Q1. You develop a Universal Windows Platform (UWP) app that is available in the Microsoft Store.
Some users report that the app occasionally crashes.
You review the health reports from the Windows Dev Center dashboard and you discover that there are no Failure logs for the app. You need to ensure that the app failure information is available in the health reports from the Windows Dev Center dashboard. What should you do before you republish the app?
A. Create a custom logging event in the app.
B. Create a Windows Push Notification Services (WNS) service, and then add the cloud service URI to the client application.
C. Create a new app package that includes the .pdb symbol files.
D. Enable the code generation capability, and then create a new app package.
Correct
Answer: C
Explanation:
If you have included PDB symbol files, the Failure log chart will show details related to occurrences of specific symbols, including the total number of crashes and the average daily number of crashes per symbol.
Q2. You are developing a Universal Windows Platform (UWP) app.
In MainPage.xaml, you have the following markup.
You plan to implement localization for the following cultures:
de-DE
fr-CA
en-US
You create a folder within the project named Strings that contains a subfolder for each culture. Each subfolder contains a resource file named Greetings.resw. You need to ensure that TextBlock appears by using the appropriate localization.
Which two modifications should you make to MainPage.xaml? Each correct answer presents part of the solution.
A. Replace x:Name with x:Phase.
B. Change "Greeting" to "Resources/Greeting".
C. Change "Greeting" to "Greetings/Greeting".
D. Replace x:Name with x:FieldModifier.
E. Replace x:Name with x:Uid.
F. Change "Greeting" to "Greetings.resw/Greeting".
Correct
Answer: BE
Explanation:
E: The keys of the key-value pairs are x:Uid values that are placed by the developer in the original XAML. These x:Uid values enable the API to track and merge changes that happen between the developer and the localizer during localization.

Q3. HOTSPOT
You are designing a Universal Windows Platform (UWP) app that will access external data sources. The data sources have the following requirements:
The data must be stored in a relational database.
The data sources must be stored in a public cloud.
The app must not connect directly to the database.
The app must access the data sources by using HTTP verbs.
You need to identify the appropriate data storage type and the appropriate method to use to access the data sources. What should you identify? To answer, select the appropriate options in the answer area.
Hot Area:
Answer:

Microsoft Azure SQL database is a relationaldatabase-as-a-servicein the cloud.
Through the .NET Web API you can access relational database through HTTP verbs..Net’s Web API is an easy way to implement a RESTful web service using all of the goodness that the .net framework provides.REST stands for ‘Representational State Transfer’ and it is an architectural pattern for creating an API that uses HTTP as its underlying communication method.
Incorrect:
Not: Microsoft AzureDocumentDB
DocumentDB is a NoSQL(not relational)document database for big data solutions handling JSON data that require easy scaling and high availability.
Not: Microsoft Azure Table storage
Azure Table storage is a service that stores unstructured NoSQL(not relational)data in the cloud.

You are developing a Universal Windows Platform (UWP) app.
The app will display a text box named TextBox1 and a button named Button2.
If a user types in the text box, you need to ensure that the box is resized dynamically based on the size of the text. The buttons must always remain to the right of the text box and must always remain aligned.
How should you complete the code? To answer, drag the appropriate code elements to the correct targets. Each element may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
Select and Place:
Answer:
Explanation:
The new RelativePanel implements a style of layout that is defined by the relationships between its child elements. It's intended for use in creating app layouts that can adapt to changes in screen resolution.
Example:
<RelativePanel>
<TextBox x:Name="textBox1" Text="textbox" Margin="5"/>
<Button x:Name="blueButton" Margin="5" Background="LightBlue" Content="ButtonRight" RelativePanel.RightOf="textBox1"/>
<Button x:Name="orangeButton" Margin="5" Background="Orange" Content="ButtonBelow" RelativePanel.RightOf="textBox1" RelativePanel.Below="blueButton"/>
</RelativePanel>
