Explain why it is not necessary to create an inbound rule on the internal 192.168.12.10 Windows server so that it can receive the response (ICMP echo reply) from the internal 192.168.12.11 Windows server.
Answer:
The file and printer sharing (Echo Request - ICMPv4-In) rule option should be listed for all profile.
Explanation:
The main reason why it is not compulsory or obligatory to design an inbound rule on the internal 192.168.12.10 Windows server in other to be able to accept the response (ICMP echo reply) generated from the internal 192.168.12.11 Windows server is that the file and printer sharing (Echo Request - ICMPv4-In) rule option or alternative needed to be listed for all profile.
Inbound rules filter or sieve traffic advancing from the network to the local computer based on the filtering conditions set out in the rule.
You are a project manager for Laredo Pioneer's Traveling Rodeo Show. You're heading up a project to promote a new line of souvenirs to be sold at the shows. You are getting ready to write the project management plan and know you need to consider elements such as policies, rules, systems, relationships, and norms in the organization. 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.
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. 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.
Write an application that calculates and displays the amount of money a user would have if his or her money could be invested at 5 percent interest for one year. Create a method that prompts the user for the starting value of the investment and returns it to the calling program. Call a separate method to do the calculation, and return the result to be displayed. Save the program as Interest.java.
Answer:
Following are the program to this question:
import java.util.*;//import package for user input
class Interest //defining class Interest
{
static double rate_of_interest = 5.00;//defining static double varaibale
public static double Invest_value()//defining method Invest_value
{
double invest;//defining double variable invest
Scanner inc = new Scanner(System.in);//creating Scanner class object
System.out.print("Enter investment value: ");
invest = inc.nextDouble();//input value in invest variable
return invest;//return invest value
}
public static double calculated_Amount(double invest)//defining method calculated_Amount that accept parameter
{
double amount;//defining double variable
amount = invest+ (invest * (rate_of_interest/100));//use amount to calculat 5 % of invest value
return amount;//return amount value
}
public static void main(String[] as)//defining main method
{
double investment_value;//defining double variable
investment_value= Invest_value();//use investment_value to hold method Invest_value value
System.out.println("The 5% of the invest value: "+ calculated_Amount(investment_value));//use print method to print calculated_Amount value
}
}
Output:
Enter investment value: 3000
The 5% of the invest value: 3150.0
Explanation:
In the above program a class "Interest", is defined inside the class a static double variable "rate_of_interest" is declared that store a double value, in the next step, two methods "Invest_value and calculated_Amount" is declared.
In the "Invest_value" method, scanner class object is created for input value in the "invest" variable and the "calculated_Amount" accepts an "invest" value in its parameter and calculate its 5% and store its value in the "amount" variable.
Inside the main method, the "investment_value" is declared that holds the "Invest_value" method value and pass the value in the "investment_value" variable in the "calculated_Amount" method and prints its return value.
What will be displayed if code corresponding to the following pseudocode is executed? Set Number = 4 Repeat Write 2 * Number Set Number = Number + 2 Until Number = 8
Answer:
8
12
Explanation:
I made the code a bit easier to understand then worked out how it would go. Here's what I did.
number = 4
repeat until number = 8:
write 2 * number
number = number + 2
Following this itenary, we have, the system first writes "8" as it multipled 4 by 2. Number is now equal to 6.
Next repetition, the system writes "12" as it multipled 6 by 2. Now, number = 8. The proccess now stops as number is now equal to 8.

The compare_strings function is supposed to compare just the alphanumeric content of two strings, ignoring upper vs lower case and punctuation. But something is not working. Fill in the code to try to find the problems, then fix the problems.
import re
def compare_strings(string1, string2):
#Convert both strings to lowercase
#and remove leading and trailing blanks
string1 = string1.lower().strip()
string2 = string2.lower().strip()
#Ignore punctuation
punctuation = r"[.?!,;:-']"
string1 = re.sub(punctuation, r"", string1)
string2 = re.sub(punctuation, r"", string2)
#DEBUG CODE GOES HERE
print(___)
return string1 == string2
print(compare_strings("Have a Great Day!", "Have a great day?")) # True
print(compare_strings("It's raining again.", "its raining, again")) # True
print(compare_strings("Learn to count: 1, 2, 3.", "Learn to count: one, two, three.")) # False
print(compare_strings("They found some body.", "They found somebody.")) # False
Answer:
There is a problem in the given code in the following statement:
Problem:
punctuation = r"[.?!,;:-']"
This produces the following error:
Error:
bad character range
Fix:
The hyphen - should be placed at the start or end of punctuation characters. Here the role of hyphen is to determine the range of characters. Another way is to escape the hyphen - using using backslash \ symbol.
