HOTSPOT -
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.
Each correct selection is worth one point.

Suggested Answer:
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.
