AWS Certified Data Analytics Specialty 2021 - Hands-On! - Amazon Simple Storage Service (Amazon S3) Lifecycle Rules

The video tutorial covers AWS storage classes and lifecycle configurations, explaining how to transition objects between classes like Standard IA, Glacier, and Deep Archive. It discusses lifecycle rules for transitioning and expiring objects, and provides scenarios for designing cost-effective storage solutions. The first scenario involves storing images and thumbnails, while the second focuses on recovering deleted objects. Key concepts include storage class transitions, lifecycle configurations, and cost-effective storage solutions.

What is the primary purpose of using lifecycle configurations in AWS S3?

• To increase the storage capacity of S3 buckets

• To automate the transition of objects between storage classes

• To manually move objects between storage classes

• To enhance the security of stored objects

Which action can be defined in a lifecycle rule to manage object storage?

• Reducing object redundancy

• Increasing object size

• Transitioning objects to a different storage class

• Encrypting objects

How can you manage old versions of files in S3 with lifecycle rules?

• By enabling cross-region replication

• By disabling versioning

• By setting expiration actions for old versions

• By increasing the storage class tier

In the given scenario, where should the source images be stored after 45 days?

• In the Deep Archive storage class

• In the Standard storage class

• In the One Zone-IA storage class

• In the Glacier storage class

What is the recommended storage class for thumbnails that can be easily recreated?

• Intelligent-Tiering

• Glacier

• Standard

• One Zone-IA

What feature should be enabled to recover deleted objects in S3?

• Cross-region replication

• S3 versioning

• Server-side encryption

• Bucket policies

For cost-effective recovery of deleted objects within 48 hours, which storage class should be used?

• Glacier

• Standard

• Deep Archive

• Intelligent-Tiering
