You write the following JavaScript code. Line numbers are included for reference only.
01 < script >
02
03 beststudent = new Student( " David " , " Hamilton " );
04 document.write(beststudent.fullname + " is registered. " );
05 < /script >
You need to write a function that will initialize and encapsulate the member variable fullname.
Which code fragment could you insert at line 02 to achieve this goal?
Note: Each correct answer presents a complete solution.

• A. function Student(firstName, lastName) { firstname = firstName; lastname = lastName; fullname = firstname + " " + lastname;}
• B. function Student(firstname, lastname) { this.firstname = firstname; this.lastname = lastname; this.
  fullname = this.firstname + " " + this.lastname;}
• C. var Student(firstname, lastname) { this.firstname = firstname; this.lastname = lastname; this.fullname = this.firstname + " " + this.lastname;}
• D. var student(firstName, lastName) { firstname = firstName; lastname = lastName; fullname = firstname
  + " " + lastname;}

The development team just released a new version of an app for your team to test. Which three tasks should you perform during testing? Choose 3.

• A. Ask customers to submit feature requests.
• B. Check for syntax errors.
• C. Ask customers to submit bugs or problems.
• D. Check application functionality to ensure it works correctly.
• E. Ensure that the app meets the design specifications.
• F. Find any defects in the app.

You are given the design for an app. The project manager asks you to outline the steps you must take to release and maintain the app.
Move each step from the list on the left to its correct sequence in the application lifecycle on the right.
Note: You will receive partial credit for each correct response.

Explanation:
Determine requirements # Develop code # Test the app
#
Monitor performance # Deploy the app
The correct application lifecycle sequence begins with Determine requirements because the team must first define what the app must accomplish, who will use it, and which functional and technical expectations must be satisfied. Since the question states that the design is already provided, the next implementation step is Develop code, where the HTML, CSS, JavaScript, assets, APIs, and app logic are created according to the approved design and requirements. After development, the app must be validated through Test the app.
Testing confirms that the app works correctly, meets requirements, handles user input properly, and does not contain functional defects that would block release. Once testing is complete, the app can be released through Deploy the app, which publishes it to the target environment or makes it available to users. The final operational stage is Monitor performance, where the released app is observed, maintained, updated, and improved based on performance, reliability, defects, and user behavior.

The following code adds items to the groceries array from the other arrays. Line numbers are for reference only.
01 < body >
02 < p id= " list " > < /p >
03 < script >
04 var groceries = [];
05 var dairy = [ " Milk " , " Eggs " , " Cheese " , " Ice Cream " ];
06 var beverages = [ " Juice " , " Water " , " Soda " , " Coffee " ];
07 var fruits = [ " Apples " , " Bananas " , " Grapes " , " Oranges " , " Strawberries " ];
08 var vegetables = [ " Broccoli " , " Carrots " , " Lettuce " , " Spinach " , " Tomatoes " ];
09 var meats = [ " Beef " , " Chicken " , " Pork " ];
10
11 function addVegetables() {
12 groceries = groceries.concat(vegetables);
13 }
14
15 function addFruits() {
16 groceries = groceries.concat(fruits);
17 }
18
19 function addOther() {
20 groceries.push(meats[1]);
21 groceries.push(dairy[3]);
22 }
23
24 fruits.shift();
25 addVegetables();
26
27 groceries.shift();
28 addFruits();
29
30 groceries.pop();
31 groceries.shift();
32
33 addOther();
34 document.getElementById( " list " ).innerHTML = groceries;
You need to debug the code on the left to determine how many items are in the groceries array at the specified breakpoints.
Evaluate the code and answer the questions by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct answer.

Explanation:
Line 26 drop-down: 5
Line 29 drop-down: 8
Line 32 drop-down: 6
The groceries array starts empty. Line 24 runs fruits.shift(), which removes " Apples " from the fruits array.
This leaves four fruits, but it does not add anything to groceries. Line 25 calls addVegetables(), which executes groceries = groceries.concat(vegetables);. Since vegetables contains five items, groceries contains 5 items at line 26. Line 27 then executes groceries.shift(), removing the first item from groceries and reducing the count to 4. Line 28 calls addFruits(), which appends the four remaining fruits, increasing the array count to 8; therefore, line 29 is 8. Line 30 executes groceries.pop(), removing the last item and reducing the count to
7. Line 31 executes groceries.shift(), removing the first item and reducing the count to 6. Therefore, line 32 is
6. The addOther() function on line 33 has not executed yet at the line 32 breakpoint. References/topics:
