Explanation
This is an example of a social engineering threat, which is a type of human threat that involves manipulating or deceiving people into revealing confidential information, performing unauthorized actions, or compromising the security of information assets. Social engineering techniques can exploit the psychological, emotional, or behavioral vulnerabilities of people, such as trust, curiosity, fear, or greed. A person claiming to be from the Helpdesk and asking for your password is trying to trick you into giving away your credentials, which can be used to access your account or system without your authorization. Therefore, the correct answer is C. References: ISO/IEC 27000:2022, clause 3.25; What is Social Engineering? | Definition and Examples.

According to ISO/IEC 17021-1:2015, which specifies the requirements for bodies providing audit and certification of management systems, clause 9.4.9 requires the certification body to make a certification decision based on the information obtained during the audit and any other relevant information1. The certification body should also consider the effectiveness of the corrective actions taken by the auditee to address any nonconformities identified during the audit1. Therefore, when making a recommendation to the audit programme manager, an ISMS auditor should consider the nature and severity of the nonconformities and the proposed corrective actions.
Based on the scenario above, the auditor should recommend certification after their approval of the proposed corrective action plan and recommend that the findings can be closed out at a surveillance audit in 1 year. The auditor should provide the following justification for their recommendation:
Justification: This recommendation is appropriate because it reflects the fact that the auditee has only two minor nonconformities and one opportunity for improvement, which do not indicate a significant or systemic failure of their ISMS. A minor nonconformity is defined as a failure to achieve one or more requirements of ISO/IEC 27001:2022 or a situation which raises significant doubt about the ability of an ISMS process to achieve its intended output, but does not affect its overall effectiveness or conformity2. An opportunity for improvement is defined as a suggestion for improvement beyond what is required by ISO/IEC 27001:20222. Therefore, these findings do not prevent or preclude certification, as long as they are addressed by appropriate corrective actions within a reasonable time frame. The auditor should approve the proposed corrective action plan before recommending certification, to ensure that it is realistic, achievable, and effective. The auditor should also recommend that the findings can be closed out at a surveillance audit in 1 year, to verify that the corrective actions have been implemented and are working as intended.
The other options are not valid recommendations for the audit programme manager, as they are either too lenient or too strict for the given scenario. For example:
Recommend certification immediately: This option is not valid because it implies that the auditor ignores or accepts the nonconformities, which is contrary to the audit principles and objectives of ISO
19011:20182, which provides guidelines for auditing management systems. It also contradicts the requirement of ISO/IEC 17021-1:20151, which requires the certification body to consider the effectiveness of the corrective actions taken by the auditee before making a certification decision.
Recommend that a full scope re-audit is required within 6 months: This option is not valid because it implies that the auditor overreacts or exaggerates the nonconformities, which is contrary to the audit principles and objectives of ISO 19011:20182. It also contradicts the requirement of ISO/IEC
17021-1:20151, which requires the certification body to determine whether a re-audit is necessary based on the nature and extent of nonconformities and other relevant factors. A full scope re-audit is usually reserved for major nonconformities or multiple minor nonconformities that indicate a serious or widespread failure of an ISMS.
Recommend that an unannounced audit is carried out at a future date: This option is not valid because it implies that the auditor distrusts or doubts the auditee's commitment or capability to implement corrective actions, which is contrary to the audit principles and objectives of ISO 19011:20182. It also contradicts the requirement of ISO/IEC 17021-1:20151, which requires the certification body to conduct unannounced audits only under certain conditions, such as when there are indications of serious problems with an ISMS or when required by sector-specific schemes.
Recommend that a partial audit is required within 3 months: This option is not valid because it implies that the auditor imposes or prescribes a specific time frame or scope for verifying corrective actions, which is contrary to the audit principles and objectives of ISO 19011:20182. It also contradicts the requirement of ISO/IEC 17021-1:20151, which requires the certification body to determine whether a partial audit is necessary based on the nature and extent of nonconformities and other relevant factors. A partial audit may be appropriate for minor nonconformities, but the time frame and scope should be agreed upon with the auditee and based on the proposed corrective action plan.

According to ISO 19011:2018, which provides guidelines for auditing management systems, a sampling plan is a method for selecting a representative subset of the audit evidence from a defined population1. A sampling plan can have several advantages for the audit, such as providing a suitable understanding of the ISMS by covering its key processes, activities, and controls; implementing the audit plan efficiently by optimizing the use of time and resources; and giving confidence in the audit results by ensuring that the sample is sufficient, reliable, and unbiased1. Therefore, these three options are examples of advantages of using a sampling plan for the audit. The other options are not advantages, but rather disadvantages or risks of using a sampling plan. For example, overruling the auditor's instincts may lead to missing important evidence or issues that are not covered by the sampling plan; using the same plan for consecutive audits may reduce the effectiveness and validity of the audit results; and missing key issues may result from an inadequate or inappropriate sampling plan1.

Explanation
A physical security measure is a measure that protects information and information processing facilities from physical threats and hazards, such as fire, flood, earthquake, theft, vandalism, etc. Physical security measures include locks, alarms, fences, cameras, fire extinguishers, ventilation systems, etc. The computer room is protected by a pass reader that only allows authorized personnel from the System Management department to access it. This is an example of a physical security measure, because it prevents unauthorized physical access to the computer room and its contents. ISO/IEC 27001:2022 requires the organization to implement physical and environmental security controls to prevent unauthorized physical access, damage and interference to the organization's information and information processing facilities (see clause A.11).
