CompTIA Linux+ (XK0-006) practice exam: 750 questions on the V8 objectives, 261 command-line items. 40 free XK0-006 practice exam questions.
750 practice questions for CompTIA Linux+ XK0-006, covering the V8 objectives including the new Python, version control and AI material. Every question carries a worked explanation.CompTIA Linux+ XK0-006 practice exam is the V8 revision of CompTIA's Linux administration certification, and it replaced XK0-005 for English candidates in January 2026. It is a vendor-neutral exam: it expects you to know the pieces every distribution has, and to recognize the equivalent command whether you are sitting in front of a Red Hat family server or a Debian family one. This bank holds 750 questions written against the V8 objectives, split across the five domains in the same proportion CompTIA publishes them.
Linux+ asks what you would do at a prompt on a server that is already broken, and the wrong preparation for it is a list of commands. Knowing that a command exists does not tell you why a filesystem turned read only on its own, why a service answers locally and refuses every remote client, or why a process ignores every signal you send it. The questions here are written about the way the work actually arrives: a symptom, some evidence, and a decision about which layer to look at next. Many of them hand you four readings and ask which resource is constrained, or four commands that differ by a single flag and ask which one does the job described.
Every question carries a worked explanation that argues the reasoning rather than restating the winning option, and it accounts for the wrong answers as well, because most of them are true in a different situation. That is the part that turns a practice attempt into study: you find out why the answer you picked was reasonable, and exactly where it stops being right. No explanation in this bank repeats its own answer back at you.
CompTIA leans on performance-based items harder in V8 than it did before, and candidates consistently report them as the hardest part of the paper. This bank includes drag-and-drop questions that ask you to place things rather than pick one: sorting evidence by the layer it implicates, matching a tool to the question it settles, grouping settings by the scope they apply to. It also includes command questions where the four options are real command lines, and where the difference between them is often one flag or one letter of case. Reading those carefully is the skill the terminal items reward, and it is not a skill anybody builds by reading prose about commands.
Exam Coach AI sits next to the question while you work. Ask it what an inode is, why your disk is full when the free space report says otherwise, when to use a systemd timer instead of cron, or what steal time means on a virtual machine, and it answers in plain language. It will not hand you the answer to the question in front of you, deliberately: it is there for the moment you are stuck on a concept rather than stuck between two options. It also handles ordinary questions, such as what to study first and how the marking works, so you are not leaving the exam to look something up.
If you studied XK0-005, the domain you have not seen is Automation, Orchestration and Scripting. V8 added Python, version control and the responsible use of AI assistants to it, and none of those existed before. The domain is named almost the same way it was, so it is easy to assume the material is familiar and arrives under-prepared on roughly a sixth of the paper. That is the single most useful thing to check before you book. If you are also working toward Security+, the Security domain here overlaps directly with the host hardening, access control and cryptography material in our CompTIA Security+ SY0-701 practice exam, and the two banks are written to the same standard, so the study time carries across.
The pass mark is 70% of the questions you answer correctly, marked as a plain percentage, so the number on your result page is the number that matters. Each sitting draws 90 questions from the pool of 750, in the same domain proportions as the exam:
The result breaks down by domain rather than giving you a single figure, which is what makes a 68% useful: it tells you which domain to go back to instead of leaving you to guess. Because every sitting is drawn from a much larger pool, retaking it puts a genuinely different paper in front of you.
40 questions are free, and they span all five domains weighted the way the paid pool is, so the preview is a fair sample rather than a selection of the easy ones. That is enough to see how the explanations are written, meet a drag-and-drop board and a command question, and decide whether this is the right material for you before you pay for anything.
