What is the performance test result for each app?
HOTSPOT
You are preparing four Windows Store apps for deployment.
You test the apps by using the Windows App Certification Kit. The results are as shown in
the following table.
You need to identify which apps passed the performance test.
What is the performance test result for each app? (To answer, choose the correct test result
from each drop-down list in the answer area.)
You need to add a user to the UserTracker instance
You are developing an application that includes a class named UserTracker. The application
includes the following code segment. (Line numbers are included for reference only.)
You need to add a user to the UserTracker instance.
What should you do?
How should you complete the relevant code?
HOTSPOT
You are developing a Windows Store style app by using JavaScript. The app will send and
receive encoded information and will display the encoded information to the user in a
decrypted and recognizable state.
You need to appropriately decrypt the encoded information.
How should you complete the relevant code? (To answer, select the correct code segment
from each drop-down list in the answer area.)
How should you complete the relevant code?
HOTSPOT
You are developing a Windows Store app by using JavaScript. The app will call a WinMD
component to convert temperature.
The component exposes the following two members:
• A static variable named Fahrenheit
• A public method named GetInCelsius( ) that accepts an integer
You need to ensure that the app will display the temperature in Celsius and Fahrenheit.How
should you complete the relevant code? (To answer, select the correct code segment from
each drop-down list in the answer area.)
How should you complete the relevant code?
DRAG DROP
You are developing a Windows Store app for an airline. The app will provide current flight
status information.
The app will display the flight status on the lock screen if the user grants permission.
You have the following requirements:
• Display a dialog box that requests access to the lock screen.
• Display a message that indicates whether the user has granted access to the lock
screen.
You need to ensure that the requirements are met.
How should you complete the relevant code? (To answer, drag the appropriate code
segments to the correct locations in the answer area. Each code segment 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.)
Which testing strategies should you select?
DRAG DROP
You are designing a testing strategy for a Windows Store app by using HTML5, JavaScript,
and CSS3.
You need to use testing strategies that validate for the best performance.
Which testing strategies should you select? (To answer, drag the appropriate actions to the
correct locations in the answer are a.
Each action 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.)
Which four actions should you perform in sequence?
DRAG DROP
You are preparing a Windows Store app that will be distributed through the Windows Store.
You install the app on a test computer that runs Windows 8.
You must run functional test cases by using the Windows App Certification Kit.
You need to test the app before you deploy it to the Windows Store.
Which four actions should you perform in sequence? (To answer, move the appropriate
actions from the list of actions to the answer area and arrange them in the correct order.)
You need to implement the UpdateScore() method
You are adding a public method named UpdateScore to a public class named ScoreCard.
The code region that updates the score field must meet the following requirements:
It must be accessed by only one thread at a time.
It must not be vulnerable to a deadlock situation.
You need to implement the UpdateScore() method.
What should you do?
How should you complete the relevant code?
DRAG DROP
You are developing an application that will include a method named GetDat
a. The GetData() method will retrieve several lines of data from a web service by using a
System.IO.StreamReader object.
You have the following requirements:
The GetData() method must return a string value that contains the first line of the response
from the web service.
The application must remain responsive while the GetData() method runs.
You need to implement the GetData() method.
How should you complete the relevant code? (To answer, drag the appropriate objects to the
correct locations in the answer area. Each object 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.)
Which three code segments should you insert in sequence at line 09?
DRAG DROP
You are developing an application that includes a class named Kiosk. The Kiosk class
includes a static property named Catalog. The Kiosk class is defined by the following code
segment. (Line numbers are included for reference only.)
You have the following requirements:
Initialize the _catalog field to a Catalog instance.
Initialize the _catalog field only once.
Ensure that the application code acquires a lock only when the _catalog object must be
instantiated.
You need to meet the requirements.
Which three code segments should you insert in sequence at line 09? (To answer, move the
appropriate code segments from the list of code segments to the answer area and arrange
them in the correct order.)
