Which of the following would accommodate for at least 100 subnets with 450 hosts each?Question 4Select one:Class C network with a subnet mask 255.255.255.224Class B network with a subnet mask 255.255.254.0Class B network with a subnet mask 255.255.224.0Class C network with a subnet mask 255.255.255.128

The correct answer is "Class B network with a subnet mask 255.255.254.0".

Here's why:

1. Class C network with a subnet mask 255.255.255.224: This subnet mask allows for 8 subnets with 30 hosts each. This does not meet the requirement of 100 subnets and 450 hosts.

2. Class B network with a subnet mask 255.255.254.0: This subnet mask allows for 512 subnets with 510 hosts each. This meets the requirement of 100 subnets and 450 hosts.

3. Class B network with a subnet mask 255.255.224.0: This subnet mask allows for 32 subnets with 8190 hosts each. This exceeds the requirement for hosts but does not meet the requirement for subnets.

4. Class C network with a subnet mask 255.255.255.128: This subnet mask allows for 2 subnets with 126 hosts each. This does not meet the requirement of 100 subnets and 450 hosts.

Therefore, the only option that meets the requirement of at least 100 subnets with 450 hosts each is the Class B network with a subnet mask 255.255.254.0.
