UseAuthentication, Use Authorization, UseAzureAppConfiguration. The last option allows dynamic configuration to be reloaded without an app restart. https://docs.microsoft.com/en-us/azure/azure-app-configuration/enable-dynamic-configuration-aspnet-core?tabs=core5x

It is irrelevant in this case, the boxes only have ONE correct option each and those are, box1: authentication, box2: authorization, box3: app config.

The UseAzureAppConfiguration is not available in the first list of options, only the last list of options. Also, for configuring the app the order only matters sometimes. It doesn't in this case.

i have doubt regarding UseAuthentication UseAuthentication - this is not in the code snippet in the above link public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { .......... app.UseAzureAppConfiguration(); app.UseHttpsRedirection(); app.UseStaticFiles(); app.UseRouting(); app.UseAuthorization(); }

Box 1: UseAuthentication Need to validate users before users are allowed access to secure resources. UseAuthentication adds the AuthenticationMiddleware to the specified IApplicationBuilder, which enables authentication capabilities. To verify users, we need to use the Authentication middleware. Box 2: UseAuthorization Need to permit users to access secure resources. UseAuthorization adds the AuthorizationMiddleware to the specified IApplicationBuilder, which enables authorization capabilities. To authorize users to access resources , we need to use the Authorization middleware. Box 3: UseAzureAppConfiguration Adding the UseAzureAppConfiguration middleware to allow the configuration settings registered for refresh to be updated while the ASP.NET Core web app continues to receive requests. For using feature flags, you need to make use of the Azure App Configuration service. To ensure the configuration settings are refreshed without the need to restart the web app, you can use the middleware of UseAzureAppConfiguration();

Answer is: UseAuthentication, UseAuthorization, UseAzureAppConfiguration. You need to use the feature flags for the requirement to enable the export feature. For that you have to call UseAzureAppConfiguration. See: https://learn.microsoft.com/en-us/azure/azure-app-configuration/use-feature-flags-dotnet-core?tabs=core6x The UseStaticFiles should normally be called first before authentication, but it does not meet any requirement to choose this as an option.
