Explanation
Box 1: address
Box 2: "http://Service1/EmployeeService.svc"
In WCF, an EndpointAddress models an endpoint reference (EPR) as defined in the WS-Addressing standard.
The address URI for most transports has four parts. For example, this URI, "
http://www.fabrikam.com:322/mathservice.svc/secureEndpoint" has the following four parts:
Scheme: http:
Machine: www.fabrikam.com
(Optional) Port: 322
Path: /mathservice.svc/secureEndpoint
Box 3:
The names and namespaces of the .NET types in the definition of contracts and operations are significant
when contracts are converted into WSDL and when contract messages are created and sent. Therefore, it is
strongly recommended that service contract names and namespaces are explicitly set using the Name and
Namespace properties of all supporting contract attributes such as the ServiceContractAttribute,
OperationContractAttribute, DataContractAttribute, DataMemberAttribute, and other contract attributes.

You deploy a RESTful ASP.NET Web API to manage order processing.
You are developing an Azure App Services Web App to consume the API and allow customers to order
products. You use the HttpClient object to process order entries. The API throws SocketException errors when
the Web App experiences a high volume of concurrent users.
You need to resolve the errors.

You are developing a Web API by using ASP.NET Core. You plan to deploy the Web API to a 5-node Service
Fabric cluster that is hosted in Azure.
You identify the following requirements:
* You must be able to debug the Web API on a local Service Fabric instance before deploying to Azure.
* The Web API must run on every node in the Service Fabric cluster when deployed to Azure.
* The Service Fabric configuration must support scaling of additional nodes.
You need to configure the Web API for local and Azure deployment.
How should you configure the environments? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

InstanceCount Default value is -1 which means that DnsService is running on every node. OneBox needs this
to be set to 1 since DnsService uses well known port 53, so it cannot have multiple instances on the same
machine.

Errors occasionally occur when saving data using the FlightInfoContext ADO.NET Entity Framework context.
Updates to the data are being lost when an error occurs.
You need to ensure that data is still saved when an error occurs by retrying the operation. No more than five
retries should be performed.
Which code segment should you use as the body of the SaveChanges() method in the FlightInfoContext.es
file?

You manage an ASP.NET Core E-Commerce application that is deployed to Azure App Service. You plan to
use Application Insights for collecting telemetry data.
You must prepare a report that describes utilization patterns of uses. The report must include the following
information:
* the Country or Region from which users access the application
* how often and for how long users browse the catalog
* how many Canadian customers visited the offers page
* how much time Premium customers spend on the support page
* the percentage of users that added items to a shopping cart and completed purchases
You need to collect the required data.
Which tool should you use? To answer, drag the appropriate tools to the correct requirements. Each tool may
be used once, more than once, or mot at all. You may need to drag the split bar between panes or scroll to view

Explanation
Box 1 Geography: Users
"the Country or Region from which users access the application"
The Users panel allows you to understand important details about your users in a variety of ways. You can use
this panel to understand such information as where your users are connecting from, details of their client, and
what areas of your application they're accessing.
Box 2: Feature usage: Session
" how often and for how long users browse the catalog"
The Sessions panel is similar to the Users panel. Where Users helps you understand details about the users
accessing your application, Sessions helps you understand how those users used your application.
Box 3 Canada Offers: Cohorts
" how many Canadian customers visited the offers page"
A Cohort is a set of users grouped on similar characteristics. You can use cohorts to filter data in other panels
allowing you to analyze particular groups of users. For example, you might want to analyze only users who
completed a purchase, or users from Canada.
Box 4 Premium support: Cohorts
"how much time Premium customers spend on the support page"
A Cohort is a set of users grouped on similar characteristics. You can use cohorts to filter data in other panels
allowing you to analyze particular groups of users. For example, you might want to analyze only users who
completed a purchase, or users from Canada.
Box 5: Buyer behavior: Funnels
"the percentage of users that added items to a shopping cart and completed purchases"
Funnels focus on what you want users to do. A funnel represents a set of steps in your application and the
percentage of users who move between steps. For example, you could create a funnel that measures the
percentage of users who connect to your application who search product. You can then see the percentage of
users who add that product to a shopping cart, and then the percentage of those who complete a purchase.
