Your new Windows 8.1 computer is connected to your home wireless network.
You want to share music and photos on your new computer with other members of your family. You
want to avoid setting up separate user accounts for each member of your family. A single password
for all the shared files will suffice.
Which Windows 8.1 networking feature satisfies these requirements?

A.
Network Discovery

B.
HomeGroup

C.
Virtual Private Network

D.
Broadband (PPPoE)

Explanation:
A homegroup makes it easier to share files and printers on a home network. You can share pictures,
music, videos, documents, and printers with other people in your homegroup. Other people can’t
change the files that you share, unless you give them permission to do so.
