A network administrator needs to establish a remote command-line session to configure a network router. Which remote access protocol should the administrator select to ensure that all session data, including login credentials, is encrypted?

  1. A
    Telnet
  2. Secure Shell (SSH)Cevap
  3. C
    Remote Desktop Protocol (RDP)
  4. D
    Virtual Network Computing (VNC)

Cevap

Secure Shell (SSH)
Secure Shell (SSH) encrypts all command-line communication, including login credentials and commands, preventing unauthorized interception during remote network administration.

Adım Adım Çözüm

1
Identify the primary requirement from the scenario: encrypted remote command-line access to a router.
The solution must support a text-based interface and enforce end-to-end encryption for authentication and commands.
Transmitting management credentials in clear text over a network creates severe security risks.
2
Compare available remote access protocols against interface and security requirements.
SSH provides secure, encrypted CLI access over TCP port 22. Telnet provides unencrypted CLI access, while RDP and VNC provide graphical interfaces.
SSH is the standard secure protocol for remote command-line device administration.
