You have a System Center Operations Manager 2007 environment. You are creating a single threshold monitor for a performance counter object. You need to create the monitor so that the state changes only if the performance counter exceeds the threshold a specific number of times in succession over a given time period. What should you do?

A.
Create an Average threshold monitor.

B.
Create a Consecutive samples over threshold monitor.

C.
Create a Delta threshold monitor.

D.
Create a Simple threshold monitor.

Explanation:
B: CORRECT

Consecutive Samples Over Threshold: This type of monitor alleviates some of the false positives that you may obtain when using a simple threshold. Simple thresholds only monitor when an object exceeds a limit, but do not take into account those objects that may spike periodically.
Processor utilization and network utilization are good examples of this. There may be short bursts of network activity, or the processor might be momentarily taxed, but they quickly return to normal activity. The consecutive samples over threshold will not change its state until several samples have been taken that indicate the object is still over the threshold value. For this type of threshold, you must specify the warning or error level that you are watching for, as well as the number of samples that must be taken that show the threshold being exceeded.
