Public demo
AWS Solutions Architect Associate demo scenario
This is an original sample format preview. It is not pulled from the live question bank.
A web application must stay available if one Availability Zone fails. The application uses EC2 instances behind a load balancer. Which design best meets the requirement?
A. Place all instances in one Availability Zone to simplify routing.
B. Deploy instances across multiple Availability Zones and route traffic through an Application Load Balancer.
C. Store the application code only on one instance's local disk.
D. Disable health checks so traffic never shifts away from failed instances.
Show answer and rationale
Answer: B
Multi-AZ compute behind a load balancer improves availability because traffic can continue to healthy targets in another Availability Zone when one zone has a problem.
