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.

D. It fails and reports an error because the CONTAINER=CURRENT clause is not specified in the command.

E. It executes successfully but neither tablespace nor the data file is created.

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.

In your multitenant container database (CDB) containing pluggable databases (PDB), users complain about performance degradation.How does real-time Automatic database Diagnostic Monitor (ADDM) check performance degradation and provide solutions？（）

A. It collects data from SGA and compares it with a preserved snapshot.

B. It collects data from SGA, analyzes it, and provides a report.

C. It collects data from SGA and compares it with the latest snapshot.

D. It collects data from both SGA and PGA, analyzes it, and provides a report

A. The CDB must be open.

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.

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

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 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

C.10，1，2，5，4，9，8

D.10，1，5，8，10

You upgraded your database from pre-12c to a multitenant container database (CDB) containing pluggable databases (PDBs).Examine the query and its output:Which two tasks must you perform to add users with SYSBACKUP, SYSDG, and SYSKM privilege to the password file？（）

A. Assign the appropriate operating system groups to SYSBACKUP, SYSDG, SYSKM.

B. Grant SYSBACKUP, SYSDG, and SYSKM privileges to the intended users.

C. Re-create the password file with SYSBACKUP, SYSDG, and SYSKM privilege and the FORCE argument set to No.

D. Re-create the password file with SYSBACKUP, SYSDG, and SYSKM privilege, and FORCE arguments set to Yes.

E. Re-create the password file in the Oracle Database 12c format.

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. You execute thefollowing command from the root container:SQL >REVOKE create table FROM C A_ADMIN;What is the result？（）

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.

Flashback is enabled for your multitenant container database (CDB), which contains two pluggable database (PDBs). A local user was accidently dropped from one of the PDBs.You want to flash back the PDB to the time before the local user was dropped. 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

In your multitenant container database (CDB) containing pluggable database (PDBs), the HR user executes the following commands to create and grant privileges on a procedure:CREATE OR REPLACE PROCEDURE create_test_v (v_emp_id NUMBER, v_ename VARCHAR2,v_SALARY NUMBER, v_dept_id NUMBER)BEGININSERT INTO hr.test VALUES (V_emp_id, V_ename, V_salary, V_dept_id);END;/GRANT EXECUTE ON CREATE_TEST TO john, jim, smith, king;How can you prevent users having the EXECUTE privilege on the CREATE_TEST procedure from inserting values into tables on which they do not have any privileges？（）

A. Create the CREATE_TEST procedure with definer’s rights.

B. Grant the EXECUTE privilege to users with GRANT OPTION on the CREATE_TEST procedure.

C. Create the CREATE_TEST procedure with invoker’s rights.

D. Create the CREATE_TEST procedure as part of a package and grant users the EXECUTE privilege the package.
