The XK0-005 exam, officially titled CompTIA Linux+ Certification Exam, is the CompTIA exam you pass to earn the CompTIA Linux+ certification, a credential at the Professional level. Passing it confirms the skills defined in the official exam outline, and it is associated with related credentials such as CompTIA A+, CompTIA Network+, CompTIA Server+.

The XK0-005 exam includes Up to 90 questions and gives you 90 minutes to finish them. That is a tight pace per question, so get used to reading each stem once, flagging anything uncertain, and moving on rather than getting stuck. Running timed practice tests in the Fast2test desktop or online test engine is the most reliable way to build that rhythm before exam day.

The passing score for the XK0-005 exam is 720 (scale 100–900), and the official registration fee is $348 USD. Keep in mind that a failed attempt means paying $348 USD again in full to retake it, so book your slot only when your scores on Fast2test practice tests sit consistently above the passing line.
