1007ICT Final: 1007ICT_21 Week 3 Weekly Assessment (1)

After successfully completing this assignment, students will be able to:

• Configure, run, and test a linux server in AWS' EC2
• Configure, run, and test a Windows server in AWS' EC2

1. Create an Ubuntu 20 LAMP server in EC2 like we did in class.
2. Verify your that Apache was installed by opening your browser and enter the public dns of your server in the address bar. If it does not connect either you did not add HTTP to the Security Group, or the install did not work properly. Take a screenshot and save it (for submission below).
3. The default location of html and php files is /var/www/html. Change to that directory. Now, using your favorite text editor use sudo to run your editor and create a file in that directory named info.php. For example, sudo nano info.php Then enter the following in that file to show information about the PHP installation: <?php phpinfo(); ?> Save the changes to the file and exit the editor.
4. Now in your browser, enter the public dns of your server in the address bar / info.php. For example, my public dns was ec2-54-89-230-235.compute-1.amazonaws.com, so I enter  as the url. Take a screenshot and save it (for submission below).
5. Create a Windows 2016 Server, like we did in class.  
6. Login to it using Remote Desktop.  Take a screenshot of Remote Desktop connected to your Windows Server and save it (for submission below).

Now that you have completed the assignment, stop or terminate your EC2 instances. Stopping them means that it is now longer running, but your data is saved. That means you will not accrue charges on your running server. Terminating will both stop and delete the instances (also not accruing charges).

• Screenshot of the PHP info page on your server shown in your browser
• Screenshot of Remote Desktop session to your Windows Server

Coding Question - Sorted array You are to write a method that takes as input an array of integers, returns true if the array is sorted, and returns false otherwise. For example, if a is the array {1,12,5,6,2,87}, then the method has to return false as it is not sorted. Use the 5 following questions to "write" your code. Pay close attention to how your answers group together with each other. 33. Line 1 (A) public static boolean Sorted (int[] a) { (B) public static void Sort (int[] a) { (C) public static int[] Sorted (int a) { (D) public static boolean Sorted() { (E) public static void main(String[] s) {

2. In this section you will be shown several classes. Inside the code for each class will be a question. You should provide your answer to the question inside the chart. Many of the questions will ask you whether a variable has changed or not. In cases that the variable being asked about is a primitive type, you should provide your answer based on the data stored in the primitive type. In cases that the variable being asked about is a reference type, you should provide your answer based on the data stored at the Object linked to by the reference type. For example, in the first snippet, the question asks about the variable x defined in the main method. Since x is a primitive type, you should answer YES if you think the variable x has had its value changed after the method methodOne() returns. All your answers should go in the chart below: (9 points) Part Answer to question x changed (circle one)? YES NO y changed (circle one)? a changed (circle one)? b changed (circle one)? d1 a changed (circle one)? b changed (circle one)? YES e words changed (circle one)? YES NO Values in array of array referred to by y: What is printed to the screen? (a) public class ReferenceTesti public static void methodOne (int x){ x++; public static void main(String[args) { int x = 0; methodOne (x); //IS THE DATA STORED OR REFERRED TO BY X THE SAME? (ANSWER IN CHART)
