20+ practice questions focused on Information Systems Acquisition, Development and Implementation — one of the most tested topics on the Certified Information Systems Auditor CISA exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Information Systems Acquisition, Development and Implementation PracticeA company is replacing its legacy on-premises ERP system with a cloud-based SaaS solution. The project manager is concerned about data migration risks. Which of the following is the BEST approach to mitigate data integrity issues during migration?
Explanation: Option D is correct because running parallel processing allows the legacy and new SaaS systems to operate simultaneously, enabling real-time comparison of outputs. This approach directly validates data integrity by detecting discrepancies during migration, not after, which is critical for ERP systems where transactional accuracy is paramount.
An organization is developing a new customer portal. The development team wants to use an agile methodology. Which of the following is a key benefit of using agile for this project?
Explanation: Agile methodologies emphasize iterative development with continuous stakeholder feedback, which is critical for a customer portal where user needs evolve. This ensures the final product aligns with actual requirements, reducing rework and increasing satisfaction. Option A directly captures this core benefit.
During the user acceptance testing (UAT) phase of a new financial application, the business users report that the system calculates interest incorrectly for certain loan types. The project manager wants to fix this quickly. Which of the following is the BEST course of action?
Explanation: Option D is correct because in the UAT phase, any defect must be formally logged and subjected to impact analysis before a fix is approved. This ensures that the proposed change does not introduce new risks, break other functionality, or violate regulatory compliance—critical for a financial application handling interest calculations. Skipping this process could lead to cascading failures or audit findings.
An IT auditor is reviewing the system development life cycle (SDLC) process for a critical application. Which of the following findings would be of MOST concern?
Explanation: Developers having direct production database access violates the principle of segregation of duties and poses a significant risk of unauthorized data modification, deletion, or exfiltration. In a well-controlled SDLC, production access should be restricted to operations or DBA teams, with changes promoted through automated deployment pipelines. This finding directly undermines data integrity and confidentiality controls.
When implementing a commercial off-the-shelf (COTS) software package, which of the following is the MOST important activity to ensure the software meets business requirements?
Explanation: Performing a gap analysis is the most important activity because it systematically maps each business requirement against the COTS software's delivered features, identifying any shortfalls that must be addressed through configuration, customization, or process adaptation. Without this structured comparison, the organization risks deploying software that fails to support critical business processes, leading to costly rework or project failure.
