Show Suggested Answer

Suggested Answer: D 🗳️
Azure Diagnostics 1.2 and 1.3 are Azure extensions that enable you to collect diagnostic telemetry data from a worker role, web role, or virtual machine running in
Azure.
Diagnostics 1.2 and 1.3 enable the collection of ETW and .NET EventSource events.
Example:
EtwProviders>
<EtwEventSourceProviderConfiguration provider="SampleEventSourceWriter" scheduledTransferPeriod="PT5M">
<Event id="1" eventDestination="EnumsTable"/>
<Event id="2" eventDestination="MessageTable"/>
<Event id="3" eventDestination="SetOtherTable"/>
<Event id="4" eventDestination="HighFreqTable"/>
<DefaultEvents eventDestination="DefaultTable" />
</EtwEventSourceProviderConfiguration>
</EtwProviders>
