ISO-IEC-27001-Lead-Auditor Exam Essentials: Frequently Asked Questions

PECB Certified ISO/IEC 27001 Lead Auditor is an official PECB certification exam, listed under the code ISO-IEC-27001-Lead-Auditor. Clearing it earns the ISO 27001 certification, a Professional-level credential. It also ties into PECB ISO/IEC 27001 Lead Implementer, PECB ISO/IEC 27001 Foundation, which makes it a useful anchor for a longer certification plan. For employers, the value is simple: the vendor itself has verified what you know.

You will work through 80 questions in 180 minutes on the PECB Certified ISO/IEC 27001 Lead Auditor exam. The content is only half the battle; the clock is the other half. Train both at once: set the ValidDumps test engine to full timed mode, practice skipping and returning to stubborn items, and repeat until finishing with minutes to spare feels normal rather than lucky.

Passing PECB Certified ISO/IEC 27001 Lead Auditor requires 70%, and the official registration fee is USD 500. Remember that a retake bills the same USD 500 all over again, so winging it is the most expensive strategy on the table. A better approach: benchmark yourself with the ValidDumps practice tests first, and schedule the real exam only once your scores sit comfortably and consistently above the requirement.

Candidates should have a foundational understanding of ISO/IEC 27001 and audit principles. It is recommended (but not mandatory) to have completed the PECB ISO/IEC 27001 Lead Implementer training or equivalent experience.

PECB Certified ISO/IEC 27001 Lead Auditor Sample Questions:

Question #1

Scenario 3: Rebuildy is a construction company located in Bangkok.. Thailand, that specializes in designing, building, and maintaining residential buildings. To ensure the security of sensitive project data and client information, Rebuildy decided to implement an ISMS based on ISO/IEC 27001. This included a comprehensive understanding of information security risks, a defined continual improvement approach, and robust business solutions.
The ISMS implementation outcomes are presented below
*Information security is achieved by applying a set of security controls and establishing policies, processes, and procedures.
*Security controls are implemented based on risk assessment and aim to eliminate or reduce risks to an acceptable level.
*All processes ensure the continual improvement of the ISMS based on the plan-do-check-act (PDCA) model.
*The information security policy is part of a security manual drafted based on best security practices Therefore, it is not a stand-alone document.
*Information security roles and responsibilities have been clearly stated in every employees job description
*Management reviews of the ISMS are conducted at planned intervals.
Rebuildy applied for certification after two midterm management reviews and one annual internal audit Before the certification audit one of Rebuildy's former employees approached one of the audit team members to tell them that Rebuildy has several security problems that the company is trying to conceal. The former employee presented the documented evidence to the audit team member Electra, a key client of Rebuildy, also submitted evidence on the same issues, and the auditor determined to retain this evidence instead of the former employee's. The audit team member remained in contact with Electra until the audit was completed, discussing the nonconformities found during the audit. Electra provided additional evidence to support these findings.
At the beginning of the audit, the audit team interviewed the company's top management They discussed, among other things, the top management's commitment to the ISMS implementation. The evidence obtained from these discussions was documented in written confirmation, which was used to determine Rebuildy's conformity to several clauses of ISO/IEC 27001 The documented evidence obtained from Electra was attached to the audit report, along with the nonconformities report. Among others, the following nonconformities were detected:
*An instance of improper user access control settings was detected within the company's financial reporting system.
*A stand-alone information security policy has not been established. Instead, the company uses a security manual drafted based on best security practices.
After receiving these documents from the audit team, the team leader met Rebuildy's top management to present the audit findings. The audit team reported the findings related to the financial reporting system and the lack of a stand-alone information security policy. The top management expressed dissatisfaction with the findings and suggested that the audit team leader's conduct was unprofessional, implying they might request a replacement. Under pressure, the audit team leader decided to cooperate with top management to downplay the significance of the detected nonconformities. Consequently, the audit team leader adjusted the report to present a more favorable view, thus misrepresenting the true extent of Rebuildy's compliance issues.
Based on the scenario above, answer the following question:
Question:
Is it acceptable for the auditor to prioritize keeping the evidence provided by Electra over the evidence provided by the former employee?

  • A. No, both sources of evidence should be retained and evaluated equally
  • B. Yes, because evidence from a client is considered more reliable due to their independent status
  • C. No, because evidence from a former employee is always more reliable than that from a client

Question #3

Please match the following situations to the type of audit required.

