Architecting HP FlexNetwork Solutions

Refer to the exhibit.

The exhibit shows a proposed design for a data center network infrastructure. The exhibit shows two racks for simplicity. The data center will actually include more racks.
The customer has these key requirements:
✑ The customer can scale any application and easily install new hardware that supports that application
✑ The network supports vMotion for live migration of virtual machine (VMs)
How should the network architect change the proposed design to meet the customer requirements?

Refer to the exhibit.

The exhibit shows the topology for an enterprise LAN with an on-site data center. The intelligent Resilient Framework (IRF) group of HP 5500 Series switches supports a group of computers that require very high availability to the data center. Therefore, the customer has requested a backup gigabit fiber link 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 normal operation?

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 customer wants a simple solution for deploying virtual services at a branch. Which devices support modules running a VMware ESXi hypervisor? (Select two)

What correctly describes one trend that is changing how network architects must design the data center network infrastructure?
