PECB ISO/IEC 27001 Lead Auditor Practice Test
Free 20-question practice tests for the current PECB ISO/IEC 27001 Lead Auditor outline. Mixed sets cover all seven competency domains; focused sets let you stay on one domain. Each test uses about 45 minutes, keeping the same 2.25-minute-per-question pace as the 80-question, three-hour exam.
Mixed set — PECB ISO/IEC 27001 Lead Auditor practice tests
Use these first. The five mixed sets spread questions across all seven competency domains, with more attention on the heavier parts of the PECB blueprint. Domain 5, Conducting an ISO/IEC 27001 audit, carries the largest share at 22.5%.
Domain-wise — focused PECB Lead Auditor practice tests
A mixed set tells you where the gap is. These seven tests let you stay there for 20 questions instead of jumping between domains.
Twenty questions finds the weak spot.
Eighty shows whether your judgment holds for three hours.
The free sets are built for diagnosis. The full-length tests are the dress rehearsal: 80 questions in 180 minutes, the fixed seven-domain PECB distribution, three options per question, and a raw score measured against the 70% pass line.

How to use these tests in a study plan
Start short, then go long. The point is to spend your full-length attempts after you already know which domain needs work.
Benchmark
Sit two mixed sets before a heavy revision block. Look for a pattern in the misses: ISMS requirements, audit evidence, preparation, fieldwork, or something else.
Start with Practice Test 1 →Drill the gap
Move to the matching domain test and stay there until the scenarios stop catching you on the same mistake. Then return to a mixed set.
Practice Domain 5 →Dress rehearsal
When your domain work is stable, sit all 80 questions under the full 180-minute clock. Open-book does not make three hours feel short until you start looking up too much.

PECB's 2026 candidate handbook uses an 80-question multiple-choice exam built around ISO/IEC 27001:2022 and seven competency domains.
What the credential covers
The PECB ISO/IEC 27001 Lead Auditor path is for professionals who audit information security management systems and lead audit work against ISO/IEC 27001. The training objectives cover interpreting the standard from an auditor's perspective, evaluating conformity, planning and conducting audits, closing them properly, and managing an audit program.
The exam is open book. That changes the preparation problem. You do not need to memorize every line of the standard, but you do need to know when a question is testing audit evidence, an ISO/IEC 27001 requirement, or the auditor's next action. Looking up every answer is too slow.
Exam format
Questions: 80 multiple-choice questions.
Duration: 3 hours / 180 minutes.
Passing score: 70%.

PECB ISO/IEC 27001 Lead Auditor domain weights
The counts below come straight from PECB's current 80-question blueprint. Domain 5 is the biggest block. Domain 6 is the smallest.

| Domain 1 | Fundamental principles and concepts of an information security management system (ISMS) | 13 | 16.25% |
| Domain 2 | Information security management system (ISMS) and ISO/IEC 27001 requirements | 8 | 10% |
| Domain 3 | Fundamental audit concepts and principles | 14 | 17.5% |

How our practice tests are written
Original questions, current outline. The questions are written for practice against PECB's current seven-domain structure. No live exam content is reproduced.
Auditor decisions, not clause-number trivia. PECB's multiple-choice format includes scenarios, and half of the current blueprint is assigned to evaluation-level questions. The useful practice is deciding what the evidence supports and what the auditor should do next.
Mixed sets follow the blueprint. Domain 5 appears more often than Domain 6 because the exam does the same. The domain tests deliberately break that balance so you can spend 20 questions on one weak area.
The timer keeps the real pace. Three hours for 80 questions is 2.25 minutes per question. A 20-question set therefore runs at about 45 minutes.
The limit is length. A 20-question set is good for diagnosis. It cannot show whether your concentration and reference lookup stay efficient across the complete 180-minute paper. That is what the full-length tests are for.
PECB ISO/IEC 27001 Lead Auditor exam preparation
Study strategy
Start with Domain 5. Conducting an ISO/IEC 27001 audit is 22.5% of the paper, or 18 of 80 questions. Evidence gathering, interviews, sampling and findings deserve more time than the smallest domains.
Learn the audit as a sequence. Preparation, evidence collection, findings, conclusions and follow-up are easier to remember when they sit in one flow. Questions often turn on what should happen next.
Know where to look. Open-book works only when the book is familiar. Build a quick route to the clauses and audit concepts you repeatedly need instead of searching from page one.
Test-taking strategy
Read the scenario before the options. PECB scenario sets can feed several questions from one case. Missing one condition in the setup can contaminate more than one answer.
Separate evidence from opinion. When two choices sound plausible, prefer the one tied to objective evidence, defined criteria and the auditor's role.
Protect the clock. You have 135 seconds per question on average. Verify a doubtful point in your references, but do not turn every question into a research session.
