VLSM: Efficient IP Address Allocation

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

To reduce the number of subnets in a network
To simplify the network configuration
To increase the number of available IP addresses
To allocate IP addresses more efficiently and effectively (correct)

What is the result of using a traditional subnet mask in a network with subnets of different sizes?

Optimal use of IP addresses
Increased network security
No impact on IP address usage
Inefficient use of IP addresses (correct)

What is the purpose of using different subnet masks in VLSM?

To create a hierarchical network structure
To increase the number of available subnets
To simplify the network configuration
To allocate IP addresses based on the number of hosts in each subnet (correct)
