Question
Network Topology A
You are given the 192.168.10.0/25 network address to subnet, with the following topology. Determine the number of networks needed and then design an appropriate addressing scheme.
Step 1: Determine the number of subnets in Network Topology A.
a. How many subnets are there? ___________
b. How many bits should you borrow to create the required number of subnets? _________
c. How many usable host addresses per subnet are in this addressing scheme? ___________
d. What is the new subnet mask in dotted decimal format? _________________________
e. How many subnets are available for future use? _______________
Step 2: Record the subnet information.
Fill in the following table with the subnet information

Network Topology B
The network topology from Part 1 has expanded to accommodate the addition of router R3 and its accompanying network, as illustrated in the following topology. Use the 192.168.10.0/25 network address to provide addresses to the network devices, and then design a new addressing scheme to support the additional network requirement.
Step 1: Determine the number of subnets in Network Topology B.
a. How many subnets are there? ___________
b. How many bits should you borrow to create the required number of subnets? ________
c. How many usable host addresses per subnet are in this addressing scheme? ___________
d. What is the new subnet mask in dotted decimal format? _________________________
e. How many subnets are available for future use? _______________
Step 2: Record the subnet information.
Fill in the following table with the subnet information:

Network Topology C
The topology has changed again with a new LAN added to R2 and a redundant link between R1 and R3. Use the 192.168.10.0/25 network address to provide addresses to the network devices. Also provide an IP address scheme that will accommodate these additional devices. For this topology, assign a subnet to each network.
Step 1: Determine the number of subnets in Network Topology C.
a. How many subnets are there? ___________
b. How many bits should you borrow to create the required number of subnets? _________
c. How many usable host addresses per subnet are in this addressing scheme? ___________
d. What is the new subnet mask in dotted decimal format _________________________
e. How many subnets are available for future use? _______________
Step 2: Record the subnet information.

G0/1 so/o/o S1 R1 R2 PC-A PC-BExplanation / Answer
As per Chegg policy, I am answering to only first 4 questions:
a.) Since router connects two different subnets. Therefore there are 2 subnets.
b.) In order to create 2 subnets, we require to borrow 1 bit.
c.) Since, network bits are 26. So host bits will be 32-26 = 6. Therefore, there are 26-2 = 62 usable hosts per network.
d.) new subnet mask: 255.255.255.192/26
Hope it helps, feels free to comment in case of any query.
