Question 6 of 90
A customer wants to deploy an HP ProVision-based network with laptops daisy chained to physical IP phones. The customer also wants the laptop traffic to be managed by OpenFlow, while the phones use traditional QoS. Which OpenFlow switch instance configuration option should the customer use?
Correct Answer: C
Question 7 of 90
What is an advantage of using the HP Network Optimizer SDN application with UC&C applications rather than just the SDN applications?
Correct Answer: D
The first capability that's implemented is the ability of the Lync server (or any communications server, potentially) to dynamically provide to the network controller the IP addresses/ports of the paired endpoints of a real time flow. This enables the network to mark, without deep packet inspection, those flows with a CoS/QoS tag that will give them the proper treatment in the network. This becomes a positive identification of "authorized" real-time flows; any device/flow trying to use that tagging that is not "authorized" through the API can automatically be re-tagged to a best effort service class.
This technique has a number of critical advantages over current techniques. When compared to the typical VLAN, it enables positive tagging of a variety of devices, including BYOD and potentially other systems that might have multiple traffic types (e.g., a PC running a soft client or a tablet).
In addition, when compared to deep packet inspection at each access element, it reduces cost as well as eliminating the errors and complexity that encryption of the packet stream can introduce.
