Demo Question 6.
Assuming you are given enough time and storage to reorganize poorly performing B. Tree indexes, which statement correctly describes the action you should take and the resulting benefit?
A. Drop the indexes in question and create new indexes as bitmap indexes because bitmap indexes are compact.
B. Drop the indexes in question and recreate them because it is always faster to recreate than to use any other method.
C. Coalesce the indexes because it will move them to another tablespace and quickly free up index leaf blocks for use.
D. Rebuild the indexes in question because that will shrink the heights of the trees wherever applicable.
