Certified Information Systems Auditor (CISA) — Question 1403

Which of the following is the BEST indication of the completeness of interface control documents used for the development of a new application?

Answer options

• A. Failed interface data transfers prevent subsequent processes.
• B. All documents have been reviewed by end users.
• C. Both successful and failed interface data transfers are recorded.
• D. All inputs and outputs for potential actions are included.

Correct answer: D

Explanation

The correct answer, D, is essential because it ensures that all potential actions are considered, indicating thorough documentation. Options A and C focus on data transfer outcomes, which do not directly reflect the completeness of the documents. Option B, while important, does not guarantee that all necessary information is included in the documents.
