CompTIA Cloud+ Practice Test

Which of the following remote access protocols is commonly used to manage servers in the cloud?

1. HTTP

2. FTP

3. SSH

4. Telnet

The correct answer is: SSH

SSH, or Secure Shell, is widely used for managing servers remotely in cloud environments due to its strong security features. It provides a secure channel over an unsecured network by utilizing encryption, ensuring that data exchanged during the session is protected from eavesdropping and tampering. This security is particularly important in cloud computing, where servers may be distributed across various geographic locations and may be accessed over the public internet. SSH not only authenticates users but also encrypts all communications between the client and the server, making it the preferred method for system administrators who need to perform operations, transfer files securely, and manage configurations safely. In contrast, other protocols like HTTP and FTP do not provide the necessary security for managing sensitive server operations. HTTP is primarily used for web traffic without secure channels, and while FTP is used for transferring files, it does so in an unencrypted format, which can expose data. Telnet is an older protocol that also lacks encryption, making it insecure for remote management, as transmitted data, including passwords, can be easily intercepted. Thus, SSH stands out as the most suitable and secure choice for managing cloud servers.
