Re: Todays Oracle 11.2.0.2 quiz...

For a quiz I pick "C", for my large database environments that are reality, I would have to say for the majority of objects, "C" is fine and for 20%, I need "A" and other options...  Now ask me why I think my developers choices in code, hints that are in use and design demand the change and it's not Oracle fault... :)
