Variable Length Subnet Mask (VLSM) in IP Network Design

What is the main benefit of using Variable Length Subnet Mask (VLSM) in IP network design?

To allocate IP addresses more efficiently

What is the issue with traditional subnetting schemes?

They lead to wasted IP addresses

In a VLSM design, how are subnet masks assigned?

Using a smaller subnet mask for smaller subnets and a larger subnet mask for larger subnets
