You are assigned a Class C Network Address. Which subnet masks will you use to create a Network with 8 Subnets, each with 30 Hosts?
- 255.255.128
- 255.255.240
- 255.255.224
- 255.255.192
255.255.255.224
Explanation:
You have to allocate 3 of the 8 bits in the last octet for Subnet identifiers to create a Network with 8 Subnets and 30 Hosts per Subnet. The result is a binary value of 1110000000 for the last octet in the Subnet Mask, which converts to a decimal value of 224.
