| Duration | 3 hours / 180 minutes |

| Question style | Stand-alone and scenario-based |

Written to the current PECB outline
The question bank targets ISO/IEC 27001:2022 and PECB's current seven-domain Lead Auditor structure. It covers the ISMS requirements, audit principles, preparation, fieldwork, conclusions and audit-program management.
The questions are original. They are written as auditor decisions and evidence problems rather than clause-number trivia, with three plausible options and one best answer.
The actual PECB exam is open book. These tests keep the same 80-question, 180-minute frame so you can practise the judgment and pacing before exam day.
Eighty questions under the full 180-minute clock
The difficult part is rarely recalling a definition. It is deciding what the auditor should do next when the evidence is incomplete, the criterion is disputed, or two answers both sound defensible.
How it is built
- 80 questions in 180 minutes
- Raw percentage score with 70% as the pass line
- 13 / 8 / 14 / 12 / 18 / 7 / 8 domain distribution
- Three answer options, exactly one correct
- Scenario-led audit judgment throughout the bank
- Same blueprint structure across all ten tests
Under the clock
- Countdown with automatic submission at zero
- Flag questions and come back to them
- Skip, revisit and change answers
- Final review before submitting
- Question order changes between attempts
- Progress is saved if the tab closes
What comes back
- Raw percentage score against the 70% pass line
- Breakdown across all seven competency domains
- Full review of your answer and the correct answer
- An explanation on every question
- PDF report and emailed result
- Past attempts kept in your dashboard
The evidence matters more than the adjective
This question comes from the current PECB Lead Auditor bank. It tests whether the finding stays tied to objective evidence instead of drifting into personal judgment.
An auditor drafts a finding that names an individual administrator as “careless” even though the objective evidence is that a required peer approval was absent for three sampled changes. What should the auditor change FIRST?
- AState the verified condition, sample context, and unmet criterion without assigning unsupported personal blame or character judgments
- BKeep the personal characterization because naming the presumed cause makes the finding stronger than describing objective evidence
- CRemove the sample evidence because findings should discuss individual behavior rather than the requirement that was not met
Why A
An audit finding should be evidence-based and traceable to criteria. Personal blame or character judgments are unnecessary unless directly relevant and objectively supported. The finding should say what was observed, the sample context, and which requirement was not met.
Why B looks tempting
Calling someone “careless” can sound decisive, but it moves beyond the verified evidence. The audit has evidence of missing peer approval, not evidence supporting a character judgment about the administrator.
Every test follows PECB's 80-question distribution
Conducting an ISO/IEC 27001 audit is the largest domain at 22.5%. The fixed question counts below add to 80 and match PECB's current handbook.
| Competency domain | PECB weight | Questions per test |

| 1. Fundamental principles and concepts of an information security management system (ISMS) | 16.25% | 13 |
| 2. Information security management system (ISMS) and ISO/IEC 27001 requirements | 10% | 8 |
| 3. Fundamental audit concepts and principles | 17.5% | 14 |
| 4. Preparing an ISO/IEC 27001 audit | 15% | 12 |
| 5. Conducting an ISO/IEC 27001 audit | 22.5% | 18 |
| 6. Closing an ISO/IEC 27001 audit | 8.75% | 7 |
| 7. Managing an ISO/IEC 27001 audit program | 10% | 8 |
