   A canvas app for customer service has a screen where agents select a customer and enter a note. When they click a button, the app must send the customer ID and note to a Power Automate flow that logs the interaction in a CRM system. The flow also needs to return a confirmation number. You need to implement this. What should you do?

   • AAdd two input parameters to the flow for customer ID and note, and add an output parameter for the confirmation number; use Run() in the app to pass data and capture the output.
   • BPass the customer ID and note as a single JSON string and have the flow parse it; return the confirmation number in the flow's response.
   • CStore the customer ID and note in a SharePoint list and have the flow read them from there; the flow writes the confirmation number back to the list.
   • DUse the Run() function but only pass the customer ID; have the flow look up the note from the app's data source.

   • BEncode all data into a single JSON string and pass it as one parameter.

   A canvas app for event registration has a form with multiple date fields. The app must validate that the end date is after the start date, and that the registration deadline is at least 7 days before the start date. If validation fails, the app must show a message and not trigger the registration flow. You need to implement this with Power Fx. Which approach should you use?

   • AUse the Validate() function on the form to check the date fields and then call the flow.
   • BUse the DateDiff() function in the Default property of the end date field to auto-correct the date.
   • CCall the flow first and let the flow validate the dates; the flow returns an error message if invalid.
   • DUse an If() formula in the button's OnSelect property that checks both conditions and only calls the flow if both are true; otherwise show a message.
