You are developing a Windows Store app that retrieves information from a social networking
application by using web services. The web services require authentication.
You need to recommend a solution to ensure that users are prompted for their credentials
only the first time they use the app, even if the users are using the app from another device.
What should you recommend?
A.
the Credential Manager
B.
roaming storage
C.
the Web Authentication Broker
D.
the Credential Locker
I believe this one is A

“If you haven’t yet heard about the Credential Locker that’s available for Windows Store apps, it’s time you did. Why? Because it not only simplifies the task of storing and retrieving user credentials, it stores them securely, and credentials roam with users “for free” along with their Microsoft account.”
I mean D
if the users are using the app from another device !
B
yes, from another device; the password vault roams with the user account.

I still think it’s D) credential locker
The first link speaks about option D and the second link speaks about option A.
The difference is that the second link is a official Microsoft web so…in the exam i would choose option A
