Question 2: Reachability and Availability                                     

This task uses the tracert command to find the router level path from your computer to a remote Internet host. The tracert command is a standard command-line utility for discovering the Internet paths that your computer uses. It is widely used for network troubleshooting. It comes pre-installed on Window and Mac, and can be installed using your package manager on Linux. On Windows, it is called “tracert”.

To write tracert output to a file, on the command prompt type: tracert en.wikipedia.org > documents\mytracert.txt and press Enter. The mytracert.txt file is to be created and ‘documents’ simply refers to the folder where the file will be saved. You can direct the output to any file of your choice by specifying correct path.

 Now, inspect your tracert output and use it to answer the following questions:
