Form or Form Handler? I need data de-duplication in the CRM.
A . Form
B . Form Handler

Answer: A

Explanation:

Marketing Cloud Account Engagement forms are the best option if you need data de-duplication in

the CRM, such as Salesforce. Marketing Cloud Account Engagement forms can automatically match

and update existing records in the CRM based on the email address or other unique identifiers4. Marketing Cloud Account Engagement forms can also create new records in the CRM if

the prospect does not exist yet4. Form handlers, on the other hand, do not have this functionality, and may create duplicate records in the CRM if the prospect already exists
