What type of Power Apps would you consider for the examiner`s mobile solution?

Answer options:

A.Model-driven app
B.Canvas app
C.Model-driven or canvas app
D.Portal app
E.Model-driven or canvas or portal app

Correct Answer: C 
As a Solution Architect, you need to know what Power Apps type best suits the customers’ requirements. 
There are three types of Power Apps applications: Model-driven — responsive Dataverse data-driven applications. This type is more data administration with a back-office and process focus.
Canvas — flexible phone or tablet applications that can use multiple data sources. The canvas app is focused on the end-user and helps to execute a particular task. It also provides device integration, like the use of the mobile camera.
Portal — external websites for interaction with Dataverse data. It has the end-user focus.
There are the following requirements for the examiner`s mobile solution: The app should work offline
The app should use Business process flows for the document’s checklists
The app should use a mobile camera to take pictures
The app should use AI Builder models for processing images of the plates
The app should integrate the Power Virtual Agents bot
Both model-driven and canvas apps can fit the above-defined profile. If you use a model-driven app as a basic app, you need to integrate a canvas app as a component. The canvas app will work with camera and AI Builder models. You use the Business process flow within the model-driven app and integrate the app with the Power Virtual Agents bot. 
You also can make the examiner`s mobile solution as a canvas app. You need to create a Business Process flow and then use Web API or make a custom connector for Business Process flow data presentation in the canvas app. You can integrate AI Builder models and Power Virtual Agents with the canvas app. 
Microsoft plans to merge both Power Apps types into the components that users can put on the Power Apps app`s screens. 
As a Solution Architect, you need to consider all the factors to make technical, cost, and business sound decisions for the customer`s benefit.
