Free PECB ISO-IEC-27001-Lead-Auditor Exam Actual Questions

Note: Premium Questions for ISO-IEC-27001-Lead-Auditor were last updated On Mar. 09, 2026 (see below)

Question #1

Which one of the following options is the definition of the context of an organisation?

Reveal Solution Hide Solution
Correct Answer: C

The context of the organisation is the business environment in which the organisation operates and defines its information security management system (ISMS). It includes the internal and external factors and conditions that can influence the organisation's information security objectives, strategies, and policies. The context of the organisation helps the organisation to identify the scope, boundaries, and requirements of the ISMS, as well as the interested parties and their expectations. The context of the organisation is determined by considering both internal and external issues, such as the organisational structure, culture, values, mission, vision, objectives, strategies, resources, capabilities, processes, activities, products, services, markets, customers, competitors, suppliers, partners, regulators, laws, regulations, standards, guidelines, best practices, risks, opportunities, threats, vulnerabilities, etc. Reference: ISO 27001:2022 Clause 4 Context of the organization, ISO 27001 Requirement 4.1 -- Understanding the Context of the Organisation, ISO 27001 context of the organization -- How to define it - Advisera


Question #2

Scenario 9: Techmanic is a Belgian company founded in 1995 and currently operating in Brussels. It provides IT consultancy, software design, and hardware/software services, including deployment and maintenance. The company serves sectors like public services, finance, telecom, energy, healthcare, and education. As a customer-centered company, it prioritizes strong client relationships and leading security practices.

Techmanic has been ISO/IEC 27001 certified for a year and regards this certification with pride. During the certification audit, the auditor found some inconsistencies in its ISMS implementation. Since the observed situations did not affect the capability of its ISMS to achieve the intended results, Techmanic was certified after auditors followed up on the root cause analysis and corrective actions remotely During that year, the company added hosting to its list of services and requested to expand its certification scope to include that area The auditor in charge approved the request and notified Techmanic that the extension audit would be conducted during the surveillance audit

Techmanic underwent a surveillance audit to verify its iSMS's continued effectiveness and compliance with ISO/IEC 27001. The surveillance audit aimed to ensure that Techmanic's security practices, including the recent addition of hosting services, aligned seamlessly with the rigorous requirements of the certification

The auditor strategically utilized the findings from previous surveillance audit reports in the recertification activity with the purpose of replacing the need for additional recertification audits, specifically in the IT consultancy sector. Recognizing the value of continual improvement and learning from past assessments. Techmanic implemented a practice of reviewing previous surveillance audit reports. This proactive approach not only facilitated identifying and resolving potential nonconformities but also aimed to streamline the recertification process in the IT consultancy sector.

During the surveillance audit, several nonconformities were found. The ISMS continued to fulfill the ISO/IEC 27001*s requirements, but Techmanic failed to resolve the nonconformities related to the hosting services, as reported by its internal auditor. In addition, the internal audit report had several inconsistencies, which questioned the independence of the internal auditor during the audit of hosting services. Based on this, the extension certification was not granted. As a result. Techmanic requested a transfer to another certification body. In the meantime, the company released a statement to its clients stating that the ISO/IEC 27001 certification covers the IT services, as well as the hosting services.

Based on the scenario above, answer the following question:

Is the internal auditor responsible for following up on action plans resulting from external audits?

Reveal Solution Hide Solution
Correct Answer: A

Comprehensive and Detailed In-Depth

A . Correct Answer:

Internal auditors focus on internal audit nonconformities, while external auditors oversee external audit follow-ups.

B . Incorrect:

Minor nonconformities do not change the role of internal auditors.

C . Incorrect:

Internal auditors do not follow up on external audit findings---this is the certification body's responsibility.

Relevant Standard Reference:

ISO/IEC 27001:2022 Clause 9.2.2 (Internal Audit Responsibilities)


Question #3

Which is an example of a qualitative evidence?

Reveal Solution Hide Solution
Correct Answer: C

Qualitative evidence in an audit typically involves observations, interviews, and reviews that provide insights into the processes and compliance through subjective but informed assessments. An interview with information security personnel to validate compliance with the standard requirements is an example of qualitative evidence, where the quality and effectiveness of processes are assessed based on expert judgments rather than measurable metrics.


Question #4

In the context of a third-party certification audit, it is very important to have effective communication. Select an option that contains the correct answer about communication in an audit context.

Reveal Solution Hide Solution
Correct Answer: C

In the context of a third-party certification audit, it is very important to have effective communication between the audit team and the auditee. The formal communication channels, such as the names and contact details of the audit team members, the auditee representatives, the audit client and any other relevant parties, can be established during the opening meeting. This helps to ensure that the audit objectives, scope, criteria, methods, schedule and any other arrangements are clearly understood and agreed by all parties. It also facilitates the exchange of information, feedback, requests, concerns and complaints during the audit process. Reference: = ISO 19011:2022, clause 6.4.2; PECB Candidate Handbook ISO 27001 Lead Auditor, page 25.


Question #5

An organization is evaluating the materiality of different processes within its ISMS. It is assessing the direct expenses involved with personnel, third-party services, and general fees. Which factor of materiality is the company primarily considering?

Reveal Solution Hide Solution
Correct Answer: B

Comprehensive and Detailed In-Depth

B . Correct Answer:

The organization is focusing on direct costs associated with running specific processes.

'Personnel, third-party services, and general fees' refer to operational costs of specific processes, not overall business operations.

A . Incorrect:

Cost of operations refers to the total business expenses, not individual processes.

C . Incorrect:

Potential cost of errors relates to risk assessment and impact analysis, not direct expenses.
