What will the destination file look like when deduplication is enabled on the phone number?

When deduplication is enabled on the phone number, the destination file will focus on ensuring that each phone number entry is unique and reflects the correct corresponding information. In this context, the correct answer represents the creation date, which is an important attribute that indicates when the data record was established.

This is significant because when deduplication processes are applied, other fields such as email, last name, or phone number might be filtered out in favor of maintaining only the most relevant and unique entries. The creation date serves as a crucial timestamp that can help determine which record to retain during deduplication, ensuring that only the most relevant or recent information is maintained in the destination file. This contributes to data integrity and cleanliness, which are essential in handling customer data efficiently.

In contrast, the other choices reflect specific data points that may not be relevant in a deduplication scenario, especially when multiple entries exist. Therefore, the creation date becomes a vital field that helps in managing how data is presented and ensures clarity regarding the origin of the data.
