Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 293 discussion

The question states, "wants to maintain local access to all the data" This is storage gateway. Cached gateway stores only the frequently accessed data locally which is not what the problem statement asks for.

1. The company wants to maintain local access to all the data. Only stored volumes keep the complete dataset on-premises, providing low-latency access. Cached volumes only cache a subset locally. 2. The company wants the data backed up on AWS. With stored volumes, periodic backups (snapshots) of the on-premises data are sent to S3, providing durable and scalable backup storage. 3. The company wants the data transfer to AWS to be automatic and secure. Storage Gateway provides an encrypted connection between the on-premises gateway and AWS storage. Backups to S3 are sent asynchronously and automatically based on the backup schedule configured.

The Volume Gateway runs in either a cached or stored mode. In the cached mode, your primary data is written to S3, while retaining your frequently accessed data locally in a cache for low-latency access. In the stored mode, your primary data is stored locally and your entire dataset is available for low-latency access while asynchronously backed up to AWS. https://aws.amazon.com/storagegateway/faqs/#:~:text=What%20is%20Volume%20Gateway%3F
