[DEVELOPER] Advanced Storage Topics

Question 1

What is S3 Transfer Acceleration?

Answer 1

A feature that enables fast, easy, and secure transfers of files over long distances by utilizing CloudFront’s edge locations on the AWS global network.

Question 2

When would you use S3 Multi-Region Access Points?

Answer 2

When you need a single, global endpoint to access data that is replicated across multiple S3 buckets in different AWS regions.

This is for building high-availability, multi-region applications.

Question 3

How does a developer prevent incomplete Multi-Part Uploads from incurring storage costs?

Answer 3

Configure an S3 Lifecycle Rule to abort incomplete multi-part uploads after a specific number of days.

Question 4

What is the current recommended General Purpose SSD volume, and what is its key advantage?

Answer 4

General Purpose SSD (gp3). It is cheaper than gp2 and allows you to provision IOPS and throughput independently of the volume size.

Question 5

Which EBS volume is designed for mission-critical apps requiring the highest performance and sub-millisecond latency?

Answer 5

Provisioned IOPS SSD (io2) Block Express. It is the premium volume type, providing the highest IOPS and throughput with consistent performance.

Question 6

What is S3 Intelligent-Tiering?

Answer 6

A storage class that automatically moves objects between frequently accessed and infrequently accessed tiers based on access patterns. It’s recommended when access patterns are unknown or changing.

Question 7

What is the primary trade-off when using S3 One Zone-IA?

Answer 7

It offers a lower cost than Standard-IA, but data is stored in only one Availability Zone. The data is lost if the AZ is destroyed.

Question 8

What is the primary purpose of the AWS Snow Family (e.g., Snowball)?

Answer 8

Physical transfer of Petabytes of data to/from AWS when network connectivity is non-existent, too slow, or too costly.

Question 9

What AWS service powers S3 Multi-Region access points?

Answer 9

Global Accelerator

Question 10

A developer wants to intercept and modify requests to an S3 bucket (e.g., resizing images on the fly). Which feature should be used?

Answer 10

S3 Object Lambda

S3 Object Lambda allows you to add your own code to S3 GET requests to modify data as it is returned to the application.
