Answer:
Port scanner
Explanation:
The penetration tester would most likely use a port scanner. A port scanner can be explained to be an application that is made to check a server or host for ports that are open. This application can also be used by administrators to check their security networks so as to know those network services that are running on a host and also to know existing vulnerabilities. Attackers also use this to exploit victims.

Cryptocurrencies are digital tokens that are created independently of government money, and can act as a medium of exchange and store of value. Which other instrument could most reasonably fulfill the same function
Answer:
Gold
Explanation:
From the question, we are informed about Cryptocurrencies which are digital tokens that are created independently of government money, and can act as a medium of exchange and store of value. One of other instrument that could most reasonably fulfill the same function is Gold. A medium of exchange can be regarded as a intermediary instrument which is a function of money that facilitate trade or purchase and selling between seller and buyers, and it must be accepted as payment for transactions. Such intermediary instrument as a medium of exchange are Gold, salt as well as stone. Gold was chosen by most of the commodity-money advocates as a medium of exchange as a result of the intrinsic property it posses, and it's fixed stock value
Write a program that declares an array named myArray with 8 components of the type int. Initialize the array to 8 values that the user inputs (remember to prompt the user). Finally, pass the array as a parameter to a new function called filterEvens. This new function will display all of the even numbers in the array.
Answer:
#include <iostream>
using namespace std;
void filterEvens(int myArray[]) {
for (int i = 0; i < 8; ++i) {
if(myArray[i]%2==0){
cout<<myArray[i]<<" ";
}
}
}
int main(){
int myArray[8];
for(int i =0;i<8;i++){
cin>>myArray[i];
}
filterEvens(myArray);
return 0;
}
Explanation:
The solution is provided in C++
#include <iostream>
using namespace std;
The function filerEvens is defined here
void filterEvens(int myArray[]) {
This iterates through the elements of the array
for (int i = 0; i < 8; ++i) {
This checks if current element is an even number
if(myArray[i]%2==0){
If yes, this prints the array element
cout<<myArray[i]<<" ";
}
}
}
The main begins here
int main(){
This declares an integer array of 8 elements
int myArray[8];
The following iteration allows input into the array
for(int i =0;i<8;i++){
cin>>myArray[i];
}
This calls the defined function filter Evens
filterEvens(myArray);
return 0;
}

Write a function max_magnitude() with two integer input parameters that returns the largest magnitude value. Use the function in a program that takes two integer inputs, and outputs the largest magnitude value. Ex: If the inputs are: 5 7 the function returns: 7 Ex: If the inputs are: -8 -2 the function returns: -8 Note: The function does not just return the largest value, which for -8 -2 would be -2. Though not necessary, you may use the built-in absolute value function to determine the max magnitude, but you must still output the input number (Ex: Output -8, not 8). Your program must define and call the following function:
Answer:
The question is answered in python
def max_magnitude(a,b):
if abs(a) > abs(b):
return a
else:
return b
num1 = int(input("Num 1: "))
num2 = int(input("Num 2: "))
print(max_magnitude(num1,num2))
Explanation:
This question is answered using the concept of absolute value to get the integer with the highest magnitude
First, the function is defined with integer parameters a and b
def max_magnitude(a,b):
This checks if a has the highest magnitude
if abs(a) > abs(b):
If true, it returns a
return a
If otherwise, it returns b
else:
return b
The main starts here
The next two lines prompt the user for inputs
num1 = int(input("Num 1: "))
num2 = int(input("Num 2: "))
This calls the function
print(max_magnitude(num1,num2))
What are some of the ways we can resolve IPv4 address shortages? Check all that apply.
Answer:
I am not as close to the network as I used to be but I have not seen articles about the network apocalypse due to IPv4 address depletion. Unlike in the late 90’s when predictions of apocalypse were everywhere.
What happened?
Two things:
Network address translation (NAT) was introduced to allow organizations to use private addresses on their internal network and minimize the requirement for “real” IP4 addresses.
Second, IPv6 was created and introduced to expand the number of addresses available.
So, a direct answer is use IPv6 and/or NAT for internal networks.
Explanation:
A Web server has five major components that must all function in order for it to operate as intended. Assuming that each component of the system has the same reliability and one of the components will have a backup with a reliability equal to that of any one of the other components, what is the minimum reliability each one must have in order for the overall system to have a reliability of 0.696
Answer:
The answer is below
Explanation:
Let x represent the reliability of each of the five major components. Since all the components must function before the system operates, hence they are in series with each other.
One component has a backup of the same reliability, the reliability of the back up system = 1 - (1 - x)² = 2x - x²
Therefore the reliability of the system is:
x * x * x * x * (2x - x²) = 0.696
2x⁵ - x⁶ = 0.696
x⁶ - 2x⁵ + 0.696 = 0
Solving the polynomial equation online using byjus.com gives:
x = 0.915038
x = 1.97695
x = -0.632585 - 0.429075 i
x = -0.632585 + 0.429075 i
x = 0.186590 - 0.789741 i
x = 0.186590 + 0.789741 i
Since the reliability is not a complex number and it is less than or equal to 1, hence:
x = 0.915038, x ≅ 0.915
In the program below, which variable has the same scope as strA?
def usernameMaker (strFirst, strLast):
return strFirst + strLast[0]
def passwordMaker (strA, numC):
if len(strA) > 4:
answer = dogName[0:3]
return answer + str(numC)
else:
return 'xk&' + str(numC)
Answer:
" numC " is the correct answer
Explanation:
The reason is that on line 3 of code it has "def passwordMaker (strA, numC):"
strA and numC are both in "( )" which is the scope and only things inside are varibles. Also its the only line that has strA in it.
The scope of a variable is the extent at which the variable can be referenced.
The variable with the same scope as strA is variable numC
From the program, we have the following function definition
def passwordMaker (strA, numC):
Variables strA and numC are declared along with the function passwordMaker
This means that:
Variables strA and numC have the same scope
Hence, the variable with the same scope as strA is variable numC

