To succeed in the Oracle 1Z0-083 certification exam, candidates must have a strong understanding of database architecture, SQL, and PL/SQL. They should also be familiar with Oracle database management tools, such as Oracle Enterprise Manager and SQL*Plus. Additionally, candidates should have practical experience in administering Oracle databases, as the exam will test their ability to apply theoretical knowledge in real-world scenarios.

NO.36 HR_ROOT is an application container with the HR_APP application installed. No application PDBs and no application seed have yet been created in HR_ROOT. An application PDB, PDB1,must be created so that the HR_APP application’s common objects are accessible to it. Which two methods can be used?

Create the PDB1 application PDB and synchronize it with poB$SEED.

Create the PDB1 application PDB and synchronize it with HR_ROOT.

Create the PDB1 application PDB and install HR_APP in it.

Create an application seed, and install HR_APP in it.

Create an application seed, synchronize it with HR_ROOT, and then create the PDB1.application PDB.

NO.37 A database is configured in ARCHIVE LOG mode. A full RMAN backup exists but no control file backup to trace has been taken. A media failure has occurred. In which two scenarios is incomplete recovery required? (Choose two.)

after losing a SYSAUX tablespace data file

after losing an UNDO tablespace that is in use

NO.38 Which two are true about Oracle instance recovery? (Choose three.)

Recovery begins from the beginning of the CURRENT redo log group.

Recovery begins from the last checkpoint position that was calculated by the Database Writer before instance failure.

Recovery begins from the start of any ACTIVE redo log group or the start of the CURRENT log group if no other group is ACTIVE.

Recovery reads redo until the end of the redo thread. SMON rolls back any dead transactions, and then the datanase is opened.

Recovery begins from the last checkpoint position that was recorded in the control file by the checkpoint process (CKPT).

2,4,5

1,3,4,5

NO.42 Choose three. Which three are true about SGA memory management in a multitenant database?

SGA_MIN_SIZE cannot be set for a PDB.

Setting SHARED_POOL_SIZE for a PDB guarantees a minimum amount of Shared Pool memory for that PDB.

Setting SGA_TARGET for a PDB guarantees a minimum amount of SGA memory for that PDB.

The SHARED_POOL_SIZE setting for a PDB can be up to 80% of the SHARED_POOL_SIZE setting of the root container.

Setting DB_CACHE_SIZE for a PDB guarantees a minimum amount of Database Buffer Cache memory for that PDB.

The SGA_TARGET setting for a PDB cannot exceed 50% of the SGA_TARGET value of the root container.

NO.43 You have configured RMAN SBT channels to write backups to media.
You then take an RMAN backup by using this command:

Which three are true?

All archive logs created after this backup are kept for two years.

The data file backups in the self-contained archive backup are not considered obsolete for two years regardless of the retention policy.

The restore point is a label for the system change number (SCN) that will be saved two years after the archival backup was taken.

The control file is included in the self-contained archival backup.

The spfile is included in the self-contained archival backup.

The restore point is a label for the system change number (SCN) before the archival backup was taken.

NO.44 Choose three. Which three are true about upgrading an application in an application container?

An application root clone gets created automatically.

The upgrade can be performed when connected either to CDB$ROOT or to PDB$SEED.

After an application upgrade, the application container’s PDBs remain synchronized with the existing application root.

The upgrade must be performed when connected to CDB$ROOT.

An application name and version number must be specified to upgrade the application.

After an application upgrade, the application container’s PDBs are automatically synchronized with the application root clone.

NO.45 You execute the following piece of code with appropriate privileges: BEGIN DBMS_REDACT.ADD_POLICY ( END; object_schema object_name column_name policy_name function_type expression => ‘SCOTT’, => ‘EMP’, => ‘SAL’, => ‘SCOTT_EMP’, => DBMS_REDACT.FULL, => ‘SYS_CONTEXT (”SYS_SESSION_ROLES”,”MGR”) = ”FALSE”’); END; BEGIN DBMS_REDACT.ADD_POLICY ( object_schema object_name column_name policy_name function_type expression => ‘SCOTT’, => ‘EMP_VW’, => ‘SAL’, => ‘SCOTT_EMP_VW’, => DBMS_REDACT.NONE, => ‘SYS_CONTEXT (”SYS_SESSION_ROLES”,”MGR”) = ”FALSE”’); User SCOTT has been granted the CREATE SESSION privilege and the MGR role. Which two statements are true when a session logged in as SCOTT queries the SAL column in the view and the table?

NO.46 You notice that the performance of your production 24/7 Oracle 12c database has significantly degraded. Sometimes you are not able to connect to the instance because it hangs. You do not want to restart the database instance. How can you detect the cause of the degraded performance?

Enable Memory Access Mode, which reads performance data from SGA.

Use emergency monitoring to fetch data directly from SGA for analysis.

Run Automatic Database Diagnostic Monitor (ADDM) to fetch information from the latest Automatic Workload Repository (AWR) snapshots.
