When given a network topology, it is important to be able to determine the number of subnets required. In this lab, several scenario topologies will be provided, along with a base network address and mask. In Figure 1 represent network topology, you have been given the 192.7.7.128/25 network address to distributed subnet, with the following topology. (a) How many subnets are in Figure 1? (5 marks) (b) Determine the number of subnets in network topology? (5 marks) (c) Determine the first IP address and last IP address of host address range of each subnet? (10 marks) (d) Determine the number of the broadcasts address of each network
