Validates knowledge of Linux system management, services and users, security, automation and scripting, and troubleshooting.
Linux+ XK0-006 is up to 90 questions in 90 minutes: multiple choice plus performance-based questions (PBQs). The questions are short scenarios about commands, scripts and terminal output, and PBQs have you complete a task such as restoring an LVM volume. We compared the main options on PBQ coverage, volume and price.
Start with CompTIA's free 10-question sample, then add Dion's six timed exams and Pocket Prep's larger bank, and rerun every miss in a Linux virtual machine.

Ten questions straight from CompTIA, including command-output scenarios and a select-two item, with an answer key but no explanations. It has no PBQs, so it shows the wording but not the simulations.
Great fit if you want to see CompTIA's own question style on V8 topics before you spend anything.
Poor fit if you need volume, explanations or a timed full run; use Dion or Pocket Prep.
Six timed 90-question exams mixing multiple choice and PBQ-style items, with a score report by domain. Candidate reports say they run easier than the real exam, so they test coverage and pacing more than readiness.
Great fit if you want several full, timed exams with domain scores at a very low price.
Poor fit if you want a hard final check or a real PBQ simulation; add Pocket Prep and practise tasks in a virtual machine.
Quizzes and mock exams in an app and in the browser, with explanations, results by subject and a weakest-subject mode for targeted drilling. It has the largest bank of the paid options.
Great fit if you study in short sessions and want a large bank to drill by subject.
Poor fit if you want a one-time purchase or PBQ practice; use Dion's exams and a virtual machine.
A practice mode with hints and explanations and an exam mode with no help, filterable by objective. It is a small bank for the price and has no mobile app.
Great fit if you want a second, low-cost source of objective-by-objective questions to use after Dion's exams.
Poor fit if you study on your phone or want a bigger bank; use Pocket Prep.
CompTIA's own practice tool with timed practice tests, objective quizzes and a mastery score for each exam objective. It costs several times what the third-party sets do.
Great fit if your employer or school provides it, or you buy CompTIA's $548 exam bundle, where it adds $29 to the voucher with retake.
Poor fit if you would pay $209 on its own; Dion and Pocket Prep cost far less.

Yes. CompTIA publishes 10 free V8 questions with an answer key and no explanations, and Pocket Prep gives 30 free questions. Many other free Linux+ sets were written for the retired XK0-005, so check the exam code.
Candidate reports say Dion's exams are easier than the real exam, and Linux+ is widely described as one of CompTIA's harder exams. Use practice tests to find weak domains, and expect the real exam to test commands and output more deeply.
There is no official number. One full-length set plus a larger question bank is enough for most candidates, and the remaining time is better spent running commands in a virtual machine and reviewing every miss.
Dion's Udemy exams say they include PBQ-style items, while CompTIA's free sample has none. Candidates say the real PBQs are harder than practice versions, so rehearse the tasks in a virtual machine.
