You manage a Windows server that has an attached printer that is used by the Sales department. The sales manager has asked you to restrict access to the printer as follows:Sally needs to connect to a printer, print documents, and pause and resume her own print jobs.Damien needs to pause and resume documents for all users, but does not need to change printer properties.You want to assign the most restrictive permissions that meet the sales manager's requirements. What should you do
Answer:
Damien would be assign the Manage Documents permission while Sally on the other hand will be assign the permission to print.
Explanation:
Based on the information given in order for me to assign a restrictive permission that will meet the requirements of the sale manager's what I will do is for me to assign the Manage Documents permission to Damien reason been that Damien only needs to stop and resume the documents for all users in which he does not need to change the printer properties and to assign the permission to print to Sally reason been that Sally only needs to connect to a printer and to print documents in which she will then stop and resume her own print jobs.

This is similar to the last problem, except that the first number on a line is an ID number that identifies an account. The same ID number may appear on any number of lines. Use a Dictionary to accumulate, for each ID, the sum of all the numbers that are on all the lines with that ID number. Call the input file id_data.txt. Write an output file called ID_sums.txt. On each line of the output fille, print an ID number and the sum. Sort the lines by the numerical order of the IDs
Answer:
Following are the code to this question:
def getSum(ID):#defining a method getSum that accept an ID
t= 0#defining a variable t
while ID!= 0:#defining while loop to check ID not equal to 0
t+= ID % 10# holding remainder value
ID = ID // 10#holding quotient value
return t#return total value
def readRecord(S):#defining a method readRecord that hold list
f_Read = open("idInfo.txt","r")#defining a variable f_Read to open file
for C_ID in f_Read:#defining for loop to hold file value
C_ID = C_ID.replace('\n', '')#use replace method
S[C_ID] = getSum(int(C_ID))#use list to method value
f_Read.close()#close file
def sortRecord(ID_List, t_List):#defining a sortRecord
for x in range(len(ID_List) - 1):#defining for loop to calculate the length of list
for y in range(0, len(ID_List) - x - 1):#defining for loop to calculate the length of list
if ID_List[y] > ID_List[y+1]:#defining if block to check value is greater
ID_List[y], ID_List[y+1] = ID_List[y+1], ID_List[y]#swap the value
t_List[y], t_List[y+1] = t_List[y+1], t_List[y]#swap the value
def showReport(ID, t):#defining a method showReport that accept id and t
for i in range(len(ID)):#defining for loop to hold index value
print(ID[i]," ",t[i])#print index value
def writeRecord(ID_List, t_List):#defining a method writeRecord that accept two list
f_Write = open("idSorted.txt","w")#defining a variable f_Write to hold store value in file
for i in range(len(ID_List)):#defining a for loop to store value with index
f_Write.write(ID_List[i])#hold list value
f_Write.write(" ") #for space
f_Write.write(str(t_List[i]) + "\n")# add index value
f_Write.close()#close file
def run():#defining method run
S = {}#defining an empty list
readRecord(S)#passing list into readRecord method
ID_List = list(S.keys())#defining a variable that holds key value in list
t_List = list(S.values())#defining a variable that holds values value in list
sortRecord(ID_List, t_List)#calling a method sortRecord by passing value
showReport(ID_List, t_List)#calling a method showReport by passing value
writeRecord(ID_List, t_List)#calling a method writeRecord by passing value
if "run":
run()
Output:
Please find the attached file.
Explanation:
In the above program code, 6 method getSum, readRecord, sortRecord,showReport, writeRecord, and run method is defined, in which getSum and readRecord is used a single list store value in parameters, and in other methods, it accepts two parameter to store value in key and values form and use a txt file to store and take value.
In the run method, an empty list s is declared, that pass into the variable ID_List and t_List, and call the method, in this program two a text file "idInfo.txt" is used, that holds some value in the file, and create another file that is "idSorted.txt", in this file it stores the value in the numerical order of the ID's.
Jorge is sending a message to Thomas but would like a copy sent to his external email address as well. Jorge does not want Thomas to see this copy that was sent.
Which mail field will Jorge use to achieve this goal?
To:
From:
CC:
BCC:
Answer: BCC (fourth choice)
=================================================
Explanation:
CC stands for "carbon copy".
BCC stands for "blind carbon copy".
Filling out forms is a tedious process. It's even more tedious when you have to repeat yourself multiple times. Carbon copy paper technology allows you to fill out one form and have those inputted entries be copied to the layers below. In terms of email, a carbon copy (CC) email is just an email sent to more than one person. In the CC line, recipients can see who the other people are in the email chain.
In contrast, a blind carbon copy is where the recipients cannot see who is in the BCC line. This allows Jorge to send the message copy to an external address without Thomas knowing.

