How to Prepare for ISO-IEC-27001 Lead Implementer Exam?
Preparing for the ISO/IEC 27001 Lead Implementer exam requires both theoretical understanding and practical insight into ISMS implementation.
Start by developing a solid understanding of the ISO/IEC 27001 standard, including its clauses, Annex A controls, and the overall structure of an Information Security Management System. Candidates should be familiar with the full ISMS lifecycle, from initial planning and risk assessment to implementation, monitoring, and continual improvement.
Hands-on experience with ISMS implementation activities is highly recommended. This includes defining ISMS scope, conducting risk assessments, selecting and implementing security controls, developing policies and procedures, and supporting internal audits and management reviews.
In addition, reviewing PECB-aligned training materials, implementation frameworks, and real-world case scenarios helps reinforce how ISO/IEC 27001 requirements are applied in organizational contexts. Time management and familiarity with multiple-choice exam formats are also important for success in the exam.
Practice Questions for the ISO/IEC 27001 Lead Implementer Exam
Using practice questions is an effective way to assess exam readiness and reinforce key concepts covered in the ISO/IEC 27001 Lead Implementer exam.
Practice questions help candidates become familiar with the exam structure, question style, and difficulty level, while also identifying knowledge gaps across ISMS planning, implementation, monitoring, and improvement. High-quality practice questions are typically scenario-based and reflect real-world ISMS challenges rather than simple definitions.
Question#4
NeuroTrustMed is a leading medical technology company based in Seoul, South Korea. The company specializes in developing AI-assisted neuroimaging solutions used in early diagnosis and treatment planning for neurological disorders. As a data-intensive company handling sensitive patient health records and medical research data, NeuroTrustMed places a strong emphasis on cybersecurity and regulatory compliance. The company has maintained an ISO/IEC 27001-certified ISMS for the past three years. It continuously reviews and improves its ISMS to address emerging threats, support innovation in medical diagnostics, and maintain stakeholder trust. As part of its commitment to continual improvement, NeuroTrustMed actively tracks potential nonconformities, performs root-cause analyses, implements corrective and preventive actions, and ensures all changes are documented and aligned with the company’s strategic objectives. When a new data protection regulation came into effect affecting cross-regional data handling, the information security team conducted a gap assessment between current policies and the new regulation. Then, it updated relevant documentation and processes to meet compliance. Following these revisions, NeuroTrustMed updated the ISMS documentation and added a new entry in the improvement register. The register, maintained in the form of a structured spreadsheet, included a unique change number, a description of the update, and a high-priority classification due to legal compliance, the dates of initiation and completion, and the sign-off by the information security manager. Around the same period, during a scheduled management review, the information security team also identified a pattern of onboarding errors. While these had not resulted in any data breaches, they posed a risk of unauthorized access. In response, the onboarding procedure was revised and an automated verification step was added to ensure accuracy before access is granted. To understand the underlying cause, the team collected data on the provisioning process. They analyzed process logs, interviewed onboarding staff, and traced access errors back to a misconfigured step in the HR-to-IT handover workflow. The team validated this finding through test cases before implementing any changes. Once confirmed, the information security team documented the nonconformity in the ISMS log. The documentation included a description of the issue, impacted systems, affected users, and a brief risk assessment of potential consequences related to access management. Based on the scenario above, answer the following question.
Refer to scenario 10, is the composition of the certification decision committee acceptable?
A. Yes, as persons that make the decision for certification are different from those who carried out the audit.
B. No, the committee should have included only members from the audit team and no other experts that were not part of the audit
C. No, the committee must include one member from the audit team and other individuals working
for the certification body
Explanation:
In certification schemes for ISO/IEC 27001, it is a fundamental requirement that the certification decision is made by individuals who did not participate in the audit itself. This separation ensures objectivity, independence, and credibility of the certification decision.
While ISO/IEC 27001 defines ISMS requirements, the governance of certification decisions is addressed in ISO/IEC 17021-1, which requires that: The audit team does not make the certification decision
The decision is taken by competent personnel independent of the audit
Scenario 10 indicates that the certification decision committee consisted of individuals separate from the audit team, which satisfies this requirement.
Option B is incorrect because decision committees should not consist only of audit team members. Option C is incorrect because including audit team members in the decision-making body would compromise independence.
This structure also aligns with ISO/IEC 27006, which governs certification bodies auditing ISMSs and reinforces the need for impartial certification decisions.
