Correct answer: HTTPS, HTTP.
Why this is the answer
Cisco SD-WAN devices support HTTP and HTTPS for downloading software images from a remote server. These protocols are widely used for web-based data transfer and offer flexibility for image distribution. HTTPS is preferred due to its encryption, providing secure image downloads and ensuring integrity. HTTP is also supported for environments where security is less critical or for legacy systems. TFTP is typically used for small file transfers like configuration files or initial boot images, not large software images. FTP is an older protocol that is less commonly used for this purpose in modern network devices due to security concerns and the prevalence of HTTP/S. SSL is a security protocol that underlies HTTPS, not a standalone transfer protocol for this context.
