AWS Certified Solutions Architect Associate SAA-C03 Practice Question
Your application requires a managed storage solution to serve large media files to users globally with low latency. The files are accessed frequently and need to be updated in a write-once-read-many model. Which storage service is BEST suited to meet these requirements?
Amazon Elastic File System (EFS), because of its file-based storage that can scale automatically to petabytes of data
Amazon Glacier, for long-term archival of data accessed infrequently
Amazon S3, due to its global reach, durability, and integration with content delivery networks
Amazon Elastic Block Store (EBS), due to its block storage capabilities suitable for high-performance workloads
Amazon Simple Storage Service (Amazon S3) is the most appropriate storage service for serving large media files globally with low latency. As an object storage service, it is designed to store and retrieve any amount of data from anywhere. S3 is well-suited for the write-once-read-many access model, which matches the requirement of updating files infrequently and serving them frequently. Moreover, when combined with Amazon CloudFront for content distribution, it can deliver media files with low latency to users worldwide due to CloudFront's edge locations.