A specific packet journey, from your computer to a remote server, end-to-end across multiple networks, has the following link bandwidths (packet travels across each of these links, in order): 1000 Mbps, 1 Mbps, 40 Mbps, 400 Mbps, 100 Mbps, 1000 Mbps. Assuming your computer and the server can transfer data at > = 1000 Mbps (so neither device is limiting the data transfer relative to the links), how long, in seconds, will it take to transfer a 125 MB file?
Answer:
0.125 seconds
Explanation:
The formula for the time taken to transfer the file is = file size / bandwidth
Assuming the computer and server could only transfer data at the speed of 1000 Mbps or more, The time of transmission is;
= 125 MB / 1000 Mbps = 0.125 seconds.

A hacker successfully modified the sale price of items purchased through your company's web site. During the investigation that followed, the security analyst has verified the web server, and the Oracle database was not compromised directly. The analyst also found no attacks that could have caused this during their log verification of the Intrusion Detection System (IDS). What is the most likely method that the attacker used to change the sale price of the items purchased
Answer:
By modifying the hidden form values that is in a local copy of the company web page
Explanation:
In a situation were the hacker successful change the price of the items he/she purchased through the web site of the company's in which the company web server as well as the company Oracle database were not compromised directly which means that the most likely method in which the attacker used to modified the sale price of the items he/she purchased was by modifying the HIDDEN FORM VALUE that was in the local copy of the company web page making it easy for the HIDDEN FORM VALUE to be vulnerable to the hacker because the hidden form value did not store the company server side information or data but only store the company software state information which is why HIDDEN FORM VALUE should not be trusted.
what type of collection is used in the assignment statement
info: [3:10,4:23,7:10,11:31]
tuple
list
Duque
dictionary
Answer:
The correct answer to this question is given below in the explanation section.
Explanation:
There are four data types in Python used to store data such as tuple, list, set, and dictionary.
The correct answer to this question is option D: Dictionary
Dictionary data type is used to store data values in key:value pairs as given in the question. It is a collection that is changeable, unordered, and does not allow duplicate entries.
Dictionaries in Python are written with curly brackets and have keys and values such as car={name="honda", model=2010}
when you run the given assignment statment such
info= {3:10,4:23,7:10,11:31}
print(info)
It will print the info dictionary (key:value pair)
{3: 10, 4: 23, 7: 10, 11: 31}
While other options are not correct because:
Tuples in Python are used to store multiple items in a single variable. For example:
info=("apple", "banana", "cherry")
List is used to store multiple items in a single variable. for example
myList = ["apple", "banana", "cherry"]
print(myList)
The list is ordered, changeable, and allows duplicate entry. But you can not put key: value pair in the list.

