Answer:
No programming language stated; I'll answer this question using Python.
(Please note that -> at the last line means indentation)
The program is as follows:
num1 = float(input("Number 1: "))
num2 = float(input("Number 2: "))
num3 = float(input("Number 3: "))
result = (num1 + num2 + num3)/2
print("Result: ",result)
if result > 6:
->print("Your result is more than 6!")
Explanation:
The first three lines prompt the user for input of 3 numbers (the number could be decimal, whole numbers, positive or negative numbers)
num1 = float(input("Number 1: "))
num2 = float(input("Number 2: "))
num3 = float(input("Number 3: "))
The next line sums up user input and divides the sum by 2
result = (num1 + num2 + num3)/2
The next line prints the calculated result in the previous line
print("Result: ",result)
The next line determines if the calculated result is more than 6; if yes, the associated print statement is executed
if result > 6:
->print("Your result is more than 6!")
Once again, please note that -> at the last line means indentation
The blank function returns to the first character or characters in a text string based on the number of characters specified??? A. PROPER B. MID C. LEN D. LEFT
Answer: D.) LEFT
Explanation: LEFT is an excel function allows users to extract a specified number of characters starting from the left. The syntax goes thus :
=LEFT(text, [num_chars])
text: the original string in which characters are to be extracted.
num_chars : takes an integer, stating the number of characters to extract.
The proper function is also an excel function which sets the first character in each word to uppercase. The mid function is also used in text extraction starting from any position in the original string based on what is specified.
The LEN function is used to get the number or length of characters in a string.

What happens if two functions are defined with the same name, even if they are in different arguments within the same .py files?
Answer:
Following are the code to this question:
def data(a):#defining method data that accepts parameter
print (a)#print parameter value
def data(b):#defining method data that accepts parameter
print (b)#print parameter value
x=input("enter value: ")#defining variable x that5 input value from user

Explanation:
As the above code, it is clear defines that python doesn't support the method overloading because More than one method can't be specified in a python class with the same name and python method arguments have no type. The single argument method may be named using an integer, a series, or a double value, that's why we can say that it is not allowed.What is computer engineering in your own words?

Open the Undergrad Debt data in the Excel file. Nationally, on average, a college student last year graduated with $27,200 in debt with a historical standard deviation of $5,000. The file gives sample date from Arkansas.
Does Arkansas students have higher debt than the national average at alpha equal to 10?
Answer:
Arkansas students have higher debt than the national average, $27,200.
Explanation:
The provided data is:
S = {24040, 19153, 26762, 31923, 31533, 34207, 14623, 24370, 31016}
In this case we need to test whether Arkansas students have higher debt than the national average at alpha equal to 0.10.
The hypothesis can be defined as follows:
H₀: Arkansas students does not have higher debt than the national average, i.e. μ ≤ $27,200.
Hₐ: Arkansas students have higher debt than the national average, i.e. μ > $27,200.
Compute the sample mean:
[tex]\bar x=\frac{1}{n}\sum X=\frac{1}{10}\times 213537=21353.70[/tex]
As the population standard deviation is provided, we will use a z-test for single mean.
Compute the test statistic value as follows:
[tex]z=\frac{\bar x-\mu}{\sigma/\sqrt{n}}=\frac{21353.70-27200}{5000/\sqrt{10}}=-3.70[/tex]
The test statistic value is -3.70.
Decision rule:
If the p-value of the test is less than the significance level then the null hypothesis will be rejected.
Compute the p-value for the test as follows:
[tex]p-value=P(Z>-3.70)=P(Z<-3.70)=0.00011[/tex]
*Use a z-table for the probability.
The p-value of the test is 0.00011.
p-value = 0.00011 < α = 0.10
The null hypothesis will be rejected.
Thus, it can be concluded that Arkansas students have higher debt than the national average, $27,200.

