Exam AB-210 Topic 1 Question 28 Discussion

The correct answer is Goal metric . In Dynamics 365 Sales, the goal metric defines how goal performance is calculated. Microsoft explains that each goal uses a goal metric to determine how the goal is tracked, and goal metrics can track actual, in-progress, and custom values through rollup fields. For won opportunity revenue, the metric can use the Opportunity table as the source and roll up the actual value for opportunities that are closed as won.
The quarterly requirement is handled by the goal's time period. The goal metric specifies the calculation logic, including the source table, source attribute, date attribute, and source status such as Won. Microsoft's goal metric documentation states that the date attribute is validated against the goal time period, so records participate in the rollup only when their date falls between the goal start and end dates. A rollup query is not the best answer because it only applies additional filtering criteria to an existing goal metric; it does not create the core calculation.
