Question 4
A company wants to create a mobile app that allows users to stream slow-motion video clips on their mobile devices. Currently, the app captures video clips and uploads the video clips in raw format into an Amazon S3 bucket. The app retrieves these video clips directly from the S3 bucket. However, the videos are large in their raw format. Users are experiencing issues with buffering and playback on mobile devices. The company wants to implement solutions to maximize the performance and scalability of the app while minimizing operational overhead. Which combination of solutions will meet these requirements? (Choose two.)
- A Deploy an Auto Scaling group of Amazon EC2 instances to convert the video files to more appropriate formats.
- B Use AWS DataSync to replicate the video files across AW'S Regions in other S3 buckets.
- C Use Amazon Elastic Transcoder to convert the video files to more appropriate formats.
- D Deploy Amazon CloudFront for content delivery and caching.
- E Deploy an Auto Sealing group of Amazon EC2 instances in Local Zones for content delivery and caching.
Reveal correct answers
Correct answer: D
Explanation
To address the issues of buffering and playback on mobile devices while maximizing performance and scalability, the company should implement the following solutions: 1. **Deploy Amazon CloudFront for content delivery and caching**: This will help in delivering the video content more efficiently by caching it at edge locations closer to the users, reducing latency and improving playback performance. 2. **Use Amazon Elastic Transcoder to convert the video files to more appropriate formats**: This will reduce the size of the video files, making them more suitable for streaming on mobile devices, thereby minimizing buffering issues. These solutions will enhance the app's performance and scalability while minimizing operational overhead.Discussion
