AWS Solutions Architect Associate (SAA-C02) Exam Prep Course - 2021 UPDATED! - Amazon Simple Storage Service (Amazon S3)

The video tutorial covers key concepts of Amazon S3 storage, including prefixes and delimiters for organization, various storage classes and their cost implications, and object lifecycle management. It also explains encryption methods, both server-side and client-side, and discusses versioning, multi-factor authentication delete, multi-part uploads, range gets, cross-region replication, and logging. These concepts are essential for efficient data management and cost-effective storage solutions in AWS S3.

What is the purpose of prefixes and delimiters in AWS S3?

• To create actual folder hierarchies

• To manage data lifecycle

• To encrypt data in transit

• To organize data without traditional folders

Which AWS S3 storage class is the most cost-effective for infrequently accessed data?

How does server-side encryption work in AWS S3?

• Data is encrypted before uploading

• Data is encrypted after reaching the server

• Data is encrypted using client-side keys

• Data is encrypted during transit

What is a key characteristic of versioning in AWS S3?

• It is enabled by default

• It can be disabled after enabling

• It allows multiple versions of an object

• It automatically deletes old versions

What is the purpose of MFA delete in AWS S3?

• To log all bucket activities

• To replicate data across regions

• To require multiple factors for deleting files

• To encrypt data during upload

What does cross-region replication in AWS S3 achieve?

• It encrypts data across regions

• It replicates existing data in the bucket

• It logs data access events

• It localizes data in another region
