What type of automation could be the driver of a data import setup that activates when a file is placed on the SFTP?

The correct answer is File Drop Automation. This specific type of automation is designed to trigger when a file is placed in a designated location, such as an SFTP (Secure File Transfer Protocol) server. When an event occurs—such as a file being uploaded—File Drop Automation can initiate processes such as importing data into Marketing Cloud.

File Drop Automation is particularly useful for handling situations where data needs to be processed in real-time or on an ad-hoc basis based on file availability. This gives marketers the flexibility to streamline data imports as part of a larger automation strategy without manual intervention.

In contrast, Scheduled Automation typically runs at predefined intervals, regardless of whether new files are present. API Event Automation is focused on instant actions that occur as a result of API calls, and Data Event Automation usually triggers processes based on changes or updates within data extensions, rather than through file uploads. Each of these options serves different purposes in automation workflows, making File Drop Automation the most appropriate choice for the scenario described.