So the above statement becomes:
punctuation = r"[-.?!,;:']"
You can also do this:
punctuation = r"[.?!,;:'-]"
You can also change this statement as:
punctuation = r"[.?!,;:\-']"
Explanation:
The complete program is as follows. I have added a print statement print('string1:',string1,'\nstring2:',string2) that prints the string1 and string2 followed by return string1 == string2 which either returns true or false. However you can omit this print('string1:',string1,'\nstring2:',string2) statement and the output will just display either true or false
import re #to use regular expressions
def compare_strings(string1, string2): #function compare_strings that takes two strings as argument and compares them
string1 = string1.lower().strip() # converts the string1 characters to lowercase using lower() method and removes trailing blanks
string2 = string2.lower().strip() # converts the string1 characters to lowercase using lower() method and removes trailing blanks
punctuation = r"[-.?!,;:']" #regular expression for punctuation characters
string1 = re.sub(punctuation, r"", string1) # specifies RE pattern i.e. punctuation in the 1st argument, new string r in 2nd argument, and a string to be handle i.e. string1 in the 3rd argument
string2 = re.sub(punctuation, r"", string2) # same as above statement but works on string2 as 3rd argument
print('string1:',string1,'\nstring2:',string2) #prints both the strings separated with a new line
return string1 == string2 # compares strings and returns true if they matched else false
#function calls to test the working of the above function compare_strings
print(compare_strings("Have a Great Day!","Have a great day?")) # True
print(compare_strings("It's raining again.","its raining, again")) # True
print(compare_strings("Learn to count: 1, 2, 3.","Learn to count: one, two, three.")) # False
print(compare_strings("They found some body.","They found somebody.")) # False
The screenshot of the program along with its output is attached.
Following are the modified program to the given question:
Program Explanation:
Import package.Defining a method "compare_strings" that takes two parameters "string1, string2".Inside the method, parameter variables have been used that convert and hold string values into lower case.In the next step, a variable "punctuation" is defined that holds value.After this, a parameter variable is used that calls the sub-method that checks parameter value with punctuation variable value, and at the return keyword is used that check string1 value equal to string2.Outside the method, multiple print method is used calls the method, and prints its value.Program:

A printer is connected locally on Computer1 and is shared on the network. Computer2 installs the shared printer and connects to it. Computer1 considers the printer to be a(n) ________________ printer, and Computer2 considers the printer to be a(n) ________________ printer.
Answer:
A printer is connected locally on Computer1 and is shared on the network. Computer2 installs the shared printer and connects to it. Computer1 considers the printer to be a(n) _____local___________ printer, and Computer2 considers the printer to be a(n) _____network___________ printer.
Explanation:
Any printer installed directly to Computer 1 is a local printer. If this printer is then shared with computers 2 and 3 in a particular networked environment, it becomes a shared printer. For these other computers 2 and 3, the shared printer is a network printer, because it is not locally installed in each of them. There may be some features which network computers cannot use on a shared printer, especially if the printer can scan documents.
The conversion of symbolic op codes such as LOAD, ADD, and SUBTRACT to binary makes use of a structure called the ____.
Answer:
Op code table.
Explanation:
In Computer programming, an Op code is the short term for operational code and it is the single instruction which can be executed by the central processing unit (CPU) of a computer.
The conversion of symbolic op codes such as LOAD, ADD, and SUBTRACT to binary makes use of a structure called the Op code table. The Op code can be defined as a visual representation of the entire operational codes contained in a set of executable instructions.
An Op code table is arranged in rows and columns which basically represents an upper or lower nibble and when combined depicts the full byte of the operational code. Each cells in the Op code table are labeled from 0-F for the rows and columns; when combined it forms values ranging from 00-FF which contains information about CPU cycle counts and instruction code parameters.