Write a version of the sequential search algorithm that can be used to search a sorted list. Write a program to test the sequential search algorithm. Use either the function bubbleSort or insertionSort to sort the list before the search. Your program should prompt the user to enter 10 digits and then prompt the user to enter a digit to search - if the list contains this digit, output its position to the console:
Answer:
#include <iostream>
using namespace std;
void insertionSort(int myArr[]){
int currentvalue, position;
for (int i = 1; i < myArr.size(); ++i){
currentvalue = myArr[i] ;
position = i;
while (position>0 and myArr[position-1]>currentvalue){
myArr[position]= myArr[position-1] ;
position = position-1 ;
}
myArr[position]= currentvalue;
}
}
int main(){
int numberList[10], search;
for (int x = 0; x < 10; ++x){
cin>> numberList[x];
}
insertionSort(numberList);
cout << "Enter the search term/number: ";
cin>> search;
for (int i = 0; < 10; ++x){
if (search == number[i]){
cout<< i;
break;
} else {
cout<< "Number does not exist.";
}
}
}
Explanation:
The C++ source code defines the insertionSort void function, then prompts the user ten times to fill the array numberList. It uses the insertion sort algorithm to sort the array of ten items and then a number is searched using a sequential search algorithm.
Which of the following calculates to 10?
3*(6+2/2)
(3* 6) + 2/2
(3* 6+ 2)/2
3*6+2/2
Answer:
C. (3* 6+ 2)/2
Explanation:
Arithmetic operation are performed sequentially using the rule known as bracket of division, multiplication, addition and subtraction (BODMAS).
(3* 6 + 2)/2
Simplifying the above mathematical expression, we have;
(18 + 2)/2
= 20/2 = 10
Adam is so good at playing arcade games that he will win at every game he plays. One fine day as he was walking on the street, he discovers an arcade store that pays real cash for every game that the player wins - however, the store will only pay out once per game. The store has some games for which they will pay winners, and each game has its own completion time and payout rate. Thrilled at the prospect of earning money for his talent, Adam walked into the store only to realize that the store closes in 2 hours (exactly 120 minutes). Knowing that he cannot play all the games in that time, he decides to pick the games that maximize his earnings
Sample game board at the arcade GAME COMPLETION TIME (in minutes) PAYOUT RATE Pac-man 90 400 Mortal Kombat 10 30 Super Tetris 25 100 Pump it Up 10 40 Street Fighter II 90 450 Speed Racer 10 40
An acceptable solution is the one where it still picks the best earnings even when the list of games or completion times or payout rates change.
Question:
Write code in Java/Scala/Python to help Adam pick the sequence(s) of games that earn him the most money?.
Then, assume you have a variable list of games and their payout rates. What is the best way to pick the games that earn you the most?
Input Explanation
The first line of input is always an integer denoting many lines to read after the first line. In our sample test case, we have 6 in the first line and 6 lines after the first line, each having a game, completion_time and payout_rate.
In each data line, the game, completion_time and payout_rate are separated by a ','(comma).
The games board may change but the store still closes in 120 minutes.
Input

Jordan uses a spreadsheet to keep track of how many hits each player on a baseball team has had in each game
throughout the season. For every game, each player's name appears in a column that Jordan has titled "Player."
Next to that, a column titled "Hits" shows the number of hits for each player in a single game.
What function should Jordan use to find the average number of hits per game for player A_Clemente?
O SUMIF(Hits, "A Clemente", Player)
O SUMIF(Player, "A Clemente". Hits)
O AVERAGEIF(Hits, "A Clemente", Player)
O AVERAGEIF(Player,"A_Clemente", Hits)
Answer:
AVERAGEIF(Player, "A_Clemente", Hits)
Explanation:
The AVERAGEIF function allows users to calcule the mean value of numerical columns while also Given certain constraints within a single function call. The AVERAGEIF takes in 3 arguments.
The first is a column which houses the range of the constraint we would like to apply on our function.
The second argument is the constraint itself which should reside within the values in the range defined in the first argument.
The third argument is the numerical column whose average is calculated based on the defined constraint.
Therefore, in the scenario above, Player is the column containing player names, which it's value will later be used as a constraint
"Clemente_A" the constraint, only values pertaining to Clemente_A will be defined.
Hits, the numeric column whose value is averaged based on the constraint given.

Write a program that declares three one-dimensional arraysnamed miles, gallons, and mpg. Each array should be declared in main() and should becapable of holding ten double-precision numbers. The numbers that should be stored in miles are240.5, 300, 189.6, 310.6, 280.7, 206.9, 199.4, 160.3, 177.4, and 192.3. The numbers should bestored in gallons are 10.3, 15.6, 8.7, 14, 16.3, 15.7, 14.9, 10.7, 8.3, and 8.4.
Answer:
#include <iostream>
using namespace std;
int main(){
double miles[10] = {240.5, 300, 189.6, 310.6, 280.7, 206.9, 199.4, 160.3, 177.4, 192.3};
double gallons[10] = {10.3, 15.6, 8.7, 14, 16.3, 15.7, 14.9, 10.7, 8.3, 8.4};
double mpg[10];
for (int i = 0; i < 10; i++){
mpg[i] = miles[i]/ gallons[i];
cout << "mpg: " << mpg[i] << endl;
}
}
Explanation:
The C++ source code declares three arrays miles, gallons and mpg with an array length of 10. The gallons and miles arrays are assigned 10 array items each and they are used to push values to the mpg array in the for loop statement. The result of each item in the mpg array is displayed on the screen.
