Final answer:
To add a new VLSM subnet, carefully plan your IP address allocation and choose a smaller subnet mask. In this case, it would be 192.168.0.128/25. By doing this, you have successfully added a new VLSM subnet.
Step-by-step explanation:
To add a new VLSM subnet, you need to carefully plan your IP address allocation. Let's say you have an existing subnet with a network address of 192.168.0.0/24. Now, you want to add a new subnet with a larger number of hosts. You can choose a smaller subnet mask, such as /25, which will give you 128 hosts. To calculate the new network address, you need to find the first available subnet in the range. In this case, it would be 192.168.0.128/25. By doing this, you have successfully added a new VLSM subnet.
