Question

Difficulty: MediumStandard and Custom Object Management

A Salesforce administrator at a renewable energy company is setting up a new data model to manage customer service agreements. The design involves establishing relationships between the standard Account object and a newly created custom object named Solar_Tracker__c. Which TWO statements correctly describe the capabilities and limitations of standard objects versus custom objects in Salesforce? (Select 2)

  1. Standard objects can act as the master side in a master-detail relationship, but cannot be the detail child object in a master-detail relationship with a custom object.Answer
  2. Custom objects can be deleted from an organization, whereas standard objects cannot be deleted.Answer
  3. C
    Roll-up summary fields can be created on the standard Account object to aggregate data from Solar_Tracker__c records connected via a lookup relationship.
  4. D
    Deleting a child detail record automatically deletes the associated parent master Account record.

Answer

Standard objects can serve as the master parent but cannot be the detail child object in a master-detail relationship with a custom object, and custom objects can be deleted whereas standard objects cannot be deleted.
Standard objects can serve as the master parent object in a master-detail relationship with a custom detail object, but standard objects can never be on the detail side of a master-detail relationship. Additionally, custom objects can be deleted from an org if they are not referenced elsewhere, while standard objects cannot be deleted.

Step-by-Step Solution

1
Evaluate relationship hierarchy constraints between standard and custom objects.
Standard objects can exist on the master side of a master-detail relationship with custom child objects, but a standard object cannot be made a child detail object to a custom master object.
Salesforce architecture restricts standard objects from being dependent detail records under custom objects.
2
Evaluate deletion lifecycle rules for standard vs custom objects.
Custom objects can be deleted when no longer required, but standard objects cannot be deleted from an org.
Standard objects are foundational components of the Salesforce core application.
3
Verify roll-up summary field prerequisites and cascading deletion behavior.
Roll-up summaries require master-detail relationships, not lookups. Deleting detail records does not delete parent master records.
Roll-up calculations depend on master-detail relationship coupling, and deletion cascades top-down, not bottom-up.
