Part 1
Student1
How many bits do you borrow? Justify your answer.

The director wants 64 departments so 64 subnets. 2n-2>=64. Hence, the minimum number of bits to borrow is N = 7, where 27-2>=126 fulfill the 64 subnets.




What is the new subnet mask? Show working clearly.

The company is given a network address of 128. 1. 0. 0 so it is a class B network and its default subnet mask is 255.255.0.0.
The new subnet mask is 255.255.254(11111110).0


At this point – comments given by the other members.

Summary:

1. Which part needs to be corrected, part 1, 2, 3, 4 or 5? Explain why and show the correct and final answer for that particular part here (correction in BLUE). [student 6, if not 1]


Correct No Correction Needed


2. What do you suggest to change for efficiency or better performance from part 1 to 5? Elaborate your view in support of your stand (change or no change needed). [student 6, if not 2]

More Subnets and Little Users


3. What type of Unshielded Twisted Pair (UTP) cable do you use to connect from one PC to the router console port for router configuration? [student 3]

Rollover Cable


4. Since there are so many users in each department, name one network device that you can use to connect users that are in the same subnet together. [student 4]

Switch

5. For the size of this company, do you propose dynamic or static addressing? Explain your rationale. [Student 5]


Dynamic Host Configuration Protocol this is to automatically assign users with their own unique Ip addressing
