CLF-C01 practice question 25 of 35

A company's headquarters is located on a different continent from where the majority of the company's customers live. The company wants an AWS Cloud environment setup that will provide the lowest latency to the customers. Which solution will provide the LOWEST network latency between the AWS resources and the customers?

Full set: 370 questions
Answer options
A: Place the resources in the AWS Region that is closest to the company's headquarters. Move the resources to the Availability Zone that is closest to the customers.
B: Place all workloads in the AWS Region that is closest to the company's headquarters.
C: Place all workloads in the AWS Region that is closest to the majority of customers. Correct answer
D: Place the resources in AWS edge locations that are closest to the company's headquarters.
Correct Answer:
C. Place all workloads in the AWS Region that is closest to the majority of customers.
Explanation

Network latency is primarily influenced by the physical distance between the end-user and the server hosting the application. To provide the lowest latency for customers, the application's resources (such as compute and databases) should be deployed in the AWS Region that is geographically closest to the majority of those customers. This minimizes the round-trip time for data packets, resulting in a faster and more responsive user experience. Placing resources near the company's headquarters would increase latency for the distant customer base.

Why Incorrect

A. Availability Zones exist within a single AWS Region and cannot be moved to different continents. This option is technically infeasible.
B. Placing workloads near the company's headquarters would maximize latency for customers located on a different continent, directly contradicting the requirement.
D. AWS edge locations are primarily for caching content (Amazon CloudFront) and DNS (Route 53), not for hosting primary application workloads.
