11. View the Exhibit to examine the metrics(標準) with a threshold(閾值). Which statement is true regarding the Number of Transactions (per second) metric?

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.

知識點：

Adaptive thresholds can automatically set warning and critical alert thresholds for some system metrics using statistics derived(推導) from metric values captured in the moving window baseline.
