- B
SSH

- D
HTTPS
Show answer and explanation
Correct answer: B
Explanation
SSH is the most secure protocol for remotely managing network devices because it encrypts all transmitted data, including sensitive information like login credentials. Other options, such as Telnet and HTTP, are insecure as they transmit data in plain text, and HTTPS is not commonly used for device management.
- A. Incorrect.
Telnet transmits data, including login credentials, in plain text, making it insecure for remote management.
- B. Correct.
SSH (Secure Shell) encrypts all transmitted data, including login credentials, making it a secure choice for remote device management.
- C. Incorrect.
HTTP is primarily used for accessing web pages and transmits data in plain text, making it unsuitable for secure network device management.
- D. Incorrect.
HTTPS is used for secure communication over the web but is not typically used for managing network devices remotely.
