Salesforce Admin Certification Practice Test

What type of information can the roll-up summary fields display about related records?

1. Only the average value of a field.

2. Count total records but not their values.

3. Sum, min, max, or record count of a field.

4. Only boolean values about related records.

The correct answer is: Sum, min, max, or record count of a field.

Roll-up summary fields are specifically designed to aggregate information from related records in a master-detail relationship. They allow you to perform calculations across those related records, making them a powerful tool for summarizing data within Salesforce. The correct answer highlights that roll-up summary fields can display the sum, minimum, maximum values, or count of a specific field from the related records. For example, if you have a master record such as an Account and related detail records like Contacts, you could use a roll-up summary field to find the total number of Contacts associated with that Account (count), the total revenue generated (sum), the highest revenue from a single Contact (max), or the lowest revenue (min). This versatility is what makes roll-up summary fields essential for reporting and data analysis in Salesforce. Other options incorrectly limit the capabilities of roll-up summary fields, with some not encompassing all the aggregation functions available or implying that the fields can only deal with specific types of data. Hence, understanding the functions of roll-up summary fields is important for maximizing their use in Salesforce for effective data analysis and reporting.
