第5题：

While setting up the thresholds 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.

第7题：

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.

第8题：

Which two of these are differences between traffic policing and traffic shaping？（）
