1. Design an Ethernet network to connect a single client PC to a single server. Both the client and the server will connect to their respective workgroup switches via UTP. Their workgroup switches are connected directly by a trunk link. The two switches are 1,700 meters apart. They need to communicate at 500 Mbps. Your design should specify the transmission link between the switches. 2. Add to your design in the previous question. Add another client next to the first client. This client will also communicate with the server and need only 100 Mbps in transmission speed. Again, your design should specify the locations of switches and the transmission link between the switches.
3. What are the advantages for using power over Ethernet (POE)?
4. What are the potential risks to users with using powered switch ports?
5. How do you think the above risks can be avoided in the POE Plus standard?
6. What primary differences are there between managed and unmanaged switches?
7. In what instances would it make sense to use an unmanaged switch?
8. What is the best means for mitigating the single points for failure on an Ethernet network?
9. Give two business-use examples for each fiber types.
10. When implementing SNMP for managed switches, what security planning principle must be considered?

Write a program to analyze student’s scores. each student’s id and 4 original test scores are saved in the attached file “student_id_scores.txt”. assume there are exactly 15 students in the class.• the program first opens the file, reads student’s ids and scores from the file and saves them in two arrays: o create a one-dimensional string array “ids” to store the student’s ids.o create a (parallel) two-dimensional int array “scores” to store student’s original test scores. this array has 5 columns, the original 4 test scores should be saved in the first 4 columns, and the last column will be used to save the average score after the calculation in next step.• the program then retrieves test scores from the array “scores”, calculates average score and determines the final letter grade based on the rules in the table below for each student. assume average score is integer value.average score = (score1 + score2 + score3 + score4) / 4average score letter grade90 ~ 100 a80 ~ 89 b70 ~ 79 c60 ~ 70 d0 ~ 60 f• the average score should be saved back in the 5th column of “scores” array.• create a new parallel one-dimensional char array “grades” to save each student’s letter grade.• program also needs to find the number of a, number of b, number of c, number of d and number of f grade. as well as the highest, lowest and average score of the class.• finally, program will display all of the original scores and all results on the computer screen using the format shown as the sample output below.• the program must contain at least the following functions: (1) a function “getscores” to read and store data into “ids” and “scores” arrays.(2) a function “analyzescores” to calculate student’s average score, determine letter grade, get the number of a, b, c, d and f, find the highest, lowest and average score of the class.(3) a function “displayresults” to display all of the results
