How would you answer an interview scenario involving change tracking and AsNoTracking in Entity Framework Core?

For an interview scenario involving change tracking and AsNoTracking, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. EF Core tracks entity state so SaveChanges can generate inserts, updates, and deletes; AsNoTracking disables tracking for read-only queries. In this scenario, a read-heavy endpoint slows down with large result sets. Explain how you would verify whether change tracking is contributing. For production, use tracking for update workflows and AsNoTracking for read-only projections and list endpoints. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
