You are developing a Windows Store app that allows users to compose musical beats and rhythms. The app must meet the following requirements: The app must save the work in progress in case the app suspends or terminates before users save their work. If the app closes before the work is complete, work in progress should be automatically reloaded so that users can continue seamlessly from where they left off.

You need to ensure that the app meets the requirements. How should the app save the work in progress?
A. by storing it in a memory-mapped file
B. by serializing it to a temporary app store
C. by serializing it to the roaming app store
D. by serializing it to the local app store

Drag and Drop Question
You are developing a Windows Store game that downloads virtual store information from two servers. Store information from Server1 is sent as a hex string. Store information from Server2 is sent as Base64 encoding. Data from Server1 is configuration data and must be captured before data from Server2 is captured. You need to compare the strings from each server to verify that the cryptographic buffers match. Which three 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 that displays and prints information. You have the following code.
You need to enable printing. How should you complete the initialization of the print functionality? (To answer, select the appropriate element from the drop-down list in the answer area.)
