You connect to the CDB and execute the following commands: SQL > SHUTDOWN IMMEDIATE SQL > STARTUP MOUNT SQL > FLASHBACK DATABASE to TIME “TO_DATE (‘08/20/12’ , ‘MM/DD/YY’)”; Examine following commands: 1. ALTER PLUGGABLE DATABASE ALL OPEN; 2. ALTER DATABASE OPEN; 3. ALTER DATABASE OPEN RESETLOGS; Which command or commands should you execute next to allow updates to the flashback back schema?（）

• A、Only 1
• B、Only 2
• C、Only 3
• D、3 and 1
• E、1 and 2

• B、The CDB must be in the mount stage.
• C、The CDB must be in the nomount stage.
• D、Alt existing PDBs must be closed.

第14题：

You conned using SQL Plus to the root container of a multitenant container database (CDB) with SYSDBA privilege. The CDB has several pluggable databases (PDBs) open in the read/write mode. There are ongoing transactions in both the CDB and PDBs. What happens alter issuing the SHUTDOWN TRANSACTIONAL statement?（）

• A、The shutdown proceeds immediately. The shutdown proceeds as soon as all transactions in the PDBs are either committed or rolledhack.
• B、The shutdown proceeds as soon as all transactions in the CDB are either committed or rolled back.
• C、The shutdown proceeds as soon as all transactions in both the CDB and PDBs are either committed or rolled back.
• D、The statement results in an error because there are open PDBs.

第15题：

Your multitenant container database (CDB) is running in ARCHIVELOG mode. You connect to the CDB RMAN. Examine the following command and its output: You execute the following command: RMAN > BACKUP DATABASE PLUS ARCHIVELOG; Which data files will be backed up?（）

• A、Data files that belong to only the root container
• B、Data files that belong to the root container and all the pluggable databases (PDBs)
• C、Data files that belong to only the root container and PDB$SEED
• D、Data files that belong to the root container and all the PDBs excluding PDB$SEED

第16题：

In your multitenant container database (CDB) containing pluggable database (PDBs), you granted theCREATE TABLE privilege to the common user C # # A_ADMIN in root and all PDBs.

• A、It executes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in root only.
• B、It fails and reports an error because the CONTAINER=ALL clause is not used.
• C、It excludes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in root and all PDBs.
• D、It fails and reports an error because the CONTAINER=CURRENT clause is not used.
• E、It executes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in all PDBs.

Your multitenant container database (CDB) contains pluggable databases (PDBs), you are connected to the HR_PDB. You execute the following command: SQL > CREATE UNDO TABLESPACE undotb01 DATAFILE ‘u01/oracle/rddb1/undotbs01.dbf’ SIZE 60M AUTOEXTEND ON; What is the result?（）

• A、It executes successfully and creates an UNDO tablespace in hr_pdb.
• B、It falls and reports an error because there can be only one undo tablespace in a cdb.
• C、It fails and reports an error because the CONTAINER=ALL clause is not specified in the command.
