Written to the current CAS-005 objectives
The question banks use CompTIA SecurityX CAS-005 Exam Objectives Version 3.0. The four domains are Governance, Risk, and Compliance; Security Architecture; Security Engineering; and Security Operations.
This is senior-practitioner material. The questions focus on architecture trade-offs, engineering choices, cloud and hybrid design, identity, cryptography, automation, threat hunting, incident response, governance and AI security.
The live exam also contains performance-based questions. These practice tests cover the multiple-choice body with single-answer and choose-TWO questions; hands-on tasks still belong in a lab.
Two hours and forty-five minutes leaves room to reason. It also exposes hesitation.
SecurityX is not Security+ with longer wording. A strong answer often loses because it ignores one constraint: trust boundary, recovery requirement, authorization path, evidence quality or operational impact.
How it’s built
- 90 questions in a 165-minute practice window
- 18 Governance, Risk, and Compliance questions
- 24 Security Architecture questions
- 28 Security Engineering questions
- 20 Security Operations questions
- Six choose-TWO questions in every test
Difficulty and answer format
- 14 easy, 41 medium and 35 hard questions
- 84 single-answer questions
- Six choose-TWO questions, scored all-or-nothing
- No negative marking in these practice tests
- Scenario-led BEST, FIRST, NEXT and MOST decisions
- The same matrix runs through all ten papers
What you review
- Every question carries a student-facing explanation
- The explanation resolves why the keyed answer wins
- The strongest wrong answer is addressed where it matters
- Questions are mapped to the CAS-005 domain and objective
- That makes a repeated weak area easier to spot across papers
The hard part is seeing the blind spot the diagram did not show
This question comes from SecurityX Practice Test 3. Both correct choices address a different gap in the same threat model.
An enterprise is threat-modeling an externally exposed collaboration platform before a major divestiture. The team wants to uncover risks that ordinary architecture diagrams may miss, especially around misuse by legitimate users and services that were created outside formal IT processes. Which TWO activities are MOST valuable?
- ADevelop abuse cases that describe how authorized capabilities could be misused
- BRestrict the review to known vulnerability scanner findings on managed servers
- CAssume existing trust relationships remain valid until the divestiture is complete
- DEnumerate unsanctioned assets and accounts connected to the platform
Why A and D
Abuse cases expose harmful uses of legitimate functions. Enumerating unsanctioned assets and accounts finds attack surface that ordinary architecture diagrams can miss. Together they cover misuse and shadow resources.
Why B and C miss the requirement
Vulnerability findings alone do not model misuse by legitimate capabilities. Assuming inherited trust is safe is exactly the kind of blind spot a divestiture threat model should challenge.
Every 90-question paper uses the same four-domain allocation
Security Engineering is the largest domain at 31%, followed by Security Architecture at 27%. The practice blueprint converts those percentages into a fixed whole-question split so one paper can be compared with the next.
| CAS-005 domain | CompTIA weight | Questions per practice test | Practice share |
|---|---|---|---|
| 1.0 Governance, Risk, and Compliance | 20% | 18 | 20.0% |
| 2.0 Security Architecture | 27% | 24 | 26.7% |
| 3.0 Security Engineering | 31% | 28 | 31.1% |
| 4.0 Security Operations | 22% | 20 | 22.2% |
Architecture and Engineering account for 52 of the 90 questions in each practice test.
