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?

[java] create an application called registrar that has the following classes: a. a student class that minimally stores the following data fields for a student: - name - student id number - number of credits - total grade points earned and this class should also be provides the following methods: - a constructor that initializes the name and id fields - a method that returns the student name field - a method that returns the student id field - methods to set and retrieve the total number of credits - methods to set and retrieve the total number of grade points earned. - a method that returns the gpa (grade points divided by credits) b. an instructor class that minimally stores the following data fields for an instructor: - name - faculty id number - department the following methods should be provided: - a constructor that initializes the name and id fields - methods to set and retrieve the instructor’s department. c. a course class that minimally stores the following data for a course: - name of the course- course registration code- maximum number of 35 students- instructor- number of students- students registered in the course (an array)the following methods should also be provided: - a constructor that initializes the name, registration code, and maximum number of students- methods to set and retrieve the instructor- a method to search for a student in the course; the search should be based on an id number.- a method to add a student to the course. if the course is hill, then an exception with an appropriate message should be raised (try creating your own exception class for this). also, be sure that the student is not already registered in the course. the list of students should be in the order that they registered.- a method to remove a student from the course. if the student is not found, then an exception with an appropriate message should be raised (use the same exception class mentioned a method that will allow course objects to be output to a file using object serialization- a method that will allow course objects to be read in from a file created with object serializationyou will note that the student and instructor classes described above have some commonality. create aperson class that captures this commonality and uses it as a base class for student and instructor. this class should be responsible for the name and id fields and also provide atostring method that returns a string of the form name, id. this will be the inheritedtostring method for the student and instructor classes.1. draw a uml diagram for diss application.2. implement the previous classes in java. write a main program that can serve as a test class that tests all of the methods created and demonstrates that they are working
