SSH

A network technician has provisioned a new Linux instance in a public cloud provider's IaaS environment.

The technician did not install a graphical user interface.

The technician wants to connect to the server's public IP address securely to start a console session.

Which of the following remote access methods should the technician use?

A.

SSH

B.

Telnet

C.

VNC

D.

RDP.

A.

The remote access method that the technician should use to securely connect to the Linux instance without a graphical user interface is SSH (Secure Shell).

SSH is a network protocol that provides a secure way to access a remote computer. It encrypts the communication between the client and the server, which prevents eavesdropping and tampering with the data being transmitted.

In this scenario, the technician wants to connect to the server's public IP address securely to start a console session. SSH allows the technician to establish a secure command-line connection to the Linux instance using the public IP address. The technician can then use the command line interface to manage the Linux instance without the need for a graphical user interface.

The other remote access methods listed in the options are not secure or not suitable for this scenario:

• Telnet is not secure, as it transmits data in plain text and can be easily intercepted.
• VNC (Virtual Network Computing) is a graphical desktop sharing system that allows remote access to a desktop environment. However, it requires a graphical user interface to be installed on the server, which is not the case in this scenario.
• RDP (Remote Desktop Protocol) is a proprietary protocol developed by Microsoft for remote access to Windows-based systems. It is not suitable for accessing a Linux instance, which is the case in this scenario.
