QUESTION 1

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets the stated goals.

You must create a project for shared code.

Solution: You implement the shared code in a Class Library (Universal Windows).

Does this meet the goal?

 

A. Yes
B. No

 

Correct Answer: A

Explanation:

The .NET Framework Portable Class Library project type in Visual Studio helps you build cross-platform apps and libraries for Microsoft platforms quickly and easily. Portable class libraries can help you reduce the time and costs of developing and testing code. Use this project type to write and build portable .NET Framework assemblies, and then reference those assemblies from apps that target multiple platforms such as Windows and Windows Phone.

Even after you create a Portable Class Library project in Visual Studio and start developing it, you can change the target platforms. Visual Studio will compile your library with the new assemblies, which helps you identify the changes you need to make in your code.

From scenario:

The app must be compatible with current and future XBOX apps that use C++.

QUESTION 10

You need to configure authentication for the app. Which two technologies should you use? Each correct answer presents part of the solution.

 

A. Windows Hello
B. Windows Kerberos
C. Azure Active Directory
D. Microsoft Passport

 

Correct Answer: AD

Explanation:

Microsoft Hello

Microsoft Hello provides simple multi-factor authentication using facial recognition (or iris, or fingerprints) that is used to access the Microsoft Passport private key stored in the secure TPM chip. For the first time, Microsoft has included the biometric software (middleware) in Windows 10 to support biometrics for authentication. In previous versions of Windows, the OEM (HP, Dell, Lenovo, etc) needed to add its own biometric middleware to support biometric authentication.

From scenario: The app must meet the following requirements related to security:

Note: Microsoft Passport

Microsoft has resurrected the Passport moniker for a new PKI credential system that requires multi-factor authentication. Most interesting about Microsoft Passport is that it fully supports the Fast IDentity Online (FIDO) Alliance standards which means it will work with many web/cloud services without modification. The plan is that users of cloud services supporting FIDO is that there will no longer be passwords associated with the user’s account.

Microsoft Passport involves a user logging onto the Windows 10 computer with multi-factor (PIN, face, iris, fingerprint, etc) and either creating a new account or associating an existing account with an IDentity Provider (IDP). Windows generates a public/private key pair with the private key stored securely outside of the Windows 10 OS. The public key is associated with the account so that a challenge can be sent that can only correctly respond to the IDP. Another key point to the Microsoft Passport credential system is that the user needs to enroll every device used to access the service (IDP).

QUESTION 3

You have two Universal Windows Platform (UWP) apps named Catalog and Research, respectively.

You need to create a service in the Catalog app that can be queried by the Research app.

Which three tasks should you perform? Each correct answer presents part of the solution.

 

A. Enter the package family name of the Catalog app in the Catalog app.
B. Add a Windows Runtime component to the Catalog app.
C. Enter the package family name of the Catalog app in the Research app.
D. Add an app service extension to package.appmanifest file in the Research app.
E. Add a Windows Runtime component to the Research app.
F. Add an app service extension to package.appmanifest file in the Catalog app.

 

Correct Answer: BCF

Explanation:

F: Example: Add an app service extension to package.appxmanifest In the AppServiceProvider project’s Package.appxmanifest file, add the following AppService extension to the <Application> element. This example advertises the com.Microsoft.Inventory service and is what identifies this app as an app service provider. The actual service will be implemented as a background task. The app service app exposes the service to other apps

B: Create the app service

An app service is implemented as a background task. This enables a foreground application to invoke an app service in another application to perform tasks behind the scenes. Add a new Windows Runtime Component project to the solution.

C: Deploy the service app and get the package family name The app service provider app must be deployed before you can call it from a client. You will also need the package family name of the app service app in order to call it.
