You are designing a Windows Phone 7 application that uses a Live Tile with background images. The Live Tile background will be updated with images that are stored on a remote server. Received push notifications will include information about the location of the remote image. You need to ensure that the application can use images from a remote server for the Live Tile background. You ensure that the HttpNotificationChannel is bound to the Live Tile. What should you do next? (Each correct answer presents part of the solution. Choose all that apply.)

You are designing a Windows Phone 7 application that requires push notifications. You need to ensure that the application is programmed to receive and handle raw notifications. What should you recommend?

You are designing a Windows Phone 7 application to work with large images that will be stored on a device. The application must be able to use the fastest method available to read and write large images. You need to recommend a data serialization method that ensures the fastest performance for reading and writing images. What should you recommend?

You are designing a Windows Phone 7 application that uses several pages for the entry of user data. A user can navigate freely among the pages in the application at any time. The user can also perform actions that use a PhotoChooserTask object to select images. You need to recommend a way for the selected images to persist when the user navigates through the application. What should you recommend?

You are designing a Windows Phone 7 application. A user receives a toast notification and responds while the application is running. The application loses some input when the user returns to the application after responding to the toast notification. You need to update the application so it restores user input when the application is resumed, but not when the application is restarted. Which option should you recommend for saving user input?

You are designing a Windows Phone 7 application that receives data from a Microsoft Windows Communication Foundation (WCF) service. A WCF service call fails when a user presses the Start button after the WCF service call begins but before it completes. You need to ensure that the WCF service call succeeds. What should you recommend?

You are designing a Windows Phone 7 application that has a Live Tile. You need to ensure that the Live Tile is updated every hour until the user unpins it. Which code segment should you recommend?

You are designing a Windows Phone 7 application that has a Live Tile. You need to ensure that the Live Tile is updated every hour until the user unpins it. Which code segment should you recommend?

You are designing a Windows Phone 7 application. Every three hours the application must change the application tile to show a picture depending on the current weather conditions. The application must perform this independently and without outside influence. You need to ensure that the application tile is updated every three hours. Which class should you recommend?

You are designing a Windows Phone 7 application that needs to send messages to update the application tile. The Push Notification Service will send more than a thousand messages a day. You need to design the Push Notification Service to deliver all messages. What should you recommend?
