Question 21

Which two statements are true about variable extent size support for large ASM files?

A.The metadata used to track extents in SGA is reduced.

B.Rebalance operations are completed faster than with a fixed extent size

C.An ASM Instance automatically allocates an appropriate extent size.

D.Resync operations are completed faster when a disk comes online after being taken offline.

E.Performance improves in a stretch cluster configuration by reading from a local copy of an extent.

Question 22

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

C.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.

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

E.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.

Question 23

You are connected using SQL* Plus to a multitenant container database (CDB) with SYSDBA privileges and execute the following sequence statements:

What is the result of the last SET CONTAINER statement and why is it so?

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

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

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

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

Question 24

Which two statements are true about the Database Configuration Assistant (DBCA)?
(Choose two.)

A.It can be used to create a database template from an existing database.

B.It can be used to add a new tablespace.

C.It can generate SQL database creation scripts.

D.It can be used to copy an existing Oracle database to a new host and apply any patches necessary in the new host.

E.It can configure Automatic Storage Management (ASM) diskgroups.

Question 25

The HR user owns the BONUSES table. HR grants privileges to the user TOM by using the command:
SQL> GRANT SELECT ON bonuses TO tom WITH GRANT OPTION;
TOM then executes this command to grant privileges to the user JIM:
SQL> GRANT SELET ON hr.bonuses TO jim;
Which statement is true?

A.JIMcan grant theSELECT ON HR.BONUSESprivilege to other users, but cannot revoke the privilege from them.

B.TOMcannot revoke theSELECT ON HR.BONUSESprivilege fromJIM.

C.HRcan revoke theSELECT ON HR.BONUSESprivilege fromTOM, which will
automatically revoke theSELECT ON HR.BONUSESprivilege fromJIM.

D.HRcan revoke theSELECT ON HR.BINUSESprivilege fromJIM.
