Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 226

A network engineer must download a firmware image from a remote location to a Cisco UCS Fabric Interconnect. The software bundle is over 232 MB in size. The file transfer must use encryption and authentication. Which protocol must be used to accomplish this goal?

Answer options

• A. TFTP
• B. SCP
• C. RDP
• D. HTTPS

Correct answer: B

Explanation

SCP (Secure Copy Protocol) is designed for secure file transfers over SSH, providing both encryption and authentication, making it suitable for transferring sensitive firmware images. In contrast, TFTP (Trivial File Transfer Protocol) lacks encryption and authentication, RDP (Remote Desktop Protocol) is used for remote desktop connections, and HTTPS (HyperText Transfer Protocol Secure) is primarily for secure web traffic rather than direct file transfers.
