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

The purpose of a follow-up audit is to verify the completion and effectiveness of corrective actions taken by the auditee in response to the nonconformities identified in a previous audit1. A follow-up audit is a type of audit that is conducted after an initial audit, and it focuses on the specific areas where nonconformities were found and corrective actions were agreed upon2. A follow-up audit can be conducted as a separate audit or as part of a scheduled audit, depending on the nature and severity of the nonconformities and the audit programme objectives3.

The other options are not the purpose of a follow-up audit, but rather the purpose of other types of audits. For example:

•Option A is the purpose of a performance audit, which is a type of audit that evaluates the effectiveness of the management system in achieving its intended results4.

•Option B is the purpose of a compliance audit, which is a type of audit that verifies the conformity of the management system with the specified requirements, such as the ISMS objectives5.

•Option C is the purpose of a process audit, which is a type of audit that examines the inputs, activities, outputs, and interactions of a specific process within the management system, such as the risk treatment process.

One possible way to complete the sentence is:

“When reviewing the effectiveness of action taken in response to a nonconformity, an auditor seeks evidence of change that will prevent recurrence of the issue.”

According to ISO/IEC 27001:2022, clause 10.1, the organization shall continually improve the suitability, adequacy, and effectiveness of the ISMS by evaluating the performance and the effectiveness of the ISMS, ensuring that the policy and objectives are aligned with the strategic direction of the organization, and taking actions to achieve the intended outcomes of the ISMS. One of the ways to achieve continual improvement is to identify and correct nonconformities and take actions to eliminate their causes and prevent their recurrence. Therefore, when reviewing the effectiveness of the corrective actions, an auditor should look for evidence that the organization has analyzed the root cause of the nonconformity, implemented appropriate changes to the ISMS, and verified that the changes have resulted in the desired improvement and prevented the recurrence of the issue.

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.
