Certified Information Systems Auditor (CISA) — Question 1141

An IS auditor reviewing an organization’s IT systems finds that the organization frequently purchases systems that are incompatible with the technologies already in the organization. Which of the following is the MOST likely reason?

Answer options

• A. Lack of enterprise architecture (EA)
• B. Outdated enterprise resource planning (ERP) system
• C. Ineffective risk management policy
• D. Lack of a maturity model

Correct answer: A

Explanation

The correct answer is A because a lack of enterprise architecture can lead to disjointed technology purchases that do not align with existing systems. The other options, while they may indicate issues within the organization, do not directly explain the frequent incompatibility of new systems with current technologies.
