Which service is commonly used for secure remote command access to RouterOS?

• A. Telnet
• B. SSH
• C. FTP
• D. VNC

Answer: (B)

Accessing RouterOS remotely for command-line management requires a protocol that protects the session from eavesdropping and tampering. SSH provides encrypted, authenticated remote shell access, making it the standard choice for secure administration. When you connect with SSH, credentials and all commands are encrypted, so someone monitoring the network can’t see them. In RouterOS, SSH is used to access the CLI securely, and you can even use key-based authentication for stronger security. Telnet sends everything in plaintext, so passwords and commands can be intercepted. FTP is designed for file transfers, not interactive command access, and VNC is for remote desktop sessions rather than a secure command line. So the best choice for secure remote command access is SSH.
