What happens to junction object records when both associated master records are deleted?

1. They're retained in the Recycle Bin.

2. They're permanently deleted and cannot be restored.

3. They must be manually deleted by the user.

4. They are archived automatically.

The correct answer is: They're permanently deleted and cannot be restored.

When both associated master records of a junction object are deleted, the records of the junction object are permanently deleted and cannot be restored. This outcome is due to the nature of how junction objects function in Salesforce; they play a critical role in establishing many-to-many relationships between two objects. When the master detail relationship is in place, the deletion of a parent or master record leads to the cascading deletion of its child records, including those associated with junction objects. In this case, since both masters are deleted, the junction object records lose their context and become irrecoverable immediately, highlighting the importance of understanding data relationships and the implications of record deletions in Salesforce. This mechanism is designed to maintain data integrity, ensuring that orphaned junction records do not exist without their associated parent records. In practice, this means that it's essential for administrators and users to carefully manage and assess the impact of deletions within these relationships.
