You develop an entertainment application where users can buy and trade virtual real estate. The application must scale to support thousands of users.
The current architecture includes five Azure virtual machines (VM) that connect to an Azure SQL Database for account information and Azure Table Storage for backend services. A user interacts with these components in the cloud at any given time.
✑ Routing Service `" Routes a request to the appropriate service and must not persist data across sessions.
✑ Account Service `" Stores and manages all account information and authentication and requires data to persist across sessions
✑ User Service `" Stores and manages all user information and requires data to persist across sessions.
✑ Housing Network Service `" Stores and manages the current real-estate economy and requires data to persist across sessions.

Solution: Create a Service Fabric Cluster with a stateless Reliable Service for Routing Service. Create stateful Reliable Services for all other components.

Correct Answer: A. Yes - Create a Service Fabric Cluster with a stateless Reliable Service for Routing Service. Create stateful Reliable Services for all other components. The question is testing whether a candidate can distinguish between stateful and stateless. In this question, the routing service requirements are stateless. https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-reliable-services-introduction

You probably commented to wrong question. This one does not mention 'Guest executables' at all. The next one does.
