How can a filtered data extension be refreshed on a recurring basis?

The correct choice involves creating a Filter Activity that selects the Pref1-Tech Data Filter and incorporating that activity into an Automation. This approach is effective because the Filter Activity allows for dynamic segmentation of data based on defined criteria and can be scheduled to run regularly within an Automation. By doing this, the filtered data extension is updated according to the predetermined schedule, ensuring that it always contains the most current data that meets the specified conditions.

This method utilizes the capabilities of Automation Studio in Salesforce Marketing Cloud, where you can easily control the timing and frequency of data refreshes. Additionally, using a Filter Activity gives you the flexibility to adjust the filtering criteria as needed without needing to recreate the entire filtered data extension.

Other options might suggest starting a filtered Data Extension Activity or simply adding a filter to the Automation without detailing how to effectively refresh the data. These methods may not provide the same level of flexibility or automation as the selected approach, which is focused explicitly on ensuring that the data within the filtered data extension is refreshed consistently in accordance with specific segmentation rules.
