SAA-C03 Q491 · Storage

Question

A company runs its critical storage application in the AWS Cloud. The application uses Amazon S3 in two AWS Regions. The company wants the application to send remote user data to the nearest S3 bucket with no public network congestion. The company also wants the application to fail over with the least amount of management of Amazon S3. Which solution will meet these requirements?

Accepted Answer

**Answer D** satisfies every requirement:

1. **'Send data to nearest S3 bucket'**: S3 Multi-Region Access Points (MRAP) provide a **single global endpoint** that automatically routes requests to the S3 bucket with the **lowest network latency** using AWS Global Accelerator's anycast IP routing under the hood. Users don't need to know which Region they're hitting.

2. **'No public network congestion'**: MRAP routes traffic over the **AWS global backbone network**, not the public internet, reducing latency and avoiding internet congestion.

3. **'Failover with least management'**: Active-active configuration with MRAP means if one Region becomes unavailable, traffic is **automatically redirected** to the healthy Region. There's no manual DNS change or application reconfiguration needed.