Assume you have the all_info list that is given in the Do It Now problem 1. This list includes the grades of 4 courses for 4 students. Write a code that asks a name from the user. Then it will search for that name in the list all info. Of the name exists in the list, the program will display the programming grade of that student. For example, if the user enters 'Sarah ' the program will display 90. If the user enters a name that is not in the list, such as 'Jack', the program will display an error message such as 'Sorry, but this student is not in the list'.
Answer:
titles =['name', 'physics', 'chemistry', 'math', 'programming']
student_1 =['Kathy', 90, 80, 75, 100]
student_2 =['John', 65, 84, 79, 90]
student_3 =['Joe', 45, 89, 100, 10]
student_4 =['Sarah', 68, 89, 93, 90]
all_info =[titles, student_1, student_2, student_3, student_4]
student = input("Enter student's name: ")
student_list = [name[0] for name in all_info]
if student in student_list:
print(all_info[student_list.index(student)][4])
if student not in student_list:
print("Student name does not exist.")
Explanation:
The python program prompts for user input "student" and the input is used to search and return the result of the student in the programming exam. If the name is not in the student_list, the program print an error message.
Implement a program called genes.py that does the following: a. Reads a DNA sequence t as command-line argument b. Reads strings (one by one) representing genes from standard input until EOF (use the functions stdio.isEmpty() and stdio.readString()), and for each string s i. Constructs a Gene object g from s ii. Writes g iii. Writes whether g contains the DNA sequence t or not c. Writes the percentage of genes that contain t, up to two decimal places
Answer:
Following are the code to this question:
import sys#import package sys
class Gene:#defining a class Gene
gString = ""#defining a string variable
def __init__(self, gString):#defining a constructor
self.gString = gString#defining object to hold string value
gCount = 0#defining integer variable
mCount = 0#defining integer variable
t = input();#input value from user end
for s in sys.stdin:#defining for loop to check input value
g = Gene(s)#defining g variable to pass value in class parameter
gCount +=1#incrementing the value of gCount variable
if(t in s):#defining if block to check input
mCount +=1#incrementing the matchCount value
print( g.gString,"True")#print value True
else:#else block
print( g.gString,"False")#print value False
print("{:.2f}".format(mCount*100/gCount))#print percentage value
Output:
Please find attachment file.
Explanation:
In the code, a class Gene is declared, that defines a string variable geneString, and creates its constructor, and store the string variable value.
In the next step, a three-variable gCount, mCount, and t defined, in which variable "t" is used for an input value, and inside the for loop, it uses the conditional statement, that checks its value and increments the integer value, and print true or false as a message.
What are the correct steps to add the bill using the receipt capture feature in quick books online?
Answer:
How it Works
The Bill can be imported into QuickBooks in a verity of methods such as drag and drop, browse to upload, email and image upload from a mobile device. The imported data is processed by QuickBooks. In my testing this processing varied depending on the type of document sent but overall, the process was fast, and the Bill was ready to view and categorized within five minutes. There were several pieces of data already extracted from the document which were the data and dollar amount but all other details in my experience needed to be entered.
One thing to not is you can not expense by line items at this time. Instead you can only choose one expenses account per transaction. (if I were a betting girl, I would say this is in the works, but I have no official word on that) However, you can add Classes and Billable Customers.
How to Get Started:
1) From the QBO Navigation Bar choose Banking Center
2) Select the Receipts tab
3) Drag and drop, email or upload a mobile image of the document to QuickBooks (1 file at a time)
4) From the For Review section of the Receipts tab you can see when the document is ready for review
5) QuickBooks extracts, data including date and dollar amount
6) Click on Review in the Action column
7) Select Bill as Document Type (as shown highlighted in the 'red box')
8) Enter the remaining details:
- Enter Payee
- Approve Bill date and enter due date
- Select Account
- Verify amount total
- Additional Fields (optional)
- Make expenses billable
- Select Customer
- Class
- Add reference number
9) Import into QuickBooks by Saving and Closing
Within, seconds your document is coded and published into QuickBooks as an Open Bill pending payment. Like I said for now all you can add is an account but if you published the document to QBO you could later open it and edit to add required items if necessary.
The last step in optimization is after you have posted the payment to the open bill you will be able to match the bank feeds in QBO if you have already imported your banking activity. This type of audit proofing your bookkeeping helps prevent fraud and assures accuracy.

