CLF-C02 Question 234
Single answerA company wants to enable a hybrid cloud storage solution where frequently accessed files are cached locally for low-latency access, while the full dataset is stored securely in the cloud. Which AWS service can be used to achieve this?
- A
AWS Storage Gateway File Gateway
- B
Amazon Elastic File System (EFS)
- C
Amazon S3 Glacier
- D
AWS Backup
Show answer and explanation
Correct answer: A
Explanation
AWS Storage Gateway File Gateway is the appropriate solution for hybrid cloud storage scenarios where local caching is required. It allows on-premises applications to access a subset of data with low latency while the full dataset resides in Amazon S3, providing both cost-efficiency and performance.
- A. Correct.
AWS Storage Gateway File Gateway is designed to enable hybrid cloud storage by caching frequently accessed data locally, while keeping the full dataset in Amazon S3. This makes it the correct service for the described scenario.
- B. Incorrect.
Amazon Elastic File System (EFS) is a fully managed network file system for cloud-based workloads. It is not designed for hybrid environments or caching on-premises data locally.
- C. Incorrect.
Amazon S3 Glacier is a low-cost storage solution for archiving and long-term backup. It is not suitable for hybrid cloud storage or local caching.
- D. Incorrect.
AWS Backup is used for centralizing and automating backups across AWS services but does not provide hybrid storage or local caching capabilities.
