• B、The operation would fail if tbs_1 were a read/write tablespace.
• C、The operation would fail if tbs_1 were the default tablespace for the database.
• D、If the above operation were successful， media recovery would be required to bring the tablespace online.
• E、If the above operation were successful， instance recovery would be required to bring the tablespace online.

第7题：

You have a read-only tablespace on read-only media. You want to perform a media recovery on the existing data files， but using a backup control file. The backup control file indicates that the status of the read-only tablespace was read/write when the control file was backed up. What should you consider？（）

• A、 take data files from the read-only tablespace offline before performing a recovery
• B、 recovery using backup control file is not possible， so restore all the files from the last full database backup， and then open the database
• C、 drop the read-only tablespace and re-create the tablespace after recovery
• D、 perform a recovery； status of the tablespace in control file will be changed automatically

第8题：
