AI-103 Certification Practice Question #7

Question

You have a Microsoft Foundry project that contains a workflow for a customer support triage process.
You have an Ask a question node that stores user responses in a local variable named Var01.
You need to create the following Power Fx expressions:
An if/else condition expression that ensures that Var01 contains a value
A Send message expression that returns the stored user response in uppercase
How should you configure the expressions? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Accepted Answer

The condition must be true only when Var01 *contains a value*. `IsBlank(Local.Var01)` is true when the variable is empty, so the "has a value" test is its negation, `Not(IsBlank(Local.Var01))`. `IsEmpty` is for testing whether a table has records, which does not apply to a single stored user response. For the Send message, the response must be returned in uppercase, which is the `Upper()` function; the variable is a local (topic-scoped) variable, so it is referenced as `Local.Var01`, not bare `Var01`. Embedding the formula in a Send message uses the `{ ... }` syntax, giving `{Upper(Local.Var01)}`. The plain `{Local.Var01}` returns the value unchanged (no uppercasing) and `{Upper(Var01)}` uses an unqualified variable name that isn't the correct local-scope reference. No Suggested Answer or community votes exist; the function semantics are firmly grounded in MS Learn, but the exact local-variable reference syntax carries minor uncertainty, so confidence is 82%.
