Watchguard Network Security Practice Test

What static route must be added to the Firebox for clients on the trusted network to reach a server at 10.0.20.100?

1. Route to 10.0.20.0/24, Gateway 10.0.2.1

2. Route to 10.0.20.0/24, Gateway 10.0.2.254

3. Route to 10.0.20.0, Gateway 10.0.2.254

4. Route to 10.0.10.0/24, Gateway 10.0.10.1

The correct answer is: Route to 10.0.20.0/24, Gateway 10.0.2.1

To enable clients on the trusted network to reach a server at the IP address 10.0.20.100, the appropriate static route must direct traffic destined for the 10.0.20.0/24 subnet through the correct gateway. The correct choice includes defining a route to 10.0.20.0/24, which encompasses all IP addresses from 10.0.20.0 to 10.0.20.255, including the server at 10.0.20.100. The decision to use a specific gateway is also crucial, as it determines how the Firebox will forward the packets intended for that subnet. In this case, a gateway of 10.0.2.1 is specified, meaning that any packets directed to the specified subnet will be sent through that gateway for further delivery. In networking, every subnet needs a routing rule that specifies the correct gateway to ensure that traffic is appropriately directed. By correctly selecting the subnet and the gateway, clients on the trusted network gain access to the resources located within that subnet, enabling successful communication. It's also important to remember that misconfigurations or incorrect routes can lead to connectivity issues, underscoring the need for clarity in defining routes.