zybooks cis 110 challenge activity 9.8.1 Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order. Ex: If the input is 6, the output is 011. Your program should define and call a function: Function Integer To Binary(integer num) returns nothing The function should output 1's and 0's representing the integer in binary (in reverse).
Answer:
public class IntegerToBinary
{
public static void main(String[] args) {
integerToBinary(6);
}
public static void integerToBinary(int num){
while(num > 0){
System.out.print(num%2);
num = Math.floorDiv(num, 2);
}
}
}
Explanation:
*The code is in Java.
Create a function called integerToBinary that takes one parameter, num
Inside the function, create a while loop that iterates while the num is greater than 0. Inside the loop, print the num%2. Then, get the floor division of the num by to and assign it to the num.
Inside the main, call the function with parameter 6.
Create a program that will find and display the largest of a list of positive numbers entered by the user. The user should indicate that he/she has finished entering numbers by entering a 0.
Answer:
This program is written using Python Programming language,
The program doesn't make use of comments (See explanation section for line by line explanation)
Program starts here
print("Enter elements into the list. Enter 0 to stop")
newlist = []
b = float(input("User Input: "))
while not b==0:
newlist.append(b)
b = float(input("User Input: "))
newlist.sort()
print("Largest element is:", newlist[-1])
Explanation:
This line gives the user instruction on how to populate the list and how to stop
print("Enter elements into the list. Enter 0 to stop")
This line creates an empty list
newlist = []
This line enables the user to input numbers; float datatype was used to accommodate decimal numbers
b = float(input("User Input: "))
The italicized gets input from the user until s/he enters 0
while not b==0:
newlist.append(b)
b = int(input("User Input: "))
This line sorts the list in ascending order
newlist.sort()
The last element of the sorted list which is the largest element is printed using the next line
print("Largest element is:", newlist[-1])
Write a date transformer program using an if/elif/else statement to transform a numeric date in month/day format to an expanded US English form and an international Spanish form; for example, 2/14 would be converted to February 14 and 14 febrero

day = split_date[1]
if month == '1':
english_month = 'January'
spanish_month = 'Enero'
elif month == '2':
english_month = 'February'
spanish_month = 'Febrero'
elif month == '3':
english_month = 'March'
spanish_month = 'Marzo'
elif month == '4':
english_month = 'April'
spanish_month = 'Abril'
elif month == '5':
english_month = 'May'
spanish_month = 'Mayo'
elif month == '6':
english_month = 'June'
spanish_month = 'Junio'
elif month == '7':
english_month = 'July'
spanish_month = 'Julio'
elif month == '8':
english_month = 'August'
spanish_month = 'Agosto'
elif month == '9':
english_month = 'September'
spanish_month = 'Septiembre'
elif month == '10':
english_month = 'October'
spanish_month = 'Octubre'
elif month == '11':
english_month = 'November'
spanish_month = 'Noviembre'
elif month == '12':
english_month = 'December'
spanish_month = 'Diciembre'
US_English = f'{english_month} {day}'
International_Spanish = f'{day} {spanish_month}'
print(f'US English Form: {US_English}')
print(f'International Spanish Form: {International_Spanish}')
Input:
3/5
Output:
US English Form: March 5
International Spanish Form: 5 Marzo
