Answer: Topic 3, Scenario 3
Background
A. Datum Corporation manufactures electronic measuring equipment that is sold worldwide. The equipment requires periodic inspection and calibration by a team of inspectors. The equipment supports near field communication (NFC).
Inspectors currently receive daily email messages that list the locations they must visit that day and the equipment they must inspect calibrate, or update. To request schedule changes, inspectors must call, fax, or email a support center.
A. Datum plans to develop a Windows Store app that connects to a scheduling application hosted in Microsoft Azure. The app will allow inspectors to view client information, equipment information, and other documentation. Inspectors will use the app to report inspection results back to the company's Microsoft Azure application.
Business Requirements
Inspectors must be able to use the app to perform the following equipment-related tasks:
....
Gather information about each piece of equipment during inspections.
Update equipment software and firmware during inspections,
Identify missing and outdated equipment.
Submit orders for replacement equipment to the customer support team.
The app must support the following scheduling requirements:
.
When an inspector signs in to the app, daily schedule and task information must
automatically download to the inspector's Windows device. The information must include client locations, equipment inventory at each location, and equipment settings. The files contain sensitive and proprietary information.
. Inspectors must be able to request a list of other clients within a Specified search distance who might requirelocation, and equipment settings. The files contain sensitive and proprietary information.
. Inspectors must be able to request a list of other clients within a specified search distance who might require equipment inspection. . Inspectors must be able to refuse a task and remove it from their schedule.
Technical Requirements
File Download, Storage, and Security . When an inspector connects the app to a piece of equipment, the current equipment software, firmware, drivers, and updates must be copied to the inspector's Microsoft OneDrive folder. . Inspectors must be able to search for equipment software and firmware updates stored in their OneDrive folders. . Downloaded files must be enrolled in selective wipe and made unavailable eight hours after download. . The app must use background tasks to download files to the users' devices. . All content files downloaded for the inspectors use must be available for searching in the app. . All data transferred by the app between the Windows devices and the Microsoft Azure application must be secured and encrypted.
Equipment Interface and Connections . While the app is connected to a piece of equipment, inspectors must be able to simultaneously display the app and the content of their OneDrive folders. . The user interface must include a slide control that allows the inspector to specify a search range for nearby clients. . Inspectors must connect the app to any piece of equipment by using a tap connection.

Topic 6, Scenario 6
Application Information
You are developing a Windows Store app by using JavaScript. The app is named Print
Near Me. The app will allow mobile users to find printers in their local area that subscribe to the Print Near Me network.
The Print Near Me app collects status data from subscribed networks, coordinates this data with the status of printers that are listed in the central Print Near Me service, and displays the closest locations that meet a user's printing requirements. The locations are identified by pinpoints on a map. The app uses a Printer Survey background task to populate the map.
The Print Here feature communicates with the central Print Near Me web server and nearby printers, and generates custom printer interfaces based on the available printers. The printer interfaces require complex calculations that involve repeated communications between the app and the central web server, and may result in high memory usage.
Printer providers may indicate whether a subscribed printer is available to the network or unavailable at any time.
Business Requirements
You have the following business requirements:
. . .. ...
Printer providers must have the option to approve users for each printer through
instant messaging or email.
When a user launches the Print Near Me app, the Printer Survey task must initiate
communication between the app and the central web server to populate the map.
Map pinpoints must be displayed as follows:
If the printer is available and does not require permission to print, display a green
pinpoint.
If the printer is available and requires permission to print, display a yellow pinpoint.
If there is a printer or network status error, display a red pinpoint.
Users must be able to initiate printing to a nearby printer by clicking or tapping the
printer's pinpoint and then clicking Print Here.
Technical Requirements
You have the following technical requirements:
.... .. .
The Print Here feature must run in a background process.
The Printer Support feature must log and dispatch error messages.
Log error messages locally.
When the network is available, synchronize data with the central Print Near Me
web server.
Background task events must be logged locally.
The printer interface calculations must use the Printer Survey task for
communication to all sources.
The Printer Survey task must push data to the app when the app is available.
Testing Requirements
You have the following testing requirements: . Simulate user interactions in the app as part of the tests. . Test the app performance on a variety of devices that have different capabilities, such as processing speed and screen resolution. . Generate a file on each device for analysis in Microsoft Visual Studio. (Devices will not have Visual Studio installed.) . Generate a file on each device for analysis in Microsoft Visual Studio. {Devices will not have Visual Studio installed.) . Identify the app components that are called most frequently and that use the most CPU resources. . Ensure that the app detects the location of all printers and consistently reports loss of connection.
