In the most recent AWS document, Adobe Flash is not in the list of CloudFront's distribution over HTTP or HTTPS. https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/distribution-overview.html RTMPT, one of RTMP protocol families, can ride over HTTP/HTTPS, so answer D is wrong. The RTMP protocol has multiple variations: 1. RTMP proper, the "plain" protocol which works on top of Transmission Control Protocol (TCP) and uses port number 1935 by default. 4. RTMPT, which is encapsulated within HTTP requests to traverse firewalls. RTMPT is frequently found utilizing cleartext requests on TCP ports 80 and 443 to bypass most corporate traffic filtering. The encapsulated session may carry plain RTMP, RTMPS, or RTMPE packets within. https://en.wikipedia.org/wiki/Real-Time_Messaging_Protocol My take is C. BTW, RTMP is no longer supported by AWS since Dec 31, 2020 https://forums.aws.amazon.com/ann.jspa?annID=7356

I think Answer should be D as we can now stream live audio or video through AWS using the Adobe Flash Media Server that makes uses of Amazon EC2, Amazon CloudFront, and Amazon Route 53 https://aws.amazon.com/blogs/aws/live-streaming-with-amazon-cloudfront-and-adobe-flash-media-server/

C is the correct answer. according to the official guide page 215, "Multimedia content on demand using progressive download and Apple HTTP Live Streaming (HLS). You cannot serve Adobe Flash multimedia content over HTTP or HTTPS, but you can serve it using an Amazon CloudFront RTMP distribution.".

I am not sure if C is correct. Does question 301 about Adobe Flash Media Server contradicts this one?
