Answer:
(B) It allows an attacker to redirect targets to malicious webserver.
(D) It affects any clients querying the poisoned DNS server.
Explanation:
DNS cache poisoning is a serious type of attack that is designed to exploit the vulnerabilities inherent in a Domain Name Server (DNS) where a user is redirected from a real server to a fake one. It is also called DNS spoofing.
Normally, when your browser tries to visits a website through a given domain name, it goes through the DNS server. A DNS server maintains a list of domain names and their equivalent Internet Protocol addresses. This server (DNS) then responds to the request with one or more IP addresses for the browser to reach the website through the domain name.
The computer browser then get to the intended website through the IP address.
Now, if the DNS cache is poisoned, then it has a wrong entry for IP addresses. This might be via hacking or a physical access to the DNS server to modify the stored information on it. Therefore, rather than responding with the real IP address, the DNS replies with a wrong IP address which then redirects the user to an unreal website.
Although they might not be able to control your computer remotely as long as you are not trying to visit a web page via the poisoned information, there are other dangers attached to this type of attack.
Once the DNS server has been poisoned, any client trying to query the server will also be affected since there is no direct way of knowing if the information received from the server is actually correct.
Create an application in Java that asks a user for a number of hours, days, weeks, and years. It then computes the equivalent number of minutes (ignoring leap years).
Answer:
//import the Scanner class
import java.util.Scanner;
//Begin class definition
public class NumberOfMinutes{
//Begin main method
public static void main(String []args){
//Create an object of the Scanner class
Scanner input = new Scanner(System.in);
//initialize a variable nm to hold the number of minutes
int nm = 0;
//Prompt the use to enter the number of hours
System.out.println("Please enter the number of hours");
//Receive the input using the Scanner object and
//Store the entered number of hours in a variable nh
int nh = input.nextInt();
//Prompt the user to enter the number of days
System.out.println("Please enter the number of days");
//Receive the input using the Scanner object and
//Store the entered number of days in a variable nd
int nd = input.nextInt();
//Prompt the user to enter the number of weeks
System.out.println("Please enter the number of weeks");
//Receive the input using the Scanner object and
//Store the entered number of weeks in variable nw
int nw = input.nextInt();
//Prompt the user to enter the number of years
System.out.println("Please enter the number of years");
//Receive the input using the Scanner object and
//Store the entered number of years in a variable ny
int ny = input.nextInt();
//Convert number of hours to minutes and
//add the result to the nm variable
nm += nh * 60;
//Convert number of days to minutes and
//add the result to the nm variable
nm += nd * 24 * 60;
//Convert number of weeks to minutes and
//add the result to the nm variable
nm += nw * 7 * 24 * 60;
//Convert number of years to minutes and
//add the result to the nm variable
nm += ny * 52 * 7 * 24 * 60;
//Display the number of minutes which is stored in nm
System.out.println("The number of minutes is " + nm);
} //End main method
} //End of class definition
Sample Output:Please enter the number of hours

In the Stop-and-Wait flow-control protocol, what best describes the sender’s (S) and receiver’s (R) respective window sizes?
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."Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings. For each match, add one point to user_score. Upon a mismatch, end the game. Ex: The following patterns yield a user_score of 4: simonPattern: R, R, G, B, R, Y, Y, B, G, Y userPattern: R, R, G, B, B, R, Y, B, G, Y
Answer:
user_score = 0 #user score is initialized to 0
simonPattern = 'RRGBRYYBGY'# stores the sequence of characters in simonPattern
userPattern = input("Enter user pattern: ") # prompts the user to enter user pattern and stores the pattern in userPattern
for x in range(len(simonPattern)): #loops through entire length of simonPattern using x as index variable
if userPattern[x] == simonPattern[x]: # checks if the element at x-th index of userPattern matches the element at x-th index of simonPattern
user_score = user_score + 1 # adds 1 to user score if above if condition evaluates to true
else: #if a mismatch occurs
break #loop break if mismatch occurs
print("User Score:",user_score) #prints the computed user score
Explanation:
The program first declares a simonPattern string variable and assign it a sequence of characters. You can also prompt to enter the Simon pattern as
simonPattern = input("Enter Simon pattern:")
If you want to hard code the values of both simonPattern and userPattern then change the first two statements after user_score =0 statement as:
simonPattern = 'RRGBRYYBGY'
userPattern = 'RRGBBRYBGY'
Now I will explain the working of the for loop.
