Which characteristic distinguishes preMap hooks from postMap hooks?

• A. PreMap hooks can run calculations
• B. PostMap hooks can manipulate data post-mapping
• C. PreMap hooks validate data before it is sent
• D. PostMap hooks establish the mapping rules

Answer: (B)

The characteristic that distinguishes preMap hooks from postMap hooks is that postMap hooks can manipulate data after the mapping process has occurred. PostMap hooks are specifically designed to operate on the data once it has been mapped, allowing users to apply additional transformations or adjustments to the data before it is finally processed or sent to the destination system. This manipulation can include tasks such as cleaning data, formatting it for specific uses, or enriching it with additional information. PreMap hooks, on the other hand, are typically utilized before the mapping takes place. They focus on tasks such as validating incoming data or performing calculations that are necessary to prepare the data for mapping. Thus, postMap hooks have a distinct purpose related to post-processing, while preMap hooks are oriented toward preparing or checking data beforehand.
