PECB ISO-IEC-27001-Lead-Auditor Exam With Confidence Using Practice Dumps

The correct answer is Previous audit experience within the audit scope, because judgement-based sampling relies heavily on the auditor’s professional judgment, knowledge, and experience. ISO 19011:2018 explicitly states that auditors may use judgmental (non-statistical) sampling when selecting audit samples, particularly when dealing with complex systems or limited audit time.

When applying judgement-based sampling, auditors consider factors such as areas with a history of nonconformities, previous audit findings, recurring weaknesses, and known high-risk processes. Prior audit experience within the same scope provides valuable insight into where problems are more likely to occur and where audit effort should be concentrated. This helps auditors select representative and meaningful samples that support reliable conclusions.

Option A is incorrect because monitoring activities prior to ISMS implementation may provide background context, but they are not a primary basis for judgement-based sampling in a certification audit. Option C is incorrect because the auditee’s general experience with management systems does not directly inform which specific records, processes, or controls should be sampled.

Judgement-based sampling is not random; it is risk-informed and experience-driven. Therefore, leveraging previous audit experience within the audit scope is the most appropriate and standards-aligned consideration.

Comprehensive and Detailed In-Depth Explanation:

C. Correct Answer:

The classification-based security approach aligns with ISO/IEC 27001:2022 Annex A Control A.5.12 (Classification of Information).

The organization is applying a security control in accordance with the classification policy, ensuring conformity to information security best practices.

A. Incorrect:

Nonconformity occurs when a process does not comply with ISO/IEC 27001 requirements. However, in this case, the classification system is correctly implemented.

B. Incorrect:

Anomaly refers to unexpected deviations in operations, but this is an intentional implementation.

A document review is a process of examining the documented information related to the management system before the on-site audit activities. The purpose of a document review is to: 12

Determine the conformity of the management system, as far as documented, with audit criteria, i.e., to check whether the documents are consistent, complete, and compliant with the requirements of ISO/IEC 27001 and any other applicable standards or regulations.

Gather information to support the on-site audit activities, i.e., to identify the scope, objectives, processes, controls, risks, and opportunities of the management system, and to plan the audit methods, techniques, and resources accordingly.

The other statements are not accurate, because:

A document review does not reveal or decide about the conformity or nonconformity of the management system as a whole, but only of the documented information. The conformity or nonconformity of the management system is determined by the on-site audit activities, which include interviews, observations, and tests12

A document review does not gather evidence or findings to support the audit report or process, but information to support the on-site audit activities. The evidence or findings are collected during the on-site audit activities, which are then documented and reported12

A document review does not detect any nonconformity of the management system, if documented, but determines the conformity of the documented information. The nonconformity of the management system is detected by the on-site audit activities, which evaluate the performance and effectiveness of the management system12

A document review does not identify information to support the audit plan, but gathers information to support the on-site audit activities. The audit plan is prepared before the document review, based on the audit scope, objectives, criteria, and program. The document review is part of the audit plan implementation12
