Free HP HP0-Y51 Exam Dumps Questions & Answers

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

Refer to the exhibit.

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

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 northbound RESTful APIs to receive information from servers and switches acting as Network Functions Virtualization (NFV)-complaint routers
• C.  By using southbound RADIUS APIs to provision dynamic VLANs on data center switches, basing those VLANs on the customer identity
• D.  By using northbound Java APIs to integrate with and configure Ethernet Virtual Bridging (EVB) applications

Refer to the exhibit.

A company has HP APs that are managed by the two Unified Wired-Wireless controllers. Wireless
users use Wi-Fi Protected access (WPA2) and authenticate with 802.1X to HP Access Manager (UAM). The SSID uses centralized forwarding. Users need to be able to roam seamlessly from area 1 to area 2.
Which step helps to meet these needs?

• A.  Change the security mode to preshared key (PSK) and enable opportunistic key change (also called "fast roaming").
• B.  Set up enable a roam that includes both controllers.
• C.  Configure controller 1 as a backup controller for APs in area; configure controller 2 as a backup controller for APs in area1.
• D.  Configure local forwarding for the SSID on both controllers.

The switch shown in the exhibit should from a TRILL region. For Switch 1 interface ten1/0/22, what is a valid port link-type and TRILL port type?

• A.  port link type = trunk port that permits VLMs 10 and 20 TRILL- port type = TRILL access port
• B.  port link type = access port in any VLAN TRILL port type = TRILL access port
• C.  port link type = hybrid port with untagged VLANs 10 and 20 TRILL port type = TRILL hybrid port
• D.  port link type = access port in any VLAN TRILL port type = TRILL trunk port
