When using AWS EC2, how is the virtual machine accessed after launching it?

• A. Through a web browser
• B. Using a command prompt only
• C. With remote desktop access
• D. Via an FTP client

Answer: (C)

Accessing a virtual machine (VM) on AWS Elastic Compute Cloud (EC2) typically involves employing remote desktop protocols, especially when working with Windows instances. This method allows users to interact with the graphical user interface of the virtual machine as if they were sitting in front of it.

For Windows instances, Remote Desktop Protocol (RDP) is used, which provides secure remote access and a familiar desktop experience that users can navigate through graphical inputs. For Linux instances, Secure Shell (SSH) is commonly utilized to access the virtual machine's terminal interface, allowing for command-line operations.

In cloud environments like AWS, flexibility in accessing the instances is crucial for configuration, management, and troubleshooting, making remote access a standard approach. While web browsers, command prompts, and FTP clients serve specific purposes and might be used in certain scenarios, they are not the primary means of gaining comprehensive access to a VM in the way that remote desktop access enables.