everything?
Separation of duties
Responsibility sharing
Separation of responsibility
None
Answer:
If the responsibilities are distributed ,the disputes amongst people wont take place because their wont be any partiality, everyone would be equal. Moreover it is difficult for one person to control everything at once and multiple people would help the work to be organized as everyone will have their own part of work which is supposed to be fulfilled.
4. In a relational database, entities are defined by
O A. values.
O B. columns.
O C. attributes.
O D. rows.
Answer:
C. attributes
Explanation:
A relational database is a database system that stores information within its servers. It has rows and columns that contain the data stored in them and which can be accessed at any time with the right administrative privileges.
In a relational database, entities are defined by their attributes. This is because an entity is the data that needs to be stored so, the attribute specifies that information and gives its value.
Write a class called Date that represents a date consisting of a day, month, and year. A date object should have the following methods: public Date(int day, int month, int year) -- Constructs a new Date object to represent the given date public int getDay() -- returns the day value of this date public int getMonth() -- returns the month value of this date public int getYear() -- returns the year value of this date public void addDays(int days) -- Moves the Date object forward in time by the given number of days public int daysTo(Date other) -- Returns the number of days between this Date and the other Date public boolean isLeapYear() -- Returns true if the year of this Date is a leap year. A leap year occurs when the value of the year is divisible by 4, except when it is divisible by 100 and not 400 (so 1700, 1800, and 1900 are not leap years) public String toString() -- returns a String representation of this date in the form day/month/year Write a program in which to test your class. This program should prompt the user to enter the days, months, and years of two separate dates, and then print out the number of days between these two dates.

The key operation in encryption and decryption process is the exponentstion. Given an integer x it is easy to write a linear algo O((n)) to find x^n for any integer n. Describe the maths of a fast exponentation algo that can compute x^n in o(log2n) time. Justify
Answer:
Following are the solution to this question:
Explanation:
[tex]x^n[/tex] could be approximated by getting a small n loop as well as multiplying x for each incarnation in a linear time. It's very simple. Its key concept is to do it in log2n time.
[tex]x^n = x^{\frac{n}{2}}\ is \ obvious \ \ x^{\frac{n}{2}}[/tex]
Therefore,[tex]x^{n}, x^{\frac{n}{2}}[/tex] could be determined and divided by itself instead of [tex]x^n[/tex] calculation. It must be done frequently to ensure which half the research is done out with each stage.
Runtime:
Its repetition relationship of the above function is:
[tex]T(n) = T(\frac{n}{2}) + 1[/tex]
This can be resolved by master theorem, so it's obvious. The running time of this repeating ration, by master theorem, is [tex]O ( \log_2n )[/tex].
Pseudocode:
int exponent( int x_1, int y_1 )//defining a method exponent
{
if(y_1==1) //use if to check n value equal to 1
{return x_1;} //return x value
Int t= exponent(x_1,y_1/2);//call method
return t*t;//calculate square
