Course Description

All questions are based on the Exam Objectives for the CompTIA CySA+ (CS0-003) exam for all 4 domains of the exam, so you can take and pass the actual CompTIA CySA+ (CS0-003) certification exam with confidence! 

In this course, I fully prepare you for what it is like to take the CompTIA CySA+ (CS0-003) certification exam. These 6 full-length practice exams with 90 questions are timed for 165 minutes to help you pace yourself for the real exam. I have carefully hand-crafted each question to put you to the test and prepare you to pass the certification exam with confidence.


You won't be hoping you are ready, you will know you are ready to sit for and pass the exam. After practicing these tests and scoring an 90% or higher on them, you will be ready to PASS on the first attempt and avoid costly re-schedule fees, saving you time and money.

You will receive your total final score, along with feedback on each and every question, telling you exactly why each answer is correct, and which domain (and objective) you need to study more in order to pinpoint the areas in which you need to improve and perform some additional study. 


This course is designed to help prepare you for the CompTIA CySA+ (CS0-003) certification exam and covers all four domains of the CompTIA CySA+ (CS0-003) certification exam:

  1. Security Operations (33%)

  2. Vulnerability Management (30%)

  3. Incident Response Management (20%)

  4. Reporting and Communication (17%)


Our CompTIA CySA+ (CS0-003) practice exams provide you with realistic test questions and provide you with interactive, question-level feedback. 

I have some of the highest-rated CompTIA training courses on the Udemy platform and I invite you to visit my instructor profile to learn more about me, the certifications that I hold, and read the reviews of my courses. This course is consistently updated to ensure it stays current and up-to-date with the latest release of the CompTIA CySA+ exam, and also provides a 30-day money-back guarantee, no questions asked!

What others are saying about my CompTIA practice exam courses:

  • The questions were tough and it took me about 3 times for each test to reach 100%. I hope they are like the test... Really hope. Great training resources because the explanations are very useful. (Rick, 5 stars)

  • Great tests that provide something close to the scenario-based questions that the exam will show (it's hard as Udemy's platform isn't designed to allow them properly) Diverse questions. Really good explanations. Great learning tool for passing the test as the exams cover a lot off! (Aimee, 5 stars)

  • This course of practice exams has some good concept reinforcing questions and does a good job of rotating/varying the types of questions asked. Highly recommend if preparing for the certification exam. (Matthew, 5 stars)

  • These questions are unique and well-conducted to prepare for the exam with relevant information. I am using multiple resources and this is definitely one to have. (Valdrin, 5 stars)


    Upon completion of this course, you will earn 6 CEUs towards the renewal of your CompTIA A+, Network+, Security+, Linux+, Cloud+, PenTest+, CySA+, or CASP+ certifications.

The course was great for preparing my mind for question expectations. It was overly intense with unnecessary knowledge to know, which makes learning difficult. Though, I could see how it kept the testing environment skill-based. I would recommend giving half points for the BEST answer choices where some answers are almost identical (e.g. DevSecOps is the correct answer not Agile - which uses DevSecOps).

By George Stavroulakis on 6/14/2026

Very nice set of questions, really diverse and covering the material. A lot of things to cover. Sometimes the question is an extreme use case, but it is good to get used to such a possiblity

By Geoffrey Langenberg on 5/14/2026

These test push you to aim high so that when you take the actual exam you feel you really understand the subject matter instead of a surface level Q&A. Just like in the actual exam, it pays to slow down and try to really understand what each question is asking of you. Thanks to these practice quizzes alongside dion training's full CySA+ course, I felt prepared when going in, and passed on my first attempt.

By Colin M on 4/28/2026

If the real exam is similar to some of these questions, it would be incredibly ambigious. Some of the explanations to questions are incredibly poor and there is a lack of true correlation between the question, the answer, and the supposed module of training. It would be much nicer if there was a way to consolidate the mistakes you are making to help refine your revision areas.

By Stevens E on 4/6/2026

I passed. I was getting 70% on these exams and therefore I knew i had the knowledge down pack. Dion's test are always much harder than the actual exam. I destroyed the CYSA with 890. My advice for the new guys. Pay attention to why you got the answers wrong. Know why wrong answers are the wrong answers in detail. If not, lol well don't be surprised if you fail.

By Karen Moss on 4/1/2026

Always love Dion Training videos. Got the package on March 27th, 2026 and aced the CysA+ first sitting on March 29th, 2026. Never worked in Tech! Thank you Dion Training!

By Yves de Carvalho Carabajal on 3/24/2026

As questões são boas mas acredito ser no nível da prova da CompTIA Security Plus. Não tenho certeza se o formato dessas questões tem haver com a realidade da prova oficial.

By Aaron Scales on 2/20/2026

I highly recommend these practice exams to anyone preparing for certification. The questions are expertly designed and mirror the exact style of the CompTIA exam, making them invaluable for effective study. Thanks to these practice exams, I passed on my first try! I've consistently utilized practice tests in my study routine, and they have played a crucial role in my success across all the certifications I've pursued. Don’t underestimate the power of practice—these exams can make all the difference in your preparation!

By Elkwood Boltfire on 1/28/2026

Just came back from passing my CySA+ test. This materiel really helped! Having (6) 90 questions practice test to go thru sharpen up my thinking skills for the test nicely. Went through each test multi times except for the 6th. Did it just once. Thanks !

By João Rafael Avansini Baião on 9/26/2025

It really helps you to prepare for the CYSA+ exam; the mocks are harder than the actual exam, so if you manage to get a score between 60 and 70, you are in good shape for the real exam.
