Re: exam question

Vladimir and Mladen , I did try it out myself as I mentioned at the end of my original post, My problem is not with the question but with the answer given in the test. I think its wrong.
  I was thinking that dba_extents and dba_segments would be the correct  answer
  because i could use :
  select tablespace_name, sum(bytes) from dba_extents group by  tablespace_name
  ;

  select tablespace_name, sum(bytes) from dba_segments group by   tablespace_name;

  But The answer given says dba_extents and dba_data_files. Is the given   answer wrong or is there some way of finding out from dba_data_files how   much space is used up in a tablespace

  For that matter what does the question want to know ? does it want to know   how much space do the tablespaces have ( that would be the sum of the sizes
  of the data files ) or how much is ""used up"" ?
