You have two computers that run Windows 7.

Both computers are connected to a network and have IP addresses within the 172.16.10.0/24 subnet.

You need to ensure that both computers can join a HomeGroup.

What should you do?

A.
Enable network discovery.

B.
Set the network location to Home network.

C.
Configure Windows Firewall to allow the Netlogon service.

D.
Change the IP addresses to be within the 192.168.1.0/24 subnet.

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.
