QUESTION 6

You need to ensure that only the correct information is preserved when the user switches to another app.

Which actions should you perform? (Each correct answer presents part of the solution. Choose all that apply.

Case Study Title (Case Study):

Background

You are developing a Windows Store app by using C# and XAML. The app will allow users to share and rate photos. The app will also provide information to users about photo competitions.

Application Structure

The app stores data by using a class that is derived from the DataStoreBase class.

The app coordinates content between users by making calls to a centralized RESTful web service.

The app has a reminder system that displays toast notifications when a photo competition is almost over. The app gets the competition schedule data from the web service.

The app displays a list of images that are available for viewing in a data-bound list box. The image file list stores paths to the image files.

The app downloads new images from the web service on a regular basis.

Relevant portions of the app files are shown. (Line numbers are included for reference only and include a two-character prefix that denotes the specific file to which they belong.)

Business Requirements

The app must allow users to do the following:

– Run the app on a variety of devices, including devices that have limited bandwidth connections.

– Share and synchronize high resolution photographs that are greater than 1 MB in size.

– Rate each photo on a scale from 1 through 5.

Technical Requirements

The app must meet the following technical requirements:

– Retain state for each user and each device.

– Restore previously saved state each time the app is launched.

– Preserve user state and photo edits when switching between this app and other apps.

– When the app resumes after a period of suspension, refresh the user interface, tile images, and data with current information from the web service.

– Update the image list box as new images are added to the image file list.

– Convert the image paths into images when binding the image file list to the list box.

The app must store cached images on the device only, and must display images or notifications on the app tile to meet the following requirements:

– Regularly update the app tile with random images from the user’s collection displayed one at a time.

– When a photo is displayed on the tile, one of the following badges must be displayed:

– If the photo has a user rating, the tile must display the average user rating as a badge.

– If the photo does not have a rating, the tile must display the Unavailable glyph as a badge.

– Update the app tile in real time when the app receives a notification.

– Display only the most recent notification on the app tile.

The app must display toast notifications to signal the end of a photo competition. The toast notifications must meet the following requirements:

– Display toast notifications based on the schedule that is received from the web service.

– Display toast notifications for as long as possible.

– Display toast notifications regardless of whether the app is running.

– When a user clicks a toast notification that indicates the end of the photo competition, the app must display the details of the photo competition that triggered the toast notification.
