NO.2 Identify three valid options for adding a pluggable database (PDB) to an existing multitenant
container database
(CDB).
A. Use the DBMS_PDB package to plug an Oracle 11 g Release 2 (11.2.0.3.0) non-CDB database into
an existing CDB.
B. Use the CREATE PLUGGABLE DATABASE statement to create a PDB using the files from the SEED.
C. Use the CREATE DATABASE . . . ENABLE PLUGGABLE DATABASE statement to provision a PDB by
copying file from
the SEED.
D. Use the DBMS_PDB package to clone an existing PDB.
E. Use the DBMS_PDB package to plug an Oracle 12c non-CDB database into an existing CDB.
Answer: B,D,E
Explanation:
Use the CREATE PLUGGABLE DATABASE statement to create a pluggable database (PDB).
This statement enables you to perform the following tasks:
* (A) Create a PDB by using the seed as a template
Use the create_pdb_from_seed clause to create a PDB by using the seed in the multitenant container
database (CDB)
as a template. The files associated with the seed are copied to a new location and the copied files are
then associated
with the new PDB.
* (C) Create a PDB by cloning an existing PDB
Use the create_pdb_clone clause to create a PDB by copying an existing PDB (the source PDB) and
then plugging the
copy into the CDB. The files associated with the source PDB are copied to a new location and the
copied files are
associated with the new PDB. This operation is called cloning a PDB.
The source PDB can be plugged in or unplugged. If plugged in, then the source PDB can be in the
same CDB or in a
remote CDB. If the source PDB is in a remote CDB, then a database link is used to connect to the
remote CDB and copy
the files.
* Create a PDB by plugging an unplugged PDB or a non-CDB into a CDB
Use the create_pdb_from_xml clause to plug an unplugged PDB or a non-CDB into a CDB, using an
XML metadata file.

NO.3 Which two statements are true concerning the Resource Manager plans for individual
pluggable databases (PDB
plans) in a multitenant container database (CDB)?
A. If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups
across all PDBs
in the CDB.
B. If no PDB plan is enabled for a pluggable database, then the PDB share in the CDB plan is
dynamically calculated.
C. In a PDB plan, subplans may be used with up to eight consumer groups.
D. If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups
based on the
shares provided to the PDB in the CDB plan and the shares provided to the consumer groups in the
PDB plan.
E. If no PDB plan is enabled for a pluggable database, then all sessions for that PDB are treated to an
equal degree of
the resource share of that PDB.
Answer: D,E
Explanation:
A: Setting a PDB resource plan is optional. If not specified, all sessions within the PDB are treated
equally.
*
In a non-CDB database, workloads within a database are managed with resource plans.
In a PDB, workloads are also managed with resource plans, also called PDB resource plans.
The functionality is similar except for the following differences:
/ Non-CDB Database
Multi-level resource plans
Up to 32 consumer groups
Subplans
/ PDB Database
Single-level resource plans only
Up to 8 consumer groups
(not B) No subplans

NO.4 Your database is running in NOARCHIVING mode.
Examine the following parameters:
You execute the following command after performing a STARTUP MOUNT:
SQL> ALTER DATABASE ARCHIVELOG;
Which statement is true about the execution of the command?
A. It executes successfully and issues a warning to set LOG_ARCHIVE_DEST while opening the
database.
B. It executes successfully and sets the Fast Recovery Area as the local archive destination.
C. It fails and returns an error about LOG_ARCHIVE_DEST not being set.
D. It executes successfully and sets $ORACLE_HOME/dbs as the default archive destination.
Answer: C
