Stratified sampling is the most suitable technique for selecting customers for testing the IT support department's success in meeting service levels, as it involves dividing the population into distinct subgroups (strata) based on certain characteristics (in this case, customer size classification based on annual expenditures and service nature). This method ensures that each subgroup is adequately represented in the sample, providing more reliable and relevant results. References:

Inherent risk is the susceptibility of an activity to material error, fraud, or noncompliance before considering controls. For an AI program in development, the immediate and significant risk lies in copyright and intellectual property violations if the program captures and uses images owned by others. This risk exists inherently and could lead to lawsuits, reputational damage, and regulatory sanctions.
Options A and B represent possible outcomes but not immediate risks. Option D is a compliance issue but not immediate, as the regulation comes into force later. The most urgent and inherent risk is Option C, the unauthorized use of third-party content.

To confirm the existence of a specific vehicle selected from the fixed asset register, the best indirect evidence would be to compare the registered details of the vehicle with a date-stamped photograph. This method provides a verifiable form of evidence that the vehicle exists and matches the details recorded in the asset register. It ensures that the vehicle is still in possession of the organization and can be indirectly verified without the need for physical presence at an off-site location.

COSO Internal Control - Integrated Framework

In the five-attribute approach to documenting deficiencies, the attribute that answers the question "What should be in place?" is Criteria. Criteria represent the standards, measures, or expectations used in making an evaluation and/or verification (what should be). It defines what the process or control should achieve, serving as a benchmark against which the actual condition (what is) is compared. The criteria are essential for identifying deviations and determining the nature and significance of deficiencies.

Compliance assurance engagements evaluate the organization's adherence to laws, regulations, policies, or procedures. Assessing controls for consumer privacy aligns with compliance objectives, particularly under data protection regulations such as GDPR or CCPA. Option A refers to training, not assurance. Option C pertains to operational metrics, while Option D relates to financial reporting, not compliance. The IIA CIA syllabus identifies compliance engagements as critical for ensuring organizational alignment with external legal and regulatory expectations (Section III: Compliance Audits).
