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.
What should you do?

You are developing an ASP.NET MVC application. The application has a page that searches for and displays
an image stored in a database. Members of the EntityClient namespace are used to access an ADO.NET Entity
Framework data model. Images and associated metadata are stored in a database table.
You need to run a query that returns only the image while minimizing the amount of data that is transmitted.
Which method of the EntityCommand type should you use?

You are supporting a WCF data contract that returns a price calculation that can be expanded to add new data
members.
Clients using the old version of the data contract must be supported.
You need to define the data contract so that the data serializer can put unknown data members into a property
bag.
You have the following code:
Which code segments should you include in Target 1 and Target 2 to complete the data contract? (To answer,
drag the appropriate code elements to the correct targets in the answer area. Each code element 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
