You have a computer that runs Windows 7. You create a HomeGroup. You need to secure the HomeGroup to meet the following requirements:

* Allow access to the HomeGroup when you are connected to private networks.
* Block access to the HomeGroup when you are connected to public networks.

What should you do?

A.
From Network and Sharing Center, modify the advanced sharing settings.

B.
From the HomeGroup settings in Control Panel, modify the advanced sharing settings.

C.
Configure the HomeGroup exception in Windows Firewall to include Home or work (private) networks and block Public networks.

D.
Configure the File and Printer Sharing exception in Windows Firewall to include Home or work (private) networks and block Public networks.

Explanation:
Windows Firewall does not allow you to create firewall rules for specific network locations on the basis of port address. Windows Firewall does not allow you to create rules that differentiate between the home and work network locations. You can only create rules that differentiate on the basis of home and work or public network locations.

HomeGroup Connections
This option decides how authentication works for connections to HomeGroup resources. If all computers in the HomeGroup have the same user name and passwords configured, you can set this option to allow Windows to manage HomeGroup connections. If different user accounts and passwords are present, you should configure the option to use user accounts and passwords to connect to other computers. This option is available only in the Home/Work network profile.
