Salesforce Marketers Marketing-Cloud-Email-Specialist Question # 2 Topic 1 Discussion

To automatically refresh a filtered data extension on a scheduled basis, a marketer should use a Filter Activity in Automation Studio. This activity allows you to apply a filter to a source data extension andsave the filtered results to a target data extension. By scheduling this activity within an automation, you can ensure that the filtered data extension is refreshed automatically at the desired frequency, such as daily before sending an email.