Reveal Solution  Discussion  0

Correct Answer:


Explanation:
* Top management requests auditors from the organisation's compliance department to audit the production process in order to ensure the final product meets quality requirements = First-party audit
* Auditors from the buyer's organisation audit their raw material supplier to ensure the supply fulfils the order and contract = Second-party audit
* Auditors from an independent certification body conduct an audit of the organisation to verify conformity with an ISO Standard for certification purposes = Third-party audit
* The organisation has been audited against two management system standards in one audit = Combined audit According to the ISO/IEC 27001 standard, there are three main categories of audits: internal, external, and certification1. An internal audit, also known as a first-party audit, is an audit conducted by the organisation itself, or by an external party on its behalf, for management review and other internal purposes12. An external audit, also known as a second-party audit, is an audit conducted by a customer or other interested party on a supplier or contractor to verify compliance with contractual or other requirements12. A certification audit, also known as a third-party audit, is an audit conducted by an independent certification body to verify conformity with an ISO standard for certification purposes12. A combined audit is an audit where two or more management system standards are audited together3.

Question #4

Scenario 8
Trustingo has been providing banking and financial services in Estonia since 2010. The company has a network of 30 branches with over 100 ATMs nationwide. To meet strict data security and privacy regulations, Trustingo implemented an information security management system (ISMS) based on ISO/IEC 27001, ensuring better security, improved risk management, and compliance with legal requirements.
Nine months after the successful implementation of the ISMS, Trustingo decided to pursue certification for their ISMS based on ISO/IEC 27001 by an independent certification body. The certification audit included Trustingo's systems, processes, and technologies.
The audit team conducted the Stage 1 and Stage 2 audits jointly, and several nonconformities were detected.
The first nonconformity was related to Trustingo's labeling of information. The company had an information classification scheme but no information labeling procedure. As a result, documents requiring the same level of protection would be labeled differently.
The nonconformity also impacted media handling. The audit team used sampling and concluded that 50 of
200 removable media stored sensitive information mistakenly classified as confidential. According to the classification scheme, confidential information may be stored on removable media, whereas sensitive information is strictly prohibited.
The audit team drafted the nonconformity report and discussed conclusions with Trustingo's representatives.
Trustingo accepted the audit team leader's proposed solution and addressed the nonconformities by drafting an information labeling procedure and updating the removable media procedure.
Two weeks after audit completion, Trustingo submitted a general corrective action plan. Although it addressed the nonconformities, it lacked detailed action steps and system-specific impacts. As a result, Trustingo received an unfavorable certification recommendation.
Question
Which action in Scenario 8 is unacceptable in an external audit?

  • A. Stage 1 audit and Stage 2 audits were performed at the same time
  • B. The information labeling procedure was incomplete but marked as a minor nonconformity
  • C. The audit team leader proposed a solution for resolving the nonconformities, which is not allowed in external audits

Question #5

You are conducting an ISMS audit in the despatch department of an international logistics organisation that provides shipping services to large organisations including local hospitals and government offices. Parcels typically contain pharmaceutical products, biological samples, and documents such as passports and driving licences. You note that the company records show a very large number of returned items with causes including mis-addressed labels and, in 15% of company cases, two or more labels for different addresses for the one package. You are interviewing the Shipping Manager (SM).
You: Are items checked before being dispatched?
SH: Any obviously damaged items are removed by the duty staff before being dispatched, but the small profit margin makes it uneconomic to implement a formal checking process.
You: What action is taken when items are returned?
SM: Most of these contracts are relatively low value, therefore it has been decided that it is easier and more convenient to simply reprint the label and re-send individual parcels than it is to implement an investigation.
You raise a nonconformity. Referencing the scenario, which six of the following Appendix A controls would you expect the auditee to have implemented when you conduct the follow-up audit?

  • A. 5.13 Labelling of information
  • B. 5.3 Segregation of duties
  • C. 8.12 Data leakage protection
  • D. 5.32 Intellectual property rights
  • E. 5.11 Return of assets
  • F. 6.3 Information security awareness, education, and training
  • G. 7.4 Physical security monitoring
  • H. 8.3 Information access restriction
  • I. 6.4 Disciplinary process
  • J. 7.10 Storage media
  • K. 5.6 Contact with special interest groups
