Advanced Sounds is engaging in a full upgrade of its Windows Server 2003 network to Windows Server 2008. The upgrade includes using Windows Server 2008 Active Directory. Advanced Sounds has pioneered many technological innovations and is very concerned about keeping its network and computer systems secure. Advanced Sounds Information Technology (IT) Department hires you to help them implement Windows Server 2008 Active Directory. Assume the following:
All email servers have been consolidated back in the New York City Complex.
Most all the other applications running on Windows Servers are distributed at all sixteen locations.
Each location at minimum has a file server, a print server and a local application server.
All locations have adequate Wide Area network connections with available capacity; 10 Mbps links
The New York location has enough network capacity to serve all 16 locations.
There are 500 people at the New Your City complex.
There are 200 people at the Quebec City location and 200 at the Montreal location.
There are 40-50 people at each outlet store.
Advanced Sounds IT Department has formed a small installation planning committee consisting of the IT server operations manager, two system programmers, the current Active Directory administrator, and you. After the first meeting they have asked you to prepare a small report to address the following questions:
A. What information is required as input to the initial installation involving Active Directory? a=
B. How many Active directory servers do you propose?
C. Where will the Active directory server(s) be located?

The beginning of a free space bitmap looks like this after the disk partition is first formatted: 1000 0000 0000 0000 0000 0000 0000 0000 (the first block is used by the root directory). The system always searches for free blocks starting at the lowest numbered block, so after writing file A, which uses 8 blocks, the bitmap looks like this 1111 1111 1000 0000 0000 0000 0000 0000. Show the bitmap after each of the following actions: (a) File B is written, using 12 blocks (b) File C is written, using 7 blocks (c) File A is deleted (d) File B is deleted (e) File D is written, using 6 blocks (f) File E is written, using 9 blocks Show all steps.
The bitmap is 1110 0000 0001 0000 after some use. The system always looks for free blocks beginning using a contiguous allocation technique.
What is a bitmap?After some use, the new bitmap is 1110 0000 0001 0000. The system employs a contiguous allocation mechanism and starts searching for free blocks at the position.
(a) File B is made up of five blocks, 1111 1111 1111 0000.
b) The batch number 1000 0001 1111 0000 deletes File A.
c) Eight blocks are used for writing in file C.
1111 1111 1111 1100
File B is deleted (d). 1111 1110 0000 1100
Free-space bitmaps are one method used by some file systems to keep track of allocated sectors. Even though the most fundamental implementation of free-space bitmaps is incredibly wasteful, some modern file systems use complex or hybrid versions of them.
Therefore, after some use, the bitmap is 1110 0000 0001 0000. The contiguous allocation strategy is always used by the system to look for free blocks to start with.

Which of the following meanings of the plus sign, +, are built-in to the language (and/or standard libraries or classes that we have been using with the language)?
A. Numeric subtraction
B. Numeric addition
C. string concatenation
D. The logical "or" operation
Answer:
Numeric Addition
Explanation:
Literally, the + sign is an arithmetic operator used to perform addition operation between numeric datatypes (integer, float, decimal, double, long integer, etc...)
Its default built in function of the plus is sign is to add variables, constants and/or expressions.
The plus sign is used as follows;
a = 5;
b = 3;
c = a + b
-------------
a + b = 5 + 3 = 8
8 will be saved in variable c. This is only possible using the plus sign.
The plus sign also has other function such as string concatenation but this function is language dependent (i.e. some programming languages do not use + for string concatenation).
Conclusively, the built in function of the plus sign is for numeric addition

