Q116. Which two are true about instance recovery? (Choose two.)

It is not possible if an archived log is missing.

It is performed automatically after the database is opened; however, blocks requiring recovery are not available until they are recovered.

Setting FAST_START_MTTR_TARGET to a lower value reduces instance recovery time by causing dirty buffers to be written to disk more frequently, thereby reducing the number of I/Os needed during instance recovery.

It is performed by the Recovery Writer (RVWR) background process.

Setting FAST_START_MTTR_TARGET to a higher value reduces instance recovery time by causing The log writer to write more frquently, thereby reducing the number of I/Os needed during instance recovery.

It is performed automatically while the database remains in MOUNT state. Then the database is opened.

It removes the AUDSYS schema and the AUDIT_ADMIN and AUDIT_VIEWER roles

It increases tablespace size, if required, to meet upgrade requirements.

Q118. Which two are true about diagnosing Oracle Database failure situations using Data Recovery Advisor? (Choose two.)

Using the Data Recovery Advisor LIST FAILURE command always requires that the database for which failures are to be listed is in MOUNT state.

A failure can be closed only when it has been repaired.

Data Recovery Advisor can be used if a database is closed.

The Data Recovery Advisor CHANGE FAILURE command can be used only to change failure priorities.

Data Recovery Advisor can proactively check for failures.

Q119. 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? (Choose three.)

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

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

The SPFILEis included in the self-contaied archival backup.

The control file 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.

By default, members of the OSASM group can access Automatic Storage Management and RDBMS instances.

The primary group for the Oracle Grid Infrastructure and Oracle Database owners must be the Oracle Inventory group.

The Oracle Grid Infrastructure installation must be owned by the grid user.

The Oracle Grid Infrastructure owner owns Oracle Restart and Oracle Automatic Storage Management binaries.

The Oracle Grid Infrastructure owner must have OSOPER, OSBACKUPDBA, and OSKMDBA as secondary groups.

The same OSDBA group must be used for Automatic Storage Management and the Oracle Database.

Q124. Choose two. Which two are true in Oracle 19c and later releases?

Schema Only accounts can be granted administrator privileges.

If the password file location changes, then the instance must be restarted.

Unified Auditing can be configured to audit only events that are issued directly by an audited user.

All the Oracle-supplied accounts are Schema Only accounts.

Unified Auditing can be configured to audit only events that are issued indirectly by all users

Q125. Choose the best answer. Examine this configuration: 1. CDB1 is an Oracle Database 12c Release 2 container database (CDB). 2. PDB1 and PDB2 are two pluggable databases (PDBs) in CDB1. After successfully performing all the preupgrade tasks, you execute these commands from the Oracle Database 18c environment: $ export ORACLE_SID=cdb1 $ sqlplus / as sysdba SQL> STARTUP UPGRADE; SQL> SHOW pdbs CON_ID CON_NAME OPEN MODE RESTRICTED —————————————————————2 PDB$SEED 3 PDB1 4 PDB2 MIGRATE YES MOUNTED YES MOUNTED YES SQL> ALTER PLUGGABLE DATABASE pdb1 OPEN UPGRADE; Pluggable database altered. SQL> exit $ $ORACLE_HOME/perl/bin/perl catctl.pl -C ‘PDB2’ What is the outcome?

It fails because PDB$SEED is in MIGRATE state.

Only CDB$ROOT, PDB$SEED, and PDB1 are upgraded.

Only CDB$ROOT, PDB$SEED, and PDB2 are upgraded.

It fails because PDB2 is not in UPGRADE state.

CDB$ROOT, PDB$SEED, PDB1, and PDB2 are upgraded.

Only CDB$ROOT and PDB$SEED are upgraded.

Q126. Application PDBs, SALES_APP1 and SALES_APP2, must be created and they must access common tables of the SALES APP application. Examine these steps:
Install the SALES_APP application, induding the common tables, in the application root.
Install the SALES_APP application in the application root and the common tables in both the CDB root and the application root.
Create an application seed.
Install the SALES_APP application in the application seed.
Create the SALES_APP1 and SALES_APP2 application PDBs.
Sync the SALES_APP1 and SALES_APP2 application PDBs with the application root.
Sync the SALES_APP1 and SALES_APP2 application PDBs with the application seed.
Sync the application seed with the application root. Which are the minimum required steps in the correct sequence?