for x in range(len(simonPattern)):
len method is used which returns the length of the string stored in simonPattern. For example if simonPattern = 'RRGBRYYBGY' then len returns 10
range method is used to generate a sequence of numbers for x. This means value of x starts from 0 and it keeps incrementing to 1 until the length of the simonPattern is reached.
At first iteration:
Let suppose user enters the pattern: RRGBBRYBGY
x starts at index 0. Value of x=0 is less than the length of simonPattern i.e. 10 so the body of loop executes. The body of loop contains the following if statement:
if userPattern[x] == simonPattern[x]:
It matches both the string for the value of x.
if userPattern[0] == simonPattern[0]:
First character (at 0th index) of userPattern is R and in simonPattern is also R so this statement executes: user_score = user_score + 1 which adds 1 to the user_score. So user_score=1
Next iteration:
x=1
if userPattern[1] == simonPattern[1]:
Second character (at 1st index) of userPattern is R and in simonPattern is also R so this statement executes: user_score = user_score + 1 which adds 1 to the user_score. So user_score=2
Next iteration:
x=2
if userPattern[2] == simonPattern[2]:
Third character (at 12nd index) of userPattern is G and in simonPattern is also G so this statement executes: user_score = user_score + 1 which adds 1 to the user_score. So user_score=3
Next iteration:
x=3
if userPattern[3] == simonPattern[3]:
Fourth character (at 3rd index) of userPattern is B and in simonPattern is also B so this statement executes: user_score = user_score + 1 which adds 1 to the user_score. So user_score=4
Next iteration:
x=4
if userPattern[4] == simonPattern[4]:
Fifth character (at 4th index) of userPattern is B and in simonPattern is R so the if part does not execute and program moves to the else part which has a break statement which means the loop break. The next print(user_score) statement print the value of user_score. As user_score=4 computed in above iterations so output is:
User Score: 4
Answer:
The other answer was so close, but the _ was left out so the answer was wrong.
Written in Python:
user_score = 0
simon_pattern = input()
user_pattern = input()
for x in range(len(simon_pattern)):
if user_pattern[x] == simon_pattern[x]:
user_score = user_score + 1
else:
break
print('User score:', user_score)
Explanation:
When you use Word's Email option to share a document, you should edit the _____ line to let the recipient know the email is from a legitimate source.
Answer:
Subject line
Explanation:
Editing the subject line is very important so as to enable the recipient know the source of received the message (document).
For example, if a remote team working on a project called Project X receives a shared document by one member of team, we would expect the subject line of the email to be– Project X document. By so doing the legitimacy of the email is easily verified.
A number, a, is a power of b if it is divisible by b and a/b is a power of b. Write a function called is_power that takes parameters a and b and returns True if a is a power of b.
Answer:
Here is the Python program.
def is_power(a, b): # function that takes two positive integers a and b as arguments
if a == b: #first base case: if both the numbers are equal
return True #returns True if a=b
elif b==1: #second base case: if the value of b is equal to 1
return False #returns False if b==1
else: #recursive step
return a%b==0 and is_power(a/b, b) #call divisible method and is_power method recursively to determine if the number is the power of another
Explanation:
return a%b==0 and is_power(a/b, b) statement basically means a number, a, is a power of b if it is divisible by b and a/b is a power of b
In the statement return a%b==0 and is_power(a/b, b) , a%b==0 checks whether a number a is completely divisible by number b. The % modulo operator is used to find the remainder of the division. If the remainder of the division is 0 it means that the number a is completely divisible by b otherwise it is not completely divisible.
