質問 1

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 RADIUS APIs to provision dynamic VLANs on data center switches, basing those VLANs on the customer identity

（B）By using northbound Java APIs to integrate with and configure Ethernet Virtual Bridging (EVB) applications

（C）By using southbound OpenStack Layer 2 Agent APIs to set up the correct VLANs on virtual switches, as well as tunnels between virtual switches

（D）By using northbound RESTful APIs to receive information from servers and switches acting as Network Functions Virtualization (NFV)-complaint routers

質問 2

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）Disable spanning tree on the OpenFlow-enabled switches and do not configure link aggregation.

（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 configure the redundant links as static link aggregations

質問 3

A company has three HP VAN SDN Controllers, which will be deployed in a team. The administrator is deciding whether to create one region or three regions. What is a benefit of creating three regions rather than one region?

（A）The team can load balance the Master OpenFlow controller role, increasing the total number of packetin messages per second that the solution can handle.

（B）The team can provide high availability for SDN application functions rather than only for the OpenFlow controller functions rather than only for the OpenFlow controller functions.

（C）The team can provide high availability for all the OpenFlow controller functions rather than only for the SDN application functions.

（D）The team can load balance the team leader role, increasing the total number of RESTful API and Java API calls that the solution can handle.

質問 4

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）It can implement countermeasures and scan wireless traffic.

（B）It can scan wireless traffic and wired traffic.

（C）It can support wireless clients, scan wireless traffic, and implement countermeasures

（D）Can support wireless clients and scan wireless traffic.

質問 5

A company has a Unified Wired-Wireless controller solution, which uses its local portal to authenticate guests.
The company is adding an HP BYOD solution with these requirements:
-The User Access Manager (UAM) server with IP address 10.1 3.4 should provide the portal in which guests register own accounts -Guests should only have to register and log in once. After that,the guest device automatically logs inby MAC address
The administrator removes the local portal settings and begins to reconfigure the solution. What is one change that the administrator must take to the settings for the Guest SSID?

（A）Set up a remote portal server that specifies the UAM IP address and portal URL.

（B）Apply an ACL that redirects HTTP traffic to 10.1.3.4.

（C）Configure the associated WLAN-ESS interface as a hybrid port and enable MAC-based VLANs.

（D）Create a domain that specifies 10.1.3.4 as the RADIUS server and define that as the portal domain.

質問 6

A company is considering TRILL and SPBM as options for the data center architecture. The company is interested in how the solution handles load-balancing unicast traffic. What correctly describes the TRILL and SPBM options?

（A）Neither SPBM nor TRILL can use Equal Cost Multi-Path (ECMP). Both technologies can send traffic for different VLAN VLANs or I-SIDs on different links.

（B）Both SPBM and TRILL can use Equal Cost Multi-Path (ECMP) to load-balance unicasts.
provided that ECMP is enable at hardware level.

（C）SPBM can use Equal Cost Multi-Path (ECMP). TRILL does not support ECMP for unicasts, but can load-balance multicast, depending on the tree configuration.

（D）TRILL can use Equal Cost Multi-Path (ECMP). SPBM selects one best path to each SPBM switch in each B-VLAN, but can select different paths for different B-VLANs
