It is importan to mention that the question is not talking about in a specific device type. They could be ip phones, Telepresence devices, webex devices, desk devices, etc. so I do not think B be correct. In fact, it is necessary to allow devices to reach control hub, A must be correct, to provision and download firmware updates. However, also it is true that the devices, since they are onboarding and changing from CUCM to Control Hub, need to have a license with a Flex Plan, The caveat is that A talk about HTTP. It must be HTTPS using TLS1.2. SO I think correct answer is D. It is necessary to have licenses for each one device in general. You must verify that sufficient Webex Device licenses are available to support your devices in the cloud.
