Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
/run/log/journal
Why it's wrong here
journald stores standard system service logs, not raw kernel core crash dumps.
- ✗
/var/lib/kubelet/pods
Why it's wrong here
This directory stores ephemeral pod volumes and container data.
- ✓
/var/crash
Why this is correct
When kdump is enabled on RHCOS, kernel core dumps are saved in /var/crash.

/var/log/audit/audit.log
Why it's wrong here
audit.log records security-related kernel syscalls, not kernel panic memory dumps.
