A. The index is not used by the optimizer but is maintained during DML operations.
B. The index is not used by the optimizer and is not maintained during DML operations.
C. The index is used by the optimizer only if a hint is specified in the query statement and is maintained during DML operations.

Q17. While performing the backup of the flash recovery area, you notice that one of the archived redo log files is missing. You have multiple destinations for archived redo log files. What implications does it have on the backup of the flash recovery area?
A. The backup succeeds but it would be without the missing archived log.
B. The backup fails because one of the archived redo log files is missing.
C. The backup succeeds because it fails over to one of the alternative archived redo log destinations.
D. During backup, you are prompted for the alternative destination for the missing archived redo log file.
Q18. Identify three key features of ASM. (Choose three.)
A. file striping
B. allocation unit mirroring
C. automatic disk rebalancing

E. automatic undo management
Q19. View the Exhibit to examine the metrics with a threshold.
Which statement is true regarding the Number of Transactions (per second)metric?
A. Oracle uses statistical relevance to determine when an adaptive threshold has been breached for the metric.
B. The statistics for the metric values observed over the baseline time period are not examined to determine threshold values.
C. Oracle determines when an adaptive threshold has been breached based on the maximum value captured by the baseline.
D. The total concurrent number of threshold violations, which must occur before an alert is raised for the metric, has been set to zero.
Q20. You are in the process of creating a virtual private catalog in your Oracle Database 11g database. The PROD1, PROD2, and PROD3 Oracle Database 10g databases are registered in the base recovery catalog. The database user who owns the base recovery catalog is CATOWNER. CATOWNER executes the following command to grant privileges to a new user VPC1 using Oracle Database 11g RMAN executables:
RMAN> GRANT CATALOG FOR DATABASE prod1, prod2 TO vpc1;
Then you issue the following commands:
RMAN> CONNECT CATALOG vpc1/oracle@catdb;
RMAN> SQL "EXEC catowner.dbms_rcvcat.create_virtual_catalog;"
What is the outcome of the above commands?
A. They execute and create a virtual catalog for pre-Oracle 11g clients.
B. They produce an error because PROD1 and PROD2 databases belong to the older version.
C. They produce an error because you need to connect as CATOWNER to execute this packaged procedure.
D. They produce an error because you need to connect to the target database to execute this packaged procedure.
