• Question 242:

  DRAG DROP

  Your company has several websites that use a company logo image. You use Azure Content Delivery Network (CDN) to store the static image.

  You need to determine the correct process of how the CDN and the Point of Presence (POP) server will distribute the image and list the items in the correct order.

  In which order do the actions occur? To answer, move all actions from the list of actions to the answer area and arrange them in the correct order.

  Correct Answer:

  

  Step 1: A user requests the image..

  A user requests a file (also called an asset) by using a URL with a special domain name, such as .azureedge.net. This name can be an endpoint hostname or a custom domain. The DNS routes the request to the best

  performing POP location, which is usually the POP that is geographically closest to the user.

  Step 2: If no edge servers in the POP have the..

  If no edge servers in the POP have the file in their cache, the POP requests the file from the origin server. The origin server can be an Azure Web App, Azure Cloud Service, Azure Storage account, or any publicly accessible web server.

  Step 3: The origin server returns the..

  The origin server returns the file to an edge server in the POP.

  An edge server in the POP caches the file and returns the file to the original requestor (Alice). The file remains cached on the edge server in the POP until the time-to-live (TTL) specified by its HTTP headers expires. If the origin server didn't

  specify a TTL, the default TTL is seven days.

  Step 4: Subsequent requests for..

  Additional users can then request the same file by using the same URL that the original user used, and can also be directed to the same POP.

  If the TTL for the file hasn't expired, the POP edge server returns the file directly from the cache. This process results in a faster, more responsive user experience.

  The application must meet the following requirements:

  1.

  Reference the Azure Key Vault without requiring any changes to the Java code.

  2.

  Dynamically add and remove instances of the Azure Functions host based on the number of incoming application events.

  3.

  Ensure that instances are perpetually warm to avoid any cold starts.

  4.

  Connect to a VNet.

  5.

  Authentication to the Azure Key Vault instance must be removed if the Azure Function application is deleted.

  You need to grant the Azure Functions application access to the Azure Key Vault.

  Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

  Select and Place:

  

  Correct Answer:

  

  Step 1: Create the Azure Functions app with a Consumption plan type.

  Use the Consumption plan for serverless.

  Step 2: Create a system-assigned managed identity for the application.

  Create a system-assigned managed identity for your application.

  Key Vault references currently only support system-assigned managed identities. User-assigned identities cannot be used.

  Step 3: Create an access policy in Key Vault for the application identity.

  Create an access policy in Key Vault for the application identity you created earlier. Enable the "Get" secret permission on this policy. Do not configure the "authorized application" or applicationId settings, as this is not compatible with a

  managed identity.

• Question 249:

  You develop and deploy a web app to Azure App Service. The Azure App Service uses a Basic plan in a single region.

  Users report that the web app is responding slow. You must capture the complete call stack to help identify performance issues in the code. Call stack data must be correlated across app instances. You must minimize cost and impact to

  users on the web app.

  You need to capture the telemetry.

  Which three actions should you perform? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. Restart all apps in the App Service plan.

  B. Enable Application Insights site extensions.

  C. Upgrade the Azure App Service plan to Premium.

  D. Enable Profiler.

  E. Enable the Always On setting for the app service.

  F. Enable Snapshot debugger.

  G. Enable remote debugging.

  Correct Answer: DEF

  Azure Web Apps as well as API Apps and WebJobs can now be remotely profiled. If your process is running slower than expected, or the latency of HTTP requests are higher than normal and the CPU usage of the process is also pretty high,

  you can remotely profile your process and get the CPU sampling call stacks to analyze the process activity and code hot paths.

  DE: Let's say you're running a web performance test. You'll need traces to understand how your web app is running under load.

  Generate traffic to your web app by starting a web performance test or starting a Profiler on-demand session.

  View the Profiler traces after your load test or Profiler session.

  Read the Profiler performance data and call stack.

  Enable Profiler for Azure App Service apps

  First Verify "Always On" setting is enabled, and then Enable Application Insights and Profiler.

  F (not G): Enhancements in Application Insights Profiler and Snapshot Debugger (2018)

  We are pleased to announce a series of improvements on Application Insights Profiler and Snapshot Debugger. Profiler identifies the line of code that slowed down the web app performance under load. Snapshot Debugger captures runtime

  exception call stack and local variables to identify the issue in code. To ensure users can easily and conveniently use the tools, we delivered the following new features for Profiler and Snapshot Debugger.

  Incorrect:

  Not B: Application monitoring for Azure App Service and ASP.NET

  Enabling monitoring on your ASP.NET-based web applications running on Azure App Service is now easier than ever. Previously, you needed to manually instrument your app. Now the latest extension/agent is built into the App Service

  image by default.

  Manually adding an Application Insights site extension via Development Tools > Extensions is deprecated. This method of extension installation was dependent on manual updates for each new version. The latest stable release of the

  extension is now preinstalled as part of the App Service image.

  Not C: While you can use the Profiler at no extra cost, your web app must be hosted in the basic tier of the Web Apps feature of Azure App Service, at minimum.
