You have specified the warning and critical threshold values

第1题：

While designing your database， you have created the EMPLOYEES table as an index/x7forganized table （IOT）. You want to create a bitmap index on the JOB_ID column to make queries faster. Which task must have been completed so that you are able to create the bitmap index？（）

• A、A primary key must have been created.
• B、A mapping table must have been created.
• C、An overflow tablespace must have been specified.
• D、The PCTTHRESHOLD option must have been specified.

第2题：

You have specified the warning and critical threshold values of an application tablespace to be 60% and 70% respectively. From the tablespace space usage metrics， you find that the actual space usage has reached the specified warning threshold value， but no alerts have been generated. What could be the reason for this？（）

• A、 The EVENT parameter was not set
• B、 The SQL_TRACE parameter is set to FALSE
• C、 The Enterprise Manager Grid Control is not used
• D、 The STATISTICS_LEVEL parameter is set to BASIC
• E、 The TIMED_STATISTICS parameter is set to FALSE

第4题：

You are maintaining your OLTP database in Oracle10g. You have not set the warning level and critical level threshold values for space usage of the DATA1 tablespace. What will be the impact？（）

• A、 No warning level or critical level alert will be generated.
• B、 A warning level alert will never be generated， but a critical level alert will be generated when 97 percent space of the DATA1 tablespace is used.
• C、 A critical level alert will never be generated， but a warning level alert will be generated when 85 percent space of the DATA1 tablespace is used.
• D、 A warning level alert will be generated at 85 percent space usage of the DATA1 tablespace， and a critical level alert is generated at 97 percent space usage of the DATA1 tablespace.

第5题：

While designing your database， you have created the EMPLOYEEStable as an index-organized （IOT）. You want to create a bitmap index on the JOD_IDcolumn to make queries faster. Which task must have been completed so that you are able to create the bitmap index？（）

• A、 A primary key must have been created.
• B、 A mapping table must have been created.
• C、 An overflow tablespace must have been specified.
• D、 The PCTTHRESHOLD option must have been specified.

第6题：

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.

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10题：

An online tablespace, TEST_TBS, is full and you realize that no server-managed tablespace threshold alerts were generated for the TEST_TBS tablespace. What could be the reason, if the TEST_TBS tablespace does not include autoextensible data files?（）
