  You are developing a web app named mywebapp1. Mywebapp1 uses the address myapp1.azurewebsites.net. You protect mywebapp1 by implementing an Azure Web Application Firewall (WAF). The traffic to mywebapp1 is routed through

  an Azure Application Gateway instance that is also used by other web apps.

  You want to secure all traffic to mywebapp1 by using SSL. Solution: You open the Azure Application Gateway's HTTP setting and set the Override backend path option to mywebapp1.azurewebsites.net. You then enable the Use for App

  service option.

  Does this meet the goal?

  A. Yes

  B. No

  Correct Answer: A

  The ability to specify a host override is defined in the HTTP settings and can be applied to any back-end pool during rule creation.

  The ability to derive the host name from the IP or FQDN of the back-end pool members. HTTP settings also provide an option to dynamically pick the host name from a back-end pool member's FQDN if configured with the option to derive

  host name from an individual back-end pool member.

  SSL termination and end to end SSL with multi-tenant services. In case of end to end SSL, trusted Azure services such as Azure App service web apps do not require whitelisting the backends in the application gateway. Therefore, there is no

  need to add any authentication certificates.

• Question 364:

  You have two Hyper-V hosts named Host1 and Host2. Host1 has an Azure virtual machine named VM1 that was deployed by using a custom Azure Resource Manager template.

  You need to move VM1 to Host2.

  What should you do?

  A. From the Update management blade, click Enable.

  B. From the Overview blade, move VM1 to a different subscription.

  C. From the Redeploy blade, click Redeploy.

  D. From the Profile blade, modify the usage location.

  Correct Answer: C

  When you redeploy a VM, it moves the VM to a new node within the Azure infrastructure and then powers it back on, retaining all your configuration options and associated resources.

  Solution: You access the Virtual Machine blade.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  View template from deployment history

  Go to the resource group for your new resource group. Notice that the portal shows the result of the last deployment. Select this link.

  

  You see a history of deployments for the group. In your case, the portal probably lists only one deployment. Select this deployment.

  

  The portal displays a summary of the deployment. The summary includes the status of the deployment and its operations and the values that you provided for parameters. To see the template that you used for the deployment, select View template.

  You are developing an Azure solution to collect point-of-sale fPOS) 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 Event Hub. Configure the machine identifier as the partition key and enable capture.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: A

• Question 369:

  You develop and add several functions to an Azure Function app that uses the latest runtime host. The functions contain several REST API endpoints secured by using SSL. The Azure Function app runs in a Consumption plan.

  You must send an alert when any of the function endpoints are unavailable or responding too slowly.

  You need to monitor the availability and responsiveness of the functions.

  What should you do?

  A. Create a URL ping test.

  B. Create a timer triggered function that calls TrackAvailability() and send the results to Application Insights.

  C. Create a timer triggered function that calls GetMetric("Request Size") and send the results to Application Insights.

  D. Add a new diagnostic setting to the Azure Function app. Enable the FunctionAppLogs and Send to Log Analytics options.

  Correct Answer: B

  You can create an Azure Function with TrackAvailability() that will run periodically according to the configuration given in TimerTrigger function with your own business logic. The results of this test will be sent to your Application Insights resource, where you will be able to query for and alert on the availability results data. This allows you to create customized tests similar to what you can do via Availability Monitoring in the portal. Customized tests will allow you to write more complex availability tests than is possible using the portal UI, monitor an app inside of your Azure VNET, change the endpoint address, or create an availability test even if this feature is not available in your region.

• Question 370:

  You are developing applications for a company. You plan to host the applications on Azure App Services. The company has the following requirements:

  1.

  Every five minutes verify that the websites are responsive.

  2.

  Verify that the websites respond within a specified time threshold. Dependent requests such as images and JavaScript files must load properly.

  3.

  Generate alerts if a website is experiencing issues.

  4.

  If a website fails to load, the system must attempt to reload the site three more times.

  You need to implement this process with the least amount of effort.

  What should you do?

  A. Create a Selenium web test and configure it to run from your workstation as a scheduled task.

  B. Set up a URL ping test to query the home page.

  C. Create an Azure function to query the home page.

  D. Create a multi-step web test to query the home page.

  E. Create a Custom Track Availability Test to query the home page.

  Correct Answer: D

  You can monitor a recorded sequence of URLs and interactions with a website via multi-step web tests. Incorrect Answers:

  A: Selenium is an umbrella project for a range of tools and libraries that enable and support the automation of web browsers.

  It provides extensions to emulate user interaction with browsers, a distribution server for scaling browser allocation, and the infrastructure for implementations of the W3C WebDriver specification that lets you write interchangeable code for all major web browsers.
