PDI Question #83: Real Exam Question with Answer & Explanation

Question

A developer created these three Rollup Summary fields in the custom object, Project__c: The developer is asked to create a new field that shows the ratio between rejected and approved timesheets for a given project. Which should the developer use to implement the business requirement in order to minimize maintenance overhead?

Options

• ARecord-triggered flow
• BFormula field
• CApex trigger
• DField Update actions

Explanation

To calculate a ratio between rejected and approved timesheets using existing rollup summary fields on Project__c, a formula field is the most efficient choice to minimize maintenance overhead.

Common mistakes.

• A. A record-triggered flow could perform this calculation and update a field, but it requires more configuration and introduces an automation layer that is unnecessary when a simple declarative formula can achieve the same result.
• C. An Apex trigger would involve writing, testing, and maintaining code, which is a higher maintenance overhead than a declarative formula field for a straightforward calculation based on existing fields.
• D. Field Update actions are typically used within workflow rules or flows to update fields based on specific criteria, and are not a standalone mechanism for calculating a ratio based on other fields.
