An SDN application needs to create reactive flow table entries in response to specific packets. The flow_mod APIs will create the actual entries, but application must be configured with another API as part of this function.
What is that API?

• A. A sequence packet listener (SPL) API that specifies the Director role and the match criteria for the packets
• B. A sequence packet listener (SPL) API that specifies the Advisor role and the match criteria for the packets
• C. A listener API that registers the application to listen for meters
• D. A listener API that registers the application to listen for data paths

When should an administrator enable hybrid mode on an HP VAN SDN Controller?

• A. When the controller must manage OpenFlow-enabled switches that support both OpenFlow 1.0 and 1.3
• B. When the controller must manage Mininet switches in a developer environment and HP switches in a production environment
• C. When the controller must manage HP Provision switches that operate in passive mode
• D. When the controller must manage HP Provision switches that use virtualization mode to enable OpenFlow on some VLANs but not on others

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

• A. 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.
• B. 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.
• C. 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.
• D. The application receives RESTful API calls from a plug-in to Lync. It uses information obtained to create proactive prioritized flows for UC & traffic.

An HP Unified Wired-Wireless controller controls an AP. The AP implements centralized forwarding. It supports 802.11n clients that implement Wi-Fi Multimedia (WMM) or 802.11 e. Some of the clients are sending traffic in high priority WMM queues.
How does the AP help to ensure that this traffic is prioritized in the wired LAN?

• A. It maps 802.11 values from wireless traffic to DiffServ Code Points (DSCP) in packets tunneled to the controller.
• B. It implements 802.11n fair scheduling on the port that connects to the switch.
• C. It maps 802.1p values from wireless traffic to 802.11 e values in packets forwarded into the LAN.
• D. It implements Spectralink and uses Spectralink-to-WMM compliance mode.

An administrator has set up an HP BYOD solution for an HP MSM760 controller and its APs.
These are the specifications:
-Guests should only have to register and log in once After that, the guest device should be
automatically logged in. -User Access Manager (UAM) provides the portal in which guests register their own accounts. -The MSM760 is connected to a Comware switch, which redirects unregistered guests to the
UAM portal.
Currently guests can reach the portal, register for their accounts, and log in. However, guests report that they cannot reach the Internet after they log in. When the administrator asks the guests to disconnect from the wireless network and then connect again, they succeed in reaching the Internet.
What could fix this problem?

• A. In the Comware switch settings, add the guest router to the free rule list
• B. Configure SOAP settings for the MSM controller on UAM.
• C. Configure the Comware switch to accept dynamic authorization updates from UAM.
• D. In the DHCP scope for the onboarding VLAN, lower the lease time to about 10 seconds.
