Apply the archive redo logs.5. Restore the data file.6. Take the SYSAUX tablespace offline.7. Place the SYSAUX tablespace online.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.6，5，4，7

B.10，1，2，5，8

Your multitenant container database (CDB) contains three pluggable database (PDBs). You find that the control file is damaged. You plan to use RMAN to recover the control file. There are no startup triggers associated with the PDBs.Which three steps should you perform to recover the control file and make the database fully operational?（）

A. Mount the container database (CDB) and restore the control file from the control file auto backup.

B. Recover and open the CDB in NORMAL mode.

C. Mount the CDB and then recover and open the database, with the RESETLOGS option.

D. Open all the pluggable databases.

E. Recover each pluggable database.

F. Start the database instance in the nomount stage and restore the control file from control file auto backup.

Your multitenant container database (CDB) contains a pluggable database, HR_PDB. The default permanent tablespace in HR_PDB is USERDATA. The container database (CDB) is open and you connect RMAN.You want to issue the following RMAN command:RMAN > BACKUP TABLESPACE hr_pdb:userdata;Which task should you perform before issuing the command?（）

A. Place the root container in ARHCHIVELOG mode.

B. Take the user data tablespace offline.

C. Place the root container in the nomount stage.

D. Ensure that HR_PDB is open.

A. All administration tasks must be done to a specific pluggable database.

B. The pluggable databases increase patching time.

C. The pluggable databases reduce administration effort.

D. The pluggable databases are patched together.

E. Pluggable databases are only used for database consolidation.

A. The C # # ROLE1 role is created in the root database and all the PDBs.

B. The C # # ROLE1 role is created only in the root database because the container clause is not used.

C. Privileges are granted to the C##A_ADMIN user only in the root database.

D. Privileges are granted to the C##A_ADMIN user in the root database and all PDBs.

E. The statement for granting a role to a user fails because the CONTAINER clause is not used.
