Sample Exam Questions
Try these 12 original sample questions for CompTIA SecurityX CAS-005. Use them for study, self-assessment, and exam-scope review. They are not official CompTIA questions, copied live-exam content, or exam dumps.
Question 1
What this tests: senior-level risk trade-off
A business unit wants to launch a public API that exposes customer records to partner systems. Which security architecture step should come before implementation approval?
- A. Confirm data classification, authentication model, authorization boundaries, logging, rate limits, and third-party risk controls
- B. Publish the API first and review access controls after customers complain
- C. Share one administrator token with every partner
- D. Disable audit logging to reduce storage costs
Best answer: A
Explanation: SecurityX questions expect senior architecture judgment. Exposing customer records requires data classification, identity, authorization, monitoring, abuse prevention, and partner-risk controls before launch. The other choices create avoidable exposure or remove evidence.
Question 2
What this tests: zero trust design
An enterprise wants to reduce reliance on network location as the main trust signal. Which design direction best supports zero trust principles?
- A. Trust every device once it is on the internal network
- B. Use continuous identity, device posture, least privilege, segmentation, and policy evaluation for access decisions
- C. Remove multifactor authentication for administrators
- D. Put all applications on one flat network
Best answer: B
Explanation: Zero trust emphasizes explicit verification, least privilege, segmentation, and continuous evaluation rather than implicit trust based on network location. Flat networks and weaker administrator controls move in the wrong direction.
Question 3
What this tests: cryptographic control selection
A regulated application stores sensitive records in a database. Which design best protects data at rest while preserving operational control?
- A. Store records unencrypted and rely on a private subnet only
- B. Use strong encryption at rest with managed key controls, access policies, rotation planning, and audit logging
- C. Base64-encode all fields and call it encryption
- D. Put the encryption key in the same public repository as the application
Best answer: B
Explanation: Strong encryption requires real cryptographic protection and key management. Access policies, rotation, separation of duties, and audit logs matter for regulated workloads. Base64 is not encryption, and public key storage defeats the control.
Question 4
What this tests: secure automation
A team uses infrastructure as code to deploy cloud resources. How should security be integrated into the pipeline?
- A. Skip testing because automation is always safe
- B. Allow only manual console changes so nothing is recorded
- C. Store all deployment secrets in plain text pipeline logs
- D. Add policy checks, secret scanning, dependency review, and approval gates appropriate to risk
Best answer: D
Explanation: Senior security engineering uses automation with guardrails. Policy-as-code, secret detection, dependency checks, and risk-based approvals help prevent insecure deployments while preserving delivery speed. Manual untracked changes and exposed secrets increase risk.
Question 5
What this tests: governance and exception handling
A critical system cannot meet a new encryption standard before the compliance deadline. What should security leadership require?
- A. Deleting the standard from the policy repository
- B. Silent noncompliance because the system is important
- C. A documented risk exception with owner, compensating controls, expiration date, and remediation plan
- D. Asking auditors not to review the system
Best answer: C
Explanation: Governance does not mean pretending exceptions do not exist. A mature exception process documents accountability, compensating controls, time limits, and remediation. Silent acceptance or hiding the issue creates compliance and security risk.
Question 6
What this tests: enterprise segmentation
A legacy manufacturing system cannot be patched and must continue operating. Which control best reduces enterprise risk?
- A. Disable all monitoring because it is legacy
- B. Connect it directly to the internet for vendor convenience
- C. Give every employee local administrator access to it
- D. Place it on a segmented network with tightly controlled access, monitoring, and compensating controls
Best answer: D
Explanation: When patching is constrained, segmentation and compensating controls reduce exposure. Monitoring remains important because vulnerable legacy systems can be high-value targets. Internet exposure and broad admin access would increase risk.
Question 7
What this tests: security architecture review
A new SaaS vendor will process confidential employee data. Which review area is most important before onboarding?
- A. Whether the vendor can bypass procurement
- B. The vendor’s logo color only
- C. Contractual security terms, data handling, identity integration, incident notification, audit evidence, and exit procedures
- D. Whether the vendor has a large social-media following
Best answer: C
Explanation: Third-party risk review should cover data protection, access, monitoring, contractual rights, incident processes, and offboarding. Branding or popularity does not prove security fitness.
Question 8
What this tests: incident response architecture
An organization wants better ransomware readiness. Which architecture improvement is most relevant?
- A. Backups stored only on the same compromised file share
- B. A policy saying ransomware is prohibited
- C. One shared administrator account for faster recovery
- D. Immutable or protected backups, tested restoration, segmentation, endpoint controls, and response playbooks
Best answer: D
Explanation: Ransomware resilience requires technical and operational controls: protected backups, tested recovery, segmentation, detection, privilege management, and response planning. A policy alone does not create recoverability.
Question 9
What this tests: privileged access management
Administrators currently use standing domain-admin privileges for daily work. What is the best improvement?
- A. Disable MFA because administrators are trusted
- B. Let all users share one administrator password
- C. Use just-in-time privileged access, separate admin accounts, MFA, approval workflows, and session logging
- D. Remove logging to protect administrator privacy
Best answer: C
Explanation: Privileged access should be limited, verified, monitored, and time-bound. Standing broad privileges increase blast radius. Shared passwords, disabled MFA, and missing logs undermine accountability.
Question 10
What this tests: cloud security posture
A cloud environment has many accounts and subscriptions with inconsistent configurations. What should security architects implement?
- A. A request that each team manually check settings once a year
- B. Centralized guardrails, posture monitoring, baseline policies, and automated remediation where appropriate
- C. One unrestricted administrator role for all workloads
- D. No tagging or inventory because it slows delivery
Best answer: B
Explanation: Enterprise cloud security depends on repeatable guardrails and visibility. Centralized baselines, posture management, inventory, and automation help reduce drift. Manual annual checks are insufficient for fast-changing environments.
Question 11
What this tests: security operations maturity
A SOC receives thousands of low-quality alerts and misses a real incident. What is the best strategic response?
- A. Tune detections, improve correlation, map alerts to use cases, and measure fidelity and response outcomes
- B. Disable the SIEM permanently
- C. Increase alert volume without reviewing value
- D. Stop documenting incidents
Best answer: A
Explanation: Mature security operations improve signal quality and response effectiveness. Detection tuning, use-case mapping, correlation, and metrics reduce noise while preserving important visibility. More alerts alone do not improve security.
Question 12
What this tests: SecurityX route fit
A candidate designs security architecture, leads engineering decisions, and evaluates enterprise risk across cloud, identity, operations, and governance. Which CompTIA route is the closest fit?
- A. SecurityX CAS-005
- B. Network+ only
- C. A+ Core 1
- D. Data+ V2
Best answer: A
Explanation: SecurityX is CompTIA’s advanced security architecture and engineering route. A+, Network+, and Data+ serve different skill levels or domains and do not match the senior enterprise security scope described.
