問題文
A custom Lightning web component must display aggregated numbers computed across several objects using logic that no standard data service provides. What does the component need?
選択肢
- A Visualforce page embedded in the component, the only route to Apex.
- An Apex method exposed to the component so that the calculation runs on the server.
- A formula field on each of the objects involved plus a report placed next to the component, and Lightning web components cannot call server-side code and must read values that already exist on records.
- A record-triggered flow.
