Question

which of the statements are correct?

A a clustered index offers much better performance than unclustered index for range queries

B a clustered index istypically less expensive to manage than unclustered index

Comments

I think Both are Correct
a) Clustered Index is in the same way that actual rows of table are stored in sorted order based on some key value, hence it is useful for range queries.
b) For clustered index we can even 1 entry for each data block therefore its quite sparse and less expensive.

Answer 1

Both are correct

a)as clustered index is sorted.

b) Clustered index is sparse as it consists of unique key values.
