The correct answer is D. The CRM Connector allows standard fields to stream into Data Cloud in real time. This means that any changes to the standard fields in the CRM data source are reflected in Data Cloud almost instantly, without waiting for the next scheduled synchronization. This feature enables Data Cloud to have the most up-to-date and accurate CRM data for segmentation and activation1.

The other options are incorrect for the following reasons:

A. CRM data can be manually refreshed at any time by clicking the Refresh button on the data stream detail page2. This option is false.

B. The CRM Connector’s synchronization times can be customized to up to 60-minute intervals, not 15-minute intervals3. This option is false.

C. Formula fields are not refreshed at regular sync intervals, but only at the next full refresh4. A full refresh is a complete data ingestion process that occurs once every 24 hours or when manually triggered. This option is false.
