CompTIA SecurityX (CAS-005) Practice Tests

Ten scenario questions from CompTIA with an answer key at the end but no explanations. A quick look at how CompTIA words a SecurityX question, including log and architecture scenarios.

Great fit if you want to see CompTIA's own question style before spending anything.

Poor fit if you need explanations, PBQs or a full-length run; move on to Training Camp or Dion.

A 50-question timed test on the four CAS-005 domains, with a 25-question quick version. Every answer choice has an explanation, and each retake draws new questions. It asks for your name, email and phone first.

Great fit if you want a free, explained diagnostic across all four domains before buying a full set.

Poor fit if you need PBQs or several full-length exams; it is multiple choice only (see Dion).

Six timed 90-question exams with feedback on each question and results by domain. It is the set passing candidates name most, though they say the real exam's wording is harder and vaguer.

Great fit if you want the main full-length set, with enough exams to sit a timed run and still have fresh ones left.

Poor fit if you need PBQ or Linux-task practice; it is multiple choice, so add labs.

Randomized question sets with answer explanations and unlimited attempts, drawn from a larger bank than Dion's Udemy exams. Each attempt gives a fresh mix of questions.

Great fit if you want a cheap extra source of fresh questions beside the Udemy exams.

Poor fit if you want fixed, numbered full-length exams to track from one sitting to the next; use the Udemy set.

The largest bank here, in short quizzes and mock exams with explanations and progress by subject. Quiz modes include weakest subject and missed questions.

Great fit if you study in short sessions on your phone and want a large bank to drill by domain.

Poor fit if you want a one-time purchase or PBQ practice; use Dion's exams and labs.

A certification mode that holds explanations until the end, and a practice mode where you set the question count and timer, with referenced explanations. A free demo lets you try it first.

Great fit if you want a second, independent bank with referenced explanations and can use the free demo first.

Poor fit if you are on a budget; Dion's $80 exams hold more than twice the questions.

CompTIA's own practice product, with timed practice exams, quizzes by objective and a mastery score for each objective. Candidates say its questions are easier than the real exam's.

Great fit if your employer pays, or you buy CompTIA's exam bundle, where it adds little to the voucher cost.

Poor fit if you would pay $284 alone; Dion's pack costs a tenth as much.
