Explanation
Correct answer: B) SSH (Secure Shell).
SSH (Secure Shell) is a protocol used to securely access and manage remote devices over a network. It encrypts the communication between the client and the server, ensuring secure access for troubleshooting, managing, or configuring devices remotely. SSH is widely used for secure remote administration, especially for servers and network devices.
Here’s why the other options are not suitable for securely accessing a remote network for troubleshooting:
-
FTP (File Transfer Protocol): FTP is used for transferring files over a network but does not provide encryption or secure access, making it unsuitable for secure troubleshooting.
-
RDP (Remote Desktop Protocol): RDP is a Microsoft protocol used to remotely control Windows desktops and servers. While it allows for remote troubleshooting, it is not as universally applicable as SSH and is typically used for GUI-based remote desktop access rather than network device management.
-
TFTP (Trivial File Transfer Protocol): TFTP is a simple file transfer protocol used for transferring files between devices, but it does not provide security or encryption, making it unsuitable for secure troubleshooting.
