You must transport the UNIVERSITY tablespace from one database to another. The UNIVERSITY tablespace is currently open read/write.
The source and destination platforms have different endian formats. Examine this list of actions:
Make the UNIVERSITY tablespace read-only on the source system.
Export the UNIVERSITY tablespace metadata using EXPDP.
Convert the UNIVERSITY tablespace data fies to the destination platform format using RMAN on the source system.
Copy the UNIVERSITY tablespace data files to the destination system.
Copy the Data Pump dump set to the destination system.
Convert the UNIVERSITY tablespace data files to the destination platform format using RMAN on the destination system.
Import the UNIVERSITY tablespace metadata using IMPDP.
Make the UNIVERSITY tablespace read/write on the destination system.
Which is the minimum number of actions required, in the correct order, to transport the UNIVERSITY tablespace?
A. 1, 2, 4, 5, 7, 8
B. 1, 2, 4, 6, 7, 8
C. 1, 2, 3, 4, 5, 7, 8
D. 1, 2, 3, 4, 5, 6, 7, 8
E. 2, 4, 5, 6, 7
Which three are true about opatchauto? (Choose three.)
It performs a shutdown and then a restart of all processes in both Oracle Grid Infrastructure and Oracle Database home during the patching process.
It must be invoked by a user with root user privileges.
Patches are applied via opatchauto.
Users must always input patch plans to opatchauto.
It requires the Oracle Grid Infrastructure and Oracle Database instances to be shut down before being invoked.

Which two are true about the character sets used in an Oracle database? (Choose two.)
Single-byte character sets provide better performance than multibyte character sets.
Unicode enables information from any language to be stored using a single character set.
Unicode is the only supported character set for Oracle databases created using Database Configuration Assistant (DBCA).
Single-byte character sets always use 7-bit encoding schemes.
Multibyte character sets allow more efficient space utilization than single byte character sets.
Single-byte character sets always use 8-bit encoding schemes.

default directories for temporary files used by temporary tablespaces
the temporary disk space used by Oracle Installer during installation
the maximum number of database files that can be opened by a database instance
Which two are true about common objects? (Choose two.)
They can be created only in CDB$ROOT.
They can be only metadata-linked in an application container.
They can exist in user-defined schemas only in application containers.

It analyzes a period of time corresponding to the 12 hours of activity.
It runs automatically after each AWR snapshot.
A DBA can run it manually.
Results are written to the alert log.
It analyzes a period of time corresponding to the last day of activity.
Which three are true about requirements for various FLASHBACK operations? (Choose three.)
FLASHBACK transaction query requires undo to retrieve all versions of a row that existed between two points in time.
FLASHBACK drop requires that the RECYCLEBIN parameter be set to ON.
FLASHBACK version query requires that the RECYCLEBIN parameter be set to ON.
FLASHBACK DATA ARCHIVE requires undo to store all versions of all rows of a table being tracked.
FLASHBACK drop requires undo to retrieve all versions of a row that existed between two points in time.

creating the OSDBA (dba) group
creating thte oraInventory (oinstall) group
creating the grid OS user

While backing up to an SBT channel, you determine that the read phase of your compressed Recovery Manager (RMAN) incremental level 0 backup is a bottleneck. FORCE LOGGING is enabled for the database.
Which two could improve read performance? (Choose two.)
Increase the size of tape I/O buffers.
Disable FORCE LOGGING for the database.
Increase the size of the database buffer cache.
Enable asynchronous disk I/O.
