Question 2

Refer to the exhibit.

OpenFlow has been enabled on an HP switch and is communicating with an HP VAN SDN Controller The network administrator has checked the switch flow table entries via the controller graphical user interface, but is unsure of the format. The administrator has taken a screenshot and sent you a copy. Why does the flow table display n/a?

A. The switch has negotiated to use standard mode with the controller for this OpenFlow instance. B. The switch has negotiated to use OpenFlow 1.3 with the controller for this instance, C. The switch has negotiated to use OpenFlow 1.0 with the controller for this instance. D. The switch has negotiated to use ip-control-table-mode with the controller for this OpenFlow instance.

Question 3

Which statement best describes software-defined networking (SDN)?

A. SDN allows administrators to share software, policies, templates, and applications between multiple virtual machines that are running on the same network. B. SDN lets IT developers manage physical infrastructure devices directly without pre-defined templates or intermediary devices. C. SDN allows software to leverage the network infrastructure, enabling a centralized and policy-based approach to network provisioning and traffic forwarding. D. SDN is another name for OpenFlow, a protocol that lets switches handle traffic with OpenFlow tables rather than MAC forwarding tables and routing tables.
