user_data is a nonencryptedtablespace containing tables with data. You must encrypt ail data in this tablespace.
Which three methods can do this?
- A. Use Data Pump.
- B. Use ALTERTABL
- C. . .MOVE
- D. Use CREATE TABLE AS SELECT
- E. Use alter tablespace to encrypt the tablespace after enabling row movement on all its
- F. Use altertablespace to encrypt the tablespac
Explanation: Finally, note that you can only create encrypted tablespaces; you cannot modify existing tablespaces to encrypt them. So, when you need existing data in encrypted tablespaces, the best solution is to first create encrypted tablespaces and then move the objects from the unencrypted tablespaces to them.

NEW QUESTION 10
Your database is running in archivelog mode. Examine the parameters for your database instance: LOG_ARCHIVE_DEST_l ='LOCATION=/disk1/arch MANDATORY'
LOG_ARCHIVE_DEST_2 ='LOCATION=/disk2/arch' LOG_ARCHIVE_DEST_3 ='LOCATIO=/disk3/arch' LOG_ARCHIVE_DEST _4 ='LOCATIONs/disk4/arch' LOG_ARCHIVE _MIN_SUCCEED_DEST = 2

Which statement is true about the loss or damage of a temp file that belongs to the temporary tablespace of a pluggable database (PDB)?
- A. The PDB is closed and the temp file is re-created automatically when the PDB is opened.
- B. The PDB is closed and requires media recovery at the PDB level.
- C. The PDB does not close and the temp file is re-created automatically whenever the containerdatabase (CDB) is opened.
- D. The PDB does not close and starts by using the default temporary tablespace defined for the CD

The PDB can open with a missing temporary file. If any of the temporary files do not exist when the PDB is opened, they are automatically re-created. They are also automatically recreated at CDB startup.

You create a default Flashback Data Archive FLA1and enable it for the EMPLOYEES table in the HR schema.

Explanation: Flashback data archives retain historical data across data definition language (DDL) changes to the database as long as the DDL change does not affect the structure of the table. The one exception to this rule is that flashback data archives do retain historical data when a column is added to the table. https://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_5009.htm
