Lab 1: VLSM Network Topology 20 Hosts Given IP Address 172.16.0.0/21 Fa0/O SO/O DCE 1 Switch Server 4 Switches S0/O 20 Switches FaTR a1/0 64 Hosts 460 Hosts Scenario In this activity, you have been given the network address 172.16.0.0/21 to subnet and provide the IPaddressing for the network shown in the Topology Diagram. VLSM will be used so that the addressing requirements can be met using the 172.16.0.0/21 network. Task 1: Examine the Network Requirements. Based on the topology diagram, examine the network requirements and answer the questions below. Keep in mind that IP addresses will be needed for each of the LAN interfaces. 1. How many subnets are needed? 2. What is the maximum number of IP addresses that are needed for a single subnet? 3. How many IP addresses are needed for Student LAN? 4. How many IP addresses are needed for Instructor LAN? 5. How many IP addresses are needed for Administration LAN? 6. How many IP addresses are needed for each of the WAN links between routers? 7. What is the total number of IP addresses that are needed
