A. Option A
B. Option B
C. Option C
D. Option D
Answer: B
Explanation: * XmlWriterTraceListener
Directs tracing or debugging output as XML-encoded data to a TextWriter or to a Stream,
such as a FileStream.
* TraceListener.TraceEvent Method (TraceEventCache, String, TraceEventType, Int32) Writes trace and event information to the listener specific output.
Syntax:
[ComVisibleAttribute(false)]
public virtual void TraceEvent(
TraceEventCache eventCache,
string source,
TraceEventType eventType,
int id
)
Q87. DRAG DROP - (Topic 1)
An application serializes and deserializes XML from streams. The XML streams are in the following format:
The application reads the XML streams by using a DataContractSerializer object that is declared by the following code segment:
var ser = new DataContractSerializer(typeof(Name));
You need to ensure that the application preserves the element ordering as provided in the XML stream.
How should you complete the relevant code? (To answer, drag the appropriate attributes to the correct locations in the answer area-Each attribute 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.)

Q89. - (Topic 1)
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 Counter1 is available for use in Windows Performance Monitor (PerfMon).
Which code segment should you insert at line 16?
A. CounterType = PerformanccCounterType.RawBase
B. CounterType = PerformanceCounterType.AverageBase
C. CounterType = PerformanceCounterType.SampleBase
D. CounterType = PerformanceCounterType.CounterMultiBase
Answer: C
Explanation:
PerformanceCounterType.SampleBase - A base counter that stores the number of sampling interrupts taken and is used as a denominator in the sampling fraction. The sampling fraction is the number of samples that were 1 (or true) for a sample interrupt. Check that this value is greater than zero before using it as the denominator in a calculation of SampleFraction.
PerformanceCounterType.SampleFraction - A percentage counter that shows the average ratio of hits to all operations during the last two sample intervals. Formula: ((N 1 - N 0) / (D 1 - D 0)) x 100, where the numerator represents the number of successful operations during the last sample interval, and the denominator represents the change in the number of all operations (of the type measured) completed during the sample interval, using counters of type SampleBase. Counters of this type include Cache\Pin Read Hits %. http://msdn.microsoft.com/en-us/library/system.diagnostics.performancecountertype.aspx
