Salesforce App Builder Practice Exam

Which of the following is true about Junction objects?

1. They are deleted when one associated master record is deleted.

2. They can be restored if both master records are deleted.

3. The first master-detail relationship is not always the primary relationship.

4. Deleting both associated master records permanently deletes the junction object.

The correct answer is: Deleting both associated master records permanently deletes the junction object.

The statement that deleting both associated master records permanently deletes the junction object is accurate. Junction objects are used in Salesforce to create many-to-many relationships between two other objects, and they function through master-detail relationships with each of the associated objects. When a junction object exists, it acts as a bridge between the two master records. In Salesforce, when both master records are deleted, the junction object is also deleted from the database, as it goes hand in hand with the integrity of the relationship it represents. This deletion is permanent, which means that once the master records are gone, the junction object cannot be recovered. This concept is crucial in understanding how relationships in Salesforce function and highlights the importance of managing master-detail relationships carefully, especially when dealing with junction objects. While other statements discuss the behavior of junction objects, they do not accurately reflect how deletions and relationships are managed in Salesforce.
