Wait, are you sure about Ethereum? I thought it was still PoW.

Hyperledger and Corda don’t use PoW, just Bitcoin.

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.

Okay, I've got this. The key is that the destination is locator-controlled, so option D is the correct answer.
