300-410 Question 254
Select 3You are configuring secure remote access for network administrators to manage routers in your enterprise network. The security policy mandates encrypted communication and prohibits clear-text protocols for management and file transfers. Which protocols should you implement to meet this requirement?
- A
Telnet
- B
SSH
- C
HTTP
- D
HTTPS
- E
SCP
Show answer and explanation
Correct answers: B, D, E
Explanation
To meet the requirement for encrypted communication and avoid clear-text protocols, you should implement SSH for secure remote access, HTTPS for secure web-based management, and SCP for secure file transfers. Telnet and HTTP transmit data in plain text, making them unsuitable for secure environments.
- A. Incorrect.
Telnet transmits data, including login credentials, in plain text, making it insecure for remote access. It does not meet the requirement for encrypted communication.
- B. Correct.
SSH (Secure Shell) provides encrypted communication for secure remote management, making it suitable for the security policy.
- C. Incorrect.
HTTP is a clear-text protocol and does not offer encrypted communication, making it unsuitable for secure management.
- D. Correct.
HTTPS (Hypertext Transfer Protocol Secure) provides encrypted communication for web-based management interfaces, meeting the security policy's encryption requirement.
- E. Correct.
SCP (Secure Copy Protocol) uses SSH to securely transfer files, ensuring encrypted communication, which aligns with the security policy.
