A canvas app can connect to more than 200 data sources and can be built to run as a web, mobile or tablet application. Is this statement correct?

AYes Correct
BNo

Canvas apps reach more than 200 data sources and target web, mobile and tablet form factors. The app-types grounding says canvas apps connect to more than 200 data sources and that you can build them for web, mobile and tablet applications, so the statement holds on both counts.

Why A is correct: Correct. The app-types grounding says canvas apps connect to more than 200 data sources and that you can build them for web, mobile and tablet applications, so the statement holds on both counts.

Why B is wrong: Answering No is wrong because the grounding states a canvas app connects to your choice of more than 200 data sources and that you can build canvas apps for web, mobile and tablet applications.

Exam traps in Describe Microsoft Power Apps

Answers that look right on this material and are not. Each one is a distractor from a different question in the PL-900 bank for this domain.

A canvas app, which is responsive across all devices the moment it is published
Why it is wrong: Canvas apps are only responsive if the maker designs them that way, so responsiveness is not automatic and would require extra layout work.
A model-driven app, because its layout is generated from the tables and views that you add
Why it is wrong: Model-driven apps are a real same-category Power Apps app type, so they tempt. They are wrong here because much of the layout is determined for you by the components added, not arranged pixel by pixel.
A model-driven app, which reads its records from Dataverse tables only
Why it is wrong: Model-driven apps are a real app type, but their data platform is Dataverse only, so they cannot bind directly to SharePoint, Excel, and Salesforce as the scenario requires.