The second part of the above statement calls is_power() method recursively. The and operator between the two means that both of the parts of the statement should be true in order to return true.
is_power() method takes two numbers a and b as arguments. First the method checks for two base cases. The first base case: a == b. Suppose the value of a = 1 and b =1 Then a is a power of b if both of them are equal. So this returns True if both a and b are equal.
Now the program checks its second base case b == 1. Lets say a is 10 and b is 1 Then the function returns False because there is no positive integer that is the power of 1 except 1 itself.
Now the recursive case return return a%b==0 and is_power(a/b, b) takes the modulo of a and b, and is_power method is called recursively in this statement. For example if a is 27 and b is 3 then this statement:
a%b==0 is True because 27 is completely divisible by 3 i.e. 27 % 3 = 0
is_power(a/b,b) is called. This method will be called recursively until the base condition is reached. You can see it has two arguments a/b and b. a/b = 27/3 = 9 So this becomes is_power(9,3)
The base cases are checked. Now this else statement is again executed return a%b==0 and is_power(a/b, b) as none of the above base cases is evaluated to true. when a%b==0 is True as 9 is completely divisible by 3 i.e. 9%3 =0 and is_power returns (9/3,3) which is (3,3). So this becomes is_power(3,3)
Now as value of a becomes 3 and value of b becomes 3. So the first base case a == b: condition now evaluates to true as 3=3. So it returns True.
Now in order to check the working of this function you can call this method as:
print(is_power(27, 3))
The output is:
True
A signal travels from point A to point B. At point A, the signal power is 100 W. At point B, the power is 90 W. What is the attenuation in decibels?
Answer:
[tex]Attenuation = 0.458\ db[/tex]
Explanation:
Given
Power at point A = 100W
Power at point B = 90W
Required
Determine the attenuation in decibels
Attenuation is calculated using the following formula
[tex]Attenuation = 10Log_{10}\frac{P_s}{P_d}[/tex]
Where [tex]P_s = Power\ Inpu[/tex]t and [tex]P_d = Power\ outpu[/tex]t
[tex]P_s = 100W[/tex]
[tex]P_d = 90W[/tex]
Substitute these values in the given formula
[tex]Attenuation = 10Log_{10}\frac{P_s}{P_d}[/tex]
[tex]Attenuation = 10Log_{10}\frac{100}{90}[/tex]
[tex]Attenuation = 10 * 0.04575749056[/tex]
[tex]Attenuation = 0.4575749056[/tex]
[tex]Attenuation = 0.458\ db[/tex] (Approximated)

Multiply each element in origList with the corresponding value in offsetAmount. Print each product followed by a semicolon (no spaces). Ex: If the input is: 4 5 10 12 2 4 7 3 the output is: 8; 20;70; 36; 1 #include 2 3 int main(void) { 4 const int NUM_VALS = 4; 5 int origList[NUM_VALS]; 6 int offsetAmount [NUM_VALS]; 7 int i; 8 9 scanf("%d", &origList[0]); 10 scanf("%d", &origList[1]); 11 scanf("%d", &origList[2]); 12 scanf("%d", &origList[3]); 13 14 scanf("%d", &offsetAmount[0]); 15 scanf("%d", &offsetAmount[1]); 16 scanf("%d", &offsetAmount[2]); 17 scanf("%d", &offsetAmount[3]); 18 19 \* Your code goes here */ 20 21 printf("\n"); 22 23 return 0; 24
Answer:
Replace /* Your code goes here */ with
for(i =0; i<NUM_VALS; i++) {
printf("%d", origList[i]*offsetAmount[i]);
printf(";");
}
Explanation:
The first line is an iteration statement iterates from 0 till the last element in origList and offsetAmount
for(i =0; i<NUM_VALS; i++) {
This line calculates and print the product of element in origList and its corresponding element in offsetAmount
printf("%d", origList[i]*offsetAmount[i]);
This line prints a semicolon after the product has been calculated and printed
printf(";");
Iteration ends here

Recall that within the ArrayBoundedQueue the front variable and the rear variable hold the indices of the elements array where the current front and rear elements, respectively, of the queue are stored. Which of the following code sequences could be used to correctly enqueue element into the queue, assuming that enqueue is called on a non-full queue and that the code also correctly increments numElements?
