2. Install the SALES_APP application in the application root and the common tables in both the CDB root and the application root.
3. Create an application seed.
4. Install the SALES_APP application in the application seed.
5. Create the SALES_APP1 and SALES_APP2 application PDBs.
6. Sync the SALES_APP1 and SALES_APP2 application PDBs with the application root.
7. Sync the SALES_APP1 and SALES_APP2 application PDBs with the application seed.
8. Sync the application seed with the application root.
Which are the minimum required steps in the correct sequence?

A. 1,3,5,6,7
B. 1,5,6
C. 2,5,6
D. 1,3,5,7

A. Itsucceeds only if the target database is greater than 400M.
B. It fails because connection to the AUXILIARY instance must be as SYSDBA.
C. It fails because no parallel channels are allocated for the auxiliary database.
D. No catalogued backup of the TARGET is used to duplicate the database.
E. It succeeds.

問題 #5

Which two are true about poorly performing SQL statements and their tuning in Oracle database instances? (Choose two.)

A. SQL statements performing many physical I/Os can always have their performance improved by creating indexes.
B. SQL statements doing only logical reads never require tuning because they do no physical I/O.
C. The solution that best optimizes one SQL statement can degrade the performance of others.
D. SQL statements doing joins always do more physical I/O than single table queries.
E. Poorly performing SQL statements can be tuned automatically by the Oracle server.
