  1. 1. You are creating a DHCP scope for your 192.168.1.32/28 subnet. The subnet consists of Windows 2000, Windows 98, and Windows 95 computers. You have two UNIX computers on this subnet that will be assigned the two highest available static IP addresses. The subnet's default gateway will be assigned the lowest available IP address on the subnet. Which scope should you create on your DHCP server? a. 192.168.1.34 - 192.168.1.46 b. 192.168.1.34 - 192.168.1.44 c. 192.168.1.33 - 192.168.1.45 d. 192.168.1.34 - 192.168.1.61 e. 192.168.1.33 - 192.168.1.60 2. Your network uses an address of 172.30.0.0/16. Your projected growth for the network indicates a need for at least 25 subnets with a minimum of 1,000 hosts per subnet.
