 A client can suggest a list of higher cipher suites to use during `ClientHello`. However, some of them might not be supported by IoT Hub (for example, `ECDHE-ECDSA-AES256-GCM-SHA384`). In this case, IoT Hub will try to follow the preference of the client, but eventually negotiate down the cipher suite with `ServerHello`.
