Question 56 of 100 | ← Chapter 1

A company stores petabytes of data in thousands of Amazon S3 buckets in the S3 Standard storage class. The data supports analytics Workloads that have unpredictable and variable data access patterns. The company does not access some data for months. However, the company must be able to retrieve all data within milliseconds. The Company needs to optimize S3 storage costs. Which solution will meet these requirements with the LEAST operational overhead?

• A. Use S3 Storage Lens standard metrics to determine when to move objects to more cost-optimized storage classes. Create S3 Lifecycle policies for the S3 buckets to move objects to cost-optimized storage classes. Continue to refine the S3 Lifecycle policies in the future to optimize storage costs.
• B. Use S3 Storage Lens activity metrics to identify S3 buckets that the company accesses infrequently. Configure S3 Lifecycle rules to move objects from S3 Standard to the S3 Standard-Infrequent Access (S3 Standard-IA) and S3 Glacier storage classes based on the age of the data.
• C. Use S3 Intelligent-Tiering. Activate the Deep Archive Access tier.
• D. Use S3 Intelligent-Tiering. Use the default access tier. ✓

Correct Answer: D. Use S3 Intelligent-Tiering. Use the default access tier.

Explanation

考虑到公司需要优化S3存储成本，同时必须能够在毫秒内检索所有数据，S3Intelligent-Tiering的默认访问层级是一个合适的解决方案。S3Intelligent-Tiering可以自动将数据移动到最经济的存储层级，而无需牺牲性能或检索速度，因为它保证了所有层级的毫秒级访问。因此，选项D既满足了成本优化的需求，又满足了数据快速检索的要求，且运营开销最小。
