Explanation:
Detection risk results when an IS auditor uses an inadequate test procedure and concludes that material
errors do not exist when errors actually exist.

Explanation:
The best way to handle obsolete magnetic tapes is to degauss them. This action leaves a very low residue of magnetic induction, essentially erasing the data from the tapes. Overwriting or erasing the tapes may cause magnetic errors but would not remove the data completely.
Initializing the tape labels would not remove the data that follows the label.

Explanation
The primary focus of a post-implementation review is to verify that user requirements have been met. User requirements are specifications that define what users need or expect from a system or service, such as functionality, usability, reliability, etc. User requirements are usually gathered and documented at the beginning of a project, and used as a basis for designing, developing, testing, and implementing a system or service. A post-implementation review is an evaluation that assesses whether a system or service meets its objectives and delivers its expected benefits after it has been implemented. The primary focus of a post-implementation review is to verify that user requirements have been met, as this can indicate whether the system or service satisfies the user needs and expectations, provides value and quality to the users, and supports the user goals and tasks. Enterprise architecture (EA) has been complied with is a possible focus of a post-implementation review, but it is not the primary one. EA is a framework that defines how an organization's business processes, information systems, and technology infrastructure are aligned and integrated to support its vision and strategy. EA has been complied with, as this can indicate whether the system or service fits with the organization's current and future state, and follows the organization's standards and principles. Acceptance testing has been properly executed is a possible focus of a post-implementation review, but it is not the primary one. Acceptance testing is a process that verifies whether a system or service meets the user requirements and expectations before it is accepted by the users or stakeholders. Acceptance testing has been properly executed, as this can indicate whether the system or service has been tested and validated by the users or stakeholders, and whether any issues or defects have been identified and resolved.
User access controls have been adequately designed is a possible focus of a post-implementation review, but it is not the primary one. User access controls are mechanisms that ensure that only authorized users can access or use a system or service, and prevent unauthorized access or use. User access controls have been adequately designed, as this can indicate whether the system or service has appropriate security and privacy measures in place, and whether any risks or threats have been mitigated.
