QUESTION: 6 Exam Topic: Monitor, troubleshoot, and optimize Azure solutions Questions

DRAG DROP (Drag & Drop is not supported)
You develop an ASP.NET Core MVC application. You configure the application to track webpages and custom events.

You need to identify trends in application usage.

Which Azure Application Insights Usage Analysis features should you use? To answer, drag the appropriate features to the correct requirements. Each feature may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

NOTE: Each correct selection is worth one point.

See Explanation section for answer.

Answer(s): A

Explanation:

Box 1: Users

Box 2: Impact
One way to think of Impact is as the ultimate tool for settling arguments with someone on your team about how slowness in some aspect of your site is affecting whether users stick around. While users may tolerate a certain amount of slowness, Impact gives you insight into how best to balance optimization and performance to maximize user conversion.

Box 3: Retention
The retention feature in Azure Application Insights helps you analyze how many users return to your app, and how often they perform particular tasks or achieve goals. For example, if you run a game site, you could compare the numbers of users who return to the site after losing a game with the number who return after winning. This knowledge can help you improve both your user experience and your business strategy.

Box 4: User flows
The User Flows tool visualizes how users navigate between the pages and features of your site. It's great for answering questions like:
•How do users navigate away from a page on your site?
•What do users click on a page on your site?
•Where are the places that users churn most from your site?
•Are there places where users repeat the same action over and over?

Incorrect Answers:
Funnel: If your application involves multiple stages, you need to know if most customers are progressing through the entire process, or if they are ending the process at some point. The progression through a series of steps in a web application is known as a funnel. You can use Azure Application Insights Funnels to gain insights into your users, and monitor step-by-step conversion rates.

QUESTION: 7 Exam Topic: Monitor, troubleshoot, and optimize Azure solutions Questions

You develop a gateway solution for a public facing news API. The news API back end is implemented as a RESTful service and uses an OpenAPI specification.

You need to ensure that you can access the news API by using an Azure API Management service instance.

Which Azure PowerShell command should you run?

Import-AzureRmApiManagementApi -Context $ApiMgmtContext
-SpecificationFormat "Swagger" -SpecificationPath $SwaggerPath
-Path $Path
New-AzureRmApiManagementBackend -Context $ApiMgmtContext -Url
$Url -Protocol http
New-AzureRmApiManagement -ResourceGroupName $ResourceGroup
-Name $Name –Location $Location -Organization $Org
-AdminEmail $AdminEmail
New-AzureRmApiManagementBackendProxy -Url $ApiUrl

Answer(s): D

Explanation:

New-AzureRmApiManagementBackendProxy creates a new Backend Proxy Object which can be piped when creating a new Backend entity.

Example: Create a Backend Proxy In-Memory Object
PS C:\>$secpassword = ConvertTo-SecureString "PlainTextPassword" -AsPlainText -Force
PS C:\>$proxyCreds = New-Object System.Management.Automation.PSCredential ("foo", $secpassword)
PS C:\>$credential = New-AzureRmApiManagementBackendProxy -Url "http://12.168.1.1:8080" -ProxyCredential $proxyCreds

PS C:\>$apimContext = New-AzureRmApiManagementContext -ResourceGroupName "Api-Default-WestUS" -ServiceName "contoso"

PS C:\>$backend = New-AzureRmApiManagementBackend -Context $apimContext -BackendId 123 -Url 'https://contoso.com/awesomeapi' -Protocol http -Title "first backend" -SkipCertificateChainValidation $true -Proxy $credential -Description "backend with proxy server"
Creates a Backend Proxy Object and sets up Backend

Incorrect Answers:
A: The Import-AzureRmApiManagementApi cmdlet imports an Azure API Management API from a file or a URL in Web Application Description Language (WADL), Web Services Description Language (WSDL), or Swagger format.

B: New-AzureRmApiManagementBackend creates a new backend entity in Api Management.

C: The New-AzureRmApiManagement cmdlet creates an API Management deployment in Azure API Management.
