Salesforce Certified Marketing Cloud Consultant — Question 88

A customer provides a file containing only new and updated subscriber records exported from its marketing database.
✑ The file will be uploaded to the customer's Enhanced FTP automatically at 3 a.m. daily.
✑ The customer requires that the import completes prior to 4 a.m.
✑ On average, the file will contain about two million rows of data each day.
Based on the customer's requirements and recommended best practices, how should the daily file be imported?

Answer options

Correct answer: C

Explanation

The correct answer is C because importing into a data extension using the 'add and update' method allows for efficient handling of large datasets, ensuring that new and updated records are processed correctly without duplicates. Options A and B are less optimal as they involve lists, which may not handle large volumes as effectively, and option D would overwrite existing data, which is not necessary given the customer's requirement to only update records.
