A. Array

Which of the following activities in the application lifecycle is used by an architect to create the technical blueprint of a system? a. Requirements analysis b. Design c. Development d. Maintenance

B. Design

You are developing a program that simulates a job processor. Often, the jobs come faster than you can process them, and in such cases, the jobs wait for their turn to be processed. You need to make sure that the job that arrived first is the first to be processed as well. Which of the following data structures is best suited for this requirement? a. Array b. Queue c. Linked list d. Stack

B. Queue

The testers of a software application have access to its source code, and they plan to write test cases that ensure that the methods return correct values. Which of the following testing levels will this activity fall under? a. Integration testing b. Unit testing c. Alpha testing d. Beta testing

B. Unit Testing

You write the following code in a program: int[] numbers = {2, 3, 1, 4}; numbers [2] = 4; What will be the contents of the array after the second statement is executed? a. {2, 4, 1, 4} b. {2, 3, 4, 4} c. {2, 4, 1, 2} d. {4, 3, 1, 4}

B. {2, 3, 4, 4}

The product that you are developing is not yet finished, but you would like to release the product to a wider customer audience for feedback and testing. Under which of the following testing levels would this activity fall? a. Integration testing b. System testing c. Acceptance testing d. Regression testing

C. Acceptance testing

You are developing a program that performs frequent insert and delete operations on the data. The data items need to be accessed like a stack with last-in, first-out functionality. Your solution must require as little memory as possible. Which of the following data structures will best suit these requirements? a. Array b. Circular linked list c. Linked list d. Doubly linked list

C. Linked List

In your application, you are using a queue data structure to manipulate information. You need to find which data item will be processed next, but you don't want to actually process that data item yet. Which of the following queue operations will you use? a. Enqueue b. Dequeue c. Peek d. Contains

C. Peek

You are developing a program that performs frequent insert and delete operations on the data. Your requirement also dictates the capability to access previous and next records when the user presses the previous or next button. Which of the following data structures will best suit your requirements? a. Array b. Circular linked list c. Linked list d. Doubly linked list

D. Doubly linked list

You are developing a program that requires you to track the method calls. You can only invoke one method at a time. However, a method call may in turn invoke other methods. When a method ends, it returns control back to the calling method. Which data structure should you use to keep track of these method calls? a. Queue b. Array c. Linked list d. Stack

D. Stack
