CompTIA SecurityX CAS-005: 420 Practice Questions

This course contains the use of artificial intelligence.

Practice the decisions behind enterprise security. Work through 420 original English questions for CompTIA SecurityX V5, exam CAS-005, using the published objectives version 3.0 checked on October 10, 2026. Each question has one best answer, feedback for every option, an overall explanation, and a focused study tip.

The scenarios ask you to distinguish a working control from a documented claim, locate a failed trust boundary, interpret security evidence, and choose a response that respects business and operational constraints. Examples include recovery copies that are too old or unusable, signed but stale authorization evidence, runtime permissions outside an image scanner's scope, and incident containment that must preserve industrial safety.

Your practice path

• Governance, Risk, and Compliance: 60 questions. Policies, accountability, supplier risk, assurance scope, threat modeling, and AI security.
• Security Architecture: 60 questions. Resilience, secure development, control placement, access design, cloud responsibilities, and zero trust.
• Security Engineering: 60 questions. IAM and network troubleshooting, endpoint controls, hardware trust, constrained systems, automation, and cryptography.
• Security Operations: 60 questions. Monitoring, vulnerability mitigation, threat hunting, intelligence, and incident artifacts.
• Two mixed timed sets: 90 questions each. Each set uses 18 governance, 24 architecture, 28 engineering, and 20 operations questions, an author rounding of the official domain weights.

Use the focused drills in short study sessions before trying the mixed sets. The focused drills have an optional 120-minute timer. The mixed sets allow 165 minutes, matching the published exam time and maximum question count for pacing practice. Review the reason each tempting alternative fails, then revisit the relevant topic before repeating a set.

What the practice measures

The course addresses all 23 main objectives through representative decision tasks. It combines foundational distinctions with scenarios about control scope, dependencies, failure modes, evidence quality, and recovery. It is a question course, with no video lectures or interactive labs, and is intended to complement study of the official objectives and hands-on experience.

The actual exam contains multiple-choice and performance-based questions and may have fewer than 90 questions. These sets use single-answer multiple-choice questions; they do not reproduce interactive performance-based tasks or the full exam experience. The course's 80% checkpoint is an author-selected learning target. SecurityX uses a pass/fail result with no scaled score; this checkpoint is not an official passing score or a pass guarantee.
