Discussion
SQL Server supports two kinds of indexes: clustered and nonclustered.
Answer: A
Correct answer: True
A clustered index holds the data rows at its leaf level in index order, so there can be only one; a nonclustered index holds keys and pointers, and there may be many. Every other kind of index in SQL Server is a variation on these two, and the choice of which column carries the clustered index is the more consequential decision.
