Table of Acronyms Which common data center requirement does an HP EVI solution meet?

• A.It enhances multi-data center solutions by extending Layer 2 connectivity across data centers connected at Layer 3.
• B.It provides network administrators with more control over and visibility into communications between virtual machines (VMs).
• C.It increases resilience and high availability within a data center transforming Layer 2 connections into a single fabric.
• D.It enhances security for communications between data centers by automatically establishing encrypted tunnels between sites.

Table of Acronyms

A company is using Multi-CE (MCE) to create a multi-tenant data center solution. Administrators want to isolate all functions in a VPN instance "Management". Each switch has an IP address in 10.0.2.0/24 on its Management Ethernet port, and HP IMC manages the switch on these IP addresses. Administrators assign the Management Ethernet interfaces to the "Management" VPN instance. IMC begins losing data from the switches.
How should administrators fix the problem on each switch?

• A.Enable route leaking globally and on VPN instance "Management".
• B.Specify VPN instance "Management" for settings such as the SNMP trap destination
• C.Set VPN instance "Management" as the default VPN instance.
• D.Create a static route to 10.0.2.0/24 through next hop "vpn-instance Management".

Table of Acronyms A company is deploying an HP VAN SDN Controller solution, which is installed with the HP Network Protector application. The administrator configures the solution to control HP Provision switches and must choose the OpenFlow instance failover mode. Which customer requirement should cause the administrator to choose standalone mode?

• A.The company requires N+2 redundancy for the VAN SDN Controller functionality and the malware protection.
• B.The solution must work with a single VAN SDN Controller rather than a team of controllers.
• C.OpenFlow must be confined to the guest VLAN, which has the devices against which Network Protector guards the network
• D.It is vital to protect user connectivity if the controller fails, even if the network is temporarily less protected against malware

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 Java APIs to integrate with and configure Ethernet Virtual Bridging (EVB) applications
• 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 RESTful APIs to receive information from servers and switches acting as Network Functions Virtualization (NFV)-complaint routers

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