An application downloads large video files from Amazon S3. Users often skip to the middle of a video. To improve performance and reduce data transfer, the application should only download the specific portion of the file being requested. How can this be achieved?

Answer options:

Use S3 Select.

Use S3 Multipart Download.

Use S3 Byte-Range Fetches.

Use Amazon CloudFront with media streaming enabled.

How to approach this question

Identify the HTTP feature supported by S3 to download partial files.

Full Answer

C.Use S3 Byte-Range Fetches.✓ Correct

Using the HTTP Range header in a GET request, you can download a specific range of bytes from an object stored in Amazon S3. This is known as a Byte-Range Fetch and is ideal for video streaming.

Common mistakes

Confusing S3 Select (data filtering) with Byte-Range Fetches (binary file chunking).
