Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reformat the Linux root filesystem and reinstall the operating system kernel.
Why it's wrong here
Reformatting the system is a destructive and unnecessary troubleshooting step.
- ✓
Verify that required kernel headers or dependencies are installed and loaded properly.
Why this is correct
Linux kernel modules and dependencies are critical for agent operation and driver hooks.
- ✓
Inspect agent log files located in the designated log directory (e.g., /var/log/traps or /var/log/cortex).
Why this is correct
Linux agent logs are stored in standard system log paths for review.
- ✗
Modify the Windows Registry keys for the Cortex XDR service.
Why it's wrong here
Linux does not use the Windows Registry.
- ✓
Check the agent service status using systemctl (e.g., `systemctl status cxdr` or legacy service daemon names).
Why this is correct
Systemctl is used to verify service health on modern Linux distributions.
