DreamHouse Realty wants to make sure an Opportunity has a field, Expected_Close_Date_c, populated before it...

omprehensive and Detailed Explanation with all Platform App Builder documents: =

The correct answer is C. Validation Rule.

DreamHouse Realty needs to prevent an Opportunity from entering the Qualified stage unless Expected_Close_Date__c is populated. A validation rule is the correct feature because validation rules check whether record data meets defined requirements before the record can be saved. Salesforce also provides examples of validation rules used to control Opportunity stage changes.

Example formula:

AND(

ISPICKVAL(StageName, " Qualified " ),

ISBLANK(Expected_Close_Date__c)

)

A is incorrect because record types do not enforce this conditional requirement by themselves.

B is incorrect because page layouts cannot reliably enforce conditional required fields by stage.

D is incorrect because Activity History does not validate data entry.
