PL-900 Demonstrate the capabilities of Power Apps Practice Question
You are building a canvas app for a field service team. The app must allow technicians to capture a customer signature on a touch screen and attach it to a work order record. Which Power Apps control should you add to the screen to meet this requirement?
⚠ Common exam trap
The trap here is assuming that any input control can capture a signature, when only the Pen input control provides a drawing surface.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Pen input control
The Pen input control is the only control in Power Apps canvas apps that provides a canvas for freehand drawing, making it ideal for capturing signatures. It can be bound to a data source so the signature image is saved with the work order. Other controls either display images, capture typed text, or use the camera, but none allow direct on-screen signing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Image control
Why it's wrong here
An Image control is used to display an image from a data source or a static file; it does not provide a drawing surface for user input. It cannot capture a signature. Therefore, it is not suitable for allowing technicians to sign on the screen. The Image control would only be useful after the signature image already exists.
- ✗
Text input control
Why it's wrong here
A Text input control allows users to type alphanumeric characters but does not capture handwritten signatures or drawings. While it could be used to type a customer's name, it cannot capture an actual signature image. This does not satisfy the requirement to capture a signature on a touch screen and attach it to a work order.
- ✓
Pen input control
Why this is correct
The Pen input control is designed specifically for capturing freehand drawing or signatures on touch-enabled devices. It stores the drawing as an image that can be saved to a data source, such as a work order record in Dataverse or SharePoint. This directly meets the requirement of capturing a customer signature and attaching it to a work order.
- ✗
Camera control
Why it's wrong here
The Camera control accesses the device camera to take photos or videos. While it could photograph a paper signature, it does not allow capturing a signature directly on the screen. The requirement specifies capturing a customer signature on a touch screen, which the Camera control cannot do. It is intended for image capture, not freehand drawing.
