Certified Information Systems Auditor (CISA) — Question 839

What is the BEST way to reduce the risk of inaccurate or misleading data proliferating through business intelligence systems?

Answer options

• A. Develop a metadata repository to store and access metadata.
• B. Implement data entry controls for new and existing applications.
• C. Implement a consistent database indexing strategy.
• D. Establish rules for converting data from one format to another.

Correct answer: B

Explanation

Implementing data entry controls ensures that only accurate and valid data is entered into the system, significantly reducing the risk of errors. While developing a metadata repository and indexing strategies are important for data management, they do not directly prevent inaccurate data entry. Establishing conversion rules is relevant but does not address the initial data input stage, which is crucial for maintaining data integrity.
