a) Circle all sub-networks in the network shown in Figure 2. In the same figure, assign IP addresses given the following subnet numbers: Router 1 Switch Router 2 199 1 server Router 3 20 workstations Figure 2 - Network to be assigned IP addresses 10.10.10.0/24 10.10.20.0/24 10.10.30.0/24 Switch b) How many nodes are there in Figure 2? Workstation 1 Workstation 2 Printer Server1 10.10.40.0/24 10.10.50.0/24 10.10.60.0/24 (Hint: You may not need all these subnets. Use only the ones you need for the network in Fig. 2) c) How many point-to-point links are there in Figure 2. Highlight the point-to-point link(s) and write PPP on each one.
