Online Access Free HP0-Y50 Exam Questions

A network architect is planning an update of the server access layer in a data center. Currently, the access layer switches have 10G links to distribution layer switches. In the new solution, HP 5930 Switches act as top of rack (ToR) switches with 40G links to core switches.
Which factor must the network architect consider when designing solution?

• A.Whether the new switches 40G transceivers are on the chassis front or back, the transceivers must be on the same side as servers air outtakes
• B.Whether the data center cabling provides enough fiber strands to the racks to support the 40G links
• C.Whether the servers connecting to the new switches have NICs that support Converged Enhanced Ethernet (CEE)
• D.Whether the servers connecting to the new switches use Ethernet Virtual Bridging (EVB)/Virtual Ethernet Port Aggregate (VEPA), which is not compatible with 40G

Refer to the exhibit.

The company wants to use MSTP to handle loop suppression and Layer 2 resiliency. Which design should the network architect recommend to meet this requirement?

• A.Extend the MSTP region across the topology. Use the core switches as redundant root bridges for the IST. Use each pair of distribution switches as redundant root bridges for a different instance.
• B.Extend the MSTP region across the topology. Use the core switches as redundant root bridges for all instances in the region,
• C.Establish a different MSTP region in each distribution segment. Use the Common and Internal Spanning Tree (CIST) across the core and between distribution segments.
• D.Route traffic at the distribution layer. Establish different MSTP regions, each of which uses a different pair of distribution switches as the redundant root bridges.

The customer plans to connect 40 Voice over IP (VoIP) phones and 8 security cameras to a switch:
The architect proposes the usage form of power allocation. What are the advantages and disadvantages of this proposal?

• A.It allows the switch to connect to the PoE and PoE + devices at the same time, but the customer must purchase a redundant power supply.
• B.It allows the switch to support the PoE requirements without a redundant power supply, but power might be oversubscribed if conditions change.
• C.It allows the switch to run at a lower temperature, saving power and cooling costs, but it decreases the performance for the phones.
• D.It allows the switch to connect to the PoE and PoE+ devices on cheaper copper cable, but it limits the distance between the devices.

The exhibit shows the topology for an enterprise customer LAN with an on-site data center. The Intelligent Resilient Framework (IRF) group switches supports a group of computers that very high availability to the data center. Therefore the customer has requested a backup that extends directly between the IRF group and the data center core. All of the VLAN interfaces and routed link aggregations that are shown implement Open Shortest Path First (OSPF) in a single area.
Which tasks should the network architect complete to ensure that the HP 5500 IRF group selects the correct path to the data center during (Select two).

• A.Change the reference bandwidth on the VLAN 100 interfaces to 20000.
• B.Configure the VLAN 101 interfaces as silent interfaces.
• C.Change the reference bandwidth on the VLAN 101 interfaces to 1000.
• D.Change the reference bandwidth to 80000 on all routing devices.
• E.Set the cost on the VLAN 100 interfaces to 2Set the cost for the VLAN 101 interfaces to 80.

A customer has Voice IP (VoIP) phones that support Link Layer Discovery Protocol Media Endpoint Discovery (LLDP-MED). The phase need to receive their VLAN ID using this protocol. The network architect is proposing HP 5500-48G-PoE+EI switches. Each user computer connects to the phone, which then connects to the Ethernet jack. LLDP is enabled on the switch. Each Edge port is trunk port that permits VLAN 10 (the user VLAN) and VLAN 20 (the voice VLAN).
Which other setting recommended on the edge port?

• A.LLDP Cisco Discovery Protocol (CDP) compliance enabled
• B.The voice VLAN is enabled
• C.The PVID is set to VLAN 20
• D.The LLDP voice VLAN ID is set to 20
