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? 2)How many bits must be borrowed to support the number of subnets in the above logical topology? 3)How many subnets does the borrowed bits create? 4)What subnet mask will be assigned to all devices? 5)How many usable host addresses does this subnetting create in each subnet? 7)What will be the first usable IP address and the broadcast IP address of the 1st subnet?
