Question 58 of 100 | ← Chapter 13

Q958. A company stores user data in AWS.The data is used continuously with peak usage during business hours.Access patterns vary, with some data not being used for months at a time.A solutions architect must choose a cost-effective solution that maintains the highest level of durability while maintaining high availability.Which storage solution meets these requirements?

Correct Answer: B. Amazon S3 Intelligent-Tiering

Explanation

The storage solution that meets these requirements is B. Amazon S3 Intelligent-Tiering.Here's why:Cost-Effective: Intelligent-Tiering automatically transitions data between access tiers (Frequent Access, Infrequent Access, and Archive Access) based on access patterns. This optimizes storage costs by placing frequently accessed data in the most cost-effective tier.High Durability: S3 Intelligent-Tiering offers the same high durability as other S3 storage classes (99.999999999% durability).High Availability: S3 is a highly available service, ensuring that data is accessible even during peak usage periods.Variable Access Patterns: Intelligent-Tiering is ideal for data with variable access patterns, as it automatically adjusts storage tiers based on usage, reducing storage costs for data that is accessed infrequently.Why other options are less suitable:A. Amazon S3 Standard: While S3 Standard offers high durability and availability, it's the most expensive storage class. It's not cost-effective for data with infrequent access patterns. C. Amazon S3 Glacier Deep Archive: Glacier Deep Archive is designed for long-term archival data that is rarely accessed. It's not suitable for data that is used continuously, even if access patterns vary. D. Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA): One Zone-IA is a lower-cost storage class, but it only offers a single-zone availability. This might not be suitable for data that requires high availability, especially during peak usage periods.In summary:S3 Intelligent-Tiering provides a cost-effective solution for storing user data with variable access patterns while maintaining high durability and availability. It automatically optimizes storage costs based on usage, ensuring that the company pays only for the storage it needs.
