Assignment 1: Network Consultation for DesignIT

discussion questions

Discussion 1″Ethernet Switches”  Please respond to the following:Since switches are generally used within the local network configuration, why would a network administrator configure port security on a switch? Can you think of a reason based on your study this week? Don’t just give the answer from the materials; cite specific examples from real life. Have fun with it.Discussion 2″Security Administration and Access Control”  Please respond to the following:From the e-Activity, summarize the ethical dilemma, and develop a plan in which you would mitigate the vulnerability. Compare and contrast physical access controls and logical access controls. Further explain in what ways both physical and logical access controls are related to implementing a security policy.e-activityResearch a specific lapse in professional ethics by an IT professional in the last five (5) years.

Disaster Recovery Plan

Week 6 Assignment 1 SubmissionClick the link above to submit your assignment.Students, please view the “Submit a Clickable Rubric Assignment” in the Student Center. Instructors, training on how to grade is within the Instructor Center. Assignment 1: Disaster Recovery PlanDue Week 6 and worth 120 pointsYou are an administrator for the Contoso Corporation. The Contoso Corporation has two (2) large sites. The corporate office is in New York and the manufacturing site is in Cleveland, Ohio. In addition, the Contoso Corporation has five (5) smaller sites. At the Corporate site, you currently have eight (8) physical Hyper-V hosts that host approximately one hundred twenty (120) virtual machines. The virtual machines are running Windows Server 2008 R2 and Windows Server 2012. The servers are needed to host email, various databases, file services, print services, and a point-of sales-application. The virtual machines are stored on a centrally located storage area network (SAN) that has multiple power supplies, and use redundant array of independent disks (RAID).Over the last three (3) years, you have had two (2) power failures that caused the servers to go down at the corporate office. Recently, during one (1) of these incidents, files on one (1) of the servers were corrupted. It was later discovered that the backup could only partially restore the data files, but could not restore the server itself.The servers must remain available and reliable. As the administrator, you must ensure that you can recover from a failure or problem quickly with minimum loss. Write a three to five (3-5) page paper in which you:Develop a continuity plan / disaster recovery plan for Contoso Corporation in which you address the following:Suggest an approach that provides redundancy (failover) for all mission critical functions in the event of a disaster including power failure. Consider the following in your approach: Essential Infrastructure; Email; Database; File Services; Print Services; Point-of-Sale Applications; Power Redundancy Solutions.Identify the changes that should be made to the backup procedures in order to address the problem with the server backups.Outline the necessary actions that Server Administrators must verify for proper operation of servers in the event of a failover.Provide a plan for returning all services back to the primary systems once the crisis has passed.Examine the pros and cons of moving part of the data center to the Cleveland office and housing it there on a permanent basis. Provide your recommendation for the stated action. Your assignment must follow these formatting requirements:Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.The specific course learning outcomes associated with this assignment are:Demonstrate the ability to describe, manage, and configure load balancing and failover clustering.Demonstrate the ability to configure and manage backups to include role-specific and online or cloud environments.Demonstrate the ability to recover servers to include files and volumes.Use technology and information resources to research issues in advanced network infrastructure environments.Write clearly and concisely about advanced network infrastructure topics using proper writing mechanics and technical style conventions

Write a java application that defines a Circle and a Rectangle and prints the area of each.  Make use of encapsulation to defined class attributes and methods.A circle has three attributes: center Point, radius, and area.  Use a proper constructor to initialize Circle object.  To initialize a circle, you will need a center point and a radius. Then, you can use the radius to calculate the area of a circle.  The area of a circle is calculated using the following equation (PI = 3.14):Area = PI * radius * radiusA Rectangle consists of four Points which are the upper left, upper right, lower left, and lower right corner points, length, height, and area.  To initialize a rectangle, you will need the coordinates of all four corner points from which you can calculate the length, the height, and the area of a rectangle. The area of a rectangle is calculated using the following equation (Note that length is the distance between the upper left and upper right corner points and height is the distance between the upper left and lower left corner points):Area = length * heightThe Point class defines the X and Y coordinates of a point.  The distance between two points is calculated using the following equation:Distance = sqrt((x2 – x1)^2 + (y2 – y1)^2)For each class define displayInfo( ) method that would output information about an object.  You can use the following main method to test your application.  A sample output of the application is also shown below.public class ShapeApp {    public static void main(String[] args) {         Point upperLeft = new Point(1, 5);        Point lowerLeft = new Point(1, 1);        Point upperRight = new Point(5, 5);        Point lowerRight = new Point(5, 1);        Rectangle r1 = new Rectangle(upperLeft, upperRight, lowerLeft,lowerRight);        r1.display();        Point center = new Point(10,10);        int radius = 4;        Circle c1 = new Circle(center, radius);        c1.display();    }}===================    SAMPLE OUTPUT =========================Rectangle Info:Upper Left Point (x,y) : 1,5Upper Right Point (x,y): 5,5Lower Left Point (x,y) : 1,1Lower Right Point (x,y): 5,1area                   : 16.0Circle Info:Center Point (x,y) : 10,10Radius             : 4area               : 50.24
