IBM PureData System for Analytics V7.0 — Question 4

You have a data source which provides many fields needed for data scoring. Some of these fields are not needed after the scoring is complete for the rest of the stream to operate.
Which node should be used to remove these fields?

Answer options

• A. Filter node
• B. Select node
• C. Sample Node
• D. Type node

Correct answer: B

Explanation

The Select node is designed specifically to include or exclude certain fields from the data stream, making it the correct choice for removing unnecessary fields. The Filter node is used to filter rows based on conditions, the Sample Node selects a subset of data, and the Type node is utilized for type conversion, none of which are suitable for field removal.
