Question 187

Examine the command:
SQL> CREATE TABLESPACE test1
DATAFILE '/u01/app/oracle/oradata/orc1/test01.dbf' SIZE 5M
AUTOEXTEND ON UNIFORM;
Which statement is true?

A.Allocated and free extents are tracked using bitmaps.

B.The data file, TEST01.DBF, can be auto extended to a maximum size of 5M.

C.Segment free space is tracked in the data dictionary.

D.The tablespace, TEST1, can contain a maximum of one data file.

Question 188

A database is stored in an Automatic Storage Management (ASM) disk group, disk group, DGROUP1 with SQL:

There is enough free space in the disk group for mirroring to be done.
What happens if the CONTROLLER1 failure group becomes unavailable due to error of for maintenance?

A.Transactions and queries accessing database objects contained in any tablespace stored in DGROUP1 will fall.

B.Mirroring of allocation units will be done to ASM disks in the CONTROLLER2 failure group until the CONTROLLER1 for failure group is brought back online.

C.The data in the CONTROLLER1 failure group is copied to the controller2 failure group and rebalancing is initiated.

D.ASM does not mirror any data until the controller failure group is brought back online, and newly allocated primary allocation units (AU) are stored in the controller2 failure group, without mirroring.

E.Transactions accessing database objects contained in any tablespace stored in DGROUP1 will fail but queries will succeed.

Question 189

In your multitenant container database (CDB) containing same pluggable databases (PDBs), you execute the following commands in the root container:

Which two statements are true? (Choose two.)

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.

Question 190

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.
