Exam PL-100 topic 1 question 31 discussion

I think this answer is correct simply because, if you read the question carefully, it says, "You want to make sure that the app shows the user's photo upon scanning their ID cards.", to be more specific," app shows the user's photo upon scanning". To do this, you will need to scan the card yes, but to display the employee photo, you will need an image control.

Yes, it does. You can use the Image control in Power Apps to show individual images that aren’t part of a data set or incorporate images from records in data sources. You can also show the full name, email address, and picture that’s associated with the user who’s signed in to a canvas app. This feature can be used to automatically fill in a form or show information about a user in a canvas app. https://learn.microsoft.com/en-us/power-apps/maker/canvas-apps/controls/control-image https://learn.microsoft.com/en-us/power-apps/maker/canvas-apps/show-current-user https://learn.microsoft.com/en-us/power-apps/maker/canvas-apps/reference-properties

Answer is A

Image control is correct. Picture control would be needed, if you need to add a picture manually. To display a picture stored in a variable, the image control is needed

answer will be B, picture control to be more specific. This control is a grouped control containing two controls: an Image and an Add picture button. The Image control shows the uploaded image or a placeholder if no image has been uploaded. The Add picture button prompts for an image to be uploaded. https://docs.microsoft.com/en-us/power-apps/maker/canvas-apps/controls/control-add-picture

I think it is more likely to i) Scan the QR code (instead of scan the full ID card wont make sense) ii) Retrive the photo from records iii) verify the photo manually So the make sure the app shows the photo is related to image control eventhough you use barcode control to scan the QR code

I would say yes this is correct. Could this not be achieved using the visible function and creating a formula that sets visible to true when certain conditions are met, in this case when the ID has been scanned and the image has been retrieved from the user profile, or something like that.

Image control just displays an image, it's a no from me

Control required here is Barcode Scanner not image control

Correct!