Hence, if the operational code table is created and sorted alphabetically, the binary search algorithm can be used to find an operational code to be executed by the central processing unit (CPU).
A systems administrator wants to replace the process of using a CRL to verify certificate validity. Frequent downloads are becoming problematic. Which of the following would BEST suit the administrators needs?
A. OCSP
B. CSR
C. Key escrow
D. CA
Answer:
A. OCSP
Explanation:
Online Certificate Status Protocol (OCSP) is an Internet Protocol that is used as an alternative for CRL and is used to obtain the revocation status of a digital certificate.
A certificate revocation list (CRL) is a set of digital certificates that have been rendered invalid/revoked by the Certificate Authority (CA) because they can no longer be trusted.
Because an OCSP response uses less data than a CRL, it would be best suited to the administrator's needs.

Use ____ references when you want different formulas to refer to the same cell.
Answer:
absolute
Explanation:
Use absolute references when you want different formulas to refer to the same cell.
What are absolute references?When dragging rows and columns to replicate formulas in Microsoft Excel, absolute references are the cell references you wish to maintain constant. For instance, the value in cell J4 is necessary for each and every cell in column K.
The reference would go from J4 to J5, then J6, and so on if you dragged it along column K. References that are absolute don't alter when copied or filled. To maintain the consistency of a row and/or column, utilize an absolute reference.
By including a dollar sign, a formula designates an absolute reference. The column reference, the row reference, or both may come before it.
Therefore, when you want different formulas to refer to the same cell, use absolute references.

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"
We will pass in a value N. Write a program that outputs the complete Fibonacci sequence for N iterations. Important: If N is 0, then we expect to get an output of 0. If N=1 then we expect 0, 1 etc.
Answer:
The program written in Python is as follows
def fibonac(N):
series = ""
for i in range(0,N+1):
series = series + str(i) + ","
return series[:-1]
N = int(input("Number: "))
print(fibonac(N))
Explanation:
This line defines the function fibonac
def fibonac(N):
This line initializes variable "series" to an empty string
series = ""
This line iterates through the passed argument, N
for i in range(0,N+1):
This line determines the Fibonacci sequence
series = series + str(i) + ","
Lastly, this line returns the Fibonacci sequence
return series[:-1]
The main starts here
The firs line prompts user for input
N = int(input("Number: "))
This line prints the Fibonacci sequence
print(fibonac(N))

What is industry 4.0 -automation revolution-, what is your opinion about the direction this revolution is taking the industry in, and discuss the fate of unskilled and semi-skilled workers affected by industry 4.0.
Answer:
Find the explanation below.
Explanation:
1. Industry 4.0 -automation revolution is a term first used in Germany in 2011 to describe the fourth generation of the industrial revolution. It is the incorporation of digitalized procedures that use smart technology that can work in real-time to industrial production. This means that the machines used in production can independently interact between themselves to accomplish tasks that would otherwise have needed human involvement.
2. My opinion regarding this industrial revolution is that it is a welcome development for businesses because it will help them execute projects at faster rates and limit some working expenses.
3. Unskilled and Semi-skilled workers will be badly affected by this revolution because tasks ordinarily performed by them would be mostly taken over by these machines. This means that companies would most likely lay off these workers whose jobs would now be performed by machines. Job regulation agencies would do well to seek ways to intervene for this group of workers. They may also have to improve their skills if they want to remain relevant to their jobs.
The revolution, however, would be favorable for high-skilled workers because they would be needed to perform jobs such as the maintenance and programming of these machines.

