200-301 Question 394
Single answerA network administrator is configuring a Cisco router to back up its configuration file to a central server. The administrator wants to use a protocol that is lightweight, does not require authentication, and operates over UDP. Which protocol should the administrator choose?
- A
TFTP
- B
FTP
- C
SFTP
- D
HTTP
Show answer and explanation
Correct answer: A
Explanation
The administrator should use TFTP because it is simple, lightweight, operates over UDP, and does not require authentication, making it ideal for quick file transfers such as configuration backups in network devices.
- A. Correct.
TFTP (Trivial File Transfer Protocol) is a lightweight protocol that operates over UDP, does not require authentication, and is often used for transferring configuration files and boot images in network environments.
- B. Incorrect.
FTP (File Transfer Protocol) is a more robust protocol that operates over TCP and provides authentication. It is not as lightweight as TFTP and is not typically used for scenarios that require simplicity.
- C. Incorrect.
SFTP (SSH File Transfer Protocol) is a secure protocol that operates over SSH. It includes encryption and authentication, making it more complex and resource-intensive than TFTP.
- D. Incorrect.
HTTP is primarily used for transferring web content rather than configuration files or backups in network environments. It is not relevant to this scenario.
