XK0-006 Practice Question: Match each Linux kernel parameter category to its…
Match each Linux kernel parameter category to its description.
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
✓
kernel: General kernel behavior and system-wide limits
Linux sysctl parameters are organized under categories such as kernel, vm, net, and fs. The kernel category handles general system limits, vm manages virtual memory, net controls networking, and fs deals with filesystem settings. Ensure each description matches its correct category.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
kernel: General kernel behavior and system-wide limits
Why this is correct
The 'kernel' sysctl category controls core kernel features such as hostname, max processes, and security settings.
- ✓
vm: Virtual memory and swap management
Why this is correct
The 'vm' category includes parameters for memory pages, swap space, and OOM handling.
- ✓
net: Networking configuration and tuning
Why this is correct
The 'net' category covers IP, TCP, UDP, and other networking stack parameters.
- ✓
fs: Filesystem quotas and inode management
Why this is correct
The 'fs' category includes filesystem-specific settings like inode max values and quota enforcement.
- ✗
vm: Networking parameters
Why it's wrong here
Incorrect — networking parameters belong to the 'net' category, not 'vm'.
- ✗
kernel: Filesystem parameters
Why it's wrong here
Incorrect — filesystem parameters belong to the 'fs' category, not 'kernel'.
