AWS S3 Data Durability

Exam Scenario Question :-

A customer is leveraging Amazon Simple Storage Service in eu-west-1 to store static content for web-based property. The customer is storing objects using the Standard Storage class. Where are the customers’ objects replicated?

1. Single facility in eu-west-1 and a single facility in eu-central-1
2. Single facility in eu-west-1 and a single facility in us-east-1
3. Multiple facilities in eu-west-1
4. A single facility in eu-west-1

Answer :-

The question targets the S3 Data Durability which mentions the objects are stored redundantly across multiple facilities in the same Amazon S3 region.

Amazon S3 provides a highly durable storage infrastructure designed for mission-critical and primary data storage. Objects are redundantly stored on multiple devices across multiple facilities in an Amazon S3 region. To help better ensure data durability, Amazon S3 PUT and PUT Object copy operations synchronously store your data across multiple facilities before returning SUCCESS. Once the objects are stored, Amazon S3 maintains their durability by quickly detecting and repairing any lost redundancy.
