300-410 Question 257
Single answerA network engineer is tasked with securely transferring a configuration file from a local workstation to a Cisco router. The engineer needs to use a method that ensures encryption during transmission. Which protocol should the engineer use?
- A
Telnet
- B
HTTP
- C
SCP
- D
SSH
Show answer and explanation
Correct answer: C
Explanation
SCP (Secure Copy Protocol) is the correct choice for securely transferring files, as it uses SSH for encryption, ensuring data confidentiality during transmission. Other protocols like Telnet and HTTP do not provide encryption, while SSH is more suited for remote access rather than file transfer.
- A. Incorrect.
Telnet is an unencrypted protocol and does not provide secure data transmission. It is not suitable for transferring sensitive files.
- B. Incorrect.
HTTP is an unencrypted protocol used for web communication. It does not ensure secure file transfer.
- C. Correct.
SCP (Secure Copy Protocol) is designed for securely transferring files between devices. It uses SSH for encryption, ensuring secure transmission.
- D. Incorrect.
SSH is a secure protocol for remote device access but is not primarily intended for file transfers. While SSH provides encryption, SCP is more appropriate for this task.
