How would you answer an interview scenario involving DbContext and DbSet in Entity Framework Core?

For an interview scenario involving DbContext and DbSet, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. DbContext represents a unit of work with the database, while DbSet exposes a queryable collection for an entity type. For production, use a short-lived scoped DbContext in web applications, async database calls, and never share a context across threads. 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.