Explanation:
You start by taking input from the user then splitting that at the '/' so that we have the date and the month in separate variables. Then we have an if statement checking to see what month is given and when the month is detected it sets a Spanish variable and an English variable then prints it to the screen.
Hope this helps.
Your mission is to read this uber-classified memo from the Grand Poobah of annan. Of course, it's in code, so you'll need to write a program to decrypt your message. The code is set up so that for the nth element in the array, you will need to read its nth letter. (Ex: if pirates is in array position 0, then print letter 0 of the word, which = p. if gangway is in array position 4, then print letter 4 = w.) To accomplish this, your main function should do the following: a. Declare 4 separate arrays of strings called secrets1, secrets2, secrets3, & secrets4 and assign them the following values: secrets1: { "platypus", "plethora","trend", "croak","almost", "toaster" }; secrets2: _{ "fire", "seen","trend", "produce" }; secrets3: { "tiretread", "chains", "stern", "bed bug" }; secrets4: {"oracle", "stetson","mother", "stie", "twigrot" }; b. Call the function decode 4 times - once for each array variable (secrets1, secrets2, secrets3 & secreets4) from Step a. (You'll have to do this with 4 lines of code; you can't use a loop for it.) c. Write a void function called decode that will i. Accept an array of strings, and the integer array length as the parameters. ii. Read through each word in the array. If the word is in the nth position of the array, then print the nth letter for that word. (For array item 0, print the letter at position 0 in the word. For array item 1, print the letter at position 1 in the word...etc.) Print all of the letters from this array on one line. iii. Print a blank
Answer:
Following are the code to this question:
#include<iostream>//declaring header file
using namespace std;
void decode(string* arr, int n)//defining a method decode
{
for(int i = 0; i < n; i++)//defining a loop for print value
{
cout << arr[i][i] << " "; // using print method to print ith letter of the string
}
cout << endl;//line break
}
int main()//defining main method
{
string secret1[] = {"platypus","plethora","trend","croak","almost","toaster"};//defining string arry and assign value
string secret2[] = {"fire","seen","trend","produce"};//defining string arry and assign value
string secret3[] = {"tiretread","chains","stern","bed bug"};//defining string arry and assign value
string secret4[] = {"oracle","stetson","mother","stie","twigrot"};//defining string arry and assign value
decode(secret1, 6);//calling method decode and pass string array and integer number
decode(secret2, 4);//calling method decode and pass string array and integer number
decode(secret3, 4);//calling method decode and pass string array and integer number
decode(secret4, 5);//calling method decode and pass string array and integer number
return 0;
}
output:
Please find the attachment.
Explanation:
In the above C++ language code, a method "decode" is declared that accepts a string array and an integer variable in its parameter, inside the method a for loop is declared, which is used "n" variable to print its [tex]i^{th}[/tex] letter value in the given string value.
In the main method, 4 string array "secret1, secret2, secret3, and secret4" is declared which assigns some value, and then we call the method "decode" and pass string array value and an integer value in its parameter.

