What does the ability to specify a different subnet mask for the same network range across various subnets allow a network engineer to do?
Assign one single subnet mask to all subnets within the network to simplify the routing process.
Allocate IP addresses more efficiently by creating subnets of varying sizes within a larger network.
Create multiple subnets with the same number of hosts to ensure uniformity across a network.
Increase the number of available IP addresses within a network by extending the range of the subnet mask.
