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

The video tutorial covers Amazon S3's performance capabilities, including request limits per prefix and the impact of KMS encryption on performance. It explains how to optimize S3 performance using multi-part uploads and transfer acceleration. Additionally, it discusses efficient file retrieval methods using byte range fetches to enhance download speeds.

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

• 3500

• 5500

• 10000

• 2000

What can be achieved by spreading reads across multiple prefixes in an S3 bucket?

• Higher request throughput

• Reduced storage capacity

• Increased latency

• Lower security

How does KMS encryption affect S3 performance?

• It increases the number of requests per second.

• It has no impact on performance.

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

• It decreases the storage capacity.

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

• Compressed upload

• Encrypted upload

• Multi-part upload

• Single upload

What is the purpose of S3 transfer acceleration?

• To increase storage capacity

• To enhance security

• To speed up data transfer by using edge locations

• To reduce costs

How does S3 byte-range fetches improve download efficiency?

• By reducing the file size

• By compressing the data

• By allowing parallelized requests for specific byte ranges

• By encrypting the data

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

• Enhanced encryption

• Reduced storage costs

• Improved resilience in case of failures

• Increased upload speed
