[amp_mcq option1=”administrator” option2=”web server” option3=”web application” option4=”http E. telnet” correct=”option1″]
The correct answer is E. telnet.
Telnet is a network protocol that allows a user to log in to a remote computer and execute commands on that computer. It is a text-based protocol, which means that all communication between the client and server is in the form of text.
Telnet is often used to manage servers and other network devices. It can also be used to access remote applications, such as web servers.
To use telnet, you need to know the IP address or hostname of the remote computer. You also need to know the username and password for that computer.
Once you have connected to the remote computer, you can use the same commands that you would use on a local computer. For example, you can use the cd command to change directories, the ls command to list files, and the pwd command to print the current working directory.
Telnet is a powerful tool, but it is also insecure. All communication between the client and server is in plain text, which means that anyone who can intercept the traffic can see what you are typing.
For this reason, it is not recommended to use telnet to access sensitive information. If you need to access sensitive information remotely, you should use a more secure protocol, such as SSH.
