ISC2 CISSP practice exam: 1,000 questions across all eight domains, weighted to the vendor's own outline. 40 free CISSP practice exam questions.
1,000 CISSP practice questions across all eight ISC2 domains, weighted to the vendor's published percentages, each with an explanation that teaches the topic rather than restating the answer.The ISC2 CISSP practice exam on this page holds 1,000 questions covering all eight domains of the Certified Information Systems Security Professional Common Body of Knowledge, written to the exam outline ISC2 put into effect on 15 April 2024, which is the version in force. CISSP is the credential that moves a practitioner into a governing role, and the paper reflects that: it asks what a manager accountable for a decision should do, not which command produces the output. Every question here carries an explanation, and every explanation cites the ISC2 objective it answers to.
The bank is weighted to the percentages ISC2 publishes, domain by domain, rather than to whatever was easiest to write. The counts below are what you receive.
| Domains | Weighting | Questions |
| 1. Security and Risk Management | 16% | 160 |
| 2. Asset Security | 10% | 100 |
| 3. Security Architecture and Engineering | 13% | 130 |
| 4. Communication and Network Security | 13% | 130 |
| 5. Identity and Access Management (IAM) | 13% | 130 |
| 6. Security Assessment and Testing | 12% | 120 |
| 7. Security Operations | 13% | 130 |
| 8. Software Development Security | 10% | 100 |
Domain 1 is the largest and the one candidates underestimate, because governance, risk treatment, the ISC2 code of ethics and the personnel controls all live there and none of them is technical. Domain 3 carries the security models, the whole of cryptography and physical design. Domain 5 is identity, federation and the access control models. Domain 7 is the widest operationally - investigations, monitoring, incident response, recovery and personnel safety - and domain 8 is the only one that puts source code in front of you. Within each domain the questions are spread across the vendor's own content bullets, so no single sub-objective absorbs a domain's whole allocation.
This is the preparation mistake that costs experienced engineers the paper. CISSP is written from the position of somebody accountable for a decision, so the correct answer is frequently the one that is slower, more expensive and more procedurally correct than the fix a hands-on practitioner would reach for first. A scenario about a failing control usually wants the governance response - who owns the risk, who accepts it, what the policy requires - rather than the remediation. Life safety outranks every other objective, and any option that protects an asset at a person's expense is wrong regardless of how sound the engineering is. The questions here are written in that register throughout: the stems are business scenarios with a decision in them, and the distractors are the technically competent answers that are not the accountable one.
Every explanation here states the principle that decides the question, then isolates the single distinction the question turns on, then names the boundary where the ruling would come out the other way. None of them restates the option it is explaining, which is the difference between an explanation and an answer key - a paragraph that tells you the correct answer was correct teaches nothing the moment you get it wrong. Each one closes by citing the ISC2 objective it belongs to, so a wrong answer sends you to a named place in the outline rather than to a topic you have to guess at.
ISC2 uses advanced item types alongside multiple choice, and a bank made only of four-option questions does not prepare anybody for them. Just over a fifth of the questions here are drag-and-drop, where you sort items into categories and one item deliberately belongs in neither. Roughly a third are multiple-response, where the number of correct answers is not given away. Domain 8 carries the source-level items, where a short snippet of Python, Java, YAML or a manifest is on screen and the question asks what property of it an attacker would build on - judgment about code rather than recall of syntax, which is what the paper actually asks.
Exam Coach AI sits next to the question while the clock is running. Ask it what a term means, what separates two things candidates confuse, or when you would choose one control over another, and it explains the idea. It will not tell you which option to pick on the question in front of you, and it will decline if you ask - the point is to close the gap in your understanding while you are still in the exam, not to hand over an answer you will not have on the day. That matters more on CISSP than on a technical paper, because the thing that goes wrong here is usually a definition sitting a few degrees off true: due care against due diligence, a recovery time objective against a recovery point objective, mandatory against discretionary access control. Those are cheap to correct the moment you notice them and expensive to carry into the exam hall.
Most people arrive here from CompTIA's track, and the distance is larger than the topic lists suggest. Security+ asks what a control is; CISSP asks who is accountable for it and what happens when it fails. The vocabulary carries over almost completely and the register does not. If the gap looks steep, the CompTIA Security+ SY0-701 practice exam is the right place to close the technical foundation first, and the CompTIA CySA+ CS0-004 practice exam overlaps this bank's assessment, testing and operations domains most directly - it covers the monitoring, detection and incident work in domains 6 and 7 at a hands-on level, which is the layer CISSP asks you to govern rather than perform. Neither is a prerequisite ISC2 recognizes; both shorten the distance.
The pass mark here is 70% of the questions in your sitting, applied to our own bank. Each launch draws 120 questions from the pool of 1,000, weighted the same way the full bank is, at 90 seconds a question for a three-hour sitting - which is the shape of the real paper. Results break down by domain, so a failed attempt tells you which of the eight to go back to rather than giving you one number. Because the draw is weighted, a weak domain shows up in the same proportion it will on the day, which means a score of 68% tells you something specific about where the missing two percent lives rather than leaving you to re-read everything. Mistake review keeps every question you got wrong with its full explanation, so a second pass is targeted at the eight or nine ideas that actually cost you the attempt.
40 questions are free, and they are spread across all eight domains rather than clustered in the first one - so the preview shows you the register of the harder domains as well as the easy entry points. They include drag-and-drop and multiple-response items, and every free question carries its full explanation and its objective citation, which is the fastest way to judge whether the explanations here are worth paying for. Read two or three of them against the option they explain: if an explanation could be deleted and leave you no worse informed, it is an answer key, and that is the comparison this preview exists to let you make before you spend anything.
