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. 255.255.128 255. 255.255.240 255. 255.255.224 255. 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.
