AWS Certified Data Analytics Specialty 2021 - Hands-On! - S3 Encryption (Reminder)

The video tutorial explains four methods of encrypting objects in Amazon S3: SSE-S3, SSE-KMS, SSE-C, and client-side encryption. It details how each method works, the management of encryption keys, and the importance of encryption in transit using SSL/TLS. The tutorial emphasizes understanding these methods for AWS exams and practical applications.

Which of the following is NOT a method of encryption provided by Amazon S3?

• SSE-S3

• SSE-SSL

• SSE-KMS

• SSE-C

What is the primary algorithm used in SSE-S3 encryption?

• SHA-256

• AES 256

• Blowfish

• RSA 2048

What advantage does SSE-KMS offer over SSE-S3?

• Faster data retrieval

• Control over access to encryption keys

• Lower cost

• Automatic key rotation

In SSE-C, who is responsible for managing the encryption keys?

• No keys are used

• A third-party service

• The client

• AWS

What is a key requirement when using SSE-C for data transfer?

• Using SFTP protocol

• Using FTP protocol

• Using HTTPS protocol

• Using HTTP protocol

In client-side encryption, who is responsible for encrypting the data before uploading to S3?

• No encryption is needed

• A third-party service

• AWS

• The client

What does encryption in transit ensure when using HTTPS with Amazon S3?

• Data is compressed

• Data is encrypted during transfer

• Data is stored in multiple locations

• Data is automatically backed up