a. numElements++; elements[rear) - element:
b. front++; elements(front) - element:
c. rear = (rear + 1) % elements.length; elements[rear) - element;
d. front = (front + 1) % elements.length; elements[front) - element;
Answer:
c. rear = (rear + 1) % elements.length; elements[rear] = element;
Explanation:
In the above statement:
Name of the array is elements.
rear holds current index of elements array where current rear element of queue is stored. Front are rear are two open ends of the queue and the end from which the element is inserted into the queue is called rear.
element is the element that is required to enqueue into the queue
Enqueue basically mean to add an element to a queue.
Here it is assumed that the queue is not full. This means an element can be added to the queue.
It is also assumed that code also correctly increments numElements.
rear = (rear + 1) % elements.length; This statement adds 1 to the rear and takes the modulus of rear+1 to the length of the array elements[]. This statement specifies the new position of the rear.
Now that the new position of rear is found using the above statement. Next the element can be enqueued to that new rear position using the following statement:
elements[rear] = element; this statement sets the element at the rear-th (new position) index of elements[] array.
For example we have a queue of length 5 and there are already 4 elements inserted into this queue. We have to add a new element i.e. 6 to the queue. There are four elements in elements[] array and length of the array is 5 so this means the queue is not full. Lets say that rear = 3
elements.length = 5
rear = 3
Using above two statements we get.
rear = (rear + 1) % elements.length;
= 3 + 1 % 5
= 4%5
= 4
This computes the new position of rear. So the new position of rear is the 4-th index of elements[]. Now next statement:
elements[rear] = element;
elements[4] = 6
This statement adds element 6 to the 4-th index of elements[] array.
Thus the above statement enqueues element (element 6 in above example) into the queue.
If distances are recorded as 4-bit numbers in a 500-router network, and distance vectors are exchanged 3 times/second, how much total bandwidth (in bps) is used by the distributed routing algorithm
Answer:
A total of 6,000 bps of bandwidth is used by the distributed routing algorithm
Explanation:
This is a bandwidth requirement question.
We proceed as follows;
To calculate the total number of bits for a routing table, we use the following formula;
Routing table=Number of routers * length of cost
we are given the following parameters from the question;
Number of routers = 500
length of cost = 4 bits
Routing table = 500*4
=2000
Hence, a routing table is 2000 bits in length.
Now we proceed to calculate the bandwidth required on each line using the formula below;
Bandwidth = no.of seconds * no.of bits in routing table
Bandwidth required on each line = 3*2000
=6000

Assume a PHP document named hello.php has been saved in a folder named carla inside the htdocs folder on your computer. Which is the correct path to enter to view this page in a browser?
The available options are:
A. localhost/Carla/hello.php
B. localhost/htdocs/hello.php
C. localhost/htdocs/Carla/hello.php
D. carla/hello.php5
Answer:
C. localhost/htdocs/Carla/hello.php
Explanation:
A path in computer programming can be defined as the name of a file or directory, which specifies a unique location in a file system.
Therefore, to get the correct path to enter to view this page in a browser, one needs to follow the directory tree hierarchy, which is expressed in a string of characters in which path components, separated by a delimiting character, represent each directory.
