HP0-Y51 Online Practice Questions and Answers

An administrator plans to deploy a wireless network, which might need to support a mix of 802.11g and 802.11n clients in the 2.4 GHz frequency. The administrator wants to prioritize transmissions for 802.11 n clients. Which 2.4 GHz radio setting helps to prevent slow clients from taking more than their share of transmission time?

A. Set up the channel reuse option.

B. Set up the fair scheduling option.

C. Set the mandatory data rate for 802.11g as low as possible.

D. Set the multicast data rate for 802.11n as low as possible.

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

B. Enable spanning tree on the OpenFlow-enabled switches but set the application as the spanning tree flood parameter controller.

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

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

A. 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.

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 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.

D. HP APs can transmit multicasts as broadcasts or unicasts, helping to ensure higher transmission rates and more reliable delivery for multicast.

The HP Comware switch places VLAN 2, which is associated with 10 1.2.0/24, in OpenFlow instance 1. The switch supports IP routing and is configure with the default gateway IP address in VLAN 2. An SDN application has created the flow entry shown in the exhibit to route traffic from 10.1.2.0/24 to 10.1.3.0/24. The exhibit does not show the output interface for the flow. Which output interface supports the needs of this scenario?

A. Any port that is a member of VLAN 2

B. Any port in the controller VLAN

C. Normal

D. Controller

An administrator is configuring an MPLS and VPLS Martini to connect customer Sites 1, 2, and

3. The administrator has created Virtual Switch Instance (VSI) "CustomerA" for this purpose. How should the administrator connect customer Site 1 to the VPLS solution?

A. Create a service instance on the VLAN assigned to g1/0/1. Also create a global cross-connect group, and bind the CustomerA VSI and the service instance in that group.

B. Create a service instance on g1/0/1. Also create a global cross-connect group, and bind the CustomerA VSI and the service instance in that group.

C. Create a service instance on the VLAN assigned to g1/0/1. Bind (cross-connect) that instance to the CustomerA VSI.

D. Create a service instance on g1/0/1. Bind (cross-connect) that instance to the CustomerA VSI.

An administrator wants to establish a remote LDP session between PE-1 (loopback IP address 10.0 0.1) and PE-2 (loopback IP address; 10.0.0.2). What is required to do this?

A. Both PE-1 and PE-2 have a VPN instance that is defined with the same route distinguisher (RD)

B. Both PE-1 and PE-2 advertise the same label for their loopback IP address

C. Both PE-1 and PE-2 use ordered mode for LDP.

D. Both PE-1 and PE-2 advertise their loopback IP address with OSPF and with LDP.

An administrator is setting up an EVI solution on four HP Comware switches. The switches reach each other on these IP address:

Switch1 = 10.1.1.1

Switch2 = 10 2.2 2

Switch3 = 10.3.3.3

Switch4 = 10.4.4.4

The administrator wants to make Switch1 and Switch2 potential EVI Network Discovery Protocol (ENDP) servers. What is the proper configuration on the Switch1 EVI tunnel interface?

A. evi neighbor-discovery server enable evi neighbor-discovery client enable 10.1.1.1

B. evi neighbor-discovery server enable evi neighbor-discovery client enable 10.2.2.2

C. evi neighbor-discovery client enable 10.3.3.3 evi neighbor-discovery client enable 10.4.4.4

D. evi neighbor-discovery client enable 10.3.3.3 evi neighbor-discovery client enable 10.4.4.4

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 team leader role, increasing the total number of RESTful API and Java API calls 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 load balance the Master OpenFlow controller role, increasing the total number of packetin messages per second that the solution can handle.

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

A. VSAN 1 and VSAN 2 to VLAN 10

B. VSAN 1 and VSAN 2 to VLAN 1; VSAN 1 to VLAN 10; VSAN 2 to VLAN 20

C. VSAN 1 and VSAN 2 to VLAN 10; VSAN 1 and VSAN 2 to VLAN 20

D. VSAN 1 to VLAN 10; VSAN 2 to VLAN 20
