CGEIT Question #122: Real Exam Question with Answer & Explanation

Question

An enterprise plans to implement a business intelligence (Bl) tool with data sources from various enterprise applications. Which of the following is the GREATEST challenge to implementation?

Options

• AInterface issues between enterprise and Bl applications
• BLarge volumes of data fed from enterprise applications
• CThe need for staff to be trained on the new Bl tool
• DData definition and mapping sources from applications

Explanation

The greatest challenge in implementing a BI tool with diverse data sources is reconciling the inconsistencies and lack of standardization in data definitions and mappings across different applications.

Common mistakes.

• A. Interface issues can be challenging, but modern integration tools and APIs are designed to mitigate these, often making data content and meaning a larger hurdle than connectivity.
• B. While large data volumes pose technical challenges for storage and processing, current BI tools and data platforms are specifically designed to handle big data; the quality and consistency of the data itself are often a more critical and complex issue.
• C. Staff training is a common implementation task for any new tool; while important, it's typically less complex and costly than resolving fundamental data quality and consistency problems.
