NEW QUESTION 235
You are developing a method named CreateCounters that will create performance counters for an application. The method includes the following code. (Line numbers are included for reference only.)
You need to ensure that Counter2 is available for use in Windows Performance Monitor (PerfMon). Which code segment should you insert at line 16?
A. CounterType = PerformanceCounterType.RawBase
B. CounterType = PerformanceCounterType.AverageBase
C. CounterType = PerformanceCounterType.SampleBase
D. CounterType = PerformanceCounterType.CounterMultiBase
PerformanceCounterType.AverageTimer32 – An average counter that measures the time it takes, on average, to complete a process or operation. Counters of this type display a ratio of the total elapsed time of the sample interval to the number of processes or operations completed during that time. This counter type measures time in ticks of the system clock.
Formula: ((N 1 -N 0)/F)/(B 1 -B 0), where N 1 and N 0 are performance counter readings, B 1 and B 0 are their corresponding AverageBase values, and F is the number of ticks per second.
The value of F is factored into the equation so that the result can be displayed in seconds. Thus, the numerator represents the numbers of ticks counted during the last sample interval, F represents the frequency of the ticks, and the denominator represents the number of operations completed during the last sample interval. Counters of this type include PhysicalDisk\ Avg.
PerformanceCounterType.AverageBase – A base counter that is used in the calculation of time or count averages, such as AverageTimer32 and AverageCount64. Stores the denominator for calculating a counter to present “time per operation” or “count per operation”..
NEW QUESTION 236
Drag and Drop Question
You are developing an application that implements a set of custom exception types. You declare the custom exception types by using the following code segments:
The application includes a function named DoWork that throws .NET Framework exceptions and custom exceptions. The application contains only the following logging methods:
The application must meet the following requirements:
– When ContosoValidationException exceptions are caught, log the information by using the static void Log (ContosoValidationException ex) method.
– When ContosoDbException or other ContosoException exceptions are caught, log the information by using the static void Log(ContosoException ex) method.
You need to meet the requirements. You have the following code:
Which code segments should you include in Target 1, Target 2 and Target 3 to complete the code? (To answer, drag the appropriate code segments to the correct targets in the answer area. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)