Hence, correct path to enter to view this page in a browser is "localhost/htdocs/Carla/hello.php"

return result_string
#if you want to see the working of this function then you can call this function using the following statements:
target_string = "In case I don't see ya, good afternoon, good evening, and good night!"
find_string = "good"
replace_string = "bad"
print(replace_all(target_string, find_string, replace_string)
Explanation:
The above program has a function called replace_all that accepts three arguments i.e target_string, a string in which to search ,find_string, a string to search for and replace_string, a string to use to replace every instance of the value of find_string. The function has the following statement:
replace_string.join(target_string.split(find_string))
split() method in the above statement is splits or breaks the target_string in to a list of strings based on find_string. Here find_string is passed to split() method as a parameter which works as a separator. For example above:
target_string = In case I don't see ya, good afternoon, good evening, and good night!
find_string = good
After using target_string.split(find_string) we get:
["In case I don't see ya, ", ' afternoon, ', ' evening, and ', ' night']
Next join() method is used to return a string concatenated with the elements of target_string.split(find_string). Here join takes the list ["In case I don't see ya, ", ' afternoon, ', ' evening, and ', ' night'] as parameter and joins elements of this list by 'bad'.
replace_string = bad
After using replace_string.join(target_string.split(find_string)) we get:
In case I don't see ya, bad afternoon, bad evening, and bad night!

int a,b,c;//defining integer variable
int k=1;//defining integer variable k that holds a value 1
while(k<=8)//defining while loop for 8 time input
{
printf("Please insert 3 numbers in (0 0r 1):\n ");//print message
scanf("%d%d%d", &a, &b, &c);//input value
k++;//increment the value of k by 1
printf("value: %d\n",AND(OR(a,b),c));
}
return 0;

Explanation:
In the above-given C language code two methods "AND and OR" is declared, holds two integer variable "x and y" in its parameters, inside the method a conditional it used that can be defined as follows:
In the AND method, inside a conditional statement, if block check x and y both value is same that is 1 it will return 1 or it will goto else block in this it will return value 0. In the OR method, inside a conditional statement, if block check x and y both value is the same, that is 0 it will return 0 or it will goto else block in this it will return value 1.In the main method, four integers "a,b,c, and k" is declared in which variable "a, b, c" is used in the loop for 8 times input values from the user and print method is used to call the method and prints its return values.#Write a function called after_second that accepts two #arguments: a target string to search, and string to search #for. The function should return everything in the first #string *after* the *second* occurrence of the search term. #You can assume there will always be at least two #occurrences of the search term in the first string. # #For example: # after_second("11223344554321", "3") -> 44554321 # #The search term "3" appears at indices 4 and 5. So, this #returns everything from the index 6 to the end. # # after_second("heyyoheyhi!", "hey") -> hi! # #The search term "hey" appears at indices 0 and 5. The #search term itself is three characters. So, this returns #everything from the index 8 to the end. # #Hint: This may be more complicated than it looks! You'll #have to look at the length of the search string and #either modify the target string or take advantage of the #extra arguments you can pass to find(). #Write your function here!
Answer:
Following are the code to this question:
def after_second(s,sub):#defining a method a fter_second
first = s.find(sub)#defining a variable first that hold method find value
if first != -1:#defining if block to check first variable value not equal to -1 using slicing
s = s[len(sub)+first:]#defining s variable to calculate sub parameter length of parameter and use slicing
second = s.find(sub)#defining second variable to calculate find method value
if second != -1:#defining if block to calculate second variable slicing
return s[len(sub)+second:]#return s variable value
print(after_second("heyyoheyhi","hey"))#defining print method to call after_second method
print(after_second("11223344554321","3"))#defining print method to call after_second method
Output:
hi
44554321
Explanation:
In the above python code a method "after_second" is declared, that accepts two-variable "s, and sub" as the parameter inside the method a first variable is declared that uses the inbuilt method "find" to find the value and stores it value. In the next step, two if blocks are used, in which both if blocks use the slicing to checks its value is not equal to "-1".
In the first, if block the first variable is declared that uses the s variable to calculate subparameter length by using slicing and defines the second variable that finds its value and stores its value. In the next, if block the s variable is used to return its calculated value, and at the end of the print, the method is used to call the method by passing parameter value and prints its return value.Which of these statements are true about managing through Active Directory?
