Correct Answer:
Explanation:
Box 1: PhysicalFileProvider
Box 2: Directory
Code example.
There are three types of IFileProvider Implementations -
Physical File Provider - it is used to access the actual or physical file of the system Embedded File Provider - it is used to access files that are embedded in assemblies Composite File Provider - it is used to provide combine access to the files from one or more providers.
Box 3: Pathstring
Code example:
app.UseStaticFiles(new StaticFileOptions()
{
FileProvider = new PhysicalFileProvider(
Path.Combine(Directory.GetCurrentDirectory(), @"MyStaticFiles")),
RequestPath = new PathString("/StaticFiles")
});

Question 6
You are developing an ASP.NET Core application. You have the following code:
You create a folder named Content in your project. You add a controller action that uses authorization and returns a FileResult object.
The application must meet the following requirements:
Use Kestrel as the server.
Serve static files from the wwwroot folder and publicly cache the files for five minutes.
Serve static from the Content folder to authorized users only.

For the wwwroot folder. We serve static files from the wwwroot folder
Box 2: UseStaticFiles
Box 3: UseStaticFiles
Serve static from the Content folder to authorized users only.
Note the two app.UseStaticFiles calls. The first one is required to serve the CSS, images and JavaScript in the wwwroot folder (Box 1), and the second call (box 3) for directory browsing of the content folder Code example:
app.UseStaticFiles(new StaticFileOptions()
{
FileProvider = new PhysicalFileProvider(
Path.Combine(Directory.GetCurrentDirectory(), @"MyStaticFiles")),
RequestPath = new PathString("/StaticFiles")
});

Question 8
You manage an application that has a custom API. Your company purchases another company. Employees from the purchased company use their own Microsoft Azure Active Directory (Azure AD).
You need to reconfigure the application to ensure that all users can access the application by using the API. You have the following requirements:
Implement authentication for Azure API management.
Configure the API gateway for proper authorization.
Integrate metrics into one dashboard.
Apply additional restrictions to all roles.
What should you implement? To answer, configure the appropriate options in the dialog box in the answer area.

Correct Answer:
Explanation:
Box 1: Groups
Add an external Azure AD group
After you enable access for users in an Azure AD instance, you can add Azure AD groups in API Management. Then, you can more easily manage the association of the developers in the group with the desired products.
To configure an external Azure AD group, you must first configure the Azure AD instance on the Identities tab by following the procedure in the previous section.
You add external Azure AD groups from the Groups tab of your API Management instance.
Box 2: Policies
Policies are applied inside the gateway which sits between the API consumer and the managed API. The gateway receives all requests and usually forwards them unaltered to the underlying API. However a policy can apply changes to both the inbound request and outbound response.
Box 3: Application Insights
Application Insights is an extensible Application Performance Management (APM) service for web developers on multiple platforms. Use it to monitor your live web application.
Box 4: Role-Based Access Control (RBAC)
Apply additional restrictions to all roles.
Azure API Management relies on Azure Role-Based Access Control (RBAC) to enable fine-grained access management for API Management services and entities (for example, APIs and policies).

Question 11
You are developing an ASP.NET MVC application that processes payments for an online retailer The retailer provides a .NET assembly that contains a class named Retail EventSource That derives from the EventSource class.
The RetailEventSource class has a method named SuspiciousTransaction that returns True when the order originates from a system that differs significantly from the system that usually performs orders. The RetailEventSource class also has a field named PaymentProcessed that stores the event identifier for a payment-processed event.
Events must be written only when the event source is in a state where writing events is valid You need to create a derived type that contains the method to raise a PaymentProcessed event
