161 Ralph has been instructed to use the network address 10.12.0.0/14 for the new network he is installing. What subnet mask value should he use when configuring his computers?255.248.0.0255.252.0.0255.254.0.0255.255.248.0255.255.252.0255.255.254.0

162 Ed has been hired to design a company's network. The company has an assigned Class C network address of 192.168.30.0. Ed's client wants the network to be configured with 10 subnets, each with 14 hosts. Is this configuration possible with the given address, and if so, how many subnets and hosts can Ed create on the network?Yes, this will work. By using 4 subnet bits, it is possible for Ed to create up to 16 subnets. He can then use the remaining 4 host bits to create 14 hosts on each subnet.No, this will not work. A Class C address cannot be subnetted to create 8 subnets.No, this will not work. Although there are sufficient bits available to create 10 subnets, there are not enough bits left over for Ed to create 14 hosts per subnet.Yes, this will work. Ed can create 10 subnets with 14 hosts per subnet. By using 3 subnet bits, he can create 10 subnets, which leaves 5 bits to create up to 30 hosts per subnet.
