CISA - Certified Information Systems Auditor Practice Questions: Information Systems Acquisition, Development and Implementation Domain

Correct Answer: A

Explanation: The absence of a formal change management process significantly increases the risk of scope creep, as changes to the project can occur without proper evaluation and approval. While reduced quality, higher costs, and tracking issues are potential risks, scope creep directly results from unmanaged changes.

Correct Answer: A

Explanation: The primary risk associated with the waterfall model is the inability to handle changes in user requirements effectively (Option A). The waterfall model is a linear and sequential approach, making it difficult to incorporate changes once the project has progressed beyond the requirements phase. Excessive focus on user feedback (Option B) and lack of formal documentation (Option C) are not typical risks of the waterfall model. Managing large teams (Option D) is a general project management challenge, not specific to the waterfall approach.

Correct Answer: A

Explanation: Conducting a risk assessment to identify potential security threats should be the first step. This allows the organization to understand the specific security risks associated with the new system and tailor security requirements accordingly. Developing a security policy, reviewing existing policies, and implementing controls are subsequent steps that should be informed by the risk assessment findings.

Correct Answer: D

Explanation: The primary focus should be on confirming the software's compliance with applicable data protection regulations. This ensures that the software aligns with legal and organizational data privacy requirements. While data encryption, access controls, and vendor privacy policies are important components of data privacy, regulatory compliance is paramount.

Correct Answer: C

Explanation: In an agile development environment, the primary focus should be on the involvement of end users throughout the development process (Option C). Agile methodologies emphasize customer collaboration and iterative feedback to ensure the final product meets user needs. While documentation (Option A), timelines and budgets (Option B), and automated testing (Option D) are important, they are not as central to the agile approach as continuous user involvement.

Correct Answer: A

Explanation: The primary focus during a post-implementation review should be to assess whether the system meets the initial project objectives, as this directly impacts the system's ability to deliver expected benefits. While user training, cost management, and stakeholder satisfaction are important, they are secondary to ensuring that the system fulfills its intended purpose.

Correct Answer: B

Explanation: During the post-implementation phase, verifying that the system's performance metrics meet the defined benchmarks is critical. This ensures that the system operates as expected and delivers the anticipated benefits. While integration, training, and data migration are important, they are part of ensuring overall system performance.

Correct Answer: D

Explanation: The most critical factor to consider in the vendor selection process is whether the solution's functionality meets the business needs, ensuring alignment with the organization's strategic objectives. While cost, vendor reputation, and compatibility are important, they are secondary to ensuring the solution supports the organization's goals and delivers the required capabilities.

Correct Answer: B

Explanation: The primary focus should be on evaluating the service provider's compliance with industry standards, as this ensures they follow best practices and regulatory requirements. Option A is important for long-term viability but secondary to compliance. Option C is relevant but does not guarantee quality or compliance. Option D provides insights into customer satisfaction but not necessarily compliance or adherence to standards.

Correct Answer: C

Explanation: The primary focus during the pre-implementation audit should be on verifying that the system has undergone adequate user acceptance testing (UAT). UAT ensures that the system meets business requirements and functions correctly in real-world scenarios. While data migration, user training, and project documentation are important, UAT is critical for identifying any issues before the system goes live.
