NEW QUESTION 91
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.

NEW QUESTION 92
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.

RMAN uses the push method to transfer image copies

RMAN uses the push method to transfer backup sets

RMAN uses the pull method to restore files using backup sets

NEW QUESTION 94
Which two are true about various Oracle security and auditing capabilities?

Application-common OLS policies can be created in an application root inside an install/patch BEGIN-END block.

Application-common TSDP policies are always container specific.

Fine-grained auditing (FGA) policies in an application root are automatically synchronized to all application PDBs contained in the application container.

Unified auditing can be automatically synchronized to all application PDBs in an application container.

Application-common Transparent Security Data Protection (TSDP) policies can be created only within an application install/patch begin-end block.

NEW QUESTION 95
Your SALES_ROOTapplication container has two application PDBs.
The SALES_APPapplication has a common table, FIN.REVENUE, in the two PDBs.
Examine this query and its output:

Which two are true? (Choose two.)

The CONTAINERS clause cannot be used in queries on the REVENUE table.

The REVENUE table must be a list-partitioned table.

The MAPTABLE tables defines a logical partition key on a commonly used column for the REVENUE table.

The MAPTABLE table is a metadata-linked table.

A container map exists for the REVENUE table, but is not enabled.

The REVENUE table partitions are not pruned across the PDBs automatically.

Tested in lab with exact same setting like in the output shown.
A). -> incorrect – The CONTAINERS clause can be used.
B). -> incorrect – It can be also a range based.
C). -> CORRECT – https://docs.oracle.com/en/database/oracle/oracle-database/19/multi/administering-application-containers-with-sql-plus.html#GUID-AAF93A02-7C70-4024-8758-E351C213543E
D). -> incorrect – Regular table
E). -> incorrect – shown in the output CONTAINER_MAP = YES
F). -> CORRECT – because CONTAINERS_DEFAULT is not enabled for the revenue table.

All users have their default set of system privileges.
For which three situations will data not be redacted? (Choose three.)

SYS sessions, regardless of the roles that are set in the session

SYSTEM sessions, regardless of the roles that are set in the session

SCOTT sessions, only if the MGR role is set in the session

SCOTT sessions, only if the MGR role is granted to SCOTT

SCOTT sessions, because he is the owner of the table

SYSTEM session, only if the MGR role is set in the session

NEW QUESTION 100
Which three are true about block media recovery? (Choose three.)

The data file containing the block being recovered remains online.

To use it, Flashback Database must be enabled.

A block being recovered is not accessible.

It can be performed on noncorrupt blocks.

The target database for which one or more blocks are to be recovered must be in the OPEN state.

It cannot repair logical corruption.

NEW QUESTION 101
How do you configure a CDB for local undo mode?

Open the CDB instance in upgrade mode. In CDB$ROOT, execute ALTER DATABASE LOCAL UNDO ON, and then restart the CDB instance.

Open the CDB instance in restricted mode. In CDB$ROOT, execute ALTER DATABASE LOCAL UNDO ON, and create an UNDO tablespace in each PDB, then restart the CDB instance.

Open the CDB instance in restricted mode. In CDB$ROOT, drop the UNDO tablespace. Execute ALTER DATABASE LOCAL UNDO ON in each PDB, and then restart the CDB instance.

Open the CDB instance in read-only mode. In CDB$ROOT, execute ALTER DATABASE LOCAL UNDO ON, and then change the CDB to read/write mode.

Open the CDB instance in upgrade mode. In each PDB, execute ALTER DATABASE LOCAL UNDO ON, create an UNDO tablespace, and then restart the CDB instance.

NEW QUESTION 102
Examine the command for creating pluggable database PDB2 in container database CDB2.

Select three options, any one of which is required for it to execute successfully. (Choose three.)

Add the FILE_NAME_CONVERT clause to the statement and set the
PDB_FILE_NAME_CONVERT parameter.

Add only the CREATE_FILE_DEST clause to the statement.

Set only the PDB_FILE_NAME_CONVERT parameter.

Set the PDB_FILE_NAME_CONVERT parameter and enable OMF.

Enable only OMF.

Add the FILE_NAME_CONVERT clause to the statement and enable Oracle Managed Files (OMF)

You can specify FILE_NAME_CONVERT = NONE, which is the same as omitting this clause. If you omit this clause, then the database first attempts to use Oracle Managed Files to generate file names. If you are not using Oracle Managed Files, then the database uses the PDB_FILE_NAME_CONVERT initialization parameter to generate file names. If this parameter is not set, then an error occurs.

NEW QUESTION 106
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.

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.
