Single answerA network administrator is tasked with configuring secure remote management access to a router. The administrator wants to ensure that data between the management device and the router is encrypted. Which method should the administrator use?
- A
Telnet
- B
SSH
- C
HTTP
- D
Console
Show answer and explanation
Correct answer: B
Explanation
To securely manage a router remotely and protect sensitive data like login credentials, the administrator should use SSH. Unlike Telnet, HTTP, or console connections, SSH provides encryption for all transmitted data, ensuring the communication is secure.
- A. Incorrect.
Telnet transmits data, including login credentials, in plain text, which makes it insecure for remote management.
- B. Correct.
SSH (Secure Shell) encrypts all data transmitted between the management device and the router, ensuring secure remote management access.
- C. Incorrect.
HTTP is used for web-based management but does not encrypt data, making it less secure compared to HTTPS.
- D. Incorrect.
The console connection is a direct physical connection to the device and does not provide remote access capabilities.
