Design High-Performing Architectures Practice Question

Question

For a data lake, an architect is reviewing EFS requirement set 8. 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. Provide shared posix file storage across multiple compute instances.
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. Provide shared posix file storage across multiple compute instances.

Explanation

The best answer applies EFS: provide shared POSIX file storage across multiple compute instances. The other options increase operational risk, weaken security, or remove observability that an AWS Solutions Architect should preserve.
