You work as the enterprise administrator at ABC.com. ABC.com has a domain named ABC.com. The ABC.com network servers run Microsoft Windows Server 2008 and the client computers run Microsoft Windows Vista. ABC.com has a computer named ABC-SR02 used for FTP communications.

How would you configure the Windows Firewall to block communications taking place on port 25?

A.
By making use of X.25 protocols communicating on the ports.

B.
By creating an outbound rule using the Advanced Security snap-in of Windows Firewall.

C.
By adding an IPv4 address exception.

D.
By adding an IPv6 address exception.

E.
By creating an inbound rule using the Advanced Security snap-in of Windows Firewall.

Explanation:
To prevent ABC-SR02 from establishing communication sessions to other computers by using TCP port 25, you need to create an outbound rule from the Windows Firewall with Advanced Security snap-in.

By default, inbound network traffic to a computer that does not match a rule is blocked, but nothing prevents outbound traffic from leaving a computer. To block the network traffic for prohibited programs, you must create an outbound rule that blocks traffic with specific criteria from passing through Windows Firewall with Advanced Security
