Loading Strategies interview questions

1. A.fetching related data automatically on first access to a navigation, requiring proxies and risking many small extra queries
2. B.pulling related data in the same query using Include so navigations are populated up front
3. C.the operator that continues eager loading into a navigation of an already-included related entity
4. D.the inefficiency where iterating a parent list issues one extra query per item to fetch its related rows, often caused by lazy loading

Answer + AI explanation with Pro

1. A.eager loading
