I read question and answers many times because of high score.
I was searching for the swindle!
But it's only a straightforward basic question.
:-D

+1

I thought I knew what the answer was as soon as I read the question, then I saw the points value and wondered what the catch was. After a load of research and reading round I found out I was right after all.

Same here :-)

nice question... i got 4 points :-D
Clustered Index will created for second table only not for first table. Other wise we can create non clustered index for the first table which have foreign key constraint.
