Design Cost-Optimized Architectures Practice Question

Question

For a backup modernization project, an architect is reviewing serverless workflows requirement set 2. Which design choice best fits the requirement while following AWS architectural best practices?

Answer choices

1. A. Combine lambda, api gateway, step functions, and managed data stores where idle capacity should be minimized.
2. B. Place all components on a single large instance to simplify troubleshooting.
3. C. Use long-lived access keys in application configuration so services can call AWS APIs directly.
4. D. Disable monitoring until the workload reaches steady production traffic.

Correct Answer

A. Combine lambda, api gateway, step functions, and managed data stores where idle capacity should be minimized.

Explanation

The best answer applies serverless workflows: combine Lambda, API Gateway, Step Functions, and managed data stores where idle capacity should be minimized. The other options increase operational risk, weaken security, or remove observability that an AWS Solutions Architect should preserve.
