Correct Answer: ACETo properly set up and configure Field Service for automatic scheduling of work orders to the most appropriate resource, there are three essential settings: Firstly, the Field Service-Administrator security role must be assigned to the Resource Scheduling Optimization (RSO) user. This ensures the user has the necessary permissions to manage and optimize the schedule. Secondly, Resource Scheduling Optimization must be enabled to allow the system to perform the optimizations. Lastly, adding Resource Scheduling Optimization to the Field Service-Administrator profile is crucial to grant the necessary field security permissions, ensuring any restrictions or additional settings are correctly applied. Setting 'Connect to Maps' is beneficial for map-related functionalities but is not fundamental to the core requirement of automatic resource scheduling.
