Answer: Deploy Amazon CloudFront for content delivery and caching., Convert video files to optimized formats using Amazon Elastic Transcoder.
The correct combination of solutions includes: A) Deploy Amazon CloudFront for content delivery and caching, and C) Use Amazon Elastic Transcoder to convert the video files to more appropriate formats. CloudFront will help reduce latency and improve the playback experience by caching the video content closer to the users. Elastic Transcoder will convert the large raw video files to formats that are more suitable for streaming on mobile devices, reducing buffering issues. Other options, such as using AWS DataSync or Auto Scaling EC2 instances, either do not directly address the playback and buffering concerns or introduce operational overhead.
