Complete Question:

Different network scenarios require the use of different tools. The tools you may consider should EXCLUDE:

a. Port scanner

b. Banner grabbing tools

c. Vulnerability scanner

d. Honeypots

e. Protocol analyzer

f. Viruses

g. Honeynets

Answer:

f. Viruses

Explanation:

Different network scenarios require the use of different tools. The tools you may consider should include:

a. Port scanner: this is a program used by network administrators to scan various application, transport, internet and network ports which may be exploited by hackers or attackers when found vulnerable.

b. Banner grabbing tools: it is used to gather informations of a computer residing on a network and various services running on its open ports using telnet, zmap, netcat and nmap.

c. Vulnerability scanner: used for the detection of vulnerabilities in a network or systems.  

d. Honeypots: it is used to detect and redirect or prevent any unauthorized use of information of a network by mimicking the potential target systems.

e. Protocol analyzer: it is used to analyze traffic and packet captures in a network. Software programs such as wireshark, tshark can be used for protocol analysis.

f. Honeynets: is a combination of one or more honeypots used for attracting and trapping potential attackers.

However, a virus is a malicious program that can replicate and cause severe damage to a computer system.

Answer:

Here is the C++ program:

#include <fstream>  //to create, write and read a file

#include <iostream>  // to use input output functions

using namespace std;  //to access objects like cin cout

const int MAXNAME = 20;  //MAXNAME is set to 20 as a constant

int main(){  //start of main() function

ifstream inData;  //creates an object of ifstream class

inData.open("grades.txt");  //uses that object to access and opens the text file using open() method

char name[MAXNAME + 1];   // holds the names

float average;   //stores the average

inData.get(name,MAXNAME+1);  //Extracts names characters from the file and stores them as a c-string until MAXNAME+1 characters have been extracted

while (inData){  //iterates through the file

 inData >> average;  //reads averages from file using the stream extraction operator

 cout << name << " has a(n) " << average << " average." << endl; //prints the names along with their averages

 inData.ignore(50,'\n');  //ignores 50 characters and resumes when  new line character is reached. It is used to clear characters from input buffer

 inData.get(name,MAXNAME+1);}  //keeps extracting names from file

return 0; }

Explanation:  

The program is well explained in the comments added to each line of the code. The program uses fstream object inData to access the grades.txt file. It gets and extracts the contents of the file using get() method, reads and extracts averages from file using the stream extraction operator. Then program displays the names along with their averages from grades.txt on output screen.

The grades.txt file, program and its output is attached.

Answer:

public void printAll(){  // member function petAll()

   super.printAll();  //  calls printAll() method of the superclass (base class) AnimalData using super keyword

   System.out.print(", ID: " + idNum);} // prints the ID stored in the idNum data member of the PetData class

Explanation:

Here is the complete PetData class:

public class PetData extends AnimalData {  //

private int idNum;

public void setID(int petID) {

idNum = petID;  }

// FIXME: Add printAll() member function

/* Your solution goes here */

public void printAll(){

   super.printAll();

   System.out.print(", ID: " + idNum);}  }

PetData class is a subclass which is inherited from the base class AnimalData.

This class has a private data member which is the variable idNum which is used to store the ID value.

It has a member function setID with parameter petID which is the idNum. This method basically acts as a mutator and sets the user ID.

This class has another method printAll() that uses super keyword to access the method printAll() of the base class which is AnimalData

super basically refers to the base class objects.

Here the super keyword is used with the method name of subclass PetData in order to eliminate the confusion between the method printAll() of AnimalData and PetData since both have the same method name.

In the main() method the use is prompted to enter values for userName, UserAge and UserID. Lets say user enters Fluffy as user name, 5 as user age and 4444 as userID. Then the statement userPet.printAll(); calls printAll() method of PetData class as userPet is the object of PetData class.

When this method is called, this method calls printAll() of AnimalData class which prints the Name and Age and printAll() of PetData class prints the ID. Hence the program gives the following output:

Name: Fluffy, Age: 5, ID: 4444    

The program illustrates the use of methods.

Methods are used to group related codes together, so that they function as one, after being called/invoked

The printAll() method, where comments are used to explain each line is as follows:

//This defines the printAll() method

public void printAll(){  

//This calls the base class of the printAll() method

  super.printAll();  

//This prints the required output

  System.out.print(idNum);

}

C) Reference

Explanation:

Stream objects are usually passed to functions as parameters, similar to other kind of objects. When passing a stream parameter, it must always be pass-by-reference.

This means that a reference to the original object is being passed to the function and not the copy of the object. As such, the object can be modified within the function. Also, if the object is large or has a large memory, copying it may be inefficient as regards the memory space and the time.

