With VLSM, what prefix should be used on a network that has a planned maximum of 25 devices?

• /29
• /26
• /28
• /27
• /25

Explanation: 5 bits must be left to accommodate 25 network devices. With 5 host bits, up to 30 network devices can be placed on a network with a /27 prefix. 5 bits for hosts will yield 25=32 host addresses, but only 30 addresses are valid to be assigned to devices.
