Salesforce Certified Platform App Builder — Question 187

Universal Containers has created the custom objects Candidate and Interview in Salesforce to track candidates and interviews respectively. The company wants to track the total number of interviews a candidate has gone through on the candidate record without writing any code.
Which two actions should an app builder take to accomplish this requirement? (Choose two.)

Answer options

• A. Use a formula field on the Candidate record to show the total number of interviews.
• B. Use a roll-up summary field on the Candidate record to show the total number of interviews.
• C. Use a master-detail relationship between the Candidate and Interview objects.
• D. Use a lookup relationship between the Candidate and Interview objects.

Correct answer: B, C

Explanation

The correct answer is B and C because a roll-up summary field can aggregate the total number of related Interview records on the Candidate record, and a master-detail relationship allows this type of summary. Options A and D are incorrect because a formula field cannot count related records, and a lookup relationship does not support roll-up summary fields.
