Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
You have the choice of using SSH or telnet to remote manage a machine, what would you choose?
A
telnet as the commands are built into all operating systems
B
SSH as it provides encryption of the commands being sent and recieved
C
telnet as it provided encryption of the commands being sent and received
D
SSH as all systems have it installed so its there to use
Explanation: 

Detailed explanation-1: -Secure Shell or SSH is a secure protocol and the replacement for Telnet and other insecure remote shell protocols. So for secure communication between network devices, I strongly recommend using SSH instead of Telnet.

Detailed explanation-2: -SSH can be used interactively to enable terminal sessions and should be used instead of the less secure Telnet program. SSH is also commonly used in scripts and other software to enable programs and systems to remotely and securely access data and other resources.

Detailed explanation-3: -SSH serves the same primary function as Telnet but does so in a more secure way. This protocol provides secure access even on unsecured networks, eliminating many of Telnet’s vulnerabilities. With SSH, administrators can log into remote devices, execute commands, move files between devices, and more.

Detailed explanation-4: -SSH is a more secure protocol, so it uses public-key encryption for authentication. Telnet transfers the data in plain text. The encrypted format should be used to send data and also uses a secure channel. Telnet is vulnerable to security attacks.
