Salesforce App Development


To eliminate redundant server call in Lightning Components, what 2 ways does Lightning Data Service eliminate redundant server calls in Lightning Components?

A. Lightning Data Services identifies requests that involve the same record data and sends a single shared data request that updates all relevant components.

B. Lightning Data Services allows each component within an app development to make independent, but concurrent, calls to perform CRUD operations on the same record data.

C. Lightning Data Services can be configured as a app development with simple Apex code.

D. Lightning Data Services acts as a publisher hub that notifies components of data changes.

Discussion: Use a single data request and update all components. And a publisher hub can be used to notify of data changes.
