CompTIA SecurityX (CAS-005) Practice Test
Free CAS-005 practice tests for senior-level security architecture and engineering. Each test has 20 questions on a roughly 37-minute clock, keeping the pace close to the 165-minute SecurityX exam. No account or sign-up required.
Mixed-set SecurityX practice tests
Five 20-question sets spread practice across all four CAS-005 domains. Security Engineering has the largest official weight at 31%, so it deserves the most attention when you review a weak result.
Domain-wise SecurityX practice tests
Once a mixed set exposes the gap, isolate it. Each of these tests stays inside one CAS-005 domain so you can work on the decision patterns that keep costing you questions.
Twenty questions finds the gap.
Ninety questions tests whether your pacing survives it.
The free sets are built for diagnosis. The full-length tests use 90 questions and the full 165-minute practice window, with the same four-domain allocation across all ten papers.
| Free tests | Full-length tests | |
|---|---|---|
| Questions | 20 | 90 |
| Time limit | ~37 minutes | 165 minutes |
| Coverage | Mixed set or one domain | All four domains in one paper |
| Domain allocation | Focused diagnosis | 18 / 24 / 28 / 20 questions |
| Number available | 9 | 10 |

How to use these tests
Use the short sets to find the problem. Save the long ones for the point when you need to know whether your decisions still hold up two hours into the clock.
Benchmark
Take two mixed sets before you start patching individual topics. Look for a repeated weak domain rather than reacting to one missed question.
Start with Practice Test 1 →Drill the gap
Move to the matching domain test. SecurityX questions are usually decided by one constraint, so review why the losing option fails in that scenario.
Practice Security Engineering →Dress rehearsal
Then sit a complete 90-question test under the 165-minute clock. No stopping halfway. The point is to expose hesitation before exam day.

SecurityX is CompTIA's expert-level security certification for experienced practitioners working across architecture, engineering and enterprise security operations.
SecurityX replaced the CASP+ name
CompTIA launched SecurityX on 17 December 2024 as part of its Xpert Series. The current exam is CAS-005. Its objectives focus on architecting and engineering secure solutions across complex cloud, on-premises and hybrid environments, while still testing governance, risk, operations and emerging security concerns.
The older CAS-004 exam retired on 17 June 2025. If your study material still centres on CAS-004, check it against the current CAS-005 objectives before using it as your main source.
Exam format
Exam code: CAS-005.
Questions: Maximum of 90.
Duration: 165 minutes.
Question types: Multiple-choice and performance-based.
Result: Pass/fail only. CompTIA publishes no scaled score.
U.S. exam voucher: $544.
Experience, renewal and retakes
Recommended experience: At least 10 years of general hands-on IT experience, including 5 years of broad hands-on IT security experience.

First retake: No waiting period after a first failed attempt.
Third attempt and later: Wait at least 14 calendar days from the previous attempt.
SecurityX (CAS-005) domain weights
Security Engineering and Security Architecture make up 58% of the exam together. That is where most of the blueprint sits, but none of the four domains is small enough to ignore.
| Domain | Topic | Official weight |
|---|---|---|
| Domain 1 | Governance, Risk, and Compliance | 20% |
| Domain 2 | Security Architecture | 27% |
| Domain 3 | Security Engineering | 31% |
| Domain 4 | Security Operations | 22% |
How our SecurityX practice tests are written
Scenario first. CAS-005 expects experienced judgment. The questions put a requirement, failure condition or design constraint in front of you and ask for the BEST, FIRST, NEXT or MOST appropriate response.
Mapped to the current blueprint. Practice content follows the four CAS-005 domains and their published weights. The short mixed sets sample across them; the domain tests stay narrow when you need focused work.
Technical choices have consequences. A control can be valid and still be the wrong answer because it breaks availability, ignores a trust boundary or solves a different layer of the problem. That distinction is where advanced practice becomes useful.
Original questions. The practice content is written for study against the published objectives. It does not reproduce live exam questions.
CompTIA SecurityX preparation tips
Study strategy
Start with your weakest heavy domain. Security Engineering is 31% and Security Architecture is 27%. If one of those is weak, it can keep showing up all the way through a 90-question paper.
Study decisions, not lists. When you review cryptography, identity, Zero Trust or incident response, ask what condition would make one control better than another. SecurityX is full of answers that are technically true but wrong for the constraint.
Keep a lab in the plan. CAS-005 includes performance-based questions. Reading architecture diagrams and configuration examples helps, but hands-on practice is still part of preparing for the live exam.
Test-taking strategy
Use the full 165 minutes deliberately. The average works out to about 110 seconds per question at the 90-question maximum. Some scenarios deserve more; others should be answered and left behind.
Read the qualifier twice. BEST, FIRST and NEXT are different questions. A technically correct action can lose because it belongs one step later in the process.
Watch for the deciding constraint. Availability, evidence quality, blast radius, data sovereignty or least privilege often turns two plausible answers into one defensible answer.
