Salesforce Certified Advanced Administrator — Question 31

Universal Containers wants to create a Job Application custom object related to a Job Posting custom object. They would also like a no-code solution to calculate the number of Job Applications for each Job Posting.
What type of field should an administrator create on the Job Application to enable this functionality?

Answer options

Correct answer: A

Explanation

The correct answer is A, Roll-up Summary, because it allows the calculation of aggregate values from related records in a master-detail relationship. Options B (Lookup) and C (Master-Detail) do not inherently provide a method for aggregation, while D (Formula) is used for calculations but cannot summarize records.
