Exam-day tips for XK0-006
- 1Know real commands and options — PBQs can ask you to pick or order commands, not just define them.
- 2Practice on an actual Linux VM: LVM, fstab, systemctl/journalctl, firewalld/ufw/iptables/nftables, and SELinux/AppArmor.
- 3Understand file permissions and special bits (setuid, setgid, sticky) and how umask affects new files.
- 4Read short bash and Python snippets and predict their output; version-control questions focus on core Git workflows.
- 5For troubleshooting, follow logs and metrics first (journalctl, dmesg, top, iostat, ss) before changing configuration.