It is always possible and feasible for a programmer to come up with test cases that run through every possible path in a program.
A. True
B. False
Answer:
True
Explanation:
It is always possible and feasible for a programmer to come up with test cases that run through every possible path in a program is a "true statement" or the first option. It is very natural for a programmer/developer to come up with test that will run through every possible outcome in a program. Doing so will help the developer find things that might cause problems with the program in later time.
Hope this helps.
The answer to the question about the feasibility of a programmer to always come up with test cases that run through every possible path in a program is:
NoWhat is a Test Case?This refers to the set of actions which a programmer performs to find out if his software or program passes the system requirements in order to work properly.
With this in mind, we can see that while in some cases, it is possible for the programmer to come up with test cases, but it is not feasible in all cases as there can be hardware error which a virtual machine cannot solve.

Write a Java application with a main() to find the two largest distinct integers entered on the command line by the user. We are just creating a simple stand-alone application. All your code can be in main().
Answer:
import java.util.Scanner; // Scanner class is to use input output functions
public class TwoDistinctLargest //class to find two distinct largest nos
{
public static void main(String[] args) { //start of main() function
Scanner input = new Scanner(System.in); // creates Scanner type object
int integers = 0, largest1 = 0, largest2 = 0; // declare variables
/* integers holds the input integer values, largest1 has 1st largest number and largest 2 contains second distinct largest number, i is used as the count variable to move through the input integers */
int i = 0;
//prompts user to enter integers and enter 0 to stop
System.out.println("Enter the integers (press 0 to stop): ");
integers = input.nextInt(); //reads and scans input integers
while(integers != 0) {
/* the loop keeps taking integer values from user until the value of integers is equal to 0, this means until the user enters 0 */
//checks if the value of integer is greater than first largest computed number
if(integers > largest1) {
//if the value in largest1 is greater than that of largest2
if(largest1 > largest2) {
largest2 = largest1; } // then value of largest1 is set to largest2
largest1 = integers; // largest1 now holds the value of integers //which means largest1 holds the first distinct largest integer
} else { //checks if the value of integers is greater than largest2
if(integers > largest2) {
//if the value of integers is not equal to that of largest1
if(integers!=largest1) {
// set the value of second distinct largest number to largest2
largest2 = integers;} } }
i++; //keeps moving to the next input integer
integers = input.nextInt(); //keeps taking input integers }
//prints the two distinct largest integers
System.out.println("\n The 1st largest distinct integer is " + largest1);
System.out.println("\n The 2nd largest distinct integer is " + largest2); } }
Explanation:
Lets suppose the user inputs the following integers
1, 6, 5, 6, 0
Initial values are:
integers = 0
largest1 = 0
largest2 = 0
i = 0
When the user enters 1, then value of integers = 1
while loop checks if integers!=0. As integers =1 so the program enters the body of while loop. The first IF condition is checked if(integers > largest1)
As largest1 = 0 and integers =1 so this condition evaluates to true as 1 > 0
So the statements in the body of this IF condition are executed. This if conditions contains another if statement if(largest1 > largest2) which checks if the value largest1 is greater than that of largest2. Its false because largest1 =0 and largest2 =0 so largest1 = largest2, so the statement of this if condition body will not execute and program moves to this largest1 = integers; statement which sets the value of integers i.e. 1 to largest1. So the value of largest1 = 1
Now the i is incremented by 1 and it points at second value of integers= 6.
while loop checks if integers!=0. As integers =6 so the program enters the body of while loop. The first IF condition is checked if(integers > largest1)
As largest1 = 1 and integers =6 so this condition evaluates to true as 6>1
So the statements in the body of this IF condition are executed. This if conditions contains another if statement if(largest1 > largest2) which checks if the value largest1 is greater than that of largest2.
Its true because largest1 =1 and largest2 =0 so largest1 > largest2, so the next statement is executed largest2 = largest1; So now the value of largest2=1.
Now program moves to this largest1 = integers; statement which sets the value of integers i.e. 6 to largest1. So the value of largest1 = 6
Now the i is incremented by 1 and it points at second value of integers= 5.
while loop condition is again true. IF condition is checked if(integers > largest1)
As largest1 = 6 and integers =5 so this condition evaluates to false as 5<6. So this IF part will not execute and program control moves to the else part.
Else part has an if condition if(integers > largest2) which evaluates to true because integers = 5 and largest2 = 1 so the program moves to next if statement inside the previous if statement of else part i.e. if(integers!=largest1). This if statement is the main statement which will help in finding two distinct largest numbers in case the same largest value is input more than once. It checks If the value of integers is not equal to largest1 value. As integers = 5 and largest1 = 6 so this if condition is true. If this condition is not used in this program then largest2 will not be assigned distinct largest values but assigned 6 for both largest1 and largest2 as 6 is input twice. Next this if statement largest2 = integers assigns value of integers to largest2 which is the second largest distinct integer.
Now the i is incremented by 1 integers value become 0.
while loop checks if integers!=0. As integers =0 so the while loop breaks. The last two print statements which produce following output.
The 1st largest distinct integer is: 6
The 2nd largest distinct integer is: 5

