Answer:
The scores array: 70,20,35,15,40
Explanation:
I will explain the code line by line:
var scores = [70, 20, 35, 15];
The above statement declares and assigns values to an array named scores
scores[scores.length] = 40;
The above statement uses length to set the length of the scores array. It sets the last element of the scores array to 40. So this means 40 is set as the last element of scores.
scores.length returns the length of the scores array i.e. 4 as there are 4 elements in scores array 70,20,35,15
So the statement becomes:
scores[4] = 40;
This assigns value 40 to the 4th index of the scores array. Do not confuse 4th index with 4th element of the array because array element location starts from 0. So scores[4] does not mean 4th element but scores[4] means 4th index position of scores array. This makes 5th element of scores. So set the element 40 as 5th element at 4th index of scores.
alert("The scores array: " + scores);
This displays an alert box with the following message:
The scores array: 70,20,35,15,40

Description:
Create a program that converts the number of miles that you walked on a hike to the number of feet that you walked.
Console:
Hike Calculator
How many miles did you walk?: 4.5
You walked 23760 feet.
Continue? (y/n): y
How many miles did you walk?: 2.5
You walked 13200 feet.
Continue? (y/n): n
Bye!
Specifications:
The program should accept a float value for the number of miles.
Store the code that gets user input and displays output in the main function.
There are 5280 feet in a mile.
Store the code that converts miles to feet in a separate function. This function should return an int value for the number of feet.
Assume that the user will enter a valid number of miles.
Answer:
The programming language is not stated (I'll answer using C++)
#include <iostream>
using namespace std;
int convert(float miles)
{
return miles * 5280;
}
int main() {
cout<<"Console:"<<endl;
cout<<"Hike Calculator"<<endl;
float miles;
char response;
cout<<"How many miles did you walk?. ";
cin>>miles;
cout<<"You walked "<<convert(miles)<<" feet"<<endl;
cout<<"Continue? (y/n): ";
cin>>response;
while(response == 'y')
{
cout<<"How many miles did you walk?. ";
cin>>miles;
cout<<"You walked "<<convert(miles)<<" feet"<<endl;
cout<<"Continue? (y/n): ";
cin>>response;
}
cout<<"Bye!";
return 0;
}
Explanation:
Here, I'll explain some difficult lines (one after the other)
The italicized represents the function that returns the number of feet
int convert(float miles)
{
return miles * 5280;
}
The main method starts here
int main() {
The next two lines gives an info about the program
cout<<"Console:"<<endl;
cout<<"Hike Calculator"<<endl;
float miles;
char response;
This line prompts user for number of miles
cout<<"How many miles did you walk?. ";
cin>>miles;
This line calls the function that converts miles to feet and prints the feet equivalent of miles
cout<<"You walked "<<convert(miles)<<" feet"<<endl;
This line prompts user for another conversion
cout<<"Continue? (y/n): ";
cin>>response;
This is an iteration that repeats its execution as long as user continue input y as response
while(response == 'y')
{
cout<<"How many miles did you walk?. ";
cin>>miles;
cout<<"You walked "<<convert(miles)<<" feet"<<endl;
cout<<"Continue? (y/n): ";
cin>>response;
}
cout<<"Bye!";

A security engineer has been asked to recommend a system that will aggregate data and provide metrics that will assist in identifying malicious actors or other anomalous activity throughout the environment. Which of the following solutions should the engineer recommend?a. Web application firewall b. SIEM c. IPS d. UTM e. File integrity monitor
Answer:
b. SIEM.
Explanation:
In this scenario, an organization is struggling to differentiate threats from normal traffic and access to systems. A security engineer has been asked to recommend a system that will aggregate data and provide metrics that will assist in identifying malicious actors or other anomalous activity throughout the environment. The solution the engineer should recommend is the Security information and event management (SIEM).
Security information and event management is an enterprise software that provides a holistic view and analyzes activity from various resources across an entire information technology (IT) infrastructure.
The SIEM is used to aggregate important data from multiple source such as servers, routers, firewall, switches, domain controllers, antivirus software and analyzes the data to detect any threat, deviation from the norm, as well as investigate in order to take appropriate actions. Some examples of the SIEM system are IBM QRadar, Splunk, LogRhythm etc.

