AWS Certified Cloud Practitioner (CLF-C02) — Question 492

A company needs to convert video files and audio files to a format that will play on smartphones.

Which AWS service will meet this requirement?

Answer options

• A. Amazon Comprehend
• B. Amazon Rekognition
• C. Amazon Elastic Transcoder
• D. Amazon Polly

Correct answer: C

Explanation

Amazon Elastic Transcoder is a cloud-based media transcoding service designed to convert video and audio files into formats that can play on smartphones, tablets, and PCs. Amazon Comprehend is a natural language processing service, Amazon Rekognition is for image and video analysis, and Amazon Polly converts text to speech, making them unsuitable for media format conversion.
