Oracle Database 12c: RAC Administration — Question 57

Which two statements are true about the UNDROP clause of the ALTER DISKGROUP statement?

Answer options

• A. It cancels pending drops of disks dropped using the DROP DISKGROUP command.
• B. A disk cannot be undropped as a result of a drop diskgroup.
• C. It automatically unmounts the disks after successfully undropping them.
• D. It is not possible to cancel pending drops of disks dropped using the force option.

Correct answer: B, D

Explanation

Option B is correct because once a diskgroup is dropped, the disks in it cannot be restored. Option D is also correct since using the force option prevents cancellation of pending drops. Options A and C are incorrect as they misrepresent the functionality of the UNDROP clause.
