Evaluate the following command:SQLALTER SYSTEM SET db_securefile = ‘IGNORE‘;What is the impact of this setting on the usage of SecureFiles?() A. It forces BasicFiles to be created even if the SECUREFILE option is specified to create the LOBB. It forces SecureFiles to be created even if the BASICFILE option is specified to create the LOBC. It does not allow the creation of SecureFiles and generates an error if the SECUREFILE option is specified to create the LOBD.

Users are performing a large volume of inserts and deletes on the application tables in the APPS tablespace. You observe that there are several warning alerts being generated for the APPS tablespace space usage metrics. Currently, the warning threshold for the tablespace space usage metrics is set to 70%. To make the generated alerts more useful as a problem identification tool, you want to reduce the frequency of alert generation for the tablespace space usage metrics for the APPS tablespace. What should you do?()A、disable SQL tracing for theAPPS tablespaceB、disable logging attribute for the APPS tablespaceC、modify the tablespace to be a dictionarymanaged tablespaceD、increase the critical threshold value for the tablespace space usage metrics for the APPS tablespaceE、increase the warning threshold value for the tablespace space usage metrics for the APPS tablespace
The warning and critical threshold values have been set to 85% and 97%, respectively, for one of the tablespaces. The current tablespace space usage is 54%. You modify the warning threshold to be 50 % and critical threshold to be 53% in Database Control. Which statement is true?()A、 The new setting would be applied but no alerts would be raised immediately.B、 The new setting would be applied and an alert would be raised immediately.C、 The new setting would be ignored because the tablespace space usage is more than the specified threshold value.D、 The new setting would cause an error because the tablespace space usage is more than the specified threshold value.
Which statements are true regarding SecureFile LOBs?() A、 The amount of undo retained is user controlled.B、 SecureFile LOBs can be used only for nonpartitioned tables.C、 Fragmentation is minimized by using variable-sized chunks dynamically.D、 SecureFile encryption allows for random reads and writes of the encrypted data.E、 It automatically detects duplicate LOB data and conserves space by storing only one copy.
You want to be notified when the space usage of an existing critical tablespace has reached 75% of the allocated space. Which option would you use to achieve this?()A、run a procedure to check the tablespace space usageB、define the warning threshold for the tablespace at 75% in Database ControlC、create a trigger to be executed when tablespace space usage reaches 75%D、submit a job by using DBMS_JOB package to check the free space in the tablespace at regular intervalsE、define the warning threshold to be 75% for the tablespace by ALTER TABLESPACE ..
