Which three statements are true about using flashback database in a multitenant container database (CDB)?

• A.To enable flashback database, the CDB must be mounted.
• B.A CDB can be flashed back specifying the desired target point in time or an SCN, but not a restore point.
• C.Individual PDBs can be flashed back without flashing back the entire CDB.
• D.The root container can be flashed back without flashing back the pluggable databases (PDBs).
• E.The DB_FLASHBACK RETENTION_TARGET parameter must be set to enable flashback of the CDB.

Your multitenant container (CDB) containing three pluggable databases (PDBs) is running in ARCHIVELOG mode. You find that the SYSAUX tablespace is corrupted in the root container.
The steps to recover the tablespace are as follows:
1. Mount the CDB.
2. Close all the PDBs.
3. Open the database.
4. Apply the archive redo logs.
5. Restore the data file.
6. Take the SYSAUX tablespace offline.
7. Place the SYSAUX tablespace offline.
8. Open all the PDBs with RESETLOGS.
9. Open the database with RESETLOGS.
10. Execute the command SHUTDOWN ABORT.
Which option identifies the correct sequence to recover the SYSAUX tablespace?

• A.10, 1, 2, 5, 8
• B.10, 1, 2, 5, 4, 9, 8
• C.10, 1, 5, 8, 10
• D.6, 5, 4, 7

You are administering a database stored in Automatic Storage management (ASM). The files are stored in the DATA disk group. You execute the following command:

What is the result?

• A.The file `myfile.dbf' is created in `+data/prod' and the reference to `+data.231.45678' in the data dictionary removed.
• B.The file `+data.231.45678' remains in the same location andasynonym'myfile.dbf' is created.
• C.The file `+data.231.45678' is renamed as `myfile.dbf', and copied to `+data/prod'.
• D.The file `+data.231.45678' is physically relocated to `+data/prod' and renamed as `myfile.dbf'.

Which two statements are true about Enterprise Manager (EM) express in Oracle Database 12c?
(Choose two.)

• A.You can create and configure pluggable databases by using EM express.
• B.Multiple databases on the same node (or host) may each be individually managed by using EM Express.
• C.You can perform basic administrative tasks for pluggable databases by using the EM express interface.
• D.By default, EM express is available for a database after database creation.
• E.You cannot start up or shut down a database instance by using EM express.

Which two statements are true about variable extent size support for large ASM files?

• A.An ASM Instance automatically allocates an appropriate extent size.
• B.Rebalance operations are completed faster than with a fixed extent size
• C.The metadata used to track extents in SGA is reduced.
• D.Performance improves in a stretch cluster configuration by reading from a local copy of an extent.
• E.Resync operations are completed faster when a disk comes online after being taken offline.
