B. 1, 5, 7, 2, 3, 6; step 4 is not required

Which statement is true in this scenario?
A. The minimum memory size for the database buffer cache is set to 100 MB.

set to 100 MB.
C. The minimum memory size allocated for a server process in the database buffer cache in dedicated
mode is set to 100 MB.
D. The maximum memory size from the database buffer cache that can be released for dynamic
distribution during ASMM is set to 100 MB.
Examine the values for the following initialization parameters:
Which two will be the implications of these values in your database? (Choose two.)

What affect would this command have on the database?
A. The extents in the undo tablespace retain data until the next full database backup
B. The extents containing committed undo in the undo tablespace are not overwritten for at least 15 minutes
C. The extents containing committed data in the undo tablespace are not overwritten until the instance
is shut down
D. The extents containing committed undo in the undo tablepace are transferred to Flash Recovery Area
before being overwritten

B. The database instance will shut down and the error details will be logged in the alert log file

Recovery Area implicitly

Which is the correct description of a pinned buffer in the database buffer cache?
A. The buffer is currently being accessed
B. The buffer is empty and has not been used
C. The contents of the buffer have changed and must be flushed to the disk by the DBWn process

B. When DBAs need to connect remotely to start up the database instance
C. When users need to connect the database instance using the host naming method
D. When the database instance that is to be registered with the listener is configured in shared server mode
While observing the index statistics, you find that an index is highly fragmented, thereby resulting
in poor database performance. Which option would you use to reduce fragmentation without affecting the users who are currently using the index?
A. Validate the index structure using the ANALYZE …. INDEX command
B. Rebuild the index using the ALTER INDEX ….. REBUILD ONLINE command
