PL-900 Demonstrate the capabilities of Power Apps Practice Question
A company is building a Power Apps canvas app that will be used by field technicians on mobile devices. The app must allow technicians to capture photos and store them with related work order records in Microsoft Dataverse. The maker needs to add a control that lets users take a photo using the device camera. Which control should the maker add to the app?
⚠ Common exam trap
The trap here is thinking that the Camera control automatically saves photos to Dataverse; it only captures the image, and a separate action like Patch is required to store it.
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
✓
Add a Camera control, then use the Patch function to save the photo to the Dataverse table.
The Camera control is designed to capture photos using the device's camera. After a photo is taken, it is stored in the control's Photo property. To persist the photo with a work order record in Dataverse, the maker uses the Patch function to write the image to the appropriate record. This combination allows technicians to capture and save photos directly within the app.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add an Add Picture control and bind it to the work order record.
Why it's wrong here
The Add Picture control allows users to select an image file from their device, but it does not directly access the camera. For field technicians who need to take a new photo on the spot, this control is not suitable because it opens a file picker rather than the camera. It is better for uploading existing images.
- ✗
Add an Image control and set its Image property to the camera stream.
Why it's wrong here
The Image control is used to display an image, not to capture one. It cannot access the device camera directly. While you can display a photo taken by a Camera control in an Image control, the Image control itself does not provide camera functionality. The maker needs a Camera control to capture the photo.
- ✗
Add a Camera control and set its OnSelect property to save the photo to Dataverse.
Why it's wrong here
The Camera control is used to capture photos, but its OnSelect property is not where you save the photo. The Camera control has a Photo property that contains the image, and you typically use a button or the camera's OnSelect to trigger a save action. However, simply setting OnSelect to save does not automatically store the photo with the work order; you need to use a formula like Patch to create or update a record.
- ✓
Add a Camera control, then use the Patch function to save the photo to the Dataverse table.
Why this is correct
The Camera control provides a live preview and allows the user to capture a photo. The captured image is available in the control's Photo property. To save it to Dataverse, you use the Patch function to create or update a record, setting the image column to the Camera control's Photo. This is the standard pattern for capturing and storing photos in a canvas app.
