CompTIA SecurityX (CAS-005) Practice Test

SecurityX is designed for senior security engineers and security architects who are responsible for designing, implementing, and managing security solutions rather than simply administering them. Ideal candidates typically hold roles such as Security Architect, Senior Security Engineer, Security Operations Lead, Security Integration Engineer, or Systems Requirements Planner.

The certification is also aligned with multiple NICE Cybersecurity Workforce Framework work roles and DoD 8140 positions, making it particularly relevant for professionals in government, defense contracting, and federal agency environments. Candidates should have substantial hands-on experience and be operating at a level where they are making architectural decisions and leading security initiatives, not just executing them.

CompTIA does not enforce formal prerequisites for CAS-005, but recommends a minimum of 10 years of general hands-on IT experience, including at least 5 years of hands-on technical security experience. Candidates are expected to possess knowledge equivalent to CompTIA Network+, Security+, CySA+, Cloud+, and PenTest+ — either through those certifications or equivalent professional experience.

In practice, candidates who attempt SecurityX without a strong foundation in network security, cryptography, cloud infrastructure, and security operations often find the exam extremely challenging. Professionals who have already earned Security+ and CySA+ (or CISSP/equivalent) and are working in senior technical security roles are the most common and well-prepared candidates.

The CAS-005 exam consists of a maximum of 90 questions, delivered in a maximum of 165 minutes. Question types include both multiple-choice and performance-based questions (PBQs), where candidates must interact with simulated environments or scenarios to demonstrate applied skills. The exam is available in English via online proctoring through Pearson VUE's OnVUE platform or at a physical Pearson VUE testing center.

The exam uses a pass/fail grading model — no scaled score is reported. CompTIA does not publish a numeric passing threshold for SecurityX; candidates simply receive a pass or fail result. The certification is valid for three years and can be renewed through CompTIA's Continuing Education (CE) program by earning 75 CEUs within the three-year cycle.

• 1.Security Engineering (31%): Applies secure configurations and integrates security solutions across enterprise systems, including cloud-native and hybrid architectures, containers, CI/CD pipelines, and infrastructure-as-code. Covers PKI, cryptographic protocol selection, key management, and the security implications of AI and emerging technologies.
• 2.Security Architecture (27%): Designs secure network and system architectures for complex environments including on-premises, cloud, and hybrid. Addresses zero trust principles, network segmentation, identity federation, CASB, shadow IT detection, shared responsibility models, and integration of security controls across multi-vendor ecosystems.
• 3.Security Operations (22%): Supports continuous security operations through automation, monitoring, threat hunting, and incident response. Covers SIEM/SOAR integration, vulnerability management, digital forensics, log analysis, and coordinating response activities across enterprise and third-party stakeholders.
• 4.Governance, Risk, and Compliance (20%): Addresses enterprise risk management frameworks, regulatory compliance (GDPR, HIPAA, CMMC, FedRAMP), third-party risk, security policy development, privacy requirements, and aligning security programs with business objectives and legal obligations.

• Download and study the official CAS-005 Exam Objectives document from CompTIA's website — it lists every domain, sub-domain, and example topic tested, and should serve as your primary study outline.
• Use CompTIA's official CertMaster Learn and CertMaster Labs for CAS-005, as the labs simulate performance-based question scenarios directly comparable to what appears on the exam.
• Focus heavily on Security Engineering (31%) and Security Architecture (27%), which together account for 58% of the exam. Prioritize hands-on practice with cloud security configurations, cryptographic implementations, and zero trust architecture design.
• Practice performance-based questions (PBQs) extensively — these scenarios require you to configure, analyze, or troubleshoot within simulated environments and cannot be answered through memorization alone. Third-party practice platforms like PocketPrep or Jason Dion's Udemy course include PBQ-style questions.
• Study DoD 8140 work role mappings and NICE Cybersecurity Workforce Framework alignment for SecurityX, as understanding these frameworks helps contextualize exam scenarios related to governance, compliance, and security architecture roles.
• Review real-world case studies involving enterprise security architecture decisions — the exam tests judgment and design rationale, not just technical facts. Focus on scenarios involving cloud migrations, zero trust implementations, and incident response at scale.
• If you hold an active CASP+ (CAS-004), review what changed in CAS-005: expanded AI/ML security topics, updated cloud security coverage, and deeper coverage of automation and DevSecOps are key additions that may not be in older study materials.

SecurityX holders command some of the highest salaries in the CompTIA certification portfolio. The average reported salary for SecurityX practitioners is approximately $165,000, with security architects and senior security engineers typically earning between $155,000 and $200,000+ depending on sector and geography. The certification's DoD 8140/8570 approval makes it a direct pathway to roles within federal agencies and defense contractors — organizations including General Dynamics, Booz Allen Hamilton, and Leidos actively seek candidates with this credential.

As the capstone of the CompTIA Cybersecurity Career Pathway, SecurityX is positioned above Security+, CySA+, and PenTest+ and signals to employers that a candidate operates at the architect and integrator level rather than the analyst or administrator level. Compared to alternatives like CISSP (which is management-focused) or OSCP (which is offense-focused), SecurityX occupies a distinct niche as a hands-on, vendor-neutral credential validating advanced defensive architecture and engineering skills. Employers in both the public and private sectors — including Target, Ricoh, and Exxon Mobil — recognize the certification for senior technical security hiring.
