Question

An Example of Adding a New VLSM Subnet

A. To add a new VLSM subnet, you must first determine the number of hosts needed on the new subnet.
B. Once you know the number of hosts needed, you can choose a subnet mask that will provide the desired number of hosts, while also ensuring that the new subnet does not overlap with any existing subnets.
C. To calculate the number of hosts on a subnet, you can use the following formula: 2^(32 - subnet mask) - 2
D. All of the above

Answer 1

The correct response is D. All of the above, which includes determining the number of hosts, selecting a non-overlapping subnet mask, and using the formula to calculate the number of hosts for adding a new VLSM subnet.

Step-by-step explanation:

The correct response to the student's question is D. All of the above. When adding a new Variable Length Subnet Mask (VLSM) subnet, it is essential to follow these steps:

1. Determine the number of hosts required for the new subnet.
2. Choose an appropriate subnet mask that accommodates the desired number of hosts and ensures there is no overlap with existing subnets.
3. Use the formula 2^(32 - subnet mask) - 2 to calculate the maximum number of hosts that can be allocated in the subnet.

It's critical to understand VLSM to efficiently utilize IP address space and organize networks in a scalable fashion.
