Question:
How many usable IP addresses are available on the 192.168.1.0/27 network?

• 256
• 254
• 62
• 30
• 16
• 32

Explanation: A /27 mask is the same as 255.255.255.224. This leaves 5 host bits. With 5 host bits, 32 IP addresses are possible, but one address represents the subnet number and one address represents the broadcast address. Thus, 30 addresses can then be used to assign to network devices.
