質問 3

Refer to the exhibit.

Mininet is being used by a developer to test an OpenFlow RESTful API application developed in Python. The developer is able to view the switches in the OpenFlow topology diagram shown in the exhibit, but no hosts are displayed in the topology diagram. The same behavior is seen when making a RESTful API call for nodes via the RESTful API. Switch information is provided via API calls from the HP VAN SDN Controller, but no nodes are shown.
What is a possible issue?

（A）Traffic needs to be sent by the Mininet nodes before they will be discovered by the HP VAN SDN Controller.

（B）The developer is using the incorrect API calls and needs to ensure that tokens are sent when requesting information from the HP VAN SDN Controller

（C）OpenFlow communication between Mininet and the HP VAN SDN Controller is not functioning correctly. Wireshark can be used to aid with troubleshooting the OpenFlow communication.

（D）The Topology Service has been stopped on the HP VAN SDN Controller and needs to be started.
