Problem 40 (3 points): a). Subnet Number Subnet Mask 200.1.1.128 255.255.255. 200.1.1.64 255.255.255. 200.1.1.32 255.255.255. 200.1.1.0 255.255.255. Note: this is only one possible arrangement. b). If D grows to 34 hosts, D will need 6 bits host field. There are many possible solutions! For example, the organization can subdivide department A into two subnets. Give D 6 bits for host field.
