CLF-C02 Question 214
Select 3A company wants to improve the performance and availability of its globally distributed web application while also reducing latency for users. Which AWS services can the company use to achieve this goal?
- A
Amazon CloudFront
- B
AWS Global Accelerator
- C
AWS Direct Connect
- D
Amazon Simple Queue Service (SQS)
- E
Amazon Route 53
Show answer and explanation
Correct answers: A, B, E
Explanation
To improve the performance and reduce latency for a globally distributed application, Amazon CloudFront can cache content at edge locations, AWS Global Accelerator ensures optimal routing to AWS endpoints with low latency, and Amazon Route 53 can direct users to the nearest resources based on latency. These services work together to enhance the user experience for global applications.
- A. Correct.
Amazon CloudFront is a content delivery network (CDN) that helps improve the performance and reduce latency of delivering content to users by caching it at edge locations around the world. This is a suitable choice for improving global application performance.
- B. Correct.
AWS Global Accelerator improves the availability and performance of applications by routing traffic to the optimal AWS endpoint (such as a region or edge location) based on latency and health checks. It is ideal for globally distributed applications.
- C. Incorrect.
AWS Direct Connect is a network service that provides a dedicated connection between your on-premises environment and AWS. While it improves connectivity, it does not directly address global latency reduction for distributed applications.
- D. Incorrect.
Amazon Simple Queue Service (SQS) is a message queuing service. While useful for decoupling application components, it does not directly improve performance or reduce latency for globally distributed applications.
- E. Correct.
Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service. It can be used to route users to the closest AWS region or endpoint based on latency, which helps improve the performance of globally distributed applications.
