How does the HP Optimizer SDN Application -Microsoft Lync enhance QoS for Microsoft Lync?

• A. The application registers as a packet listener for all IP packets in the HP VAN SDN Controller. It creates reactive flows for all user traffic, including prioritized ones for UC&C traffic.
• B. The application receives RESTful API calls from a plug-in to Lync. It uses information obtained to create proactive prioritized flows for UC & traffic.
• C. The application pre-provisions several flows on all HP switches, which redirect all IP traffic to the HP VAN SDN Controller. Each TCP session is then assigned the correct priority before it can be established.
• D. The application registers as a packet listener for TCP 5060 in the HP VAN SDN Controller. It uses packets received to create reactive prioritized flows for UC & C traffic.

Refer to the exhibit.

A company has an HP VAN SDN Controller that controls HP Provision switches. An SDN developer creates an application that needs to make many immediate decisions for handling traffic. The application is programmed to create rules such as those shown in the exhibit
Which change could improve performance by letting the hardware handle the flows?

• A. In the match criteria, list a specific Ethernet type such as IPv4.
• B. Change the idle timeout to 0 and specify table ID 200.
• C. Create a service insertion tunnel, and change this rule to output to this tunnel.
• D. Explicitly force this rule to use Table 0.

A company has an external SDN application that works with an HP VAN SDN Controller. The application programmer has tried testing several RESTful API calls but receives authentication errors. What does the administrator need to explain to the programmer?

• A. The application must be installed with a certificate that is signed by the same certification authority (CA) that signed the VAN SDN Controller certificate.
• B. Every RESTful API call must include a valid username and password. The only exception is when the AuthRequired parameter is set to false in restful conf file.
• C. Every RESTful API call must include an X-Auth token. The token can be obtained by sending a calf with valid credentials https.Controller_IP.8443/sdn/v2.0/auth
• D. Every RESTful API call must include an X-Auth token. The token must be created by a valid certification authority (CA) and installed on both the controller and external application in advance.

HP Unified Wired-Wireless controllers support wireless Intrusion Detection System (IDS)/intrusion prevention system (IPS) features. An HP AP radio is configured to participate in this solution in hybrid mode. Which functions can the hybrid mode radio fulfill?

• A. Can support wireless clients and scan wireless traffic.
• B. It can support wireless clients, scan wireless traffic, and implement countermeasures
• C. It can scan wireless traffic and wired traffic.
• D. It can implement countermeasures and scan wireless traffic.

An HP Virtual Cloud Networking (VCN) SDN Application runs on an HP VAN SDN Controller. How does VCN help to provision networking for virtualized services in a cloud solution?

• A. By using southbound OpenStack Layer 2 Agent APIs to set up the correct VLANs on virtual switches, as well as tunnels between virtual switches
• B. By using southbound RADIUS APIs to provision dynamic VLANs on data center switches, basing those VLANs on the customer identity
• C. By using northbound RESTful APIs to receive information from servers and switches acting as Network Functions Virtualization (NFV)-complaint routers
• D. By using northbound Java APIs to integrate with and configure Ethernet Virtual Bridging (EVB) applications
