CISA Practice Questions (Certified Information Systems Auditor)
CISA is the credential IT audit, assurance, and security-control roles screen for, and the exam is far more about audit judgment than technical recall. This is the biggest practice bank of its kind: 10 full-length timed forms, 1,500 original questions across all five domains at official weighting, with a clear rationale for every answer. Take a free timed practice test first, then unlock the full bank for $99 one time.

The Certified Information Systems Auditor (CISA) exam is a vendor-neutral certification for IT audit, assurance, and control professionals. The exam has 150 multiple-choice questions, a 4-hour (240-minute) time limit, and a scaled passing score of 450 on a 200 to 800 range. It covers five domains: Information Systems Auditing Process, Governance and Management of IT, Information Systems Acquisition Development and Implementation, Information Systems Operations and Business Resilience, and Protection of Information Assets. Scoring is on the total scaled score, so there is no per-domain minimum. It is widely recognized as a standard requirement for IT audit and assurance roles.

The biggest CISA bank, with a rationale for every answer
What you get with the full bank
A large bank of original CISA practice questions written to the current ISACA CISA Exam Content Outline, effective 1 August 2024. Full coverage of all five domains, weighted to the official blueprint: Information Systems Auditing Process, Governance and Management of IT, Information Systems Acquisition Development and Implementation, Information Systems Operations and Business Resilience, and Protection of Information Assets.
A clear rationale for every question. We explain why the correct answer is correct and why each other option is wrong, so you build the audit reasoning the exam actually tests rather than memorizing answers. The bank is built around the CISA audit mindset: FIRST-step sequencing, BEST-evidence comparisons, and GREATEST-concern prioritization, where most or all options are true and a single qualifier decides the key.
Two ways to practice. Exam mode is a timed, full-length 150-question form that matches the real domain weighting, so you rehearse under exam conditions. Study mode lets you practice by domain, review rationales as you go, and retry the questions you missed.
The five CISA domains and their official weight
Every one of the 10 forms is built to the same domain weighting, so each is a true full-length rehearsal of the real exam.
Information Systems Auditing Process (18%)
Risk-based audit planning, IS audit standards and guidelines, the audit charter and independence, evidence collection and reliability, sampling, CAATs and data analytics, and communicating results. The process backbone of the exam.
Governance and Management of IT (18%)
IT governance frameworks, strategy alignment, policies and standards, enterprise and IT risk management, organizational structure and segregation of duties, performance measurement, and third-party governance. The management-side reasoning many candidates underestimate.
Information Systems Acquisition, Development and Implementation (12%)
The business case and feasibility, project governance, SDLC and Agile controls, testing strategies, data conversion and migration, go-live readiness, post-implementation review, and change and release management. The smallest domain by weight.
Information Systems Operations and Business Resilience (26%)
One of the two heaviest domains. IT service and operations management, incident and problem management, backup and restoration, business impact analysis, business continuity, and disaster recovery with RTO and RPO. Where many candidate points are won or lost.
Protection of Information Assets (26%)
The other heaviest domain. Information security governance, logical access and identity management, authentication and privileged access, encryption and key management, data classification and privacy, security monitoring, and emerging-tech risk across cloud, AI, and IoT.

How CISA is scored
The CISA exam has 150 multiple-choice questions and a 4-hour (240-minute) time limit. The passing score is 450 on a scaled range of 200 to 800. This is a proficiency threshold set on the total scaled score, not a raw percentage and not a per-domain cutoff, so a strong domain can offset a weaker one.
Because the scale is not a raw percentage, there is no published question-to-score formula. Community consensus is that passers get roughly 70 percent or more of items right, but the exact raw cut varies by form and ISACA does not publish the conversion. Our exam-mode form mirrors the 150-question, domain-weighted structure so your practice percentage tracks close to real exam conditions.
Time is rarely the binding constraint at roughly 1 minute 36 seconds per item. The real difficulty comes from wording: most items make several options technically true, then use a single qualifier such as PRIMARY, BEST, FIRST, or GREATEST to decide the answer. Read the qualifier before the options.
Who uses the CISA?
CISA is a common requirement for IT auditor, IT assurance, and IT risk and control roles, and it is frequently listed as a preferred or required credential for internal audit and compliance positions. Organizations that hire heavily for these roles routinely list it as a requirement or a strong preference.
A CISA prep approach (about 30 days)
Days 1-3: Take the free diagnostic and read your domain breakdown
Start with the free 25-question timed diagnostic. It scores you domain by domain so you can see exactly where you stand before spending a cent. Your two weakest domains become the focus of the plan.
Days 4-14: Study mode by domain, weakest first
Work through study mode one domain at a time, reading the rationale on every question including the ones you get right. Operations and Business Resilience and Protection of Information Assets carry the most weight, so do not leave them for last.
Days 15-24: Drill the audit-judgment patterns
The exam turns on qualifiers. Work the FIRST-step sequencing, BEST-evidence comparison, and GREATEST-concern items until you instinctively rank options on the axis the qualifier names, and never pick the option where the auditor fixes the control.
Days 25-29: Full-length timed forms
Sit exam-mode forms under a strict 240-minute clock. Aim to consistently clear the pass approximation with time to spare, and review every miss by domain.
Day 30: Light review and rest
Review only your flagged and missed items from the last two forms. Do not cram new material the day before. Settled recall beats last-minute volume.
Common CISA mistakes
Answering as an operator, not an auditor
The single biggest trap. An option where the auditor personally patches, configures, or remediates a control is almost always wrong, even when it would solve the problem, because it destroys independence. Auditors assess and report, they do not fix.
Ignoring the qualifier
Most items make several options true. PRIMARY, BEST, FIRST, and GREATEST each select a different answer. Read the qualifier first, then rank the options on the axis it names.
Reporting before establishing extent and cause
On FIRST-step items, the earliest correct action is usually to understand, assess, or gather evidence. Report and remediate come later. Picking report too early is a classic miss.
Underweighting the heavy domains
Operations and Business Resilience and Protection of Information Assets are each 26 percent, 52 percent of the exam combined. Candidates who over-invest in the audit process domain and skip these lose the most points.
