Table of Acronyms

Refer to the exhibit.

An administrator is planning an MPLS and VPLS Martini to connect customer sites 1, 2, and 3. How many pseudo must the administrator define?

• A.Four-two on PE-1, one on PE-2 m and one on PE-3
• B.Two-two on PE-1, with one connected to PE-2 and PE-3
• C.Three-one each on PE-1, PE-2, and PE-3
• D.Six-twoeach on PE-1, PE-2, and PE-3

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

A company has an external SDN application that works with an HP VAN SDN Controller. The application programmer has tried testing several RESTful API calls but receives authentication errors. What does the administrator need to explain to the programmer?

• A.Every RESTful API call must include an X-Auth token. The token can be obtained by sending a calf with valid credentials https.Controller_IP.8443/sdn/v2.0/auth
• B.Every RESTful API call must include an X-Auth token. The token must be created by a valid certification authority (CA) and installed on both the controller and external application in advance.
• C.The application must be installed with a certificate that is signed by the same certification authority (CA) that signed the VAN SDN Controller certificate.
• D.Every RESTful API call must include a valid username and password. The only exception is when the AuthRequired parameter is set to false in restful conf file.

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

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

• A.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.
• B.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.
• 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.
