Your organization needs to retain a legacy application for the Inventory department. Next year, a new application will be purchased, and all the current data will be exported to the new application at that time. For the time being, you have been asked to retain the legacy application. The computer on which the legacy application resides can no longer be supported and must be removed from the
enterprise. You have been asked to implement a solution that allows the legacy application to remain in use. What should you do?
A. Deploy the legacy application on its own VLAN.
B. Deploy the legacy application on a virtual machine.
C. Deploy the legacy application on the DMZ.
D. Deploy the legacy application on a public cloud.
B
Explanation: You should deploy the legacy application on a virtual machine. This ensures that the legacy application is still supported while ensuring that the computer that it is on can be removed from the enterprise.
None of the other options will provide the same level of support and security as the virtual machine option.

Write an application that will test the user’s knowledge of road signs. Your application should display a random sign image and ask the user to select the sign name from a JComboBox. This application should look like Fig. 16.43. [Hint: The application is similar to the Flag Quiz application.] You can find the road sign images in C:\Examples\Tutorial16\Exercises\RoadSignTest\images.
a) Copying the template to your working directory. Copy the C:Examples Tutorial16ExercisesRoadSignTest directory to your C:SimplyJava directory.
b) Opening the template file. Open the RoadSignTest.java file in your text editor.
c) Declaring an array to contain the user’s options. On lines 29–33, create String array signs (use line 29 for a comment and lines 30–33 to declare and initialize the array). Have the array contain the values "Do Not Enter", "Narrow Bridge", "No Bicycles", "No Left Turn", "No Pedestrians", "No U-turn", "Road Narrows", "Stop", "Stop Sign Ahead", "Traffic Signals Ahead", "Winding Road Ahead" and "Yield".
d) Declaring an array to store which signs are used. On lines 35–36, create a boolean array named signsUsed (use line 35 for a comment and line 36 to create the array). Specify the array to be of size 12.
e) Sorting array signs. On line 73, sort array signs alphabetically.
f) Customizing signJComboBox. Modify line 76 so that signJComboBox
