Salesforce Certified Platform App Builder — Question 448

Ursa Major Solar wants to convert the relationship between Galaxy and Star from a lookup relationship to a master-detail relationship so each Galaxy record can be equipped with a roll-up summary count of Star records.
Which two considerations should be made? (Choose two.)

Answer options

• A. The Star object has fewer than two existing master-detail relationships.
• B. The Galaxy object is required to contain existing roll-up summary fields.
• C. The Galaxy object has fewer than two existing master-detail relationships.
• D. The Star records are all required to have an existing value in their Galaxy field.

Correct answer: A, D

Explanation

Answer A is correct because a master-detail relationship can only exist if the detail (Star) has fewer than two existing master-detail relationships. Answer D is also correct since all Star records must be linked to a Galaxy for the relationship to function properly. Options B and C are incorrect as the Galaxy object does not need existing roll-up summary fields to convert the relationship, and its existing master-detail relationships are not relevant for this conversion.
