An HP VAN SDN Controller runs the HP Network Protector SDN Application. The application has programmed an HP Switch with flows that output to the service insertion tunnel. How does the switch forward packets matching these flows to the controller?

• A.Encapsulated in OpenFlow packets and transmitted in the controller VLAN
• B.Encapsulated in OpenFlow packets and transmitted over the auxiliary connection
• C.Encapsulated in an IPSec tunnel
• D.Encapsulated in a GRE tunnel

What is one benefit of the HP patent for Adaptive Multicast channel width and Guard Interval 802.11n?

• A.HP APs can adapt the precise frequency on which they transmit to each client, enabling them to transmit multicasts to more than one clients at the same time.
• B.HP APs can adjust whether they send multicasts over a bonded channel based on the 802.11 standards supported on device in the current environment.
• C.HP APs can transmit multicasts as broadcasts or unicasts, helping to ensure higher transmission rates and more reliable delivery for multicast.
• D.HP APs can bind up to three channels together for any multicast transmissions in the 5 GHz frequency range, including 802.11a and 802.11n.

An administrator is setting up an MPLS and L2VPN virtual circuit (VC) between customer Site 1 and Site 2. The administrator is creating a global cross-connect group, which uses LDP signaling, on PE-1. Which two elements are required to do this?

• A.An AC connection (specifies a service instance on g1/0/1) and a peer (PE-2)
• B.A peer (PE-2) and a VPN instance (associated with g1/0/1)
• C.An AC connection (specifies a service instance on g1/0/1) and a VPN instance (associated with g1/0/1)
• D.A peer (PE-2) and a VLAN ID (access VLAN or. g1/0/1)

A company is deploying an HP Unified Wired-Wireless controller solution with an HP BYOD solution. Guests will connect to an open Guest SSID and be redirected by their default gateway to a portal hosted by User Access Manager (UAM). The default gateway is a Comware routing device.
The administrator has set up portal authentication on the Comware device to implement the redirect. The administrator asks the BYOD solution designer about the correct RADIUS and domain settings for portal authentication on the switch. What should the BYOD solution designer explain to the administrator?

• A.The administrator does not need to make any changes as long as the switch is managed by IMC. UAM will automatically access the managed switch and configure the correct settings.
• B.The RADIUS scheme and domain must be configured with the same settings that would be used for traditional portal authentication to UAM. In addition, the RADIUS scheme must enable transparent MAC authentication.
• C.These settings are not necessary because the UAM BYOD portal automatically handles the authentication and then forces the guest to reconnect the SSID and authenticate with MAC-Auth.
• D.The RADIUS scheme and domain must be configured with the same settings that would be used for traditional portal authentication to UAM. In addition, the RADIUS scheme must use the standard server type.

The switches shown in the exhibit use the HP VAN SDN Controller as the OpenFlow controller. They connect to the controller on their out-of-band management (OOBM) ports, but these connections are not shown in the exhibit. The switches also run spanning tree protocol. An SDN application installed on the HP VAN SDN Controller is programmed to discover live ports, find redundant paths, and create loopfree paths for traffic infrastructure shown in the exhibit. However the application is not able to complete these functions because the switches are reporting some ports as blocked.
What should the administrator do to let the application create the loopfree paths?

• A.Enable spanning tree on the OpenFlow-enabled switches and configure all of the redundant links as egress-only-ports
• B.Disable spanning tree on the OpenFlow-enabled switches and configure the redundant links as static link aggregations
• C.Enable spanning tree on the OpenFlow-enabled switches but set the application as the spanning tree flood parameter controller.
• D.Disable spanning tree on the OpenFlow-enabled switches and do not configure link aggregation.
