Network Topology Questions 1. What is the class of the given network address? Ans.: ...B........ PC2 PC4 2. What is the mask of the given address? Ans. ...255.255.0.0......... Fao Fao 3 How many subnetting bits are needed to achieve the 25 subnets? Ans.: ......... FO/2 R1 FO/2 S2 Cisco 2960 F0/1 Cisco 2960 S1 FO/1 4. What is the mask of each subnet? Ans.: ...255.255.248.0.. GO/1 G0/1 GO/O G0/1 Cisco 1941 5. How many host bits are left after subnetting i.e. host bits per subnet)? Ans.: ...11. Fao Fao 6. What is the number of total host addresses in each subnet? Ans.: ...2048. PC1 PC3 7. What is the subnetwork address of the second subnet? Ans.: ...180.100.8.0. 8. What is the broadcast address of the third subnet? Ans.: 9. What is the last host address of the fifth subnet? Ans. ............... Figure 1 Network of Part 4. Procedure 1. In packet tracer construct the network shown in Figure 1. Use straight-through UTP cables to connect the ports of the devices as shown in the figure. Use Cisco 1941 as the router and Cisco 2960 as the switches. The connected port names should be taken as shown in the figure. 2. Use the IP addresses of the first subnet of Table 2 for the LAN network connected to interface G0/0 of R1. Assign the first host address to the default gateway (i.e. to GO/O of R1), the second host address to VLAN 1 of S1, the third host address to PC1, and the last host address to PC2. 3. Use the IP addresses of the second subnet of Table 2 for the LAN network connected to interface G0/1 of R1. Assign the first host address to the default gateway (i.e. to G0/1 of R1), the second host address to VLAN 1 of S2, the third host address to PC3, and the last host address to PC4. 4. Based on the directions of steps 2 and 3 fill in the IP address information in Table 3. 10. What is the first host address of the fourth subnet? Ans.: 11. Expand the details of the first five subnets for the subnetting problem of this part in Table 2. Table 2 The first five subnets of the problem of Part 3.
