AWS (Amazon Web Services) Certification Practice Exam

What are the three main storage classes available in AWS S3?

1. Standard, Intelligent Tiering, One Zone-IA

2. Frequently Accessed, Infrequently Accessed, Intelligent Tiering

3. Standard-IA, Intelligent Tiering, Glacier

4. Standard, Reduced Redundancy, Glacier

The correct answer is: Frequently Accessed, Infrequently Accessed, Intelligent Tiering

The three main storage classes available in AWS S3 that are referenced in the chosen answer are indeed categorized based on the access frequency and the requirements for durability and availability. The correct option encapsulates: - **Frequently Accessed (Standard)**: This storage class is optimized for data that is frequently accessed. It provides high durability, availability, and performance for objects that are regularly retrieved. - **Infrequently Accessed (IA)**: This class is designed for data that is accessed less frequently but requires rapid access when needed. It has lower storage costs but higher retrieval costs, making it cost-effective for data that isn’t accessed as often but must still be readily available. - **Intelligent Tiering**: This is a unique storage class that automatically moves data between two access tiers (frequent and infrequent) based on changing access patterns. This feature helps manage costs optimally without sacrificing performance. These three classes collectively aid in efficient data management in terms of cost and performance, allowing users to make more strategic decisions based on how often they access their data. The other options may contain elements of truth regarding S3 storage classes, but they either lack one of the primary classes necessary to encompass a full understanding of S3's capabilities or combine terms
