You have to subnet the network 192.168.160.0/21 into a number of equal size subnets based on the below logical topology. 1)Based on the topology, how many subnets are required? 4 3 2 1 2)How many bits must be borrowed to support the number of subnets in the above logical topology? 1 2 3 4 3)How many subnets does the borrowed bits create? 3 4 5 6 4)What subnet mask will be assigned to all devices? 255.255.255.0 255.255.252.0 255.255.254.0 255.255.255.128 5)How many usable host addresses does this subnetting create in each subnet? 512 510 520 508 6)What will be the first usable IP address and the broadcast IP address of the 1st subnet? First usable IP address: 192.168.160.0 Broadcast IP address: 192.168.160.255 First usable IP address: 192.168.160.255 Broadcast IP address: 192.168.161.255 First usable IP address: 192.168.161.1 Broadcast IP address: 192.168.162.255 First usable IP address: 192.168.160.1 Broadcast IP address: 192.168.161.255
