Oracle OCP 1Z0 053 Q10
10.Consider the following scenario for your database:
-Backup optimization is enabled in RMAN. The recovery window is set to 7 days in RMAN. The most
recent backup to disk for the TOOLS tablespace was taken on November 3, 2007.
The TOOLS tablespace is read-only since November 4, 2007.
On November 23, 2007, you issue the RMAN command to back up the database to disk. Which statement
is true regarding the backup of the TOOLS tablespace?
A. The RMAN backup fails because the TOOLS tablespace is read-only
B. The RMAN skips the backup of the tablespace because backup optimization is enabled
C. The RMAN makes backup because optimization can be enabled only for backups to disk
D. The RMAN makes the backup because no backup of the tablespace exists within the seven day
window
Answer: D
尽管开启了backup optimization, 但是recovery window是7天。
开启了backup optimization, read only的datafile可能被跳过
