Question

Difficulty: MediumStandard and Custom Object Management

A Salesforce administrator at a digital media agency is configuring the organization's data model and evaluating management rules for standard versus custom objects. Which two statements correctly describe the capabilities and characteristics of standard and custom objects in Salesforce? (Select 2)

  1. Standard objects provided by Salesforce cannot be deleted, whereas custom objects created by administrators can be deleted if no dependent components exist.Answer
  2. B
    Roll-up summary fields can be created on a custom object to aggregate data from child records connected through a standard lookup relationship.
  3. Standard fields automatically created on custom objects, such as Created By, Last Modified By, and Owner, cannot be deleted by an administrator.Answer
  4. D
    Deleting a parent record linked via a lookup relationship automatically deletes all associated child custom object records.

Answer

Standard objects provided by Salesforce cannot be deleted while custom objects can be deleted if free of dependencies, and standard system fields created on custom objects cannot be deleted by an administrator.
Standard objects delivered by Salesforce are permanent core schema components that cannot be deleted from an organization, whereas custom objects can be removed via Object Manager when no hard dependencies exist. Additionally, standard fields that Salesforce automatically attaches to custom objects (such as Created By, Last Modified By, and Owner) are required for platform auditability and cannot be deleted by administrators.

Step-by-Step Solution

1
Analyze object deletion rules for standard versus custom objects.
Standard objects are permanent platform components and cannot be deleted. Custom objects can be deleted when no dependent metadata or code references exist.
Differentiating object lifecycle boundaries ensures administrators understand object modification capabilities.
2
Evaluate standard field restrictions on custom objects.
System audit fields like Created By, Last Modified By, and Owner are created automatically on custom objects and cannot be deleted.
Salesforce mandates standard system fields for tracking record ownership and system governance.
3
Analyze relationship capabilities for roll-ups and record deletion.
Roll-up summary fields require a Master-Detail relationship, and cascading deletion happens under Master-Detail relationships, not default Lookup relationships.
Understanding the functional boundaries between Lookup and Master-Detail relationships prevents data model misconfigurations.
