A. The collection level for the AWR should be set to BASIC
B. The moving window size must be less than Undo Retention
C. The moving window size should be greater than the Automatic Workload Repository (AWR) retention period
D. The moving window size should be equal to or less than the Automatic Workload Repository (AWR) retention period
第2题：
View the Exhibit exhibit1 to examine the series of SQL commands. View the Exhibit exhibit2 to examine the plans available in the SQL plan baseline. The baseline in the first row of the Exhibit is created when OPTIMIZER_MODE was set to FIRST_ROWS.Which statement is true if the SQL query in exhibit1 is executed again when the valueof OPTIMIZER_MODE is set to FIRST_ROWS?（）
A. The optimizer uses a new plan because none of the plans in the exhibit2 are fixed plans.
B. The optimizer uses the plan in the second row of the exhibit2 because it is an accepted plan.
C. The optimizer uses the plan in the first row of the exhibit2 because it is the latest generated plan.
D. The optimizer uses the plan in the first row of the exhibit2 because OPTIMIZER_MODE was set to FIRST_ROW during its creation.

A. Oracle uses statistical relevance to determine when an adaptive threshold has been breached for the metric.
B. The statistics for the metric values observed over the baseline time period are not examined to determine threshold values.
C. Oracle determines when an adaptive threshold has been breached based on the maximum value captured by the baseline.
D. The total concurrent number of threshold violations, which must occur before an alert is raised for the metric, has been set to zero.
