Changed ISO-IEC-27001-Foundation Exam Questions

Clause 4.3 (Determining the scope of the ISMS) requires consideration of:

“the external and internal issues referred to in 4.1; the requirements referred to in 4.2; and interfaces and dependencies between activities performed by the organization, and those that are performed by other organizations.”

This confirms that dependencies between activities are a required factor when defining scope. Options B (quality levels), C (lessons learned), and D (regular activities for improvement) are not scope requirements, though they may be relevant in planning or improvement processes.

Thus, the verified answer is A: Dependencies between activities performed by the organization.

Clause 6.1.2 (Information security risk assessment) requires organizations to “define and apply an information security risk assessment process that… establishes and maintains information security risk criteria, including criteria for accepting risk.”

This means that acceptable levels of risk (risk acceptance criteria) must be explicitly defined. These criteria ensure consistent decision-making when evaluating whether identified risks need further treatment or can be tolerated.

Option A is incorrect because exclusions relate to the ISMS scope (Clause 4.3), not risk assessment planning. Option B is not a requirement; effectiveness of risk assessment methods is not required to be measured, though methods must be applied consistently. Option D is false—the standard clearly specifies required elements for risk assessment.

Thus, the correct answer isC: The criteria for acceptable levels of risk.

The benefits of implementing an ISMS under ISO/IEC 27001 are well established. Clause 0.1 (General) explains that an ISMS provides asystematic approach to managing sensitive informationand “preserves confidentiality, integrity, and availability of information by applying a risk management process and gives confidence to interested parties that risks are adequately managed.”

Option A is correct as a benefit, since trust and confidence from stakeholders is an outcome of compliance. Option C is also a benefit, since controls are chosen and tailored based on organizational context and risk assessment (Clause 6.1.3). Option D reflects another real benefit—reducing the probability and/or impact of incidents through effective risk management.

However,staff qualifications (option B)are not guaranteed benefits of implementing an ISMS. While training and competence (Clause 7.2) are required, the standard does not require or provide ISO/IEC 27001 Foundation-level certification for staff. That is an external training/certification scheme, not an ISMS outcome.

Therefore, the benefitNOT relevantto implementing ISO/IEC 27001 isB.
