HP0-Y51 Online Practice Questions and Answers

A company is deploying an HP Unified Wired-Wireless controller solution with an HP BYOD solution. Guests will connect to an open Guest SSID and be redirected by their default gateway to a portal hosted by User Access Manager (UAM). The default gateway is a Comware routing device.

The administrator has set up portal authentication on the Comware device to implement the redirect. The administrator asks the BYOD solution designer about the correct RADIUS and domain settings for portal authentication on the switch. What should the BYOD solution designer explain to the administrator?

A. The administrator does not need to make any changes as long as the switch is managed by IMC. UAM will automatically access the managed switch and configure the correct settings.

B. These settings are not necessary because the UAM BYOD portal automatically handles the authentication and then forces the guest to reconnect the SSID and authenticate with MAC-Auth.

C. The RADIUS scheme and domain must be configured with the same settings that would be used for traditional portal authentication to UAM. In addition, the RADIUS scheme must use the standard server type.

D. The RADIUS scheme and domain must be configured with the same settings that would be used for traditional portal authentication to UAM. In addition, the RADIUS scheme must enable transparent MAC authentication.

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.

An SDN application needs to create reactive flow table entries in response to specific packets. The flow_mod APIs will create the actual entries, but application must be configured with another API as part of this function.

What is that API?

A. A sequence packet listener (SPL) API that specifies the Director role and the match criteria for the packets

B. A listener API that registers the application to listen for data paths

C. A listener API that registers the application to listen for meters

D. A sequence packet listener (SPL) API that specifies the Advisor role and the match criteria for the packets

An administrator creates user "monitor", who should have read only access to the HP VLAN SDN Controller. The administrator needs to enter this command to

finish up the user account.

keystone user-add-role - -user-ID ID1 - - tenant-id ID2 - -role-ID ID3

What are the correct values for ID1, ID2, and ID3?

A. ID1 = 94; ID2 = a6; ID3=0c

B. ID1 = a6; ID2 = 0c; ID3=94

C. ID1 = 9b; ID2 = a6; ID3=d0

D. ID1 = a6; ID2 = 0c; ID3=d0

A company has an HP BYOD solution. The administrator is setting up synchronization of user accounts from Active Directory (AD). The administrator wants User Access Manager (UAM) to organize the user accounts in groups in the same way that AD does.

How does the administrator configure this to accomplish the goal?

A. Establish the LDAP synchronization policy, and then create a user group policy to synchronize the groups and sort the user accounts

B. In the LDAP Server policy, set the User Group setting to Synchronize by OU, which allows AD to create the groups automatically

C. Install the UAM agent on the AD server, otherwise, UAM can only synchronize the highest- level group of domain users.

D. Create every group before setting up the LDAP synchronization policy

Refer to the exhibit.

A company has many dual-radio APs that are deployed relatively closely together. They are controlled by an HP Unified Wired-Wireless controller. The administrator wants to implement load balancing among the radios on different APs.

How should the administrator implement load balancing?

A. Implement group-based load balancing by adding radios on different APs to the group.

B. Implement radio-based load balancing by adding APs to the radio templates.

C. Implement AP-based load balancing on the individual APs.

D. Implement AP-based load balancing on the radios of the individual APs.

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. Can support wireless clients and scan wireless traffic.

B. It can support wireless clients, scan wireless traffic, and implement countermeasures

C. It can implement countermeasures and scan wireless traffic.

D. It can scan wireless traffic and wired traffic.

Refer to the exhibit.

A company has two HP Unified Wired-Wireless controllers. The MSM APs in Area 1 in the exhibit are controlled by Controller1. The MSM APs in Area 2 in the exhibit are controlled by Controlled. The company purchases a Controlled to provide backup for both Controller1 and Controller2 (N+1 redundancy).

How does the administrator set up the APs in Area 1 so that they contact Controlled if Controller1 fails?

A. Create a roam group that includes Controller1, Controlled, and Controlled. Make sure that Controlled has the highest IP address

B. Create AP templates for the area 1 APs on Controlled and set its connection priority for these APs to 7.

C. Create a backup AC configuration group between Controller1 and Controlled. Enable Fast Backup on the group.

D. On Controller1, configure the new controller's IP address as the backup controller for the APs

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. 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

B. 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.

C. 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.

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

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