Write a program that asks the user to enter either an "African" or a "European" swallow. The programâs behaviour should mimic the program below. If the user enters something øther than "African" or "European", the program shøuld insult the user like the example below.
Sample Output #1:
What kind of swallow?
African
Yes, it could grip it by the husk.
Sample Output #2:
What kind of swallow?
European
A five-ounce bird could not carry a one-pound coconut.
Sample Output #3:
What kind of swallow?
Spanish
You really are not fit to be a king.
Answer:
The programming language is not stater; However, I'll answer this question using C++.
This program does not use comments (See explanation)
See Attachment for program file
Program starts here
#include <iostream>
using namespace std;
int main()
{
string response;
cout<<"What kind of swallow?\n";
cin>>response;
for(int i =0; i<response.length();i++)
{
response[i]=toupper(response[i]);
}
if(response == "AFRICAN")
{
cout<<"Yes, it could grip it by the husk.";
}
else if(response == "EUROPEAN")
{
cout<<"A five-ounce bird could not carry a one-pound coconut.";
}
else
{
cout<<"You really are not fit to be a king.";
}
return 0;
}
Explanation:
string response; -> A string variable to hold user input is declared
cout<<"What kind of swallow?\n"; -> prompts user for input
cin>>response; -> user input is stored here
The following iteration converts user input to uppercase; so that the program will work for inputs like African, AFRICAN, AFriCAN, etc.
for(int i =0; i<response.length();i++)
{
response[i]=toupper(response[i]);
}
The following if statement prints "Yes, it could grip it by the husk." if user input is AFRICAN
if(response == "AFRICAN")
{
cout<<"Yes, it could grip it by the husk.";
}
Otherwise, if user input is EUROPEAN, it prints; "A five-ounce bird could not carry a one-pound coconut."
else if(response == "EUROPEAN")
{
cout<<"A five-ounce bird could not carry a one-pound coconut.";
}
Lastly; for every inputs different from AFRICAN and EUROPEAN, the program displays "You really are not fit to be a king."
else
{
cout<<"You really are not fit to be a king.";

Assume passwords are selected from four character combinations of 26 lower case alphabetic characters. Assume an adversary is able to attempt passwords at a rate of 1 per second. Assuming feedback to the adversary flagging an error as each incorrect character is entered, what is the expected time to discover the correct password
Answer:
Given:
Passwords are selected from 4 characters.
Character combinations are 26 lower case alphabetic characters.
Passwords attempts by adversary is at rate of 1 second.
To find:
Expected time to discover the correct password
Explanation:
Solution:
4 character combinations of 26 alphabetic characters at the rate of one attempt at every 1 second = 26 * 4 = 104
So 104 seconds is the time to discover the correct password. However this is the worst case scenario when adversary has to go through every possible combination. An average time or expected time to discover the correct password is:
13 * 4 = 52
You can also write it as 104 / 2 = 52 to discover the correct password. This is when at least half of the password attempts seem to be correct.
The common field cricket chirps in direct proportion to the current temperature. Adding 40 to the number of times a cricket chirps in a minute, then dividing by 4, gives us the temperature (in Fahrenheit degrees). Write a program that accepts as input the number of cricket chirps in fifteen seconds, then outputs the current temperature
Answer:
This program is written in Java programming language;
First, you should understand that:
The formula given in the question implies that the current temperature can only be calculated using measurement of time in minutes;
Given that the number of chirps is directly proportional to the temperature.
If the cricket made n chirps in 15 seconds, it will make n * (60/15) chirps in 1 minutes;
n * (60/15) = n * 4
Base on this analysis, the program is as follows
import java.util.*;
public class cricket
{
public static void main(String []args)
{
//Declare number of chips in 1 minutes
int num;
Scanner input = new Scanner(System.in);
//Prompt user for input
System.out.print("Number of chirps (in 15 seconds): ");
num = input.nextInt();
//Calculate temperature (multiply temperature by 4 to get number of chirps in minutes
double temp = (num * 4+ 40)/4;
//Print temperature
System.out.print("Current Temperature = "+temp+" F");
}

