CLF-C02 Question 160
Select 3Your company operates an e-commerce platform with customers across North America and Europe. You need to ensure low latency for users in both regions, comply with European data sovereignty laws, and enable disaster recovery in the event of a Regional failure. Which AWS design choices should you implement?
- A
Deploy your application in multiple AWS Regions, with one in North America and one in Europe.
- B
Use a single AWS Region in North America to centralize operations and reduce costs.
- C
Enable cross-Region replication for critical data between the North American and European Regions.
- D
Store all user data in a single Region, regardless of user location, to simplify compliance requirements.
- E
Implement Amazon Route 53 for latency-based routing to direct users to the closest Region.
Show answer and explanation
Correct answers: A, C, E
Explanation
The correct answers involve deploying in multiple Regions to meet low latency and data sovereignty needs, enabling cross-Region replication for disaster recovery, and using Amazon Route 53 for latency-based routing. These choices align with best practices for ensuring business continuity, compliance, and optimal user experience across different geographical locations.
- A. Correct.
Deploying your application in multiple AWS Regions ensures that you can maintain low latency for users in both North America and Europe, while also meeting data sovereignty requirements by storing European data in the European Region.
- B. Incorrect.
Using a single AWS Region in North America might reduce costs but would result in higher latency for European users and fail to meet European data sovereignty requirements.
- C. Correct.
Enabling cross-Region replication ensures that your critical data is backed up across Regions, supporting disaster recovery needs in case of a Regional failure.
- D. Incorrect.
Storing all user data in a single Region simplifies operations but does not meet data sovereignty requirements for European users and may lead to high latency for users outside that Region.
- E. Correct.
Amazon Route 53’s latency-based routing ensures that users are directed to the closest Regional deployment, reducing latency and improving user experience.
