Hello Prem,

The syntax the question gives for DROP TABLESPACE doesn't
look right to me. Without looking at the current docs<grin>,
I believe INCLUDING CONTENTS is a valid option, and that the
others are invalid. Thus, answer B, the statement will fail,
looks correct. Whoever wrote that test question does not
appear to have tested their test.

As for question 2, until you asked, I too would have looked
in DBA_EXTENTS. But as I look at one table in my database, I
see that DBA_SEGMENTS.BLOCKS reports the same value as
DBA_EXTENTS.BLOCKS. It may be that DBA_SEGMENTS reports on
SUM(BLOCKS) for all extents in each segment. Interesting.
I'll have to read the docs on this, to find out for certain
what's going on.

One thing to be aware of with respect to question 2 below is
that in a partitioned table, each partition is a segment.
Thus, whether you go to DBA_EXTENTS or DBA_SEGMENTS, you do
need to be sure to consider all partitions of the table in
question.

Best regards,
