XDR-Engineer Planning And Installation Practice Question
An administrator is deploying the Cortex XDR agent in a Linux environment and encounters dependency issues during the RPM installation. Specifically, the system reports missing kernel headers. What is the impact on Cortex XDR functionality if kernel headers or required kernel development packages are missing?
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
✓
The agent installation will fail or certain kernel-dependent prevention and monitoring modules will not load properly
Certain Linux preventive and behavioral monitoring features rely on kernel modules that require matching kernel headers/devel packages to compile successfully during installation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The endpoint will experience an immediate kernel panic and enter a reboot loop
Why it's wrong here
Missing headers cause installation or module loading failures, not kernel panics.
- ✗
The agent will automatically download the correct kernel source code from the public Linux kernel archives
Why it's wrong here
The agent does not automatically download kernel source code from external repositories during installation.
- ✓
The agent installation will fail or certain kernel-dependent prevention and monitoring modules will not load properly
Why this is correct
Linux kernel-level monitoring requires compiling or loading kernel modules, which fail if required headers/dependencies are absent.
- ✗
The agent will operate normally without any functional limitations because Linux does not use kernel modules for security
Why it's wrong here
Linux agents rely heavily on kernel components and modules for deep visibility and protection.
