200-301 Question 244
Single answerA network administrator needs to configure secure remote management access to a Cisco switch. Which protocol should the administrator use to ensure encrypted communication?
- A
Telnet
- B
SSH
- C
HTTP
- D
Console access
Show answer and explanation
Correct answer: B
Explanation
SSH is the correct choice for secure remote management because it ensures that all communication between the client and the managed device is encrypted, protecting sensitive data such as login credentials. Other options either lack encryption or are not relevant to remote management access.
- A. Incorrect.
Telnet provides remote access but does not encrypt the communication, making it insecure.
- B. Correct.
SSH (Secure Shell) is a protocol designed for secure remote management by encrypting communication between the client and the device.
- C. Incorrect.
HTTP is used for web-based management but does not provide encryption unless HTTPS is used. Therefore, it is not ideal for secure remote access.
- D. Incorrect.
Console access is a physical connection to the device, not a remote management protocol, and it does not inherently provide encryption.
