• B. An application PDB can belong to multiple application containers.
• C. An application root can be unplugged from a CDB and plugged in to another CD

• E. User-created common objects are accessible from the CDB root.
• F. Multiple application roots can be created in one container database.

The EMP_CDB1 and EMP_CDB2 CDBs are in ARCHIVELOG mode.
Oracle Managed Files is enabled in both CDBs.
EMP_CDB1 has a PDB, EMP_PDB1.
In EMP_CDB2, you log in as the SYS user.
You plan to execute this statement:
CREATE PLUGGABLE DATABASE emp_pdb2 FROM emp_pdb1@emp_link RELOCATE;
Which two statements are true? (Choose two.)

• A. The AVAILABILITY MAX clause should be added to the command to ensure transaction consistency during the relocation process.
• B. SYSOPER privilege should be granted to the user defined in EMP_LINK and used to connect to the remote database.
• C. EMP_LINK should exist as a public link in EMP_CDB1 and EMP_CDB2.
• D. EMP_PDB1 should be dropped manually from EMP_CDB1 after executing the relocating command.
• E. Only EMP_PDB1 should be in local undo mode.
• F. EMP_PDB2 should be opened in read-write mode to complete the relocation process.

USER1 is an OS user with the password oracle and is only a member of the oinstall group.
In the ORCL database, the OS_AUTHEN_PREFIX value is ops$.
Examine these commands executed by the DBA:
SQL> CREATE USER ops$user1 IDENTIFIED externally;
SQL> GRANT create session TO ops$user1;
How can USER1 be given the SYSRAC privilege?

• A. Grant SYSDBA to ops$user1
• B. Grant SYSRAC to user1.
• C. Make USER1 a member of the OSRACDBA group in Linux or the ORA_%HOMENAME%_SYSRAC group in Windows.
• D. Grant SYSRAC to ops$user1.
• E. Make User1 a member of the OSDBA group in Linux or the ORA_%HOMENAME%_SYSDBA group in Windows only.

You create a new application container, SALES_APP, with application PDBs, SALES1_PDB, and SALES2_PDB.
You want to install the NEW_APP application in SALES1_PDB and SALES2_PDB by using:

Where should you execute these statements?

• A. BEGIN/END INSTALL statements should be executed in the CDB root and the SYNC statement in the application root.
• B. All the statements should be executed in the application seed.
• C. BEGIN/END INSTALL statements should be executed in the application root and the SYNC statement in SALES1_PDB and SALES2_PDB.
• D. All the statements should be executed in the application root.
• E. All the statements should be executed in the SALES1_PDB and SALES2_PDB application containers.
