CompTIA CySA+ (CS0-004) Practice Tests

Validates knowledge of security operations, including alert and log analysis, vulnerability prioritization, incident handling and reporting.

CySA+ CS0-004 is up to 85 questions in 165 minutes: multiple choice plus performance-based questions (PBQs). The scenario questions are built on logs, scan output and incident steps, and PBQs have you read several systems and reach a conclusion. We compared the main options on log-heavy questions, PBQ coverage and price.

Start with CompTIA's free 10-question sample and Training Camp's free 50-question test, then add Dion's exam pack or the Sybex practice-test book for volume.

Free first look

CySA+ Practice Test (V4)

Ten multiple-choice questions from CompTIA with an answer key at the end but no explanations, so you see the exam's own wording before spending anything. It has no performance-based questions.

Great fit if you want CompTIA's question style as a free first check before you study.

Poor fit if you need volume, explanations or a timed run; use Training Camp's free test or Dion.

Free timed sample

Free CySA+ Practice Test (CS0-004)

A 25- or 50-question test across all four domains with a 90-minute timer and an explanation for every answer. New questions appear on each retake. Training Camp sells boot camps and follows up by email.

Great fit if you want a free, timed diagnostic with explanations before you buy a paid set.

Poor fit if you do not want to give an email address, or you need more than one sitting's worth of questions; use CompTIA's sample or Pocket Prep's 40 free questions.

Timed full exams

CompTIA CySA+ (CS0-004) Practice Exam Pack

Randomized full-length practice exams with unlimited attempts and explanations of why answers are right or wrong. It is the practice set CS0-004 passers name most often.

Great fit if you want low-cost, timed full exams that you can retake with fresh question sets.

Poor fit if you want realistic PBQs or a large published question count; add the Sybex book for log-heavy questions.

Log-heavy questions

CompTIA CySA+ Practice Tests: Exam CS0-004, 4th Edition

Questions grouped by CS0-004 domain, two full practice exams and explanations, with the Sybex online test bank. Candidates call it difficult and rich in log-reading questions, the skill the exam leans on.

Great fit if you want hard, log-based questions and a domain-by-domain workbook you can finish in a week or two.

Poor fit if you want timed, auto-scored exams on a phone; use Dion or Pocket Prep.

Study on your phone

CySA+ CS0-004 Question Bank

Short quizzes, timed mock exams and a weakest-subject mode in a phone and web app, with scores by domain. Candidates find the questions a little easier than Sybex's.

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

Poor fit if you want hard log scenarios or PBQ practice; use the Sybex book.

Objective drills

CertMaster Practice for CySA+ (CS0-004)

CompTIA's own timed and untimed practice tests with objective quizzes and a mastery score for each exam objective. Candidate opinion is split: some find the wording vague, others passed using it.

Great fit if your school or employer provides it, or you are buying a voucher anyway: the Practice and Exam Bundle with Retake costs $593 against $579 for the voucher with retake alone.

Poor fit if you would pay $209 on its own; Dion's pack costs $30 and Sybex's book $27.

What to look for in a CySA+ practice test

Match the exam code. CS0-004 launched on June 23, 2026 and allows up to 85 questions in 165 minutes. The English CS0-003 exam retires on December 22, 2026, so buy sets that name CS0-004. Dion's site still sells a CS0-003 pack beside the new one, and some Udemy sets reuse CS0-003 questions.
Look for log, scan and SIEM output questions. Candidates who passed CS0-004 say reading logs was the skill that mattered most, in both the multiple-choice questions and the PBQs. Sybex's book is the set they praise for log-based questions.
Treat PBQs as a separate need. Candidates report between 3 and 8 PBQs, where you open tools and logs from several systems and draw conclusions. No CS0-004 practice set reproduces them, so pair a question bank with free log-analysis labs.
Check you get scores by domain. The domains carry 34%, 26%, 24% and 16% of the exam (Security Operations, Vulnerability Management, Incident Response, Reporting). Pocket Prep and CertMaster Practice show scores by subject or objective, which shows where to study.
Read the explanations on offer. CompTIA's free sample gives only an answer key. Training Camp, Dion and Sybex explain answers, and a wrong-answer explanation helps most on look-alike options.
Skip sites selling "real exam questions." Sites promising actual CS0-004 questions or a guaranteed pass are selling leaked or copied items. CompTIA's candidate agreement counts using brain dumps as misconduct and lets CompTIA revoke every CompTIA certification you hold. A real practice test explains why each answer is right; a dump only lists answers.

How to use CySA+ practice tests

Take one test cold as a diagnostic. Use CompTIA's 10 questions or Training Camp's 50 before you study heavily, then read the explanations for the questions you got right as well as wrong.
Log misses by domain and topic. Note each miss against its domain and objective, then restudy it. Candidates repeatedly say CVSS scoring, MITRE ATT&CK, the Cyber Kill Chain and the Diamond Model came up.
Practise reading logs outside the question bank. Practice questions teach the shape of an answer. Candidates preparing for the PBQs recommend free SOC and SIEM labs such as TryHackMe's blue-team rooms.
Run full timed exams late, and do PBQs last. In the final weeks sit 85-question, 165-minute runs. Several candidates flagged the PBQs, answered the multiple-choice questions first and returned to the PBQs at the end.
Use scores to find gaps, not to predict the result. Passers report practice scores from 71% to 91% across Dion, Pocket Prep and CertMaster. Do not retake a test until you have forgotten the answers.

CySA+ practice test FAQ

Are there free CySA+ practice tests?

Yes. CompTIA publishes 10 free CS0-004 questions with an answer key, Training Camp offers a free 50-question timed test with explanations (name and email required), and Pocket Prep gives 40 questions free. Use the V4 page, because CompTIA's V3 page is for the retiring exam.

Are CySA+ practice tests harder than the real exam?

Reports are mixed. Candidates call Sybex's book difficult and say the real exam felt easier, rate Pocket Prep slightly easier than Sybex, and split on CertMaster. The harder parts of the real exam they name are log analysis and the PBQs.

Do CySA+ practice tests include PBQs?

Mostly not in a form that matches the exam. The sets here are mainly multiple choice, and candidates say no resource mimics the PBQs. Prepare by practising log and SIEM analysis in free labs.

Can I use CS0-003 practice tests for CS0-004?

Only as extra practice. CS0-004 adds topics such as AI in security operations and reweights the domains, and candidates who sat both versions call V4 more practical. If you test on CS0-003, you must do so by December 22, 2026.
