（A）shared UNDO and default database temporary tablespace

（B）local users and local roles

（C）local temporary tablespaces

（D）Oracle-supplied metadata

（E）CDB views providing information across PDBs

（F）application tablespaces

（G）shared Oracle-supplied data

（H）non-shared local metadata

（A）control_files

（B）maxdatafiles

（C）instance_name

（D）db_name

（A）SQL> conn c##usr/pwd@pdb2
You are unable to create a connection. You first need to sync PDB2 by executing:
SQL> conn / as sysdba
SQL>exec DBMS_PDB.SYNC_PDB;

（B）SQL> conn c##usr/pwd@pdb2
You are connected to PDB2 successfully.

（C）SQL> conn c##usr/pwd@pdb1
You are connected to PDB1 successfully.

（D）SQL> conn c##usr/pwd@pdb2
You are unable to create a connection. You need to create the common user c# #usr explicitly in
PDB2 by executing:
SQL>conn system/pwd@pdb2
SQL> CREATE USER c##usrIDENTIFIED BYpwd CONTAINER=CURRENT;
Now you are able to connect as common user c##usr to PDB2.

（A）Oracle Data Guard monitor

（B）Oracle Data Guard Broker Manager

（C）Oracle Enterprise Manager Cloud Control

（D）Oracle Data Guard command-line interface (DGMGRL)

（A）Mike and Tim need to individually take backups of their respective PDBs, because CDB-level backup does not include PDB data dictionary objects.

（B）Mike and Tim do not need to worry, because recovery of individual PDBs is possible.

（C）Recovery of individual PDBs is not possible, because John did not back up by using RMAN>Backup Pluggable database pdb1 pdb2. However, complete CDB recovery is still possible.

（D）Recovery of individual PDBs is not possible at all.

（A）a solution that provides zero-data-loss protection at any distance without impacting database performance

（B）a solution for disaster protection and database rolling upgrades for a mission-critical OLTP database, where you also want to extract data from a data guard primary database for ETL update o' an enterprise data warehouse

（C）a solution that helps with integrated automatic database and client failover between source and target, where you also need to establish advanced replication (such as multi master and bidirectional replication and data transformations)

（D）a solution requiring minimal planned downtime and risk, using standby first patching, database rolling upgrades, and select platform migrations

（A）Undo reverses a change, whereas redo re-creates a change.

（B）Redo protects against inconsistent reads, whereas undo protects against data loss.

（C）Redo reverses a change, whereas undo re-creates a change.

（D）Undo protects against inconsistent reads, whereas redo protects against data loss.

（B）It configures Oracle Messaging Gateway.

（C）It enables the Oracle Data Mining option in your Oracle binary files.

（D）It generates Client Static Library.

（E）It configures one of the Oracle user accounts.

（A）Peer-to-peer for 1 Broadcast for 2 Bi-directional for 3 Consolidation for 4

（B）Uni-directional for 1 Peer-to-peer for 2 Bi-directional for 3 Consolidation for 4

（C）Peer-to-peer for 1 Consolidation for 2 Broadcast for 3 Cascading for 4

（D）Uni-directional for 1 Broadcast for 2 Bi-directional for 3 Consolidation for 4

（A）Security Patch Update (SPU) is the primary means of releasing security fixes for Oracle products. SPUs are cumulative with respect to prior SPUs and generally contain only security fixes.

（B）Patch Set is the main way in which Oracle provides bug fixes in between releases. Oracle bundles a number of fixes, tests them thoroughly together, and packages, then together for easy download and installation.

（C）Patch Set Update (PSU) is a collection of proactive, stabilizing, cumulative patches for a particular product version (base release or patch set). PSUs are cumulative and include all the security fixes from CPU patches, plus additional fixes.

（D）Terminal Patch Set is an unsupported patch set by Oracle Lifetime Support policies.

（E）Interim patches, also known as "one-off" patches, are created to provide a specific fix between the releases of patch sets.
