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

The correct answer is A, because internal and external audits serve different but complementary purposes within an ISO/IEC 27001-based ISMS. Internal audits are conducted by or on behalf of the organization to regularly assess the effectiveness, conformity, and continual improvement of the ISMS. Their results help management identify weaknesses, risks, and opportunities for improvement before they become systemic issues.

ISO/IEC 27001 requires organizations to conduct internal audits at planned intervals to ensure the ISMS conforms to both internal requirements and the standard. These audits provide valuable input into management reviews, corrective actions, and readiness for external audits. In this way, internal audits act as an early warning and improvement mechanism.

External audits, conducted by an independent certification body, rely partly on the maturity demonstrated through internal audit outcomes. They verify whether the organization’s ISMS meets ISO/IEC 27001 requirements and whether internal audits are effective and properly implemented.

Option B is incorrect because internal audits are not passive reviews of external audit outputs; they are independent assessments with their own scope and objectives. Option C is incorrect because the roles are reversed: internal audits focus on ongoing internal improvement, while external audits focus on certification conformity.

Therefore, internal audits directly support and complement external audits by strengthening ISMS readiness and effectiveness.

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.

From Exact Extract:

1. Identification of potential impact

The scenario clearly states that the chatbot:

Sent random files to users

Encountered invalid inputs

Processed personally identifiable information (PII)

Operated in a live customer-facing environment

Sending random files to users represents a direct risk of unauthorized disclosure of information, which could include:

Customer records

Sensitive operational data

Personally identifiable information (PII)

This constitutes a customer privacy breach, which is a serious information security impact.

2. ISO/IEC 27001:2022 – Impact on confidentiality

Under ISO/IEC 27001:2022, one of the core objectives of an ISMS is to protect confidentiality, especially where PII is involved.

Clause 6.1.2 (Information security risk assessment) requires organizations to identify risks related to loss of confidentiality.

Clause 6.1.3 (Information security risk treatment) requires controls to be implemented where such risks exist.

A system that distributes random files creates a high-impact confidentiality risk.

3. ISO/IEC 27002:2022 – Privacy and PII protection

This scenario directly impacts Annex A control A.5.34 – Privacy and protection of PII, which requires organizations to:

Protect personal data against unauthorized access, disclosure, or misuse.

The chatbot’s behaviour violates the intent of this control and demonstrates a clear privacy impact.

4. Why the other options are incorrect

A. Temporary slowdown in internal system updatesThis is not supported by the scenario. There is no reference to internal system updates being affected.

C. Minor delays in customer service response timesWhile customer support was overwhelmed, the scenario describes a much more severe impact — uncontrolled file transmission and potential data exposure. This understates the risk.

Auditor Conclusion

The most significant and realistic impact arising from the chatbot issues is a breach of customer privacy due to the potential exposure of sensitive files. This aligns with ISO/IEC 27001’s focus on protecting confidentiality and PII.
