Salesforce recommends using declarative tools like Flow to automate updates to related records. In this use case, a Record-Triggered Flow can be created on the Account object. When the billing address of the HQ account is updated, the flow can identify and update all related branch accounts (using a defined relationship such as a lookup or parent-child).

B. Correct — Create a Record-Triggered Flow on Account that checks for changes to the billing address and updates child records accordingly.

Incorrect Options:

A. Dataloader is a manual tool, not a real-time automation solution.

C. Apex can solve this but is not required for such declarative use cases.

D. A formula field only displays data; it does not trigger updates.

Reference Extracts from Salesforce Process Automation Study Guide:

“Use Record-Triggered Flows to update related records based on changes to a parent record.”

“Flows can be configured to loop through child records and apply updates when specific field values change.”
