A network architect is planning a solution for a customer’s campus LAN. The customer has a
existing network that consists of three tiers. The new HP switches are being deployed at the
access layer, and the existing network infrastructure is using Cisco Per-VLAN Spanning Tree
(PVST+) between the access layer and the distribution layer.

The customer has listed support for PVST+ as a top requirement for the solution, and the
customer network managers are somewhat hostile to the idea of adding HP switches.
What should the network architect do?

A.
The network architect should convince the network managers to migrate the entire network to
Multiple Spanning Tree Protocol (MSTP) based on the flexibility of the protocol.

B.
The network architect should check whether the existing switches support smart link and then
work with the customer to implement that protocol across the network instead of link aggregation
or spanning tree.

C.
The network architect should select HP switches that support PVST+ and use intelligent
Resilient Framework (IRF) for other benefits

D.
The network architect explain that, although HP switches do not support PVST+, they do
support Intelligent Resilient Framework (IRF), which eliminates the need for any loop protection.