using namespace std;
class Song {
public:
void SetNameAndDuration(string songName, int songDuration) {
name = songName;
duration = songDuration;
}
void PrintSong() const {
cout << name << " - " << duration << endl;
}
string GetName() const { return name; }
int GetDuration() const { return duration; }
private:
string name;
int duration;
};
class Album {
public:
void SetName(string albumName) { name = albumName; }
void InputSongs();
void PrintName() const { cout << name << endl; }
void PrintSongsShorterThan(int songDuration) const;

vector albumSongs;
};
void Album::InputSongs() {
Song currSong;
string currName;
int currDuration;
cin >> currName;
while (currName != "quit") {
cin >> currDuration;
currSong.SetNameAndDuration(currName, currDuration);
albumSongs.push_back(currSong);
cin >> currName;
}
}
void Album::PrintSongsShorterThan(int songDuration) const {
unsigned int i;
Song currSong;
cout << "Songs shorter than " << songDuration << " seconds:" << endl;
/* Your code goes here */
}
int main() {
Album musicAlbum;
string albumName;
getline(cin, albumName);
musicAlbum.SetName(albumName);
musicAlbum.InputSongs();
musicAlbum.PrintName();
musicAlbum.PrintSongsShorterThan(210);
return 0;
}
Answer:
Here is the function PrintSongsShorterThan() which prints all the songs from the album shorter than the value of the parameter songDuration.
void Album::PrintSongsShorterThan(int songDuration) const {
unsigned int i;
Song currSong;
cout << "Songs shorter than " << songDuration << " seconds:" << endl;
for(int i=0; i<albumSongs.size(); i++){
currSong = albumSongs.at(i);
if(currSong.GetDuration()<songDuration){
currSong.PrintSong(); } } }
Explanation:
I will explain the working of the for loop in the above function.
The loop has a variable i that is initialized to 0. The loop continues to execute until the value of i exceeds the albumSongs vector size. The albumSongs is a Song type vector and vector works just like a dynamic array to store sequences.
At each iteration the for loop checks if the value of i is less than the size of albumSongs. If it is true then the statement inside the loop body execute. The at() is a vector function that is used to return a reference to the element at i-th position in the albumSongs. So the album song at the i-th index of albumSongs is assigned to the currSong. This currSong works as an instance. Next the if condition checks if that album song's duration is less than the specified value of songDuration. Here the method GetDuration() is used to return the value of duration of the song. If this condition evaluates to true then the printSong method is called using currSong object. The printSong() method has a statement cout << name << " - " << duration << endl; which prints/displays the name of the song with its duration.
If you see the main() function statement: musicAlbum.PrintSongsShorterThan(210);
The musicAlbum is the Album object to access the PrintSongsShorterThan(210) The value passed to this method is 210 which means this is the value of the songDuration.
As we know that the parameter of PrintSongsShorterThan method is songDuration. So the duration of each song in albumSongs vector is checked by this function and if the song duration is less than 210 then the name of the song along with its duration is displayed on the output screen.
For example if the album name is Anonymous and the songs name along with their duration are:
ABC 400
XYZ 123
CDE 300
GHI 200
KLM 100
Then the above program displays the following output when the user types "quit" after entering the above information.
Anonymous
Songs shorter than 210 seconds:
XYZ - 123
GHI - 200
KLM - 100
Notice that the song name ABC and CDE are not displayed because they exceed the songDuration i.e. 210.
The output is attached.

Explanation:
Start with the following Python code. alphabet = "abcdefghijklmnopqrstuvwxyz" test_dups = ["zzz","dog","bookkeeper","subdermatoglyphic","subdermatoglyphics"] test_miss = ["zzz","subdermatoglyphic","the quick brown fox jumps over the lazy dog"] # From Section 11.2 of: # Downey, A. (2015). Think Python: How to think like a computer scientist. Needham, Massachusetts: Green Tree Press. def histogram(s): d = dict() for c in s: if c not in d: d[c] = 1 else: d[c] += 1 return d Copy the code above into your program but write all the other code for this assignment yourself. Do not copy any code from another source. Part 1 Write a function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters. Otherwise, it should return False. Implement has_duplicates by creating a histogram using the histogram function above. Do not use any of the implementations of has_duplicates that are given in your textbook. Instead, your implementation should use the counts in the histogram to decide if there are any duplicates. Write a loop over the strings in the provided test_dups list. Print each string in the list and whether or not it has any duplicates based on the return value of has_duplicates for that string. For example, the output for "aaa" and "abc" would be the following. aaa has duplicates abc has no duplicates Print a line like one of the above for each of the strings in test_dups. Part 2 Write a function called missing_letters that takes a string parameter and returns a new string with all the letters of the alphabet that are not in the argument string. The letters