Q171.解决方案架构师需要实施解决方案来降低公司的存储成本.公司的所有数据都在 Amazon S3 标准存储类中.公司必须将所有数据保存至少 25 年.最近 2 年的数据必须高度可用且可立即检索.哪种解决方案可以满足这些要求?

正确答案: B. 设置 S3 生命周期策略以在 2 年后将对象转换到 S3 Glacier Deep Archive.

解析

Option A suggests setting up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive immediately, which would not meet the requirement of keeping the most recent 2 years' data highly available and immediately retrievable.Option C suggests using S3 Intelligent-Tiering and activating the archiving option to ensure that data is archived in S3 Glacier Deep Archive. While this approach could work, it may not provide the same level of cost savings as directly transitioning objects after 2 years, and it requires more configuration management.Option D suggests setting up an S3 Lifecycle policy to transition objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) immediately and to S3 Glacier Deep Archive after 2 years. This approach could work but would not provide the same level of cost savings as directly transitioning objects to Glacier Deep Archive after 2 years.Setting up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 2 years provides a cost-effective solution for managing data that is rarely accessed. The most recent 2 years' data is kept in the S3 Standard storage class, providing immediate retrieval when needed. Once the data becomes older than 2 years, an S3 Lifecycle policy can be configured to automatically transition the objects to the Glacier Deep Archive storage class, which provides the lowest storage costs. This approach meets the storage cost reduction requirement while maintaining the ability to quickly access the most recent data.选项A建议设置一个S3生命周期策略，将对象立即转换到S3 Glacier Deep Archive，这将不满足保持最近2年的数据高度可用和立即可检索的要求。选项C建议使用S3智能分层和激活存档选项，以确保数据存档在S3冰川深度存档。虽然这种方法可以工作，但它可能无法在2年后提供与直接转换对象相同的成本节约水平，并且它需要更多的配置管理。选项D建议设置S3生命周期策略，将对象立即转换为S3 One zone - infrequency Access (S3 One Zone-IA)，并在2年后转换为S3 Glacier Deep Archive。这种方法可以工作，但不能提供与2年后直接将对象转换到Glacier Deep Archive相同的成本节约水平。设置S3生命周期策略，在2年后将对象转换到S3 Glacier Deep Archive，为管理很少访问的数据提供了一个经济有效的解决方案。最近2年的数据保存在S3 Standard存储类中，在需要时提供即时检索。一旦数据超过2年，可以配置S3生命周期策略，自动将对象转换到Glacier Deep Archive存储类，该存储类提供最低的存储成本。这种方法在保持快速访问最新数据的能力的同时满足了存储成本降低的要求。
