Explanation

A (not D): Scenario: Retrieve user data from the social network services by using the authentication credentials. C (not B): Scenario: When SSL is available, use SSL to retrieve data from social network Case Study 7 - Scenario 7 (Question 21 - Question 23) You are developing a Windows Store media sharing app for the sates and marketing team at Margie's Travel. The app will allow team members to download documents and media about current and proposed products and services from the company's cloud-based media manager service. Team members will be able to add new content to the cloud service and to print and Business Requirements - Team members must be able to download product information data sheets, marketing materials, and product demonstration video clips from the company's server. - Team members must be able to select and upload multiple files that contain new and modified content as a batch. - Team members must be able to stream video clips to other devices in the vicinity of the team member's device. The app will not support the streaming of photographs. - The app must allow team members to pause, restart, or cancel uploads and downloads of files. - The app must report both the progress and completion status of these operations. It must also return results about upload and download operations. - The app must include a photo viewer. When photos are added or deleted in the photo viewer window, they must animate in and out of the field of view. Remaining photos must move to fill the empty space created when photos are deleted. The photo viewer must support semantic zoom. - The app must display information on the lock screen of the device. The information must include text-based alerts and a value indicating the number of pending file downloads. Technical Requirements - The company has an existing component named VideoProcessor. This component compresses video clips and performs other processing before the video clips are uploaded to the media manager service. The component was written with managed code. The VideoProcessor component will also be used by Windows Store apps developed in HTML5 and JavaScript. The apps must be able to call the overload of the ProcessVideoO method that accepts a string and a Boolean value as parameters. - When a team member selects a video clip to download, the app must download the file as a background task. After a download has started, the app should maintain the network connection to the server even when the app is suspended. - The app must include a custom photo viewer control. The control will be updated frequently and may be deployed separately from the rest of the app. The photo viewer control must support templates and styles. - The app must use a Grid control as the root layout control. The photo viewer must be placed in the second row of the grid. - The appearance of the app must change when the app is not in full screen mode. The first row of the root layout grid must not change height-The second row must fill all available space. - Available video clips must be displayed in an extended ListView control class named DownloadedVideoList - The template for the DownloadedVideoList is already defined. - New video clips should be added to DownloadedVideoList when the DownloadVideo() method completes. - New video clip items in the DownloadedVideoList should color change periodically to alert the team member. Application Structure Relevant portions of the app files are as follows. (Line numbers in the code segments are included for reference only and include a two-character prefix that denotes the specific file to which they belong.) VideoProcessor.es MainPage.xaml.es
