• Question 291:

  HOTSPOT

  You are developing an Azure Function app.

  The Azure Function app must enable a WebHook to read an image from Azure Blob Storage and create a new Azure Cosmos DB document.

  You need to implement the Azure Function app.

  Which configuration should you use? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  Box 1: HTTP

  Trigger

  The HTTP trigger lets you invoke a function with an HTTP request. You can use an HTTP trigger to build serverless APIs and respond to webhooks.

  Box 2: Azure Blob Storage

  Input binding

  Read image from Azure Blob Storage.

  Note: Azure Functions integrates with Azure Storage via triggers and bindings. Integrating with Blob storage allows you to build functions that react to changes in blob data as well as read and write values.

  Box 3: Azure Cosmos DB

  Output binding

  Writing to an Azure Cosmos DB document.

  Box 1: Helm

  To create the ingress controller, use Helm to install nginx-ingress.

  Box 2: kubectl

  To find the cluster IP address of a Kubernetes pod, use the kubectl get pod command on your local machine, with the option -o wide .

  Box 3: Ingress Controller

  An ingress controller is a piece of software that provides reverse proxy, configurable traffic routing, and TLS termination for Kubernetes services. Kubernetes ingress resources are used to configure the ingress rules and routes for individual Kubernetes services.

  Incorrect Answers:

  Virtual Kubelet: Virtual Kubelet is an open-source Kubernetes kubelet implementation that masquerades as a kubelet. This allows Kubernetes nodes to be backed by Virtual Kubelet providers such as serverless cloud container platforms.

  CoreDNS: CoreDNS is a flexible, extensible DNS server that can serve as the Kubernetes cluster DNS. Like Kubernetes, the CoreDNS project is hosted by the CNCF.

• Question 294:

  You must implement Application Insights instrumentation capabilities utilizing the Azure Mobile Apps SDK to provide meaningful analysis of user interactions with a molbile app.

  You need to capture the data required to implement the Usage Analytics feature of Application Insights.

  Which three data values should you capture? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. Trace
  B. Session Id
  C. Exception
  D. User Id
  E. Events
  A. Trace
  D. User Id
  E. Events

  ---

  Explanation

  Application Insights is a service for monitoring the performance and usage of your apps. This module allows you to send telemetry of various kinds (events, traces, etc.) to the Application Insights service where your data can be visualized in the Azure Portal.

  Application Insights manages the ID of a session for you.

• Question 295:

  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.

  Telemetry data must synchronize the client and server information to allow HTTP request and response correlation.

  You need to reduce telemetry traffic, data costs, and storage costs while preserving a statistically correct analysis of application telemetry data.

  What should you do?

  A. Set a daily cap on the Log Analytics workspace. Create an Activity log alert rule
  B. Verify adaptive sampling is enabled Set the maxTelemetrylterns Per Second value.
  C. Set retention and archive policies by table in the Log Analytics workspace. Purge retained data beyond 30 days.
  D. Modify the pricing tier for the Log Analytics workspace.
  B. Verify adaptive sampling is enabled Set the maxTelemetrylterns Per Second value.

• Question 296:

• Question 298:

  HOTSPOT

  You are developing an Azure App Service hosted ASP.NET Core API app by using C#. The API app will allow users to authenticate by using Twitter and Azure Active Directory (Azure AD).

  Box 1: Authorize

  Box 2: X-MS-CLIENT-PRINCIPAL-NAME

  App Service passes user claims to your application by using special headers. External requests aren't allowed to set these headers, so they are present only if set by App Service. Some example headers include:

  X-MS-CLIENT-PRINCIPAL-NAME

  X-MS-CLIENT-PRINCIPAL-ID

  Here's the set of headers you get from Easy Auth for a Twitter authenticated user:

  {

  "cookie": "AppServiceAuthSession=Lx43...xHDTA==",

  ...

  "x-ms-client-principal-name": "evilSnobu", "x-ms-client-principal-id": "35....",

  "x-ms-client-principal-idp": "twitter", "x-ms-token-twitter-access-token": "35...Dj",

  "x-ms-token-twitter-access-token-secret": "OK3...Jx",
