Answer choices

1. A. Place all components on a single large instance to simplify troubleshooting.

3. C. Use queues, events, and managed services to reduce direct service dependencies.
4. D. Disable monitoring until the workload reaches steady production traffic.

Correct Answer

C. Use queues, events, and managed services to reduce direct service dependencies.
