2. B. Create a clustered index on TBL1. Create a nonclustered index on TBL2 and add the most frequently queried column as included columns.
3. C. Create a nonclustered index on TBL2 only.
4. D. Create UNIQUE constraints on both TBL1 and TBL2. Create a partitioned view that combines columns from TBL1 and TBL2.
5. E. Drop existing indexes on TBL1 and then create a clustered columnstore index. Create a nonclustered columnstore index on TBL1. Create a nonclustered index on TBL2.
6. F. Drop existing indexes on TBL1 and then create a clustered columnstore index. Create a nonclustered columnstore index on TBL1.Make no changes to TBL2.
7. G. Create CHECK constraints on both TBL1 and TBL2. Create a partitioned view that combines columns from TBL1 and TBL2. — đáp án hiện tại
