Question 3:
What is the effect of specifying the “ENABLE PLUGGABLE DATABASE” clause in a “CREATE DATABASE” statement?
A. It will create a multitenant container database (CDB) with only the root opened.
B. It will create a CDB with root opened and seed read-only.
C. It will create a CDB with root and seed opened and one PDB mounted.
D. It will create a CDB that must be plugged into an existing CDB.
E. It will create a CDB with root opened and seed mounted.
Correct Answer: B
Question 4:

A. mounting disk groups
B. managing Allocation Units (AUs) for disk group content
C. managing extent allocation for Oracle database segments
D. acting as an I/O server to write data file blocks to ASM disks on behalf of Database Writer processes (DBWn)

Correct Answer: ABE
Reference: https://docs.oracle.com/cd/E11882_01/server.112/e18951/asmcon.htm#OSTMG94057
Question 5:
RMAN is connected to a target database instance and an auxiliary instance. You execute 3625the command:
RMAN> DUPLICATE TARGET DATABASE TO dupdb FROM ACTIVE DATABASE SECTION SIZE 1G; What is the outcome?
A. RMAN uses the pull method to restore files using image copies
B. RMAN uses the push method to transfer image copies
C. RMAN uses the push method to transfer backup sets
D. RMAN uses the pull method to restore files using backup sets
Correct Answer: D
When RMAN performs active database duplication using backup sets, a connection is established between the source database and the auxiliary database. The auxiliary database then connects to the source database through Oracle Net Services and retrieves the required database files from the source database. This method of active database duplication is also to as the pull-based method.
Example: DUPLICATE TARGET DATABASE TO duped FROM ACTIVE DATABASE PASSWORD FILE SPFILE NOFILENAMECHECK; Incorrect Answers: A, B, C: When active database duplication is performed using image copies after RMAN establishes a connection with the source database, the source database transfers the required database files to the auxiliary database. Using image copies may require additional resources on the source database. This method is referred to as the push-based method of active database duplication.

Question 6:
The HR_ROOT application container must support the execution of a query on a table shared by application local PDBs PDB1 and PDB2, and remote PDB PDB3. Which three are true? (Choose three.)
A. A proxy PDB must exist in the application root in the remote CDB.
B. A database link must exist in the local CDB root referring to the remote CDB.
C. PDB3\’s application root replica must exist in the local CDB.
D. A database link must exist in the remote CDB referring to the local CDB.
E. The HR_ROOT replica must exist in the remote CDB.
F. A proxy PDB must exist in the application root in the local CDB.
Correct Answer: BEF
Database link must be created in master application root (local CDB) referring to replica application root (remote CDB). Option B Proxy PDB must be created in the master application root (local CDB) using this database link. Option F Replica application root must exist in remote CDB (created or upgraded using SYNC in local Proxy PDB). Option E With this, we can make a SELECT that will show data from local and remote PDB applications (Query in local master application root using CONTAINERS clause).
Question 7:
Examine this extract from the show parameters command:
How are System Global Area (SGA) and Program Global Area (PGA) memory managed by an instance using these parameter settings?
A. SGA and PGA memory are manually managed
B. SGA memory is manually managed and PGA memory is managed by using Automated SQL Execution Memory Management
C. SGA memory is managed by using Automatic Shared Memory Management (ASMM) and PGA memory is manually managed
D. SGA memory is managed by using Automatic Shared Memory Management (ASMM) and PGA memory is managed by using Automated SQL Execution Memory Management
E. SGA and PGA memory are managed by using Automatic Memory Management (AMM)
Correct Answer: E
The simplest way to manage instance memory is to allow the Oracle Database instance to automatically manage and tune it for you. To do so (on most platforms), you set only a target memory size initialization parameter
(MEMORY_TARGET) and optionally a maximum memory size initialization parameter (MEMORY_MAX_TARGET).
You can omit the statements that set the SGA_TARGET and PGA_AGGREGATE_TARGET parameter values to zero and leave either or both of the values as positive numbers. In this case, the values act as minimum values for the sizes of
the SGA or instance PGA.
In addition, you can use the PGA_AGGREGATE_LIMIT initialization parameter to set an instance-wide hard limit for PGA memory. You can set PGA_AGGREGATE_LIMIT whether or not you use automatic memory management. See “Using
Automatic PGA Memory Management”.
Question 8:
Which three are true In Oracle 19c and later releases?
A. Tablespaces always remain In read/write mode during transportable tablespace operations.
B. Simultaneous data pump jobs can be limited at the pluggable database (PDB) level.
C. Tablespaces never remain In read/write mode during transportable tablespace operations.
D. An ordinary data pump export of a table with encrypted columns will always encrypt the same columns when imported.
E. A transportable data pump import can leave a plugged-in tablespace in read-only mode.
F. A transportable data pump import can leave a plugged-in tablespace In read/write mode.
Correct Answer: BCD
This is a new feature in 19c and the latest https://docs.oracle.com/en/database/oracle/oracle-database/19/newft/new-features.html#GUID-8BAADCB7-F93A-48D0-BF24-369C4947C56B
“You can now import tablespace files mounted on two different databases as long as the files are set as read-only.” You can set read/only, so it’s not mandatory.
D is also correct for the MAX_DATAPUMP_JOBS_PER_PBD parameter
Question 9:
Which two are true about data movement between a non-CDB and a PDB using a Data Pump? (Choose two.)
A. Tablespaces are automatically created as needed while importing full exports in either a non-CDB or a PDB.
B. Oracle attempts to convert conventional database users to local users when moving schemas from a non-CDB to a PDB.
C. A new PDB is automatically created when importing a non-CDB into a CDB.
D. Oracle attempts to convert common users to conventional users when moving schemas from a PDB to a non-CDB.
E. Moving data from a PDB to a non-CDB is only possible by using transportable tablespace export and import.
F. Moving data from a non-CDB to a PDB is only possible by using conventional export and import.
Correct Answer: BD
E, F ->Incorrect -> tablespace export/import can be conventional or transportable A, C -> Nothing is created automatically you must create what you need.
Question 10:
Which four are true about a Recovery Manager (RMAN) duplication without a TARGET connection? (Choose four.)
A. The NOREDO clause must be used if the backups of the database being duplicated were taken when the database was in NOARCHIVELOG mode.
B. The UNDO TABLESPACE clause is always required when no connection exists to the TARGET instance.
C. RMAN “pushes” the backups of the database to be duplicated over the network to the auxiliary instance.
D. The NOREDO clause can be used if the backups of the database being duplicated were taken when the database was in ARCHIVELOG mode.
E. RMAN SBT-based backups of the database to be duplicated can be used by the auxiliary instance.
F. The UNDO TABLESPACE clause is always required when no connection exists to the recovery catalog and the TARGET database is closed.
G. The UNDO TABLESPACE clause is always required when no connection exists to the recovery catalog and the TARGET database is opened.
H. RMAN disk-based backups of the database to be duplicated can be used by the auxiliary instance.
Correct Answer: ADEH

C. default section size for backups
D. default destinations for backups
E. multiple backup device types for a single backup

Question 13:

A. Decreasing PCTUSED
B. Decreasing PCTFREE
C. Increasing the number of DBWN process
D. Using Automatic Segment Space Management (ASSM)
E. Increasing db_buffer_cache based on the V$DB_CACHE_ADVICE recommendation
