The CLI is likely the most efficient means of updating the AKS deployment to utilize Application Insights, particularly by using the appInsightsEnabled parameter. The Azure Machine Learning SDK for Python provides ML capabilities, not deployment of models into AKS.

45. We plan to deploy a solution using Text Analytics and Computer Vision services in both the West US and East Europe Azure Regions. What is the minimum number of API keys required? A. 3 B. 2 C. 1 D. 4

Correct Answer: C Why is this correct? We can deploy one Cognitive Service in one of the regions and access it from apps in both. Access to that one endpoint can be via a single key. If multiple endpoints are used, then we need multiple keys. That is not the minimum scenario as the number of keys is equivalent to the number of endpoints, excluding secondary keys. Both Text Analytics and Computer Vision are accessed using the same endpoint, so the required functionality is handled by a single endpoint. However, this may not be the most reliable solution. If the one region loses connectivity to the other region, then this will fail. It would also introduce latency for that region. So while on is the minimum, it is technically better to deploy two endpoints, one in each region. Two service endpoints would require two keys, one for each (taking into account just primary and not secondary keys). This is above the minimum required, as we only need one endpoint to service both regions for all functionality. One endpoint exposed both Text Analytics and Computer Vision. One endpoint is not optimal as there could be cross-region connectivity issues, but it is the minimum.

46. We've provisioned an Azure Search service and need to deploy Cognitive Search. What should we do next? A. Search by using the REST API. B. Search by using the .NET SDK. C. Load data. D. Create an index.

Correct Answer: D Why is this correct? The next step, even before loading data, is to define an index that tells the search service how to parse and index the data

47. We have exposed our machine learning model as a web service. We want others to access and be authenticated to the web service. What two things should we provide when calling the web service? A. A resource group name B. Access key C. Endpoint URL D. Subscription ID

Correct Answer: B Why is this correct? An access key authorizes a caller of a machine learning web service and is required to make the call. Correct Answer: C Why is this correct? An endpoint URL for the web service would need to be obtained to to call the web service API.

48. We are querying a product catalog using Bing Search service and need to identify the locale of the query, the last 25 query strings, the number of calls to the service, and the top geographic regions. What should we implement? A. Azure API Management (APIM) B. Azure Application Insights C. Bing Statistics D. Azure Monitor

Correct Answer: C Why is this correct? Bing Statistics provides analytics for the Bing Search APIs. These analytics include call volume, top query strings, geographic distribution, and more. We can enable Bing Statistics in the Azure Portal by navigating to our Azure resource and clicking Enable Bing Statistics.

49. We are analyzing temperature data on IoT devices and want to send an alert into Azure when the average temperature over a 5 minute period exceeds a threshold. We would like to minimize the amount of code written. What should we use? A. A machine learning model deployed as a web service. B. Azure Functions as an IoT Edge module. C. An Azure Machine Learning model as an IoT Edge module. D. Azure Stream Analytics as an IoT Edge module.

Correct Answer: D Why is this correct? Using Stream Analytics on the edge can provide us with an efficient means of creating a solution to average values in a stream of data based upon time windows

50. We need to create an IoT solution that takes images every minute and sends the images to Azure for processing by Cognitive Services. How would we implement this capability? A. Send the images to an IoT Hub, trigger an Azure Function on each IoT Hub message, and use the function to send the data to Cognitive Services. B. Write the image to a blog in Azure Storage, trigger an Azure Function on each blob’s creation, and use the function to send the data to Cognitive Services. C. Send the images to an IoT Hub, configure Azure Automation to process each IoT Hub message, and send the data to Cognitive Services. D. Write the image to a blob in device storage, trigger an Azure Function in Azure on each blob’s creation, and use the function to send the data to Cognitive Services.

Correct Answer: A Why is this correct? IoT Hub would be used to send the data from an IoT device into Azure, where it can trigger an Azure Function, which then calls the Cognitive Service. ‘Write the image to a blog in Azure Storage, trigger an Azure Function on each blob’s creation, and use the function to send the data to Cognitive Services.’ will likely not work as an IoT device is typically not able to write to Blob storage in Azure. Note: Most likely a drag-and-drop in the exam!!
