Design Secure Architectures Practice Question

Question

For a public application, an architect is reviewing network ACLs requirement set 19. Which design choice best fits the requirement while following AWS architectural best practices?

Answer choices

1. A. Place all components on a single large instance to simplify troubleshooting.
2. B. Use long-lived access keys in application configuration so services can call AWS APIs directly.
3. C. Disable monitoring until the workload reaches steady production traffic.
4. D. Apply stateless subnet-level traffic rules where an extra boundary is needed.

Correct Answer

D. Apply stateless subnet-level traffic rules where an extra boundary is needed.

Explanation

The best answer applies network ACLs: apply stateless subnet-level traffic rules where an extra boundary is needed. The other options increase operational risk, weaken security, or remove observability that an AWS Solutions Architect should preserve.
