RE: exam question

Based on the answer, I would have assumed the question really meant "used up". Thus to find out how much is used up of the total amount of space, you would need to know how much there was originally, and thus the need to query dba_data_files.

Actually I read the original post so quickly, that this what I thought the question wanted. Going back and reading more carefully I can see that my original assumption is NOT what the actual wording says.

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"" ?
