Actual Oracle 1Z0-083 Exam Questions

Question 1

Which three are true about managing memory components in an Oracle database instance? (Choose three.)

AWith Automatic Shared Memory Management, the database instance can increase the Large Pool size by reducing the Shared Pool size.

BWith Automatic Memory Management, the database instance can increase the System Global Area size by reducing the Program Global Area size.

CAutomatically tuned and resized System Global Area components will always revert to their initial sizes after an instance restart.

DAutomatic Memory Management must be used together with locking the System Global Area into physical memory.

EWith Automatic Shared Memory Management, the database instance can increase the Program Global Area size by reducing the System Global Area size.

FOn Line Transaction Processing systems often use less Program Global Area than Decision Support Systems.

Correct answer: A, B, F

Question 2

CDB1 is a container database.

PDB1 and PDB2 are pluggable databases in CDB1.

You execute these commands successfully:

Which two are true? (Choose two.)

APDB1 and PDB2 are in MOUNT state.

BRedo logs are opened.

CPDB1 and PDB2 are in READ ONLY state.

DCDB$ROOT is in MOUNT state.

EPDB$SEED is in READ ONLY state.

Correct answer: B, E

Question 3

A database is configured in ARCHIVELOG mode.

Full RMAN backups are taken and no backup to trace has been taken of the control file. A media failure has occurred.

In which two scenarios is complete recovery possible? (Choose two.)

Awhen any archived log from, before, or after the most recent backup is corrupt.

Bafter losing all copies of the control file

Cafter losing an archived log from after the most recent backup

HBlocks from multiple data files can be contained in one backup set,

Correct answer: B, E, F, H

Question 5

A container database called CDB1 is OMF-enabled.

PDB_FILE_NAME_CONVERT is not configured in CDB1. PDB1 was unplugged from CDB1 earlier in the week. Examine this command, which will be executed in CDB1:

CREATE PLUGGABLE DATABASE pdb1

USING '/u01/app/oracle/oradata/pdb1.xml'

SOURCE_FILE_NAME_CONVERT =

('/u01/app/oracle/oradata/', '/u02/app/oracle/oradata/');

Which two are true? (Choose two.)

APDB1 data files already exist in the correct location.

BDBMS_PDB.CHECK_PLUG_COMPATIBILITY must be run in CDB1 before executing the command.

CPDB_FILE_NAME_CONVERT must be set before executing the command.

D/u01/app/oracle/oradata/pdb1.xml does not contain the current locations of data files for PDB1.

EPDB1 must be dropped from CDB1.

Correct answer: A, E
