Answer Key and Explanations
Check these only after attempting every question.
1. B - resource
Everything about invoices then lives in one file.
2. B - makes the service depend on FastAPI
It can no longer be called from a worker without a web framework.
3. B - in one place in the router layer
So every endpoint translates the same exception the same way.
4. B - one client module
Otherwise the vendor's types spread through your logic.
5. B - a newcomer finds the right file unaided
Not elegance - whether 'where does X go?' has one predictable answer.
Practical Check
Apply this module to your own work: complete the module activity for *Routers, Larger Project Structure and Service Layers*, then write one sentence naming what your result shows and one naming what it does not.
Strong Answer Pattern
A strong answer names the task, the evidence used, the check performed, and the remaining limitation. It avoids "proved", "guaranteed", or "always" unless the evidence genuinely supports it.