What-If Analysis in Excel allows you to try out different values (scenarios) for formulas. The following example helps you master what-if analysis quickly and easily.
Assume you own a book store and have 100 books in storage. You sell a certain % for the highest price of $50 and a certain % for the lower price of $20.
(i really hope this is what u needed)
1| def saveUserProfile(firstName, lastName, age, height, country):
2| filename = lastName + firstName + ".txt"
3| outputFile = open(filename, "w")
4| print(lastName, file = outputFile)
5| print(firstName, file = outputFile)
6| print(country, file = outputFile)
7| print(height, file = outputFile)
8| print(age, file = outputFile)
9| outputFile.close()
Above is a function that takes five pieces of information about a user and saves that data to a file. We'll assume firstName, lastName, and country are strings, age is an integer, and height (expressed in meters) is a float.
Assume we call the function above with this line of code:
saveUserProfile("David", "Joyner", 30, 1.8, "USA")
After the function runs, what is name of the file that is created?
a. What is written on line 1 of that file? If there is no line 1 or if line 1 is blank, enter Nothing.
b. What is written on line 2 of that file? If there is no line 2 or if line 2 is blank, enter Nothing.
c. What is written on line 3 of that file? If there is no line 3 or if line 3 is blank, enter Nothing.
d. What is written on line 4 of that file? If there is no line 4 or if line 4 is blank, enter Nothing.
e. What is written on line 5 of that file? If there is no line 5 or if line 5 is blank, enter Nothing.
Answer:
Joyner
David
USA
1.8
30
Explanation:
def saveUserProfile(firstName, lastName, age, height, country):
This is the definition of function named saveUserProfile which accepts the following parameters:
firstNamelastNameageheightcountryfilename = lastName + firstName + ".txt"
When the file is created it will be named as the lastName and firstName string combined with .txt as extension. For example if the lastName contains the name string Joyner and firstName contains the name David then the file created to be written is named as JoynerDavid.txt
outputFile = open(filename, "w")
This statement uses open() method in write mode and uses outputFile object to access the file. "w" represents write mode i.e. file is opened in write mode to write on it.
a) Joyner is written on line 1 of that file because of the following statement of above function:
print(lastName, file = outputFile)
This statement prints the string stored in lastName i.e. Joyner. Here outputFile opens the file in "w" write mode and writes the last name to the first line of the file.
b) David is written on line 2 of that file because of the following statement of above function:
print(firstName, file = outputFile)
This statement prints the string stored in firstName i.e. David. Here outputFile opens the file in "w" write mode and writes the first name to the second line of the file.
c) USA is written on line 3 of that file because of the following statement of above function:
print(country, file = outputFile)
This statement prints the data stored in country i.e. USA. Here outputFile opens the file in "w" write mode and writes the country name to the third line of the file.
d) 1.8 is written on line 4 of that file because of the following statement of above function:
print(height, file = outputFile)
This statement prints the value stored in height i.e. 1.8. Here outputFile opens the file in "w" write mode and writes the height value to the fourth line of the file.
e) 30 is written on line 5 of that file because of the following statement of above function:
print(age, file = outputFile)
This statement prints the value stored in age parameter of function saveUserProfile i.e. 30. Here outputFile opens the file in "w" write mode and writes the age value to the fifth line of the file.