Therefore, object references point to the same object even when they are passed to functions.

c. Service monitoring alerts

Explanation:

Given the fact that system administrators manage so many computer systems,  they are equipped with service monitoring alerts that indicate when there is a problem with any of the systems and the extent or magnanimity of the problem. This is necessary so as to attract responses from the right personnel.

Metrics are deployed to gather raw data on the system's use and behavior. Monitoring compiles these data to useful information that can be stored when they meet up to some standards. The alert system sends out signals to the administrators when some acceptable standards are not met. So, the service, monitoring alerts are used by system admins to organize issues.

Explanation:

Arrays are allowed to store multiple elements of the same data type, all of them stored with the same array hence preventing the need for creating separate variables for each element. An array therefore will act as a container for storing several variables all of the same type. This offers a lot of convinience and enhances better memory space management. In java arrays are declared by:

dataType[] arrayName;

Where dataType is the datatype of elements to be stored in the arrays. This is followed by a pair of square brackets then the name of the array.

for declaration and initialization in Java, the new keyword is used as:

dataType[] arrayName = new dataType[arraySize];

Fix:

void Swap(int &x, int &y){

           int temp;

           temp = x;

           x = y;

           y = temp;        }

See the explanation

Explanation:

1. swap.cpp

//Name: ABC    Date: dd/mm/yyyy

#include

using namespace std;

void Swap(int x,int y); //prototype

int main(){

   int num1, num2;

   cout << "Please enter two numbers to swap, the same numbers will quit." << endl;

   cin >> num1 >> num2;    

   while (num1 != num2) {

       Swap(num1,num2);

       cout << "After swap, the numbers are " << num1 << " " << num2 << endl;

       cout << "Please enter two numbers to swap, ";

       cout << "the same numbers will quit." << endl;

       cin >> num1 >> num2; }

       cout << "Thanks!" << endl;

       return 0; }

//********************//This subroutine swaps two numbers // ********************

       void Swap(int x, int y){

           int temp;

           temp = x;

           x = y;

           y = temp;}

The output of this program with num1 = 1 and num2 = 2 is:

Please enter two numbers to swap, the same numbers will quit.                 1                                                                                                                               2                                                                                                                               After swap, the numbers are 1 2                                                                         Please enter two numbers to swap, the same numbers will quit.                 1                                                                                                                           

1                                                                                                                               Thanks!  

Notice that the numbers 1 and 2 are not swapped correctly even when the Swap() method is called in the main() function.

The other numbers 1 and 1 are entered in order to quit the program.

2.

In this part first output statement a) is added to the start of Swap() method before swapping the numbers x and y and the output statement b) is added to the last after the set of operations performed to swap x and y.

   void Swap(int x, int y){

       cout << " beginning of swap " << x << " " << y << endl;

           int temp;

           temp = x;

           x = y;

           y = temp;

           cout << " end of swap " << x << " " << y << endl;        }

Lets say x = 1 and y = 2

The output of these two statements is:

beginning of swap 1 2      

end of swap 2 1    

This shows that the Swap() function is working correctly and swapping the two numbers x and y.

3.    

The reason that the program is not working properly is that x and y are value parameters. They are like local variables and local to the Swap() function. So changes made to them have no effect on the calling functions arguments num1 and num2. That is why the result remains the same when this function is called in the main().

In these three statements of Swap() method:

int temp = x;

   x = y;      

   y = temp;    

temp is a local variable which is local to this Swap function

Similarly x=y; and y= temp statements make changes only in the local copy and not in the values of num1 and num2 which are passed to this function in main()

So for the above example where num1 = 1 and num2 = 2, the statement

 cout << "After swap, the numbers are " << num1 << " " << num2 << endl;

displays:

After swap, the numbers are 1 2

This means their real values are printed as it is without swapping the values.

4.

The solution is to mark the parameters x and y of the function Swap() as reference parameters in the following way:

void Swap(int &x, int &y)

In this way the memory address of each argument num1 and num2 is passed to the Swap(). The Swap() uses this address to both access and change the values.

So   Swap(num1,num2); function call passes the memory address the actual parameters.

For the reference parameter an ampersand (&) is used before the variables x and y of Swap method. Now any changed made to these variables will effect the calling function arguments num1 and num2. So if x and y are swapped then num1 and num2 are also swapped when this function is called in main().

So change the prototype of Swap function as:

void Swap(int &x,int &y);

Change the function definition as:

void Swap(int &x, int &y){

           int temp;

           temp = x;

           x = y;

           y = temp;        }

Now the program gives the following output:

Please enter two numbers to swap, the same numbers will quit.                                                                                 1                                                                                                                                             2                                                                                                                                             After swap, the numbers are 2 1                                                                                                               Please enter two numbers to swap, the same numbers will quit.                                                                                 1                                                                                                                                        1                                                                                                                                             Thanks!
