For a containerized service, an architect is reviewing placement groups requirement set 5. 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 cluster placement for low-latency tightly coupled compute.
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

B. Use cluster placement for low-latency tightly coupled compute.

Explanation

The best answer applies placement groups: use cluster placement for low-latency tightly coupled compute. The other options increase operational risk, weaken security, or remove observability that an AWS Solutions Architect should preserve.
