AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A company has a large customer base located primarily on the west coast of the United States. They want to deploy a new web application with the lowest possible latency for their users. Which of the following deployment scenarios would BEST meet the company's performance requirements?
Deploy the application across Availability Zones in both the US East (Ohio) and the EU (Frankfurt) Regions.
Deploy the application using a single Availability Zone in the Asia Pacific (Singapore) Region for global reach.
Deploy the application across multiple Availability Zones within the US West (Oregon) Region.
Deploy the application across multiple Availability Zones within the US East (N. Virginia) Region.
Deploying the web application in the US West (Oregon) or US West (Northern California) Region would provide the lowest latency for users primarily located on the west coast of the United States. While other US regions could also host the application, their greater distance to the west coast would likely result in higher latency. Availability Zones within the chosen region can be used for high availability. Using a region outside the US is not appropriate in this case due to increased latency concerns.
