You are developing a Windows Store app by using JavaScript. The app will allow users to
customize various features. The customizations will be persisted by using the setAppSetting
function.
You need to persist the customizations.
Which code segment should you use?

You are developing two Windows Store style apps by using JavaScript. A Source app will
store sensitive customer information. A Target app will retrieve the stored information for
validation and further processing. The Source app must secure data by using a privatepublic key pair. Only the Target app must be able to consume data that has been secured by

the Source app. You need to ensure that the security of the data is not compromised. What
should you do?

You are developing a Windows Store app. You configure the app to allow a free trial period.
You need to prompt the user to purchase the full version of the app when the trial period
expires. What should you do?

DRAG DROP
You are developing a Windows Store app by using JavaScript. The app will use the
fileStream object to write text to a file. You need to write the text to the file and ensure that
the file is available to other apps. Which five 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.)

DRAG DROP
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, 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.)

HOTSPOT
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, select the correct action from each dropdown list in the answer area.)

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.)

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 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.)
