I've got this! The question is asking for two Connected Field Service options, so I'm going to select the ones that seem most relevant - Azure IoT Central and Azure IoT Hub. Those should provide the proactive monitoring capabilities the company needs.

Ah, I see what they're getting at. The requirements need to be well-defined and easy to work with in an agile process. I think "unambiguous" is the way to go - that will make it easier for the dev team to implement them in iterations.
