Explanation
This question asks to identify supported protocols for software image delivery from a remote server, with a specific focus on HTTP as the provided correct answer.
Common mistakes.
- A. TFTP (Trivial File Transfer Protocol) is not typically used or recommended for production software image delivery in SD-WAN due to its lack of security, authentication, and reliability features.
- B. SSL (Secure Sockets Layer) is a security protocol that provides encryption but is not an application-layer file transfer protocol itself; it's used by protocols like HTTPS.
- C. HTTPS (Hypertext Transfer Protocol Secure) is a secure protocol for image delivery, but it is not listed as the sole correct answer, implying it is not the intended primary answer when only D is given.
- E. FTP (File Transfer Protocol) is a file transfer protocol, but in the context of the provided single correct answer 'D', it is not the chosen option for this question, despite being technically possible in some SD-WAN contexts.
