   Answer: See figure below

   Explanation

   Correct The src attribute should point to the Application Insights JavaScript SDK, which is hosted on a CDN. This allows the browser to load the necessary script to send telemetry data. The cfg attribute is used to configure Application Insights, and it requires the connection string to send telemetry data to the correct Application Insights resource.

2. Question 392 · 462 in bank

   You develop an ASP. Net Core application by integrating the Application Insights SDK into your solution. The application sends a very high rate of telemetry in a short time interval. You observe a reduced number of events, traces, and metrics being recorded and increased error rates for telemetry ingestion. You need to reduce telemetry traffic, data costs, and storage costs while preserving a statistically correct analysis of application telemetry data. Your solution must ensure that you will be able to correlate HTTP request and response data. What should you do?

   • AConfigure a Log Analytics workspace data collection rule (DCR). Use a Kusto Query Language (KQL) statement to filter incoming data.
   • BDisable adaptive sampling. Enable and configure the fixed-rate sampling module.
   • CSet a daily cap on the Log Analytics workspace. Create an Activity log alert rule.
   • DConfigure the TelemetryConfiguration object in the instrumented code. Increase the metric aggregation interval to 15 minutes.

   Show answer

   Answer: B

   Explanation

   The issue in the scenario describes high telemetry ingestion leading to data loss and increased error rates. To reduce telemetry traffic, data costs, and storage costs while maintaining statistical accuracy and correlation of HTTP requests and responses, the best approach is to use fixed-rate sampling. Unlike adaptive sampling, which dynamically adjusts based on load, fixed-rate sampling provides predictable control over telemetry volume.

   Answer: See figure below

   Explanation

   Answer is correct: "If adaptive or fixed rate sampling methods are enabled for a telemetry type, ingestion sampling is disabled for that telemetry." and "Ingestion sampling happens at the Application Insights service endpoint. (...) It doesn't reduce telemetry traffic sent from your app, but helps you keep within your monthly quota." https://learn.microsoft.com/en-us/azure/azure-monitor/app/sampling-classic-api

   You are creating a hazard notification system that has a single signaling server which triggers audio and visual alarms to start and stop. You implement Azure Service Bus to publish alarms. Each alarm controller uses Azure Service Bus to receive alarm signals as part of a transaction. Alarm events must be recorded for audit purposes. Each transaction record must include information about the alarm type that was activated. You need to implement a reply trail auditing solution. Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

   • AAssign the value of the hazard message SessionID property to the ReplyToSessionId property.
   • BAssign the value of the hazard message MessageId property to the DevileryCount property.
   • CAssign the value of the hazard message SessionID property to the SequenceNumber property.
   • DAssign the value of the hazard message MessageId property to the CorrelationId property.
   • EAssign the value of the hazard message SequenceNumber property to the DeliveryCount property.
   • FAssign the value of the hazard message MessageId property to the SequenceNumber property.

   Show answer

   Answer: AD

   Explanation

   Answer is correct. ReplyToSessionId (reply-to-group-id) This value augments the ReplyTo information and specifies which SessionId should be set for the reply when sent to the reply entity. CorrelationId (correlation-id) Enables an application to specify a context for the message for the purposes of correlation; for example, reflecting the MessageId of a message that is being replied to.

8. Question 398 · 462 in bank

   Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You are developing an Azure solution to collect point-of-sale (POS) device data from 2,000 stores located throughout the world. A single device can produce 2 megabytes (MB) of data every 24 hours. Each store location has one to five devices that send data. You must store the device data in Azure Blob storage. Device data must be correlated based on a device identifier. Additional stores are expected to open in the future. You need to implement a solution to receive the device data. Solution: Provision an Azure Service Bus. Configure a topic to receive the device data by using a correlation filter. Does the solution meet the goal?

   • AYes
   • BNo

   Show answer

   Answer: B

   Explanation

   First of all - that question is not about THE BEST solution but about THE VALID solution. So responses like "Event Hub is the best choice" doesn't bring anything to the table. That being said - is the provided solution valid? I would say NO, because: - topics allows multiple subscribers, and here we need to process each event once - correlation filter is for subscriptions, not topics - even when assuming there is typo in the question and correlation filter is defined on the subscription level - it still is not a valid solution, because new stores can be opened in the future with many new device identifiers which you can't know in advance. Besides that filter make no sense in this scenario whatsoever, you just need to save data in storage account and basically partition it by device identifier.

    Answer: See figure below

    Explanation

    While importing the API into APIM, if we select Azure App Service, then backend is preselected to Azure Resource and Gateway Credentials option was disabled. Now I changed it to http(s) endpoint from Azure Resource, Gateway Credentials option is enabled with 3 options none, Basic and Client Certificate. for 1st box both Azure Resource Http(s) endpoint are valid. for 2nd box, based on the first option multiple answers possible. So its not clear. I believe this question should have more than one answer.
