XK0-005 Question #793: Real Exam Question with Answer & Explanation

The correct answer is B: /proc/7991/oom_score. To find the Out-Of-Memory (OOM) score for a specific process with PID 7991, the engineer should look for the oom_score file within the process's directory in the /proc filesystem. The /proc filesystem provides an interface to kernel data structures and process information.

Question

A Linux engineer needs to determine the oom_score value for PID 7991. Which of the following files should the engineer verify to find this value?

Options

A/var/7991/oom_score
B/proc/7991/oom_score
C/opt/7991/oom_score
D/usr/config/7991/oom_score

Explanation

To find the Out-Of-Memory (OOM) score for a specific process with PID 7991, the engineer should look for the oom_score file within the process's directory in the /proc filesystem. The /proc filesystem provides an interface to kernel data structures and process information.

Common mistakes.

A. /var is typically used for variable data like logs and spool files, not for process-specific kernel information.
C. /opt is traditionally used for optional or third-party software packages, not for dynamic kernel or process data.
D. /usr/config is not a standard location for process-specific OOM information in Linux; /usr typically contains read-only user programs and libraries.

Concept tested. Linux /proc filesystem, OOM killer, process information
