HP0-Y51 Online Practice Questions and Answers
What correctly describes the role of OpenFlow in an SDN solution?
A. OpenFlow regulates the communications among teamed SDN controllers, as well as between an SDN controller and a network infrastructure device
B. OpenFlow integrates the SDN controller into a larger management suite such as that provided in an HP CloudSystern solution.
C. OpenFlow is a communication protocol that an SDN controller can use to control devices at the network infrastructure layer.
D. OpenFlow is the open standard technology that regulates SDN control plane and application plane communications.
An HP Unified Wired-Wireless controller is configured to enforce portal authentication on a Guest SSID. The company plans to use the local portal server on the controller but needs customized portal pages that show information about the company. What is one of the rules for customizing the pages?
A. Additional pages beyond the six main pages can be loaded, but every page must include the logon.cgi action.
B. Any number of pages can be loaded, but the six main pages must use the default filenames and include script for certain actions.
C. The customized local pages must call up pages that are hosted on an external Web server such as User Access Manager (UAM).
D. The portal can only use up to six pages, but the text and logo files on these pages can be customized as desired.

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.
A company has an HP BYOD solution to let guests connect to a Guest SSID and log in through a registration page. The company needs an Employee SSID which enforces Wi-Fi Protected Access 2 (WPA2) with 802.1X. Employees must authenticate with certificates. Before authenticating with a device for the first time, the employees should be able to connect to the Guest SSID, access the guest registration page, and download valid certificates.
How does the administrator configure User Access Manager (UAM) to allow employees to download certificates from the registration page?
A. The User Endpoint Settings, create an Endpoint Configuration Distribution Policy that permits the employee groups.
B. In the Guest Manager settings for the employee manager, enable auto-registration in certificate mode.
C. In the Guest access policy, make sure that a policy binds the Employee SSID to an access rule with the onboarding VLAN ID.
D. In the Employee access service, make sure that a policy binds the Employee SSID to an access rule with the onboarding VLAN ID.
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 company is adding an HP BYOD solution. User Access Manager (UAM) should provide the portal in which guests register their own accounts. Guests should only have to register and log in once. After that, the guest device automatically logs in by MAC address.
UAM has these settings:
User account BYOD Anonymous = Assigned to Access service 1
Guest access service = Access service 2
Access service 1: Default access policy = Access policy 1
Access policy 1: No certificate authentication and User VLAN 8
Access service 2. Default access policy = Access policy 2
Access policy 2: No certificate authentication and User VLAN 88
How should the administrator configure portal authentication (HTTP redirection)?
A. Set up portal authentication to UAM in the Unified Wired-Wireless controller VLAN 88 settings
B. Set up portal authentication to UAM in the Unified Wired-Wireless controller Guest SSID settings.
C. Set up portal authentication on the default gateway for VLAN 88.
D. Set up portal authentication to UAM on the default gateway for VLAN 8.
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 in by 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. Apply an ACL that redirects HTTP traffic to 10.1.3.4.
B. Configure the associated WLAN-ESS interface as a hybrid port and enable MAC-based VLANs.
C. Create a domain that specifies 10.1.3.4 as the RADIUS server and define that as the portal domain.
D. Set up a remote portal server that specifies the UAM IP address and portal URL.
A company has an HP Unified Wired-Wireless controller that controls HP MultiService Mobility (MSM) APs. The network administrator wants to implement protection against rogue APs in the company's campus environment. Only APs that have approved MAC addresses should be allowed to operate and support clients. Controlled APs should send disassociation frames to prevent clients from connecting to rogue APs.
The administrator sets up APs to monitor the area and creates a permitted MAC address list with the approved AP MAC addresses. The administrator has not configured any other Intrusion Detection System (IDS) settings. Which additional step must the administrator complete?
A. Enable a dynamic blacklist.
B. Configure the permitted vendor and permitted SSID lists.
C. Enable countermeasures.
D. Deploy the permitted MAC address list as a static attack list to each controlled AP
An administrator is customizing an HP BYOD self-registration page. The administrator does not want guests to see the identity number field. Instead the User Access Manager (UAM) server should automatically choose a valid identity number for a guest account when the guest registers.
What are the correct settings for the identity number field in the customized page? (Select three)
A. Required
B. Fixed
C. Not required
D. Invisible
E. Random
F. Visible

An administrator has configured an HP Comware IRF virtual device to support FCoE in Fibre Channel Forwarder (FCF) mode. The IRF device supports VLAN 1, 10, 20, and 30.
The device requires two virtual SANs (VSANs), VSAN 1 and VSAN 2. An individual server might connect to for binding the VSANs. What is valid configuration to VLANs?
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
