When does an architect need to plan fast roaming for the wireless solution?

The customer has a virtualized data center. The virtual hosts use virtual distributed switches with
multiple redundant uplinks and these update control Protocol (LACP).
Which technology available in HP switches enhances high availability in this environment?

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).

After analyzing a hospital’s applications, the network architect identifies two life-critical
applications. What is the availability requirement for a life-critical application?

A customer has an existing solution, which is shown in Exhibit 1. (The solution actually includes
more access layer switches than shown.) In the existing solution, each access layer switch routes
traffic.
A network architect is proposing the HP Flex Campus solution shown in Exhibit 2. In this proposed
solution, the core Intelligent Resilient Framework (IRF) virtual switch routes traffic but the access
layer switches do not. The customer links that in the existing solution if an access layer uplink fails,
failover occurs in less than a second.
The customer also likes that the existing solution does not require Virtual Router Redundancy
Protocol (VRRP).
What should the architect tell the customer about the benefits of the proposed solution?

An architect is planning an HP Wired-WLAN solution for an office with approximately 4000 users
who will use the wireless network rather heavily and who need to roam seamlessly. The solution
will have 256 MSM 460 APs. What is one reason for using two HP Wired-WLAN controllers for this
solution?

Refer to the exhibit.

A network architect is designing the logical topology for a campus LAN networking solution. The
solution includes:
80 HP 5500-48G EI switches at the access layer
20 access layer Intelligent Resilient Framework (IRF) virtual devices (four members in each IRF)
3840 edge ports total
The solution must support VoIP phones as well as desktop computers.

Which VLAN design shown in the exhibit meets the customer needs and also follows best
practices?

Refer to the exhibit.

The core routing switches will run OSPF. Which design provides the best failover and resiliency?

A network architect has scheduled an outage to install a new networking solution. What should
ideally be the device state before the outage?

What is a benefit of the HP Dynamic Virtual Private Network (DVPN) technology?
