To calculate the number of hosts that will be supported on a network, we need to use the formula:
2^(32-subnet mask) - 2
In this case, the subnet mask is /22, which means that the first 22 bits are set to 1, and the remaining 10 bits are set to 0.
To calculate the number of hosts, we need to determine how many bits are available for host addresses. In this case, we have 10 bits available for hosts (since the subnet mask uses 22 bits), which gives us:
2^10 - 2 = 1022
The "-2" at the end of the formula is because the first and last addresses in a subnet are reserved for the network address and the broadcast address, respectively. Therefore, the number of hosts that will be supported on this network is 1022.
So the correct answer is C. 1022.
