Correct Answer:
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 are developing a library to support multiple ASP.NET MVC web applications on a shared server. The
library provides implementations of security algorithms.
If a problem with any of the security algorithms is discovered, a new version of the library must be created and
deployed. Application downtime during the update must be minimized.
You need to ensure that the new version of the library will be used by all applications as soon as possible.

contains a unique solution that might meet the stated goals. Some question sets might have more than one
correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions
will not appear in the review screen.
You are developing a RESTful API that uses ASP.NET Core. You plan to host the API in Azure App
Services. You provision a development environment in the application service.
Developers must be able to deploy the API to the development environment. You must not share the Azure
account credentials with developers.
You need to ensure that developers can deploy the API to the development environment.
Solution: Add the developers to the same Azure Active Directory (Azure AD) as the Azure subscription in
which the App Service is provisioned. Use XCopy to deploy to the App Service.

Explanation: Only visible for FreeCram members. You can sign-up / login (it's free).
You are developing a web application by using Microsoft ASP.NET MVC.
The web application will show a list of cars and their associated prices. The list can be filtered by car model by
using a drop-down list. Access to the web application will be anonymous.
The car model list is stored as an .xml file on the application server. The car prices list is stored on a SQL
Server server.
You need to recommend a caching strategy for each scenario:
* If a user selects a car model from the drop-down list, and then closes the browser, the same model must
be selected automatically when the user reopens the web application from the same browser.
* If the car model list is updated, the drop-down list must be refreshed upon the next page reload.
* If the car prices list is updated, the prices list must be refreshed upon the next page reload.
What should you recommend? To answer, drag the appropriate caching strategies to the correct scenarios.
Each caching strategy 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.

Explanation
Box 1: outputCache
outputCache declaratively controls the output caching policies of an ASP.NET page or a user control
contained in a page.
Box 2: CacheDependency
CacheDependency establishes a dependency relationship between an item stored in an ASP.NET application's
Cache object and a file, cache key, an array of either, or another CacheDependency object. The
CacheDependency class monitors the dependency relationships so that when any of them changes, the cached
item will be automatically removed.
Box 3: SqlCacheDependency
SQL cache dependency enables you to cache pages that are dependent on data from SQL Server tables. You
can configure SQL Server and ASP.NET tocache page requests, reducing server workload, until the data on
which the page depends has been updated in SQL Server. SQL cache dependency is useful for data such as
product catalogs or customer registration information that remains comparatively static.