in the returned string should be in alphabetical order. Your implementation should use a histogram from the histogram function. It should also use the global variable alphabet. It should use this global variable directly, not through an argument or a local copy. It should loop over the letters in alphabet to determine which are missing from the input parameter. The function missing_letters should combine the list of missing letters into a string and return that string. Write a loop over the strings in list test_miss and call missing_letters with each string. Print a line for each string listing the missing letters. For example, for the string "aaa", the output should be the following. aaa is missing letters bcdefghijklmnopqrstuvwxyz If the string has all the letters in alphabet, the output should say it uses all the letters. For example, the output for the string alphabet itself would be the following. abcdefghijklmnopqrstuvwxyz uses all the letters Print a line like one of the above for each of the strings in test_miss. Submit your Python program. It should include the following. The provided code for alphabet, test_dups, test_miss, and histogram. Your implementation of the has_duplicates function. A loop that outputs duplicate information for each string in test_dups. Your implementation of the missing_letters function. A loop that outputs missing letters for each string in test_miss. Also submit the output from running your program. Your submission will be assessed using the following Aspects. Does the program include a function called has_duplicates that takes a string parameter and returns a boolean? Does the has_duplicates function call the histogram function? Does the program include a loop over the strings in test_dups that calls has_duplicate on each string? Does the program correctly identify whether each string in test_dups has duplicates? Does the program include a function called missing_letters that takes a string parameter and returns a string parameter? Does the missing_letters function call the histogram function? Does the missing_letters function use the alphabet global variable directly? Does the program include a loop over the strings in test_miss that calls missing_letters on each string? Does the program correctly identify the missing letters for each string in test_miss, including each string that "uses all the letters"?
Answer:
alphabet = "abcdefghijklmnopqrstuvwxyz"
test_dups = ["zzz","dog","bookkeeper","subdermatoglyphic","subdermatoglyphics"]
test_miss = ["zzz","subdermatoglyphic","the quick brown fox jumps over the lazy dog"]
# From Section 11.2 of: # Downey, A. (2015). Think Python: How to think like a computer scientist. Needham, Massachusetts: Green Tree Press.
def histogram(s):
d = dict()
for c in s:
if c not in d:
d[c] = 1
else:
d[c] += 1
return d
#Part 1 Write a function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters. Otherwise, it should return False.
def has_duplicates(stringP):
dic = histogram(stringP)
for key,value in dic.items():
if value>1:
return True
return False
# Implement has_duplicates by creating a histogram using the histogram function above. Write a loop over the strings in the provided test_dups list.
# Print each string in the list and whether or not it has any duplicates based on the return value of has_duplicates for that string.
# For example, the output for "aaa" and "abc" would be the following. aaa has duplicates abc has no duplicates Print a line like one of the above for each of the strings in test_dups.
print("***Implementation of has_duplicates fuction***")
for sTr in test_dups:
if has_duplicates(sTr):
print(sTr+": has duplicates")
else:
print(sTr+": has no duplicates")
#Part 2 Write a function called missing_letters that takes a string parameter and returns a new string with all the letters of the alphabet that are not in the argument string.
#The letters in the returned string should be in alphabetical order. Your implementation should use a histogram from the histogram function. It should also use the global variable alphabet.
#It should use this global variable directly, not through an argument or a local copy. It should loop over the letters in alphabet to determine which are missing from the input parameter.
#The function missing_letters should combine the list of missing letters into a string and return that string.
def missing_letters(sTr):
missingLettersList = []
dic = histogram(sTr)
for l in alphabet:
if l not in dic:
missingLettersList.append(l)
missingLettersList.sort()
return "".join(missingLettersList)
#Write a loop over the strings in list test_miss and call missing_letters with each string. Print a line for each string listing the missing letters.
#For example, for the string "aaa", the output should be the following. aaa is missing letters bcdefghijklmnopqrstuvwxyz
#If the string has all the letters in alphabet, the output should say it uses all the letters.
#For example, the output for the string alphabet itself would be the following. abcdefghijklmnopqrstuvwxyz uses all the letters
#Print a line like one of the above for each of the strings in test_miss.
print("\n***Implementation of missing_letters fuction***")
for lTm in test_miss:
sTr = missing_letters(lTm.replace(" ",""))
if sTr!="":
print(lTm+" is missing letters "+sTr)
else:
print(lTm +" uses all the letters")
