Two from the bank, answered.

Real items, with the answer marked and the reason written out — the same format as all 22.

Troubleshooting

Which journalctl command shows kernel messages from the current boot only?

  1. Ajournalctl -k -bCorrect
  2. Bjournalctl --disk-usage
  3. Cjournalctl -f
  4. Djournalctl --vacuum-time=1d

Why: 'journalctl -k' limits output to kernel messages (like dmesg) and '-b' limits it to the current boot, so '-k -b' shows this boot's kernel log. '-f' follows new entries, and '--vacuum-time' deletes old journal data rather than displaying it.

System Management

Which directory in the Filesystem Hierarchy Standard is intended to hold variable data such as logs, spool files, and caches?

  1. A/usr
  2. B/opt
  3. C/etc
  4. D/varCorrect

Why: /var stores variable data that changes during normal operation, including /var/log, /var/spool, and /var/cache. /etc holds system configuration, /usr holds read-only user programs and libraries, and /opt holds optional add-on software packages.

Questions

Asked before starting.

Is the practice really free, or does it stop after a few questions?

All 22 questions, the timed mock and the report are free with no sign-up. A free account only adds saving your progress.

Is your mock the same as the real CompTIA Linux+ (XK0-006)?

No. Ours is 22 questions in 90 minutes; the real exam is 90 questions in 90 minutes. Use the mock for stamina and section timing, not as a score predictor.

What score do I need?

720 / 900 — as published by CompTIA. Confirm the current rule with them before your exam date.
