AWS Certified Data Analytics Specialty 2021 – Hands-On - S3 Storage Classes Hands-On

The video tutorial provides an in-depth look at Amazon S3 storage classes, demonstrating how to create a bucket, upload objects, and explore various storage class options. It covers the features and conditions of each class, including Standard, Intelligent Tiering, and Glacier options. The tutorial also explains how to change storage classes for objects and automate transitions using lifecycle rules, offering a comprehensive guide to managing data storage efficiently in AWS.

Which S3 storage class is best suited for data that is infrequently accessed but requires low latency?

• Intelligent Tiering

• Standard-IA

• Standard

• One Zone-IA

What is the purpose of Intelligent Tiering in S3 storage classes?

• To ensure data is always stored in the Standard class

• To provide the fastest retrieval time

• To automatically move data to the most cost-effective access tier

• To store data in a single AZ

What is a key risk associated with using the One Zone-IA storage class?

• Data loss if the AZ is destroyed

• Higher cost compared to Standard

• Data is stored in multiple AZs

• Automatic data tiering

Which Glacier storage class offers the fastest retrieval time?

• Standard-IA

• Glacier Deep Archive

• Glacier Flexible Retrieval

• Glacier Instant Retrieval

How can you automate the transition of objects between different S3 storage classes?

• Using lifecycle rules

• By manually changing the storage class

• Through the AWS CLI only

• By setting up a cron job
