AWS Certified SysOps Administrator – Associate (legacy) — Question 572
In AWS Storage Gateway, Gateway-cached volumes allow you to retain ________________.
Answer options
- A. a durable and inexpensive offsite backup that you can recover locally
- B. your primary data locally, and asynchronously back up point-in-time snapshots of this data to Amazon S3
- C. your backup application with online access to virtual tapes
- D. low-latency access to your frequently accessed data
Correct answer: D
Explanation
Gateway-cached volumes store your primary data in Amazon S3 and retain a cache of recently and frequently accessed data locally for low-latency access. This minimizes local storage costs while maintaining high performance for active data. In contrast, Gateway-stored volumes keep the entire primary dataset locally, while Tape Gateway provides virtual tape backup capabilities.
