nmap Task 2 What networking constructs are used to direct traffic to the right application on a server? ports How many of these are available on any network-enabled computer? 65535 [Research] How many of these are considered “well-known”? (These are the “standard” numbers mentioned in the task)? 1024 Task 3 What is the first switch listed in the help menu for a ‘Syn Scan’ (more on this later!)? -sS Which switch would you use for a “UDP scan”? -sU If you wanted to detect which operating system the target is running on, which switch would you use? -O Nmap provides a switch to detect the version of the services running on the target. What is this switch? -sV The default output provided by nmap often does not provide enough information for a pentester. How would you increase the verbosity? -v Verbosity level one is good, but verbosity level two is better! How would you set the verbosity level to two? (Note: it’s highly advisable to a

python 4-1. Pizzas: Think of at least three kinds of your favorite pizza. Store these pizza names in a list, and then use a for loop to print the name of each pizza.Modify your for loop to print a sentence using the name of the pizza instead of printing just the name of the pizza. For each pizza you should have one line of output containing a simple statement like I like pepperoni pizza. Add a line at the end of your program, outside the for loop,that states how much you like pizza. The output should consist of three or more lines about the kinds of pizza you like and then an additional sentence, such as I really love pizza! 4-2. Animals: Think of at least three different animals that have a common characteristic. Store the names of these animals in a list, and then use a for loop to print out the name of each animal. Modify your program to print a statement about each animal,such as A dog would make a great pet. Add a line at the end of your program stati