3.16 (Gas Mileage) Drivers are concerned with the mileage obtained by their automobiles. One driver has kept track of several tankfuls of gasoline by recording miles driven and gallons used for each tankful. Develop a program that will input the miles driven and gallons used for each tankful. The program should calculate and display the miles per gallon obtained for each tankful. After processing all input information, the program should calculate and print the combined miles per gallon obtained for all tankfuls. Here is a sample input/output dialog:
Answer:
I am writing a C program.
#include <stdio.h> // for using input output functions
#include <stdbool.h> // for using a bool value as data type
int main() { // start of the main() function body
int count=0; //count the number of entries
double gallons, miles, MilesperGallon, combined_avg, sum; //declare variables
while(true) {// takes input gallons and miles value from user and computes avg miles per gallon
printf( "Enter the gallons used (-1 to stop): \n" ); //prompts user to enter value of gallons or enter -1 to stop
scanf( "%lf", &gallons );//reads the value of gallons from user
if ( gallons == -1 ) {// if user enters -1
combined_avg = sum / count; //displays the combined average by dividing total of miles per drives to no of entries
printf( "Combined miles per gallon for all tankfuls: %lf\n", combined_avg ); //displays overall average value
break;} //ends the loop
printf( "Enter the miles driven: \n" ); //if user does not enter -1 then prompts the user to enter value of miles
scanf( "%lf", &miles ); //read the value of miles from user
MilesperGallon = miles / gallons; //compute the miles per gallon
printf( "The miles per gallon for tankful: %lf\n", MilesperGallon ); //display the computed value of miles per gallon
sum += MilesperGallon; //adds all the computed miles per gallons values
count += 1; } } //counts number of tankfuls (input entries)
Explanation:
The program takes as input the miles driven and gallons used for each tankful. These values are stored in miles and gallons variables. The program calculates and displays the miles per gallon MilesperGallon obtained for each tankful by dividing the miles driven with the gallons used. The while loop continues to execute until the user enters -1. After user enters -1, the program calculates and prints the combined miles per gallon obtained for all tankful. At the computation of MilesperGallon for each tankful, the value of MilesperGallon are added and stored in sum variable. The count variable works as a counter which is incremented to 1 after each entry. For example if user enters values for miles and gallons and the program displays MilesperGallon then at the end of this iteration the value of count is incremented to 1. This value of incremented for each tankful and then these values are added. The program's output is attached.
Suppose that an engineer excitedly runs up to you and claims that they've implemented an algorithm that can sort n elements (e.g., numbers) in fewer than n steps. Give some thought as to why that's simply not possible and politely explain
Answer:
The summary including its given problem is outlined in the following section on the interpretation.
Explanation:
That's not entirely feasible, since at least n similarities have to be made to order n quantities. Find the finest representation where the numbers of 1 to 10 have already been arranged.
⇒ 1 2 3 4 5 6 7 8 9 10
Let's say that we identify one figure as the key then compared it towards the numbers across the left. Whether the correct number is greater, therefore, left number, are doing nothing to switch the location elsewhere.
Because although the numbers have already been categorized 2 has always been compared to 1 which would be perfect, 3 becomes especially in comparison to 2 and so much more. This should essentially take 9 moves, or nearly O(n) moves.
If we switch that little bit already
⇒ 1 3 2 4 5 6 7 8 9 10
3 Is contrasted with 1. 2 will indeed be matched against 3 as well as 2. Since 2 has indeed been exchanged, it must, therefore, be matched with 1 as there might be a case whereby each number z exchanged is greater than the number Y as well as the quantity X < Y.
X = 1, Y = 3, and Z = 2.Only one adjustment expanded the steps which culminated in n+1.
It should be noted that it won't be possible because at least n similarities have to be made to order n quantities.
From the information given, it should be noted that it's not possible for the engineer to implement an algorithm that can sort n elements (e.g., numbers) in fewer than n steps.
This is because there are at least n similarities have to be made to order n quantities. In this case, the numbers of 1 to 10 have already been arranged. When a number is greater, it should be noted that the left number will do nothing to switch the location elsewhere.
Therefore, the information given by the engineer isn't feasible.

A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the right.
For example, we can shift the bits in the string 1011 two places to the left to produce the string 1110. Note that the leftmost two bits are wrapped around to the right side of the string in this operation.
Define two scripts, shiftLeft.py and shiftRight.py, that expect a bit string as an input.
The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the rightmost position.
The script shiftRight performs the inverse operation.
Each script prints the resulting string.
An example of shiftLeft.py input and output is shown below:
Enter a string of bits: Hello world!
ello world!H
An example of shiftRight.py input and output is shown below:
Enter a string of bits: Hello world!
!Hello world
Answer:
Following are the code to this question:
Defining method shiftLeft:
def shiftLeft(bit_string): #defining method shiftLeft, that accepts parameter bit_string
bit_string= bit_string[1:]+bit_string[0]#use bit_string to provide slicing
return bit_string#return bit_string value
bit_string =input("Enter value: ")#defining bit_string variable for user input
print (shiftLeft(bit_string))#use print method to call shiftLeft method
Defining method shiftRight:
def shiftRight(bit_string):#defining method shiftRight, which accepts bit_string variable
bit_string=bit_string[len(bit_string)-1]+bit_string[0:len(bit_string)-1]#using bit_string variable for slicing
return bit_string#return bit_string calculated value
bit_string= input("Enter value: ")#defining bit_string variable for user input
print(shiftRight(bit_string))#use print method to call shiftLeft method
Output:

Answer:
The answer is "For the stop and wait the value of S and R is equal to 1".
Explanation:
As we know that, the SR protocol is also known as the automatic repeat request (ARQ), this process allows the sender to sends a series of frames with window size, without waiting for the particular ACK of the recipient including with Go-Back-N ARQ. This process is mainly used in the data link layer, which uses the sliding window method for the reliable provisioning of data frames, that's why for the SR protocol the value of S =R and S> 1.What is the main advantage of using DHCP?

Which of the following is not true? A These describe the authority level of workers, fair payment practices, communication channels, and the like. B This describes organizational governance framework. C This describes management elements. D This is part of the EEF input to this process.
Answer:
A. These describe the authority level of workers, fair payment practices, communication channels, and the like.
Explanation:
As seen in the question above, you have been asked to write the project management plan and know that you need to consider elements such as policies, rules, systems, relationships and standards in the organization. These elements are part of EEF's entry into this process, in addition they are fundamental and indispensable for the description not only of the organizational governance structure, but also describe the management elements that will be adopted and used.
However, there is no way to use them to describe the level of authority of workers, fair payment practices, communication channels and the like, as this is not the function of this.

