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 PracticeWhich THREE of the following are essential elements of an emergency change request? (Select three.)
Explanation: Option A (Test plan) is correct because an emergency change still requires a documented test plan, even if abbreviated, to verify the change works and does not introduce new faults before or immediately after implementation. Option D (Rollback plan) is correct because emergency changes carry elevated risk, so a defined rollback (back-out) plan is essential to restore the previous known-good state if the change fails. Option E (Justification for emergency) is correct because the request must document why the change cannot wait for the normal change management cycle, legitimizing the use of the emergency process. Option B (Impact analysis) is not among the marked correct answers, and Option C (Pre-approval from CAB) is not required for emergency changes since they typically receive expedited or retrospective approval rather than prior CAB authorization.
An IS auditor is reviewing a vendor's SOC 2 report as part of a systems acquisition. Which TWO aspects should the auditor verify to ensure the report is reliable?
Explanation: Option A is correct because a SOC 2 report is a point-in-time attestation, and the AICPA guidance expects the report to cover a recent period (typically within the last 12 months) so that the auditor can rely on the tested controls as current; an older report may not reflect the vendor's present control environment. Option C is correct because SOC 2 reports must be issued by an independent, licensed CPA firm under AT-C 205 (formerly SSAE 18), and independence is essential for the report's credibility and for the auditor to rely on the opinion. Options B, D, and E are not the reliability criteria: a business continuity plan description, a customer list, and internal control objectives may appear in or accompany the report but do not by themselves establish that the report is trustworthy or current.
An organization is considering replacing its legacy financial system with a new ERP solution. Which of the following is the PRIMARY advantage of purchasing a commercial off-the-shelf (COTS) ERP package over building a custom system?
Explanation: The primary advantage of a COTS ERP package over a custom-built system is faster implementation, because the software is pre-built, pre-tested, and comes with vendor-provided functionality, documentation, and support. Organizations configure rather than code, dramatically shortening time-to-value. This speed is the most direct and universally applicable benefit.
During a spiral model SDLC project, an IS auditor is reviewing risk assessment documentation. Which of the following would be the GREATEST concern?
Explanation: The spiral model is risk-driven; failure to identify critical risks undermines the methodology and could lead to project failure.
An organization is deciding between developing a custom application and purchasing a commercial off-the-shelf (COTS) product. The project manager favors a COTS solution because it offers faster deployment. Which of the following is the MOST important consideration for the IS auditor to evaluate in this build vs. buy decision?
Explanation: Vendor dependency is a critical risk in COTS acquisitions. The organization may become reliant on the vendor for updates, support, and customizations, which can affect long-term flexibility and costs.