Suppose that a main method encounters the statement t3.join(); Suppose that thread t3's run() method has completed running. What happens?
A. The main method waits for all running threads to complete their run() methods before proceeding.
B. The main method waits for any other thread to complete its run() method before proceeding
C. The main method proceeds to the next statement following the t3.join(); statement
D. Thread t 3 is re-started
E. All threads except t3 that are running are terminated
Answer:
C. The main method proceeds to the next statement following the t3.join(); statement
Explanation:
join() method allows the thread to wait for another thread and completes its execution. If the thread object is executing, then t3.join() will make that t is terminated before the program executes the instruction. Thread provides the method which allows one thread to another complete its execution. If t is a thread object then t.join() will make that t is terminated before the next instruction. There are three overloaded functions.
join()
join(long mills)
join(long millis, int Nanos)
If multiple threads call the join() methods, then overloading allows the programmer to specify the period. Join is dependent on the OS and will wait .
Write the definition of the function displaySubMenu that displays the following menu; this function doesn't collect the user's input; only display the following menu:
[S]top – Press 'S' to stop.
Answer:
Using Python:
def displaySubMenu():
print("[S]top – Press ‘S’ to stop.")
Using C++ programming language:
void displaySubMenu(){
cout<<"[S]top – Press ‘S’ to stop.";}
Explanation:
The function displaySubMenu() has a print statement that prints the following message when this function is called:
[S]top – Press 'S' to stop.
You can invoke this function simply by calling this function as:
displaySubMenu()
The function doesn't take any input from the user and just displays this message on output screen whenever this function is called.
In C++ you can simply call the function using following statement:
void main(){
displaySubMenu(); }
var name = prompt("Enter the name to print on your tee-shirt");
while (name.length > 12) {
name = prompt("Too long. Enter a name with fewer than 12 characters.");
}
alert("The name to be printed is " + name.toUpperCase());
What will happen if the user enters Willy Shakespeare at the first prompt?
a. The user will be prompted to enter a different name
b. The alert will display The name to be printed is " + name.toUpperCase()
c. The alert will display The name to be printed is WILLY SHAKESPEARE
d. The alert will display The name to be printed is WILLY SHAKES
Willy Shakespeare has 17 characters. It's higher than 12,so the output will be Too long. Enter a name with fewer than 12 characters.

Write a program that first reads in the name of an input file and then reads the file using the csv.reader() method. The file contains a list of words separated by commas. Your program should output the words and their frequencies (the number of times each word appears in the file) without any duplicates.
Answer:
Here is the Python code.
import csv
inputfile = input("Enter name of the file: ")
count = {}
with open(inputfile, 'r') as csvfile:
csvfile = csv.reader(csvfile)
for line in csvfile:
for words in line:
if words not in count.keys():
count[words] = 1
else:
count[words] + 1
print(count)
Explanation:
I will explain the code line by line.
import csv here the css is imported in order to read the file using csv.reader() method
inputfile = input("Enter name of the file: ") This statement takes the name of the input file from the user
count = {} this is basically a dictionary which will store the words in the file and the number of times each word appears in the file.
with open(inputfile, 'r') as csvfile: This statement opens the inputfile using open() method in read mode. This basically opens the input file as csv type
csvfile = csv.reader(csvfile) This statement uses csv.reader() method to read the csv file contents.
for line in csvfile: This outer for loop iterates through each line of the file
for words in line: This inner loop iterates through each word in the line
if words not in count.keys(): This if condition checks if the word is not in the dictionary already. The dictionary holds key value pair and keys() method returns a list of all the keys of dictionary
count[words] = 1 if the word is not present already then assign 1 to the count dictionary
co unt[words] + 1 if the word is already present in dictionary increment count of the words by 1. Suppose the input file contains the following words:
hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy
Then because of co unt[words] + 1 statement if the word appears more than once in the file, then it will not be counted. So the output will be:
{' cat': 1, ' man': 1, ' dog': 1, ' woman': 1, ' Hello': 1, ' hey': 1, ' boy': 1, 'hello': 1, ' Cat': 1}
But if you want the program to count those words also in the file that appear more than once, then change this co unt[words] + 1 statement to:
count[words] = count[words] + 1
So if the word is already present in the file its frequency is increased by 1 by incrementing 1 to the count[words]. This will produce the following output:
{' Cat': 1, ' cat': 2, ' boy': 2, ' woman': 1, ' dog': 2, ' hey': 2, ' man': 2, ' Hello': 1, 'hello': 1}
You can see that cat, boy, dog and hey appear twice in the file.
print(count) This statement prints the dictionary contents with words and their frequencies.
The program with its output is attached.
The program is an illustration of file manipulations.
File manipulations involve reading from and writing into files.
The program in Python, where comments are used to explain each line is as follows:
#This imports csv module
import csv
#This initializes a dictionary
kounter = {}
#This gets input for the file name
fname = input("Filename: ")
#This opens and iterates through the file
with open(fname, 'r') as cfile:
#This reads the csv file
cfile = csv.reader(cfile)
#This iterates through each line
for line in cfile:
#This iterates through each word on each line
for words in line:
#This counts the occurrence of each word
if words not in kounter.keys():
kounter[words] = 1
else:
kounter[words] + 1
#This prints the occurrence of each word
print(kounter)

