IF A TABLESPACE HAS SEVERAL DATAFILES, SEGMENTS CAN HAVE EXTENTS IN ALL OF THEM

þ

C. If a tablespace has several datafiles, segments can have extents in all

A, B, and D. A is wrong because one extent consists of consecutive

block in one datafile. B is wrong because one segment can only exist in one

tablespace (though one tablespace can contain many segments). D is wrong

because while this can certainly be done, one block can only exist in one

datafile.
