Salesforce Certified Platform App Builder — Question 295

Which of the following is true about Roll-up Summary Fields?

Answer options

• A. Roll-up Summary can be used to compute SUM, MIN, MAX, AVG over a set of records.
• B. Roll-up Summary Fields are readonly.
• C. Roll-up Summary can only be set on the parent of a Master-Detail or Lookup relationship.
• D. The results of the Roll-up Summary is displayed on the child in a master-detail relationship.

Correct answer: B

Explanation

The correct answer is B because Roll-up Summary Fields are indeed readonly by nature. Option A is incorrect as it describes the capabilities of Roll-up Summary but doesn't address their readonly status. Option C is misleading since Roll-up Summaries can only be created on Master-Detail relationships, not Lookup relationships. Option D is incorrect because the results of Roll-up Summaries are displayed on the parent record, not the child.
