While setting up the threshold for tablespace space usage metrics for one of your tablespaces， you define the critical threshold as 60% and warning threshold as 75%. What would be the result of this setting？（）A、 It would result in an error because the warning threshold cannot be more than the critical threshold.B、 The warning threshold is ignored and alerts would be generated when space usage exceeds the critical threshold.C、 The critical threshold is ignored and alerts would be generated when space usage exceeds the warning threshold.D、 Both threshold values are used and alerts are generated when space usage exceeds the respective threshold values.

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%.

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

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.
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 .. ADD THRESHOLD command
