A company uses voice agents to capture customer responses, and the system must store user...

Copilot Studio Question nodes are designed to collect information from users and automatically store the resulting value in a variable. Microsoft explicitly states that the response captured by a Question node can be reused later in the same conversation. The variable can represent structured entity data, multiple-choice input, free-form responses, or values obtained through voice and supported DTMF interaction.

Topic variables are scoped to the topic in which they are created but can also be passed between topics when the interaction design requires reuse across a broader conversation path. For values that must be available throughout the complete session, the variable can additionally be promoted to global scope. Microsoft documents that global variables remain available across topics during the same user session.

A greeting message only outputs information and does not capture a reusable value. A scheduled report operates after the interaction and therefore cannot drive real-time conversational logic. A knowledge article is a static knowledge resource and cannot represent an individual caller's dynamically supplied value.
