AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A company requires a storage solution that allows for on-premises file storage to be extended to the cloud, ensuring data is accessible from both environments and that the cloud storage scales automatically based on demand. Which storage solution should the company implement?
Utilize Amazon S3 buckets with a VPN connection from on-premises for direct access to cloud objects.
Deploy AWS Storage Gateway in File Gateway mode, using Amazon S3 for cloud storage.
Use Amazon EBS with snapshots to Amazon S3 for scaling.
Employ Amazon EFS with AWS Direct Connect for hybrid cloud file storage.
AWS Storage Gateway in File Gateway mode is the correct answer because it seamlessly integrates on-premises file storage with cloud storage provided by Amazon S3. It allows the files stored on-premises to be accessed as objects in S3, supports a range of industry-standard storage protocols, and scales easily to accommodate increasing storage needs without requiring substantial changes to the existing on-premises infrastructure. Amazon EBS is block storage and is not suitable for file storage needs that span on-premises and cloud. Although Amazon EFS is a fully managed file storage service, it does not inherently support on-premises environments without additional services or configurations like AWS Direct Connect. Amazon S3 is an object storage which does not offer native file system interfaces required by many on-premises applications.
