About the CompTIA SecurityX exam
SecurityX (CAS-005) is CompTIA's expert-level security certification and the exam that CASP+ became. It covers governance and risk, security architecture, security engineering and security operations for practitioners who design and build controls rather than monitor them.

CompTIA SecurityX carries the exam code CAS-005 and replaces CASP+. The blueprint changed along with the name. Four domains split the exam: governance, risk and compliance at 20 percent, security architecture at 27 percent, security engineering at 31 percent, and security operations at 22 percent. Well over half of it therefore sits in architecture and engineering, which is where candidates arriving from Security+ or CySA+ lose most of their marks. Those two domains ask you to choose a design and defend it against constraints such as legacy systems that cannot be patched, regulatory scope, a merger that has to be integrated, and a fixed budget. Recalling what a control does will not answer them. The exam runs up to 90 questions in 165 minutes and mixes multiple-choice items with performance-based tasks. CompTIA reports it as pass or fail with no scaled score, so there is no published number to aim at. Treat every domain as one you have to be competent in rather than one you can average away. SecurityX is written for people already doing the work: security architects, senior engineers, technical leads and consultants who own designs rather than tickets. CompTIA keeps it a practitioner credential rather than a management one, so the questions stay technical even inside the governance domain, where you are asked how a control satisfies a requirement and what evidence would prove it. This course follows the CAS-005 objectives domain by domain, with practice questions, flashcards and performance-based tasks weighted the way the real exam is.
Exam Domains Covered
Exam Format & Details
Up to 90 questions in 165 minutes, mixing multiple-choice items with performance-based tasks. CompTIA reports the result as pass or fail and publishes no scaled passing score for CAS-005. The CompTIA Store lists the individual voucher at USD 499. Booked through Pearson VUE, at a test centre or online.
Why Practice Questions Matter
SecurityX questions are long. One item can run a full paragraph of context before it asks anything, and all four answers are often defensible controls with a single one that fits the constraint buried in the scenario. What you practise here is finding that constraint before you read the options, which is a reading habit rather than a recall drill. Several hundred questions in this format teach you to spot the sentence that decides the answer, and every explanation says why the near-miss option fails, because that distinction is what the exam actually tests.
Sample Practice Questions
The following questions are a preview of the type of syllabus-aligned questions you will practise in CertCrush. They reflect the format and reasoning style of the CompTIA SecurityX exam — not actual exam content.
Q1.Protective DNS blocked eleven thousand queries a day for six months and now blocks a few hundred, with no change to the threat feed and no reduction in user population or internet traffic volume. Endpoint telemetry shows browsers resolving names successfully. What is happening, and which combination of changes restores the control?
- A.Clients are resolving through browser based encrypted DNS, so policy manage it on managed devices and block known public encrypted DNS endpoints at egress while permitting your own encrypted resolver
- B.Clients are resolving through browser based encrypted DNS, so block all outbound traffic on ports 53 and 853 except to the internal resolvers
- C.The resolver cache is now warm enough that most queries never reach the policy engine, so shorten cache lifetimes on the protective resolver
- D.The threat feed provider has consolidated its indicators, so add a second feed and lower the confidence threshold for blocking
Domain: Security Engineering
Q2.A payments service and a checkout service run in a container platform and currently authenticate to each other with a shared secret held in a configuration file, refreshed manually each year. You want mutual authentication that survives the workload being rescheduled onto any node. What should the design use?
- A.Issue each workload a certificate bound to the node it runs on, and re-issue on reschedule
- B.Issue each workload a platform-attested identity with a short-lived, automatically rotated credential naming the workload rather than its host
- C.Move the shared secret into a managed secrets store and rotate it automatically every thirty days
- D.Accept connections based on the source address range assigned to the platform's node pool
Domain: Security Architecture
Q3.A security architect has no mandate over a product engineering group that reports elsewhere, and needs the group to start signing container images. The group has two open headcount and a launch in six weeks. What approach is most likely to succeed?
- A.Send the signing standard with a compliance deadline and copy the group's director.
- B.Arrive with the four-line pipeline change already tested against a copy of the group's build, and ask only for that.
- C.Escalate to the executive sponsor and request a mandate covering all product engineering groups.
- D.Add the group's non-compliance to the risk register and review it at the next steering committee.
Domain: Governance, Risk, and Compliance
Q4.Four teams issue certificates through different routes: one uses a public authority's console, one uses a cloud certificate manager, one uses an internal authority, and one buys certificates on a corporate card. A five-hour outage was caused by an expired certificate nobody owned. The board asks for a solution. Which first step actually addresses the failure?
- A.Stand up a new consolidated internal certificate authority and migrate all issuance to it
- B.Configure expiry alerting at thirty days on every certificate currently in the monitoring platform
- C.Run active discovery across scans, platform APIs and transparency logs into one register with an owner named per certificate
- D.Extend validity periods to three years so renewals occur less frequently
Domain: Security Architecture
Q5.A Statement of Applicability being prepared for a first certification audit marks every Annex A control as applicable and implemented, including several the organization plainly does not perform, such as controls for development environments it does not operate. The consultant says a full sheet looks stronger to an auditor. What is the correct approach?
- A.Mark every control applicable as advised, since claiming more coverage cannot be penalised at audit.
- B.Record honest applicability decisions, including controls deliberately excluded, each with a stated justification.
- C.Delete the rows for controls the organization does not perform so the sheet contains only live controls.
- D.Mark the questionable controls as applicable but not yet implemented, with no target date, so the sheet stays complete.
Domain: Governance, Risk, and Compliance
