AWS Certified Data Analytics Specialty 2021 – Hands-On - S3 Performance

The video tutorial explains Amazon S3's performance capabilities, including request limits per prefix and the impact of KMS encryption on performance. It covers techniques to optimize S3 performance, such as multi-part uploads, transfer acceleration, and byte range fetches, to enhance upload and download speeds.

What is the maximum number of GET and HEAD requests per second per prefix in an S3 bucket?

• 3500

• 5500

• 22000

• 10000

What is the impact of spreading reads across multiple prefixes in an S3 bucket?

• It decreases the number of requests per second.

• It increases the total requests per second achievable.

• It has no impact on performance.

• It reduces the storage capacity.

How does KMS encryption affect S3 performance?

• It may lead to throttling if KMS quotas are exceeded.

• It reduces the storage capacity of S3.

• It increases the number of requests per second.

• It has no impact on performance.

What is the recommended method for uploading files larger than 100 MB to S3?

• Single-part upload

• Multi-part upload

• Direct upload

• Compressed upload

What is the purpose of S3 transfer acceleration?

• To increase storage capacity

• To enhance security

• To reduce data redundancy

• To speed up data transfers by using edge locations

How does S3 byte-range fetches improve download efficiency?

• By compressing the files

• By reducing the number of requests

• By allowing parallelized retrieval of specific byte ranges

• By increasing the storage capacity

What is a potential benefit of using byte-range fetches?

• It decreases the number of requests needed.

• It enables partial file retrieval, such as headers.

• It increases the file size.

• It allows for complete file retrieval only.
