What three methods are used to import data into a data extension?

The correct answer includes the API, Import Wizard, and Import Activity as methods to import data into a data extension.

The API (Application Programming Interface) allows for programmatic access to Salesforce Marketing Cloud, enabling users to import data from external systems directly into data extensions. This method is efficient for automating data transfers and handling large volumes of data without manual intervention.

The Import Wizard provides a user-friendly interface for manually uploading data files into data extensions. It guides users through the import process, allowing them to map fields and ensure data is accurately integrated.

Import Activity is used within Automation Studio to define a series of actions that import data into data extensions. This method allows for scheduled imports or automated workflows, integrating data management into broader marketing campaigns.

These three methods collectively support various use cases for importing data, from automated integrations via API to manual uploads with the Import Wizard, as well as scheduled imports through Import Activities. Each method plays a significant role in ensuring data integrity and usability within Salesforce Marketing Cloud.
