You are required to migrate your 11.2.0.3 database as a pluggable database (PDB) to a multitenant container database (CDB).The following are the possible steps to accomplish this task:1. Place all the user-defined tablespace in read-only mode on the source database.2. Upgrade the source database to a 12c version.3. Create a new PDB in the target container database.4. Perform a full transportable export on the source database with the VERSION parameter set to 12 using the expdp utility.5. Copy the associated data files and export the dump file to the desired location in the target database.6. Invoke the Data Pump import utility on the new PDB database as a user with the DATAPUMP_IMP_FULL_DATABASE role and specify the full transportable import options.7. Synchronize the PDB on the target container database by using the DBMS_PDS.SYNC_ODB function.Identify the correct order of the required steps.（）

A.2，1，3，4，5，6

B.1，3，4，5，6，7

C.1，4，3，5，6，7

D.2，1，3，4，5，6，7

E.1，5，6，4，3，2

A. BACKUP PLUGGABLE DATABASE PDB1 while connected to the root container

B. BACKUP PLUGGABLE DATABASE PDB1 while connected to the PDB1 container

C. BACKUP DATABASE while connected to the PDB1 container

D. BACKUP DATABASE while connected to the boot container

E. BACKUP PLUGGABLE database PDB1 while connected to PDB2

A. It will create a multitenant container database (CDB) with only the root opened.

B. It will create a CDB with root opened and seed read only.

C. It will create a CDB with root and seed opened and one PDB mounted.

D. It will create a CDB that must be plugged into an existing cdb.

E. It will create a CDB with root opened and seed mounted.

You are connected using SQL* Plus to a multitenant container database (CDB) with SYSDBA privilegesand execute the following sequence statements:What is the result of the last SET CONTAINER statement and why is it so?（）

A. It succeeds because the PDB_ADMIN user has the required privileges.

B. It fails because common users are unable to use the SET CONTAINER statement.

C. It fails because local users are unable to use the SET CONTAINER statement.

D. If fails because the SET CONTAINER statement cannot be used with PDB$SEED as the target pluggable database (PDB).

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.

You are connected to a pluggable database (PDB) as a common user with DBA privileges.The STATISTICS_LEVEL parameter is PDB_MODIFIABLE. You execute the following:SQL > ALTER SYSTEM SET STATISTICS_LEVEL = ALL SID = ‘*’ SCOPE = SPFILE;Which is true about the result of this command?（）

A. The STATISTICS_LEVEL parameter is set to all whenever this PDB is re-opened.

B. The STATISTICS_LEVEL parameter is set to ALL whenever any PDB is reopened.

C. The STATISTICS_LEVEL parameter is set to all whenever the multitenant container database (CDB) is restarted.

D. Nothing happens; because there is no SPFILE for each PDB, the statement is ignored.

Your multitenant container database, CDB1, is running in ARCHIVELOG mode and has two pluggable databases, HR_PDB and ACCOUNTS_PDB. An RMAN backup exists for the database.You issue the command to open ACCOUNTS_PDB and find that the USERDATA.DBF data file for the default permanent tablespace USERDATA belonging to ACCOUNTS_PDB is corrupted.What should you do before executing the commands to restore and recover the data file in ACCOUNTS_PDB?（）

A. Place CDB1 in the mount stage and then the USERDATA tablespace offline in ACCOUNTS_PDb.

B. Place CDB1 in the mount stage and issue the ALTER PLUGGABLE DATABASE accounts_pdb CLOSE IMMEDIATE command.

C. Issue the ALTER PLUGGABLE DATABASE accounts_pdb RESTRICTED command.

D. Take the USERDATA tablespace offline in ACCOUNTS_PDb.
