SAP-C02 Question 481
Select 3Your organization operates a global e-commerce platform and requires high availability, low latency, and disaster recovery across multiple continents. You are tasked with designing a cloud infrastructure that utilizes AWS's global infrastructure to meet these requirements. Which combination of AWS services and features would best fulfill these requirements?
- A
Deploy the application across multiple AWS Regions and use Amazon Route 53 for latency-based routing.
- B
Use AWS Local Zones to host the application closer to users in specific cities.
- C
Configure multi-AZ deployments for the application's database in each Region.
- D
Host the entire application in a single Region and use AWS CloudFront for content delivery.
- E
Enable global replication of the application's data using AWS Global Tables.
Show answer and explanation
Correct answers: A, C, E
Explanation
To achieve high availability, low latency, and disaster recovery, it is crucial to deploy resources across multiple AWS Regions and leverage services like Route 53 for latency-based routing to direct traffic to the nearest Region. Multi-AZ deployments enhance database availability within each Region, while AWS Global Tables ensure data is replicated globally and accessible with low latency. These features together provide a robust global infrastructure for a highly available and fault-tolerant application.
- A. Correct.
Deploying across multiple AWS Regions ensures high availability and disaster recovery. Amazon Route 53 latency-based routing reduces latency by directing users to the closest Region.
- B. Incorrect.
AWS Local Zones are designed for ultra-low latency use cases in specific cities but do not address global availability or disaster recovery.
- C. Correct.
Multi-AZ deployments improve database availability within each Region and ensure resilience against failures in a single Availability Zone.
- D. Incorrect.
Hosting in a single Region does not address global disaster recovery needs and may introduce latency for users far from the Region, even with AWS CloudFront.
- E. Correct.
AWS Global Tables provide seamless, low-latency data replication across multiple Regions, ensuring global availability and disaster recovery.
