A net class exam has two essay questions about Firewalls spreadsheets and ACLs Create rules on a firewall to meet the following requirements:Allow all HTTP traffic to a web server with an IP of 192.168.1.25.Allow all HTTP and HTTPS traffic to a web server with an IP of 192.168.1.25.Allow DNS queries from any source to a computer with an IP of 192.168.1.10.Block DNS zone transfer traffic from any source to any destination.Block all DNS traffic from any source to any destination.Implement implicit deny.How many rules would you create? What protocols would you use? What ports? create a table(similar to the below) to meet the above requirements:Rule# permission(A/R) Protocol Source Destination port

I'm working on a algorithms & data structures project and need a reference to help me learn.The language used for this project is C++Also I thank anyone attempting this, this is the reality of inexperienced professors that put us students through so much. Please help me if you can. Thank you so much, very much appreciated.you will develop algorithms that find road routes through the bridges to travel between islands.The input is a text file containing data about the given map. Each file begins with the number of rows and columns in the map considered as maximum latitudes and maximum longitudes respectively on the map. The character "X" in the file represents the water that means if a cell contains "X" then the traveler is not allowed to occupy that cell as this car is not drivable on water. The character "0" in the file represents the road connected island. That means if a cell contains "0" then the traveler is allowed to occupy that cell as this car can drive on roads. The traveler starts at the island located at latitude = 0 and longitude = 0 (i.e., (0,0)) in the upper left corner, and the goal is to drive to the island located at (MaxLattitude-1, MaxLongitudes-1) in the lower right corner. A legal move from an island is to move left, right, up, or down to an immediately adjacent cell that has road connectivity which means a cell that contains "0". Moving off any edge of the map is not allowed.Print paths as explicitly specified for all the functions in Part A, Part B, and extra credit on the console. Input: The map filesOutput: Print paths as explicitly specified for all the functions in Part A, Part B, and extra credit on the console. Part AConsider the following class map,class map{public:map(ifstream &fin);void print(int,int,int,int);bool isLegal(int i, int j);void setMap(int i, int j, int n);int getMap(int i, int j) const;int getReverseMapI(int n) const;int getReverseMapJ(int n) const;void mapToGraph(graph &g);bool findPathRecursive(graph &g, stack<int> &moves);bool findPathNonRecursive1(graph &g, stack<int> &moves);bool findPathNonRecursive2(graph &g, queue<int> &moves);bool findShortestPath1(graph &g, stack<int> &bestMoves);bool findShortestPath2(graph &, vector<int> &bestMoves);void map::printPath(stack<int> &s);int numRows(){return rows;};int numCols(){return cols;};private:int rows; // number of latitudes/rows in the mapint cols; // number of longitudes/columns in the mapmatrix<bool> value;matrix<int> mapping; // Mapping from latitude and longitude co-ordinates (i,j) values to node index valuesvector<int> reverseMapI; // Mapping from node index values to map latitude i valuevector<int> reverseMapJ; // Mapping from node index values to map longitude j value};1. Using the above class map, write function void map::mapToGraph(graph &g){...} to createe a graph g that represents the legal moves in the map m. Each vertex should represent a cell, and each edge should represent a legal move between adjacent cells.2. Writee a recursive function findPathRecursive(graph &g, stack<int> &moves) that looks for a path from the start island to the destination island. If a path from the start to the destination exists, your function should call the map::printPath() function that should print a sequence of correct moves (Go left, Go right, Go down, Go up, etc.). If no path from the start to the destination exists, the program should print, "No path exists". If a solution exists the solver should also simulate the solution to each map by calling the map::print() function. Hint: consider recursive-DFS.3. Writee a function findPathNonRecursive1(graph &g, stack<int> &moves) that does the same thing as in 2, but by using stack and without using recursion. If a path from the start to the destination exists, your function should call the map::printPath() function that should print a sequence of correct moves (Go left, Go right, Go down, Go up, etc.). If no path from the start to the destination exists, the program should print, "No path exists". If a solution exists the solver should also simulate the solution to each map by calling the map::print() function. Hint: consider stack-based DFS.4. Writee a function findPathNonRecursive2(graph &g, queue<int> &moves) that does the same thing as in 2, but by using queue and without using recursion. If a path from the start to the destination exists, your function should call the map::printPath() function that should print a sequence of correct moves (Go left, Go right, Go down, Go up, etc.). If no path from the start to the destination exists, the program should print, "No path exists". If a solution exists the solver should also simulate the solution to each map by calling the map::print() function. Hint: consider queue-based BFS.Part BThe shortest path on a map is a path from the start to the destination with the smallest number of intermediate islands, that is the path with the least number of intermediate "0".1. Write two functions findShortestPath1(graph &g, stack<int> &bestMoves) and findShortestPath2(graph &g, stack<int> &bestMoves) that each finds the shortest path on a map if a path from the start to the destination exists. The first algorithm should use Dijkstra algorithm and the second algorithm should use Bellman-Ford algorithm to find the shortest paths. In each case, if a solution exists the solver should call the map::printPath() function that should print a sequence of correct moves (Go left, Go right, Go down, Go up, etc.). If no path from the start to the destination exists, the program should print, "No path exists". If a solution exists the solver should also simulate the solution to each map by calling the map::print() function. Each function should return true if any paths are found, and false otherwise..pdf file | C++-
