CLF-C02 Question 161
Select 3Your company operates a global e-commerce platform with users located in North America, Europe, and Asia. The company must ensure low latency for users, comply with strict data sovereignty laws in specific countries, and maintain business continuity in case of a regional failure. Which of the following are appropriate reasons to use multiple AWS Regions for your infrastructure?
- A
To reduce latency for users in different geographic locations by hosting resources closer to them.
- B
To comply with local data sovereignty regulations by storing sensitive user data in specific countries.
- C
To minimize costs by using resources exclusively in the AWS Region with the cheapest pricing.
- D
To ensure business continuity by replicating workloads across multiple Regions for disaster recovery.
- E
To increase application performance by offloading traffic to a single, highly optimized Region.
Show answer and explanation
Correct answers: A, B, D
Explanation
Using multiple AWS Regions is essential for scenarios like reducing latency, complying with data sovereignty laws, and achieving business continuity through disaster recovery. Hosting resources closer to end users improves performance, while storing data in specific Regions ensures regulatory compliance. Additionally, replicating workloads across Regions provides resilience and minimizes downtime during regional outages. However, cost optimization or centralizing traffic in a single Region is not the primary reason for adopting a multi-Region strategy.
- A. Correct.
Correct: Hosting resources closer to users in different geographic locations reduces latency and improves user experience. This is a key reason to use multiple Regions.
- B. Correct.
Correct: Certain countries have strict regulations requiring sensitive data to be stored within their borders. Using specific AWS Regions helps comply with these laws.
- C. Incorrect.
Incorrect: While cost optimization is important, using multiple Regions is not primarily driven by cost considerations. In fact, using multiple Regions can sometimes increase costs.
- D. Correct.
Correct: Replicating workloads across multiple Regions ensures resilience and business continuity in case of a failure in one Region, which is a major benefit of multi-Region architecture.
- E. Incorrect.
Incorrect: Offloading traffic to a single Region is contrary to the purpose of using multiple Regions. Multi-Region setups focus on distributing resources, not centralizing them.
