Salesforce Certified Platform App Builder — Question 62

Which three statements are true about Master-Detail relationships? (Choose three.)

Answer options

• A. You can't convert it if there is a roll-up summary field.
• B. Converting a look-up to master detail changes the OWD to Controlled by Parent.
• C. A look-up can be converted to a master detail if there are existing records with null values.
• D. SF displays a waiting page after you request to change a master detail to a look-up or vice versa.

Correct answer: A, B, D

Explanation

Option A is correct because the presence of a roll-up summary field prevents conversion. Option B is also correct as changing a look-up to master detail does indeed modify the OWD to Controlled by Parent. Option D is true since Salesforce does display a waiting page during the conversion process. However, option C is incorrect because you cannot convert a look-up to a master detail if there are existing records with null values.
