01Design a scalable and secure approach for Linux filesystem hierarchy in a mid-sized engineering organization.
A system-design answer
Say this first: Linux filesystem hierarchy should be explained through its purpose, the boundary where it applies, and the evidence that shows it is working.
Use a real scenario
Imagine an internal support assistant that answers from approved policy documents. The team must decide how to apply Linux filesystem hierarchy, verify the result, and explain the user impact. For a Linux Administrator, attach the explanation to an evaluation set and retrieval trace.
Show judgment
- define boundaries, ownership, failure modes, and the operational feedback loop.
- State the constraint that could change your decision, such as scale, data sensitivity, recovery target, or team ownership.
- Call out prompt injection and unsupported answers and the control that reduces it.
Concrete check
