Question 1

Which of the following actions is NOT possible with a standard Lookup relationship that IS possible with a Master-Detail relationship?

Accepted Answer

Creating Roll-Up Summary fields on the parent

Answer

Roll-Up Summary fields can only be created on the master object of a Master-Detail relationship, not on Lookup relationship parents.

Question 2

In Salesforce, what does 'reparenting' refer to in the context of Master-Detail relationships?

Accepted Answer

Moving a child record to a different parent record

Answer

Reparenting is the ability to change a child record's parent in a Master-Detail relationship; it is disabled by default but can be enabled in the relationship settings.

Question 3

A developer needs to track which user last modified a record. Which field automatically provides this information?

Accepted Answer

LastModifiedById

Answer

The LastModifiedById standard field is automatically maintained by Salesforce and stores the ID of the user who last modified the record.

Question 4

When converting a Lookup relationship to a Master-Detail relationship, which prerequisite must be met?

Accepted Answer

All child records must already have a value in the lookup field

Answer

Because Master-Detail relationships require a parent value, all existing child records must have a non-null lookup value before the conversion can proceed.

Question 5

Answer

In Salesforce terminology, the object that sits between two related objects in a Many-to-Many relationship is officially called a Junction Object.
