and is not a troubleshooting step for memory usage.
