Final answer:
The Change Data Value flow actions in Marketo are not best used for cleaning up duplicate records as they do not merge or remove redundant records, which is essential in deduplication processes.
Step-by-step explanation:
The question is asking which of the following is NOT a good use of Change Data Value flow actions in Marketo:
- Correction of existing data
- Normalization of data
- Cleanup of duplicate records
- Mass updates to records
The correct answer is C. Cleanup of duplicate records. Change Data Value actions in Marketo are designed to modify the data within individual records. They are useful for correcting, normalizing, or updating data in bulk. However, when dealing with duplicate records, simply changing data values will not resolve the issue of duplicates, as it does not actually merge or remove the redundant records. Instead, a dedicated process for deduplication should be utilized that can merge or delete duplicate entries properly.