A security administrator is investigating a report that a user is receiving suspicious emails. The user's machine has an old functioning modem installed. Which of the following security concerns need to be identified and mitigated? (Select TWO).
a) Vishing
b) Whaling
c) Spear phishing
d) Pharming
e) War dialing
f) Hoaxing
Answer:
Spear Phishing and War Dialing
Explanation:
So let's tackle these one at a time.
Vishing is simply any type of message (i.e., email, text, phone call, etc.) that appears to be from a trusted source but is not.
Whaling is simply a spear phishing attack of a high-value target such as a CEO or someone with high-level access at a company.
Spear phishing is simply a targeted phishing attack, usually towards a specific person or group of people. (Phishing attack is simply a social attack to try and gain unauthorized access to a resource).
Pharming is an attack that attempts to redirect website traffic to a fake site.
War dialing is a technique to automatically scan a list of numbers in an area in attempt to search for exposed modems, computers, board systems, or fax machines, in order to breach the network.
Hoaxing is simply a social attack that describes a serious threat in attempts to retrieve unauthorized access or money from a victim. (Think microsoft tech support scams)
Now that we have defined these things, let's identify the possible threats that need to be reported.
(a) Vishing? The sec admin report doesn't mention the source of the message so we cannot associate this one
(b) Whaling? The sec admin report says a user, implying someone not high up in the company, but doesn't say it's not someone high up. This is possible.
(c) Spear phishing? The sec admin report says a user, implying that only this user is being targeted so this is definitely valid.
(d) Pharming? The sec admin report says nothing about site redirection.
(e) War dialing? The sec admin report doesn't say anything about unauthorized scanning; however, it mentions the user has an old functioning modem, so this is possible.
(f) Hoaxing? The sec admin report doesn't mention a pop up in the email or the content of the email so we are uncertain.
Thus with these considerations, the two threats that are identified and need mitigation are Spear phishing and War Dialing/Whaling. Note that we aren't positive of the war dialing or whaling, but a case could be made for either; however, given the modem information, the question seems to indicate war dialing.

#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
double side, height;
cout<<"Enter the length of one of the sides of the base: ";
cin>>side;
cout<<"Enter the height: ";
cin>>height;
double area = side * side;
double volume = area * height / 3;
cout<<"The area of the base of the pyramid is: "<<area<<endl;
cout<<"The height of the pyramid is: "<<height<<endl;
cout<<"The volume of the pyramid is: "<<fixed<<setprecision(2)<<volume<<endl;
return 0;
}
Pseudocode:
Declare side, height
Get side
Get height
Set area = side * side
Set volume = area * height / 3
Print area
Print height
Print volume
Explanation:
Include <iomanip> to have two decimal places
Declare the side and height
Ask the user to enter side and height
Calculate the base area, multiply side by side
Calculate the volume using the given formula
Print area, height and volume (use fixed and setprecision(2) to have two decimal places)

Write a method named removeDuplicates that accepts a string parameter and returns a new string with all consecutive occurrences of the same character in the string replaced by a single occurrence of that character. For example, the call of removeDuplicates("bookkeeeeeper") should return "bokeper" .
Answer:
//Method definition
//Method receives a String argument and returns a String value
public static String removeDuplicates(String str){
//Create a new string to hold the unique characters
String newString = "";
//Create a loop to cycle through each of the characters in the
//original string.
for(int i=0; i<str.length(); i++){
// For each of the cycles, using the indexOf() method,
// check if the character at that position
// already exists in the new string.
if(newString.indexOf(str.charAt(i)) == -1){
//if it does not exist, add it to the new string
newString += str.charAt(i);
} //End of if statement
} //End of for statement
return newString; // return the new string
} //End of method definition
Sample Output:
removeDuplicates("bookkeeeeeper") => "bokeper"
Explanation:
The above code has been written in Java. It contains comments explaining every line of the code. Please go through the comments.
The actual lines of codes are written in bold-face to distinguish them from comments. The program has been re-written without comments as follows:
public static String removeDuplicates(String str){
String newString = "";
for(int i=0; i<str.length(); i++){
if(newString.indexOf(str.charAt(i)) == -1){
newString += str.charAt(i);
}
}
return newString;
}
From the sample output, when tested in a main application, a call to removeDuplicates("bookkeeeeeper") would return "bokeper"
