Background

Current environment

Sales representatives submit weekly status reports to regional managers. There is no standardized format for these status reports. The process for managing status reports is challenging.

Wide World Importers has decided to use Microsoft 365, Microsoft Azure, and Power Platform for future app development. Both Wide World Importers and Tailwind Traders have identical Microsoft SharePoint and Azure configurations. Both companies use separate tenants.

Requirements

Application

You must create a mobile app to streamline the creation of status reports by sales representatives. You must make the same app available to Tailwind Traders.

The mobile app must meet the following requirements:

– Minimize the use of code.

– Use formulas and expressions when necessary.

– Support a variety of visual layouts.

– Use a SharePoint list to store information about regional managers and sales representatives.

– Use Azure SQL Database to store other data.

Status reports

– Sales representatives must provide a weekly status report for all work processes each Monday.

– Representatives must enter the following information for each process:

– If a sales representative submits a status report and assigns the At Risk status to a process, the app must prompt the sales representative to enter a detailed description for the risk. This information must be emailed to the regional manager. If the category is Work/life balance, the information must be carbon copied to the human resources department.

– If a sales representative does not submit a weekly status report by an agreed upon deadline, the system must send an email to remind the sales representative.

– The app must be able to run both online and offline. If the mobile device on which the app runs is connected to the internet, the app must immediately submit the status report.

– You must display a visual indicator in the app so that sales representatives know whether the app is offline before submitting reports.

– When data is submitted offline, the data must be stored in the app until the app is back online.

Technical

Regardless of the UI layouts, the data recorded must be standardized in the Azure DB tables. You must use global variables in the app.

Deployment

– Before deploying the app to production, you must ensure that the app conforms to Microsoft accessibility and performance guidelines.

– The completed app and all supporting components must be provided to Tailwind Traders.

– Tailwind Traders must not be able to make changes to any of the components.

– You must use the following version control numbering scheme:

Major: The last two digits of the year the app is packaged

Minor: Two digits that represent the month when the app is packaged

Build: A number that is incremented to represent significant changes to the app

Revision: The incremented revision for a package

– New versions of the application must completely replace previous versions of the app.

– When identifying versions of the app solution, all dependencies, entities, and user interfaces components must be identified to avoid any unintentional issues caused by reverting individual components to a previous version.

– Previous versions of the mobile app must be available for roll back purposes.

– All versions of software that have been used in production must be retained for five years.

Issues

The mobile app has been live for several months. Eight versions of the app have been released since the initial version of the app was deployed to sales representatives. You must revert the app to an earlier version and redesign some features.

User1 often works in a warehouse that does not have internet connectivity. User1 needs to edit an existing status report and submit a new status report.

Several sales representatives have accessibility restrictions. User2 is visually impaired and cannot see images. User3 is unable to use a mouse.

You need to provide the app to Tailwind Traders.

Explanation:

Box 1: App Checker

Scenario: Several sales representatives have accessibility restrictions. User2 is visually impaired and cannot see images. User3 is unable to use a mouse.

Users who have vision, hearing, or other impairments can use your canvas app more easily and successfully if you consider accessibility as you design how the app looks and behaves. If you’re not sure how to make your app more accessible, you can run the AppChecker Accessibility checker in Power Apps Studio.

Box 2: Solution Checker

Scenario: Before deploying the app to production, you must ensure that the app conforms to Microsoft accessibility and performance guidelines.

Use solution checker to validate your model-driven apps in Power Apps.

Correct Answer:

Explanation:

Box 1: 1.0.0.0

When identifying versions of the app solution, all dependencies, entities, and user interfaces components must be identified to avoid any unintentional issues caused by reverting individual components to a previous version.

A solution’s version has the following format: major.minor.build.revision. An update must have a higher major, minor, build or revision number than the parent solution. For example, for a base solution version 3.1.5.7, a small update could be a version 3.1.5.8 or a slightly more signficant update could have version 3.1.7.0. A substantially more significant update could be version 3.2.0.0.

Box 2: 20.11.1.1

Scenario:

You must use the following version control numbering scheme:

– Major: The last two digits of the year the app is packaged

– Minor: Two digits that represent the month when the app is packaged

– Build: A number that is incremented to represent significant changes to the app

– Revision: The incremented revision for a package

New versions of the application must completely replace previous versions of the app.

Correct Answer:

Explanation:

Box 1: Power Apps mobile app

Scenario:

User1 often works in a warehouse that does not have internet connectivity.

User1 needs to edit an existing status report and submit a new status report.

The app must be able to run both online and offline. If the mobile device on which the app runs is connected to the internet, the app must immediately submit the status report.

You can build offline capabilities in your PowerApps app so your app users can access some data or save some data even when they don’t have an internet connection.

Box 2: Connector

Scenario: Azure SQL Database is used to store other data

Use the SQL Server connector to connect to SQL Server, in either Azure or an on-premises database, so that you can manage your data with create, read, update, and delete operations.

You need to modify the app design to meet the accessibility needs of the sales associates.

Which properties should you configure? To answer, drag the appropriate properties to the correct restrictions. Each property may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point.

Correct Answer:

Explanation:

Box 1: AccessibleLabel

Scenario: Before deploying the app to production, you must ensure that the app conforms to Microsoft accessibility and performance guidelines.

User2 is visually impaired and cannot see images.

AccessibleLabel is a label for screen readers.

An empty value for Image, Icon, and Shape controls will hide the controls from screen reader users.

Box 2: TabIndex

User3 is unable to use a mouse.

TabIndex determines if the control participates in keyboard navigation.

Keyboard navigation is an important aspect of any app. For many, the keyboard is more efficient than using touch or a mouse. The navigation order should:

Mirror what is seen visually.

Only have a tab stop at controls that are interactive.

Follow either an intuitive across and then down "Z" order or a down and then across "reverse-N" order.
