S3 storage class optimization in AWS - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of S3 storage classes?

S3 storage classes help organize data by cost and access frequency, so you pay less for storing data you don't use often.

beginner

Name two S3 storage classes designed for infrequently accessed data.

S3 Standard-Infrequent Access (Standard-IA) and S3 One Zone-Infrequent Access (One Zone-IA) are for data accessed less often but still need quick retrieval.

How does S3 Intelligent-Tiering optimize storage costs?

It automatically moves data between frequent and infrequent access tiers based on usage, so you don't have to guess which class to use.

intermediate

What is the main difference between S3 Glacier and S3 Glacier Deep Archive?

S3 Glacier is for long-term archive with retrieval times in minutes to hours, while Glacier Deep Archive is cheaper but retrieval takes up to 12 hours.

intermediate

Why should you consider lifecycle policies in S3 storage class optimization?

Lifecycle policies automate moving or deleting objects based on age or access patterns, saving money and managing data efficiently.

Which S3 storage class is best for data accessed frequently?

A S3 One Zone-IA

B S3 Glacier

C S3 Standard

D S3 Glacier Deep Archive

S3 Standard is designed for frequently accessed data with low latency.

What does S3 Intelligent-Tiering do?

A Automatically moves data between access tiers based on usage

B Deletes data after 30 days

C Stores data only in one availability zone

D Encrypts data at rest

It automatically moves objects between frequent and infrequent access tiers to optimize cost.

Which storage class is cheapest for long-term archival but has slow retrieval?

A S3 Glacier Deep Archive

B S3 Standard-IA

C S3 Intelligent-Tiering

D S3 One Zone-IA

S3 Glacier Deep Archive offers the lowest cost but retrieval can take up to 12 hours.

What is a benefit of using lifecycle policies in S3?

A Manually move data between classes

B Automatically manage data movement and deletion

C Increase storage costs

D Disable versioning

Lifecycle policies automate transitions and deletions to optimize storage costs.

Which S3 storage class stores data in a single availability zone?

A S3 Standard

B S3 Intelligent-Tiering

C S3 Glacier

D S3 One Zone-IA

S3 One Zone-IA stores data in one availability zone and costs less but has less resilience.

Explain how S3 storage classes help optimize storage costs.

Think about how you pay less for things you use less often.

Describe the differences between S3 Standard, Standard-IA, and Glacier storage classes.

Consider how fast you need the data and how often you use it.
