Watchguard Network Security Practice Test

What subnet must your computer be on to use the Web Setup Wizard for your Firebox or XTM device?

1. 10.0.10.0/24

2. 10.0.1.0/24

3. 172.16.10.0/24

4. 192.168.1.0/24

The correct answer is: 10.0.10.0/24

To use the Web Setup Wizard for your Firebox or XTM device, your computer must be on the subnet 10.0.10.0/24. This specific subnet is designated for the initial setup and management of the device, ensuring that devices connected to this network can communicate effectively with the Firebox or XTM unit during the configuration process. Subnetting is critical in network management because it determines the range of IP addresses that devices on the network can use. The 10.0.10.0/24 subnet allows for a range of addresses from 10.0.10.1 to 10.0.10.254, making it suitable for private network environments where the firewall device is operating. By adhering to this specific subnet, users can guarantee that they are connecting to the device's management interface without networking conflicts or access issues. Choosing any of the other subnets would result in a failure to connect to the setup wizard, as those address ranges do not fall within the designated management subnet for the Firebox or XTM devices. The correct usage of subnetting ensures that the setup process is smooth and efficient, reflecting best practices in network security management.
