AWS Certified SysOps Administrator – Associate (legacy) — Question 533

A company's Marketing department generates gigabytes of assets each day and stores them locally. They would like to protect the files by backing them up to
AWS. All the assets should be stored on the cloud, but the most recent assets should be available locally for low latency access.
Which AWS service meets the requirements?

Answer options

• A. Amazon EBS
• B. Amazon EFS
• C. Amazon S3
• D. AWS Storage Gateway

Correct answer: D

Explanation

AWS Storage Gateway provides a hybrid cloud storage service that allows on-premises applications to seamlessly use AWS cloud storage while caching frequently accessed data locally for low-latency access. Amazon EBS and Amazon EFS are designed for cloud-based EC2 instances and do not natively support local caching for on-premises environments. While Amazon S3 stores the data in the cloud, it requires AWS Storage Gateway to act as the bridge that maintains the local cache.
