HP Master ASE HP0-Y51 Questions & Answers

  • Question 21:

    Table of Acronyms

    Refer to the exhibit.

    The switches shown in the exhibit form a TRILL region. What helps to load balance traffic across the .inks between these switches?

    A. The TRILL cost for each link is the same, and TRILL Equal Cost Multi-Path (ECMP) is enabled.

    B. VLANs 10, 20, and 30 are mapped to different spanning tree instances.

    C. The switch-to-switch links are configured to permit at least two VLANs.

    D. Switch 4 and Switch 5 are assigned the same Designated RBridge (DRB) priority.

  • Question 22:

    How does the HP Optimizer SDN Application -Microsoft Lync enhance QoS for Microsoft Lync?

    A. The application registers as a packet listener for all IP packets in the HP VAN SDN Controller. It creates reactive flows for all user traffic, including prioritized ones for UCandC traffic.

    B. The application pre-provisions several flows on all HP switches, which redirect all IP traffic to the HP VAN SDN Controller. Each TCP session is then assigned the correct priority before it can be established.

    C. The application receives RESTful API calls from a plug-in to Lync. It uses information obtained to create proactive prioritized flows for UC and traffic.

    D. The application registers as a packet listener for TCP 5060 in the HP VAN SDN Controller. It uses packets received to create reactive prioritized flows for UC and C traffic.

  • Question 23:

    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.

  • Question 24:

    Refer to the exhibit.

    The exhibit shows the Fibre Channel (FQ zones that are members of zonesets on an HP Comware switch. How does this zoning affect the FC fabric operation?

    A. Host bus adapter (HBA) pWWNs in zoneset 1 belong to VSAN 1, which is currently active. HBA pWWNs in zoneset 2 belong to VSAN 2, which is inactive

    B. Server pWvVNs in zone 1 can discover targets pWWNs in zone 2. Server pWWNs in zone 3 can discover target pWWNs in zone 4.

    C. A sender pWWN in zone 1 can discover target pWWNs in zone 1. A server pWWN in zone 2 can discover target pWWNs in zone 2.

    D. The switch matches a host bus adapter (HBA) pWWN to entries in zone 1 to determine whether an HBA can connect to a port. If it does not find a match, it checks zone 2.

  • Question 25:

    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 northbound Java APIs to integrate with and configure Ethernet Virtual Bridging (EVB) applications

    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 southbound RADIUS APIs to provision dynamic VLANs on data center switches, basing those VLANs on the customer identity

  • Question 26:

    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.

  • Question 27:

    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.

  • Question 28:

    When should an administrator enable hybrid mode on an HP VAN SDN Controller?

    A. When the controller must manage HP Provision switches that use virtualization mode to enable OpenFlow on some VLANs but not on others

    B. When the controller must manage HP Provision switches that operate in passive mode

    C. When the controller must manage Mininet switches in a developer environment and HP switches in a production environment

    D. When the controller must manage OpenFlow-enabled switches that support both OpenFlow 1.0 and 1.3

  • Question 29:

    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.

  • Question 30:

    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.