A TCP scanning/probe involves sending a number of packets to each port that is scanned. when you Compare TCP scanning methods to other methods of scans, a TCP Connect scan is typically slow and methodical.
If no other row matches, the router will select the ________ row as its best match. First Last either First or Last, depending on the circumstances neither First nor Last
Answer:
Last
Explanation:
Routing is a term in engineering which involves the process of selecting a path for traffic in a network or across multiple networks. It is applicable in circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. It is mostly used as a term for IP Routing.
Hence, in IP Routing, the first step is comparing the packet's destination IP address to all rows, followed by selecting the nest-match row. However, If no other row matches, the router will select the LAST row as its best match.
A bank in your town updates its customers’ accounts at the end of each month. The bank offers two types of accounts: savings and checking. Every customer must maintain a minimum balance. If a customer’s balance falls below the minimum balance, there is a service charge of $10.00 for savings accounts and $25.00 for checking accounts. If the balance at the end of the month is at least the minimum balance, the account receives interest as follows:
a. Savings accounts receive 4% interest.
b. Checking accounts with balances of up to $5000 more than the minimum balance receive 3% interest; otherwise, the interest is 5%.
This Java program using Eclipse Indigo reads a customer’s account number ( int type ), account type ( char type; s or S for savings, c or C for checking), minimum balance that the account should maintain, and current balance. The program should then output the account number, account type, current balance, and new balance or an appropriate error message. Test program by running it five times, using the following data:
46728 S 1000 2700
87324 C 1500 7689

The IP protocol (and UDP) are called "connectionless" and "unreliable." Describe what those two words mean in the context of data communications?
Answer:
Explanation:
In data communications, a protocol is connectionless if it describes communication between two devices in a network without first establishing or verifying establishment of some link (connection) between the two devices. In a connectionless protocol, data are exchanged between processes or devices without a prior check of whether the processes are ready to transmit data or not. In this type of protocol, there's no verification put in place to remember if these processes were or are in communication. Connectionless protocols are also called stateless protocols. Because connectionless protocol cannot be relied upon due to its lack of delivery-assurance policy, it is sometimes referred to as unreliable protocol. In other words, delivery of data packets is not guaranteed. An example of a connectionless protocol is the UDP (User Datagram Protocol).
However, if the protocol defines some checks to ascertain that there is first a connection between two communicating processes before beginning transmission, then, the protocol is connection-oriented. An example of this is the TCP (Transmission Control Protocol). Connection-oriented protocols are reliable since they ensure connection be made between processes before transmitting data packets.
A typical application of a connectionless/unreliable protocol is in the streaming of real time videos or voice communication where packets of data could be dropped and not resent.
An example of the connection-oriented/reliable protocol is analogous to making a telephone call where data packets (voice messages) are not sent until the receiver on the other end makes a connection.
In cell B13, create a formula using the VLOOKUP function that looks up the value from cell A11 in the range A5:B7, returns the value in column 2, and specifies an exact match.
Answer:
VLOOKUP(A11,A5:B7,2,0) is the correct answer to this question.
Explanation:
The VLOOKUP method contains a vertical lookup by scouring for worth in a table's first section and trying to return the significance in the throughout the situation within the same row. The VLOOKUP excel is a built-in function classified as a Lookup / see as.
According to the question:-
The formulation needed to enter is = VLOOKUP(A11, A5: B7,2,0)
The first "A11" here is the cell from which value is retrieved
The second "A5: B7" input is the range for the table where you need to lookup. 2 Is the number of the column from which the value is taken and 0 indicates the exact math
The VLOOKUP function is used to look up a value in a particular column.
The VLOOKUP formula to enter in cell B13 is: VLOOKUP(A11,A5:B7,2,0)
The syntax of a VLOOKUP function is:
VLOOKUP(lookup_value, cell_range, column_index, [return_value])
Where:
lookup_value represents the value to look upcell_range represents the cells to checkcolumn_index represents the column index[return_value] is an optional entry, and it represents the value that will be returned by the look up function.From the question, we have:
lookup_value = cell A11cell_range = cell A5 to B7column_index = 2[return_value] = 0So, the VLOOKUP function would be: VLOOKUP(A11,A5:B7,2,0)

