You need to prevent a custom application from connecting to the Internet.

What should you do?

A.
From Windows Firewall, add a program.

B.
From Windows Defender, modify the Allowed items list.

C.
From Windows Firewall with Advanced Security, create an inbound rule.

D.
From Windows Firewall with Advanced Security, create an outbound rule.

Explanation:
Outbound Rule
Outbound rules allow you to block and allow traffic that originates on the computer from traveling out to the network.

Creating WFAS Rules
The process for configuring inbound rules and outbound rules is essentially the same: In the WFAS console, select the node that represents the type of rule that you want to create and then click New Rule. This opens the New Inbound (or Outbound) Rule Wizard. The first page, allows you to specify the type of rule that you are going to create. You can select between a program, port, predefined, or custom rule. The program and predefined rules are similar to what you can create using Windows Firewall. A custom rule allows you to configure a rule based on criteria not covered by any of the other options. You would create a custom rule if you wanted a rule that applied to a particular service rather than a program or port. You can also use a custom rule if you want to create a rule that involves both a specific program and a set of ports. For example, if you wanted to allow communication to a specific program on a certain port but not other ports, you would create a custom rule.
