SAP-C02 Question 17
Select 3Your organization operates a global e-commerce platform and requires a highly available architecture that minimizes latency for users in different regions. You have been asked to design a solution that ensures low latency for end-users, provides disaster recovery capabilities, and adheres to regulatory requirements to store sensitive data within specific geographic locations. Which combination of AWS services and features would best meet these requirements?
- A
Deploy resources across multiple AWS Regions to serve users in different geographic locations.
- B
Use AWS Global Accelerator to route user traffic to the nearest healthy endpoint based on latency.
- C
Enable Amazon S3 Cross-Region Replication to automatically replicate sensitive data to different Regions for disaster recovery.
- D
Use AWS Outposts to deploy AWS services in on-premises data centers for low latency.
- E
Deploy resources across multiple Availability Zones (AZs) within a single AWS Region for high availability.
Show answer and explanation
Correct answers: A, B, C
Explanation
To meet the requirements of low latency, disaster recovery, and data residency, deploying resources across multiple AWS Regions ensures global coverage and compliance with regulatory requirements. AWS Global Accelerator further improves latency and availability by directing users to the nearest healthy endpoint. Amazon S3 Cross-Region Replication supports disaster recovery by replicating sensitive data across Regions. While deploying resources across AZs ensures high availability, it does not address global latency or disaster recovery. AWS Outposts is not suitable for a global cloud-based architecture designed to optimize latency and availability for end-users worldwide.
- A. Correct.
This option is correct because deploying resources across multiple AWS Regions reduces latency for users in different geographic locations and provides disaster recovery capabilities by leveraging AWS's global infrastructure.
- B. Correct.
This option is correct because AWS Global Accelerator routes traffic to the nearest healthy endpoint, optimizing performance and providing low latency for end-users.
- C. Correct.
This option is correct as Amazon S3 Cross-Region Replication enables automatic replication of sensitive data to different Regions, adhering to disaster recovery requirements and regulatory compliance for geographic data storage.
- D. Incorrect.
This option is incorrect because AWS Outposts is primarily used for extending AWS services to on-premises environments. While it can provide low latency for specific use cases, it is not designed for a global solution for end-user traffic and latency optimization.
- E. Incorrect.
This option is incorrect because deploying resources across multiple AZs within a single Region provides high availability within that Region but does not address global latency or disaster recovery requirements across Regions.