Given: The following if statement uses an overloaded > operator to determine whether the price of a Car object is more than $5000. Car is a struct and myCar is an object of Car. Each Car object has two variables: id (int) and price (float). As you can see in the following code, the ID of myCar is 12345 and the price is $6,000.
Car myCar = {12345, 6000.};
float price = 5000;
if (myCar > price)
cout << "My car price is more than $5,000.\n";
Which one of the following function prototypes is correct syntax to overload the > operator based on the if statement above.
a. void operator>(float price);
b. bool operator>(Car& car, float price);
c. bool operator >(float amt);
d. bool operator>(Car& yourCar);
e. none of the above
Answer:
Option(c) is the correct answer to the given question.
Explanation:
In the given question car is the structure and mycar is the instance or the object of the class also the object mycar holds two variables of type integer and the one float variable .
Following are the syntax of operator overload in C++ programming language
return -type operator operator-symbol(datatype variable name )Now according to the question the option(c) follows the correct syntax of operator overload
All the other option do not follow the correct prototype that's why these are incorrect option .
The degree of a point in a triangulation is the number of edges incident to it. Give an example of a set of n points in the plane such that, no matter how the set is triangulated, there is always a point whose degree is n−1.
Answer:
squarepentagonExplanation:
The vertices of a square is one such set of points. Either diagonal will bring the degree of the points involved to 3 = 4-1.
The vertices of a regular pentagon is another such set of points. After joining the points in a convex hull, any interior connection will create a triangle and a quadrilateral. The diagonal of the quadrilateral will bring the degree of at least one of the points to 4 = 5-1.
Write a calling statement for the following code segment in Java: public static int sum(int num1, int num2, String name) { int result = num1 + num2; System.out.println("Hi " + name + ", the two numbers you gave me are: " + num1 + " " + num2); return result; } Function Integer sum(Integer num1, Integer num2, String name) Integer result = num1 + num2 Display "Hi " + name + ", the two numbers you gave me are: ", num1, " ", num2 Return result End Function Write a calling statement to the function in Java or Pseudocode. You may use any value of appropriate data samples to demonstrate your understanding.
Answer:
Following are the calling of the given question
public static void main(String[] args) // main function
{
int store; // variable declaration
store = sum(32,15,"san"); // Calling of sum()
System.out.println(" TheValue returned by sum() : "+store); // display
}
Explanation:
Following are the description of the above statement
Here is the name of function is sum() In the sum() function definition there are 3 parameter in there signature i.e two "int" type and 1 is "string" type .In the main function we declared the variable store i,e is used for storing the result of sum() it means it storing the result of value that is returning from the definition of sum() function .After that calling the function by there name and passing three parameter under it sum(32,15,"san"); and store in the "store" variable.Finally print the value by using system.out.println ().Computers in a LAN are configured to use a symmetric key cipher within the LAN to avoid hardware address spoofing. This means that each computer share a different key with every other computer in the LAN. If there are 100 computers in this LAN, each computer must have at least:
a. 100 cipher keys
b. 99 cipher keys
c. 4950 cipher keys
d. 100000 cipher keys
Answer:
The correct answer is option (c) 4950 cipher keys
Explanation:
Solution
Given that:
From the given question we have that if there are 100 computers in a LAN, then each computer should have how many keys.
Now,
The number of computers available = 100
The number of keys used in symmetric key cipher for N parties is given as follows:
= N(N-1)/2
= 100 * (100 -1)/2
= 50 * 99
= 4950 cipher keys
In this challenge you will use the file regex_replace_challenge_student.py to:
Write a regular expression that will replace all occurrences of:
regular-expression
regular:expression
regular&expression
In the string: This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression
Assign the regular expression to a variable named pattern
Using the sub() method from the re package substitute all occurrences of the 'pattern' with 'substitution'
Assign the outcome of the sub() method to a variable called replace_result
Output to the console replace_results
Regular Expression Replace Challenge
The Python statement containing the string to search for the regular expression occurrence is below. search_string=’’’This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression’’’

Universal Containers (UC) is currently live with Sales Cloud and in the process of implementing Service Cloud. UC wants to create a sandbox to test its Service Cloud implementation with real Sales Cloud data. Which three Sandbox types can be used to accomplish this? Choose 3 answersA. Administrator SandboxB. Partial Copy SandboxC. Full SandboxD. Developer k Pro SandboxE. Test Sandbox
Answer:
B. Partial Copy Sandbox
C. Full Sandbox
D. Developer k Pro Sandbox
Explanation:
In this scenario Universal containers wants to implement a service cloud and test with real Sales Cloud data.
Service cloud is defined a system that allows automation of various customer service functions. It can listen to customers via different social media platforms and direct customers to agents that can solve their problems.
Sandbox is a testing environment that is isolated and allows for running of programs without affecting the application.
To test service cloud implementation with real data we use the following 3 sandboxes:
- Partial copy sandbox: copies only relevant data to test configurations with real data.
- Full Sandbox: makes a replica of data by copying all data such as attachments, metadata, and object records.
- Developer K pro sandbox: is used by developers to test software in an isolated environment and can use large data sets. It includes configuration data (metadata)
