You have a computer named Computer1 that runs Windows 7.

Computer1 is a member of an Active Directory domain. Remote Desktop is enabled on the computer.

You share a folder on Computer1.

You need to configure Computer1 to meet the following requirements:

* Allow computers in the local subnet to access the shared folder.
* Prevent computers in remote subnets from accessing the shared folder.
* Allow all computers to connect to Computer1 by using Remote Desktop.

What should you do?

A.
Modify the subnet mask.

B.
Modify the Public folder sharing settings.

C.
Disable network discovery on all computers located in remote subnets.

D.
Modify the properties of the File and Printer Sharing firewall exceptions.

Explanation:
Network Profiles
Network profiles are important because you can use them to apply different collections of firewall rules based on which network profile is active. A significant difference between Windows Vista and Windows 7 is that in Windows 7, profiles apply on a per-network interface basis. This means that if you have one network adapter connected to the Internet and another connected to your office LAN, different sets of rules apply for each connection. The firewall in Windows Vista chooses the most restrictive network profile when a computer has connections to different network types and applies the
most restrictive set of rules to all interfaces.

Allowing Programs Through Windows Firewall
Windows Firewall allows you to configure exceptions based on programs. This differs from Windows Vista where Windows Firewall would allow you to configure exceptions based on port address. You can still create rules based on port address; you just have to do it using WFAS, covered later in this lesson. You can also allow specific Windows 7 features, such as Windows Virtual PC, through Windows Firewall. Feature rules become available when you enable the feature using the Programs And Features item in Control Panel. To add a rule for a feature or program, click Allow A Program Or Feature Through Windows Firewall item in the Windows Firewall section of Control Panel. The figure shows a list of currently installed features and any programs for which rules have been created as well as the profiles for which rules concerning those programs and features are enabled.

File and Printer Sharing
This feature is used for sharing local files and printers with other users on the network. (Uses NetBIOS, LLMNR, SMB and RPC)
