AWS Certified Alexa Skill Builder – Specialty — Question 30

An Alexa Skill Builder is using Amazon S3 to stream large quantities of static audio and video content throughout the world with an Amazon Alexa skill.
Which additional AWS service will help the Builder decrease latency and improve the reliability of the streaming media content for the global audience?

Answer options

Correct answer: D

Explanation

The correct answer is D, Amazon CloudFront, as it is a content delivery network (CDN) that caches content at edge locations, reducing latency and improving streaming performance. The other options, such as AWS Cloud9, are primarily development environments, Amazon Kinesis is focused on real-time data processing, and Amazon Route 53 is for DNS management, none of which specifically enhance media streaming efficiency.
