Q96. View the Exhibit to examine the output of the DBA_OUTSTANDING_ALERTS view.
After 30 minutes, you executed the following command:

A. An Automatic Workload Repository snapshot has been taken recently.
B. The non-threshold-based alerts are transferred to DBA_ALERT_HISTORY.
C. The threshold alerts conditions are cleared and the alerts are transferred to BA_ALERT_HISTORY.
D. The threshold alerts related to database metrics are permanently stored in DBA_ALERT_HISTORY but not the threshold alerts related to instance metrics.
Q97. User A executes the following command to drop a large table in your database:
SQL> DROP TABLE trans;
While the drop table operation is in progress; user B executes the following command on the same table;
SQL> DELETE FROM trans WHERE tr_type='SL'
Which statement is true regarding the DELETE command?

B. It deletes the rows successfully because the table is locked in the SHARE mod
C. It fails to delete the records because the table is locked in EXCLUSIVE mode

Q98. A constraint in a table is defined with the INITIALLY IMMEDIATE clause. You executed the ALTER TABLE command with the ENABLE VALIDATE option to enable the constraint that was disabled.
What are the two effects of this command? (Choose two.)
A. It fails if any existing row violates the constraint.
B. It does not validate the existing data in the table.
C. It enables the constraint to be enforced at the end of each transaction.
D. It prevents insert, update, and delete operations on the table while the constraint is in the process of being enabled.
Q99. You are in the middle of a transaction updating a very important table. The machine on which a database was running reboots because of power outage. This caused a database instance failure.
Which statement is true in this situation?

D. The lower bounds of PGA_AGGREGATE_TARGET and SGA_TARGET parameters are set to 90 MB and 270 MB, respectively.