Consider the following algorithm. x â 1 for i is in {1, 2, 3, 4} do for j is in {1, 2, 3} do x â x + x for k is in {1, 2, 3, 4, 5} do x â x + 1 x â x + 5 Count the number of + operations done by this algorithm.
Answer:
Number of + operation done by this algorithm is 60
Explanation:
i = 4
j = 3
k = 6
Now, let "n" be number of '+' operations
n = i × j + i × 2k
substituting the figures
n = 4 × 3 + 4 × (2 × 6)
n = 12 + 4 × 12
n = 12 + 48
n = 60

What is the value of the totalsString variable after the following code is executed? var totals = [141.95, 212.95, 411, 10.95]; totals[2] = 312.95; var totalsString = ""; for (var i = 0; i < totals.length; i++) { totalsString += totals[i] + "|"; }
141.95|212.95|312.95|10.95|
Explanation:Reformatting the code snippet and giving it line numbers;
1. var totals = [141.95, 212.95, 411, 10.95];
2. totals[2] = 312.95;
3. var totalsString = "";
4. for (var i = 0; i < totals.length; i++) {
5. totalsString += totals[i] + "|";
6. }
Line 1 creates an array called totals with four elements.
First element = totals[0] =141.95
Second element = totals[1] = 212.95
Third element = totals[2] = 411
Fourth element = totals[3] = 10.95
Line 2 replaces the value of the third element totals[2] = 411 with 312.95.
Therefore the array totals = [141.95, 212.95, 312.95, 10.95]
Line 3 creates an empty string called totalsString
Lines 4 - 6 create a for loop that cycles from i=0 to i<totals.length
totals.length = 4 (which is the number of items in the array totals)
This means that the loop cycles from i=0 to i<4
During cycle 1 when i = 0, the expression inside the for loop executes as follows;
totalsString = totalsString + totals[0] + "|" //substitute the values
totalsString = "" + 141.95 + "|"
totalsString = 141.95|
During cycle 2 when i = 1, the expression inside the for loop executes as follows;
totalsString = totalsString + totals[1] + "|" //substitute the values
totalsString = "141.95|" + 212.95 + "|"
totalsString = 141.95|212.95|
During cycle 3 when i = 2, the expression inside the for loop executes as follows;
totalsString = totalsString + totals[2] + "|" //substitute the values
totalsString = "141.95|212.95|" + 312.95 + "|"
totalsString = 141.95|212.95|312.95|
During cycle 4 when i = 3, the expression inside the for loop executes as follows;
totalsString = totalsString + totals[3] + "|" //substitute the values
totalsString = "141.95|212.95|312.95|" + 10.95 + "|"
totalsString = 141.95|212.95|312.95|10.95|
At the end of the execution, totalsString = 141.95|212.95|312.95|10.95|

Which of the following would BEST secure the internal network and allow access to the needed servers?
A. Implementing a site-to-site VPN for server access.
B. Implementing a DMZ segment for the server
C. Implementing NAT addressing for the servers
D. Implementing a sandbox to contain the servers
Answer:
(B) Implementing a DMZ segment for the servers
Explanation:
DMZ is the short form for Demilitarized Zone. It is the temporary storage between an internal or private LAN and the public Internet. The main purpose of the DMZ is to give additional layer of security to a company's LAN (Local Area Network).
Once there are services to be provided to users on the public Internet, such services should be added to the DMZ. A few services that are worth implementing a DMZ segment for are;
i. Email servers
ii. Web servers
iii. Proxy servers
iv. FTP servers
