Question 16: A table named TAB_A was created with the COMPRESS YES option specified and
populated with
100,000 rows. If a DBA wants to create an index on table TAB_A, which statement is true?
A. In order for the index to be compressed, it must be enabled for compression by specifying
the
COMPRESS YES option with the CREATE INDEX statement that is used to create it.

compressed; the
ALTER INDEX command does not have to be executed.
C. In order for the index to be compressed, it must be enabled for compression by specifying
the
COMPRESS YES option in the CREATE INDEX statement used to create it; however, the
index will not
be compressed until the ALTER INDEX command is used to create an index compression
dictionary.
