Searching for "CompTIA SecurityX practice tests" or "CompTIA SecurityX sample questions"? This guide explains exactly what's on the CAS-005 exam, breaks down each domain, and lets you try 10 realistic scenario-based questions — with full explanations for every answer choice.
CompTIA SecurityX — the rebranded, updated successor to CASP+ — is CompTIA's most advanced cybersecurity certification. It's designed for senior security engineers and security architects who design, build, and operate secure systems across hybrid, cloud, and on-premises environments. Unlike entry-level exams, SecurityX leans heavily on multi-paragraph scenarios where you must weigh business constraints, governance requirements, and technical trade-offs to pick the best answer — not just a correct one.
CompTIA recommends roughly 10 years of general hands-on IT experience, including at least 5 years in hands-on security roles, plus the knowledge covered by Network+, Security+, CySA+, Cloud+, and PenTest+ (or equivalent experience). This is an advanced, not entry-level, exam.
Every question on the exam — including the 10 practice questions below — maps to one of these four domains.
Security program documentation, risk management, third-party/vendor risk, threat modeling, compliance frameworks (NIST, ISO 27000, PCI DSS).
Zero Trust, cloud security architecture, network segmentation, deperimeterization (SASE/SD-WAN), and secure boundary design.
Automation and scripting, vulnerability management, advanced cryptography, key management, and CI/CD pipeline security — the largest domain.
SIEM and log analysis, threat hunting, incident response, malware analysis, and evidence handling during active incidents.

SecurityX questions are notoriously dense. Knowing the format before exam day is half the battle. Here's what to expect, plus a preview of what each of the 10 practice questions in this guide covers.
Most questions open with 3–6 sentences of business context: company type, constraints (deadlines, budgets, regulations), and a specific problem. You then choose the single best action from four options. Several distractors will be partially correct or technically true but incomplete.
Drag-and-drop, configuration, or click-based simulations — for example, matching controls to risks, ordering incident response steps, or configuring a firewall rule set. These test hands-on judgment, not just memorization.
Some exam deliveries include a live Linux virtual machine where you must complete a real task (e.g., a configuration or remediation step) — a unique feature of the SecurityX/CASP+ lineage.
Expect multiple answers that would help. The exam wants the option that most directly and completely addresses the stated requirement, given the stated constraints — that's the skill these 10 practice questions are designed to build.
| # | Domain | Scenario Topic |
|---|---|---|
| 1 | GRC | Third-party AI governance & sensitive data risk (GenAI SaaS approval) |
| 2 | Architecture | Zero Trust for hybrid enterprise access after a VPN compromise |
| 3 | Engineering | CI/CD pipeline integrity & software supply chain security |
| 4 | Operations | Ransomware containment & evidence preservation |
| 5 | Engineering | Cryptographic erase & key lifecycle management at cloud scale |
| 6 | GRC | Third-party risk management & SaaS governance onboarding |
| 7 | Architecture | Zero Trust & identity-centric access for contractors/admins |
| 8 | Engineering | CI/CD secrets management & deployment integrity |
| 9 | Engineering | Cryptographic control selection for multi-tenant data retirement |
| 10 | Operations | Incident response timeline, evidence preservation & backup protection |
Answer each scenario the way you would on the real CAS-005 exam. After you select an answer, you'll see whether it's correct along with a full explanation — including why each of the other options is wrong. This is a self-assessment tool, not an official CompTIA product.
A focused plan for candidates who already meet the recommended experience level and need structured review before exam day. Adjust the pace based on how comfortable you are with each domain.

These patterns show up constantly in scenario-based SecurityX questions — including several of the 10 practice questions above. Recognizing them is one of the fastest ways to raise your score.
In Practice Question 1, "encryption in transit and at rest addresses the primary confidentiality risk" is true — encryption does help. But the scenario also raises retention, model-training use, access control, auditability, and contractual obligations. The exam rewards the option that covers the full set of stated concerns.
You select the first answer that sounds like a real security control and move on, missing that the scenario listed multiple distinct risks the "correct" answer must cover.
Before reading the options, list every risk or requirement mentioned in the scenario. Then check each option against that full list — the best answer is usually the one that addresses the most of them.
Practice Questions 4 and 10 both include a tempting "power off the server immediately" option. It would stop the ransomware, but it destroys volatile evidence — and the scenario explicitly says isolation is available. Question 6 includes a "block the vendor permanently" option that ignores the fact that a risk-based review hasn't even happened yet.
You treat the exam like it's asking "what would stop the problem fastest" instead of "what is the best balance of containment, evidence, business need, and proportionality."
When an option uses words like "immediately," "permanently," "all," or "never," ask whether the scenario actually justifies that extreme — or whether a more measured, reviewable action achieves the same goal with less collateral damage.
In Practice Question 3, weekly vulnerability scans and TLS between CI/CD runners and the registry are both reasonable controls — but neither prevents an attacker with registry write access from pushing a malicious image that production then runs. Only signed artifacts with admission-time verification provide that integrity guarantee.
You pick a control that would help you find out something went wrong, when the scenario is asking how to prevent it from happening — or vice versa.
Ask: does this scenario want me to stop an event, detect an event after the fact, or recover from an event? Match the control type (preventive, detective, corrective) to that specific need.
Both Practice Questions 4 and 10 hinge on the fact that the scenario explicitly states isolation is possible without powering off the server. That detail is the key — it tells you the "best" answer must preserve volatile evidence (memory, running processes) while still stopping the spread.
You jump to "shut it down" as the safest containment move and overlook that the scenario gave you a less destructive option, plus an explicit requirement to support root cause analysis.
In any IR scenario, look for the standard sequence: contain (isolate) → preserve (volatile data, disk images, logs) → eradicate → recover. Pick the option that follows this order given the tools the scenario says are available.
Practice Questions 1 and 6 both describe a business unit wanting to approve a SaaS or generative AI tool quickly. The "best" answers require a structured review — data flow analysis, vendor risk assessment, contractual obligations, audit rights — rather than a single control like MFA, training, or an outright ban.
You answer as if the question is about endpoint or identity security, missing that GRC questions test whether you know the process a senior leader should require before approval — not just a technical safeguard.
When a scenario mentions vendors, SaaS, contracts, regulators, or "approval," default to thinking about risk assessment, data flow review, contractual terms, and residual risk acceptance — the GRC toolkit — before considering technical controls.
