• Terribly phrased options to choose.

    A clustered index physically rearanges data on disk.

    rearranges?

    I think this option should look like this: "When created or rebuilded, a clustered index physically rearranges data on disk".

    A quote from the explanation (and from the Delaney's book):

    Once created, a clustered index is maintained logically rather than physically.

    ...

    After that (after creation), maintaining the clustered index is a logical operation.

    Another option from the question:

    Dropping a rebuilding a clustered index on a partition scheme will move disk to other drives.

    Maybe, "Dropping and rebuilding"?

    "Move disk to other drives" – what is the meaning of this? Sounds like abracadabra for me 🙂

    Maybe, it means "moving logical disks C:, D:, E: to other hard disk drives"? :hehe:
