Suggested answer: A

Explanation:

The best way to reduce the risk of inaccurate or misleading data proliferating through business intelligence systems is to establish rules for converting data from one format to another, because this ensures that the data quality and integrity are maintained throughout the data transformation process.Data conversion rules define the standards, procedures, and methods for transforming data from different sources and formats into a common format and structure that can be used by the business intelligence systems12.Implementing data entry controls for new and existing applications, implementing a consistent database indexing strategy, and developing a metadata repository to store and access metadata are not the best ways to reduce the risk of inaccurate or misleading data proliferating through business intelligence systems, because they do not address the issue of data conversion, which is a critical step in the data integration process for business intelligence systems.Reference:1: CISA Review Manual (Digital Version), Chapter 4, Section 4.3.32: CISA Online Review Course, Module 4, Lesson 3
