3. You are a network administrator in your office. You have 255.255.255.224 subnet mask. What is the maximum
number of IP addresses that can be assigned to hosts on a local subnet that uses this subnet?
A. 15
B. 30
C. 16
D. 14
B. 30
To calculate the maximum number of IP addresses that can be assigned to hosts on a local subnet with a subnet mask of 255.255.255.224, you first need to determine the number of host bits in the subnet mask. In this case, the subnet mask 255.255.255.224 has 5 host bits.
To calculate the number of hosts, you use the formula 2^n - 2, where n is the number of host bits. In this case, it would be 2^5 - 2 = 30.
Therefore, the maximum number of IP addresses that can be assigned to hosts on this subnet is 30.
