Answer choices

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. Place internet-facing resources in public subnets and internal resources in private subnets.

Correct Answer

D. Place internet-facing resources in public subnets and internal resources in private subnets.
