Question 430
An AWS planning meeting highlights two independent requirements. Finding 1: A public API becomes slow because one server processes all requests even though demand varies by time of day. Finding 2: A team evaluates a new database service by its cheapest hourly rate alone, ignoring operational effort and service constraints. Which two-part response addresses both findings in order?
Explanation
Correct Answer
For finding 1: Performance efficiency matches capacity and architectural choices to the actual workload rather than a fixed assumption. For finding 2: Well-Architected decisions require balancing trade-offs instead of optimizing one metric in isolation. Both actions are required.
Incorrect Answers
The actions are reversed. The correct order is (1) Apply the Performance Efficiency pillar to select suitable services and use measured elastic scaling where appropriate. (2) Compare performance, reliability, security, and costs together against the documented business requirement.
For finding 2: Well-Architected decisions require balancing trade-offs instead of optimizing one metric in isolation. That action addresses a different situation: An application is moved to a managed platform, but the security team assumes the service provider automatically grants only appropriate user access.
For finding 1: Performance efficiency matches capacity and architectural choices to the actual workload rather than a fixed assumption. That action addresses a different situation: A development account gives all application workers administrator privileges because that is easier than defining their roles.
