Exhibit 1

Exhibit 2

A customer has a 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 FlexCampus 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 likes that in the existing solution STP does not block either access layer uplink. 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?

A.
Although the IRF core must implement VRRP, STP does not block either access layer uplink,
letting failover occur more quickly

B.
STP does not block either access layer uplink, and routing redundancy is provided without
VRRP

C.
Although the IRF core must implement VRRP, VRRP is easier to set up than a dynamic routing
protocol on all the switches

D.
STP will block one uplink on each access layer switch, but IRF enables failover to occur much
more quickly
