CySA+ Practice Exams
Build a timed practice exam from 200 original CySA+ (CS0-003) questions. Choose the length, difficulty, and domains, then review explanations and a score report that shows where to study next.
Before you start: These are original practice questions, not CompTIA exam items. They follow CS0-003 objectives version 4.0 (CySA+ V3). English CS0-003 retires on December 22, 2026. CS0-004 is CySA+ V4. CompTIA publishes a passing score of 750 on a scale of 100 to 900, but not the conversion, so the scaled score on this page is unofficial. Everything runs in your browser, and nothing is saved, so print or save your score report before you close the page. For background on each topic, see the core notes and flashcards.

How these practice exams work
Each exam is drawn at random from the questions that match your settings. Questions are spread across the domains you select in proportion to the pool, so a 20-question exam mirrors the weight of each domain instead of clustering in one area. Every attempt draws a new set, and answer choices are shuffled unless you turn that option off.
- Choose your settings. Pick the domains and difficulty levels to include, the number of questions, and a time limit.
- Answer like a timed exam. Move freely between questions, flag questions to revisit, and use the navigator to find anything you skipped. In Exam mode, the exam submits automatically when time runs out.
- Review your score report. See your overall score, results by domain, difficulty, and question type, the explanation for every question, and advice on which topics to study next.
The pool includes multiple-choice, multiple-response, and simple performance-based tasks such as matching a tool to its job and putting a response in order. This page is not a hands-on lab simulator.
Question pool by domain
The 200 questions follow the published CS0-003 domain weights. Security operations, the largest domain, has the most questions.
| Domain | Exam weight | Questions | Beginner / Intermediate / Advanced |
|---|---|---|---|
| 1.0 Security Operations | 33% | 66 | 17 / 31 / 18 |
| 2.0 Vulnerability Management | 30% | 60 | 16 / 28 / 16 |
| 3.0 Incident Response and Management | 20% | 40 | 10 / 19 / 11 |
| 4.0 Reporting and Communication | 17% | 34 | 9 / 16 / 9 |
Difficulty levels: Beginner questions check a single fact, such as what beaconing looks like. Intermediate questions apply a concept to a short scenario. Advanced questions combine several facts, ask for the FIRST or BEST action, or are performance-based tasks.
How scoring works
- Multiple choice and multiple response: one point when every selected answer is correct and nothing extra is selected. There is no partial credit.
- Matching and ordering tasks: partial credit for each item placed correctly.
- Unanswered questions score zero. Answer everything before time runs out.
- Estimated scaled score: your percentage converted linearly to the 100-900 scale and compared with the passing score of 750. CompTIA does not publish its conversion, so treat this only as a way to track your own progress.
In the score report, domains below 75% are marked as focus areas and ordered by impact: a low score in a heavily weighted domain comes first. Aim for 85% or higher across every domain before you move on.
Frequently asked questions
Are these real CompTIA CySA+ exam questions?
No. Every question is original and written from the public CS0-003 objectives, version 4.0. Certicab does not use or distribute leaked exam content, sometimes called brain dumps, which violates the CompTIA candidate agreement.
Does the estimated scaled score predict my real result?
No. CompTIA publishes a passing score of 750 on a scale of 100 to 900, but it does not publish how raw scores convert to that scale. The estimate is a linear guide for comparing your own attempts.
How many practice questions should I answer before booking the exam?
Aim for consistent results around an estimated 750 or higher, and about 85 percent, on mixed-difficulty timed exams that cover every domain. Then review every explanation, including questions you answered correctly.
Are my answers saved or sent anywhere?
No. The exam runs entirely in your browser. Answers and results are not stored or sent, so they disappear when you close or reload the page. Print or save the score report if you want to keep it.
