IBM Planning Analytics V2.0 Developer — Question 28

Which statement describes why more than one collection would need to be created in IBM Watson Discovery service?

Answer options

• A. It is better to have multiple small collections than one big collection
• B. The first collection uses default configuration for testing and additional collections are needed for custom configurations
• C. To keep similar file types in their respective collections
• D. The data may be so different that it doesn't make sense for it all to be queried at once

Correct answer: D

Explanation

The correct answer, D, highlights that when data varies greatly, it is impractical to query it all at once. Options A, B, and C may have their merits, but they do not directly address the necessity of creating multiple collections based on the diversity of data.
