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.
Change the reference bandwidth on the VLAN 100 interfaces to 20000

B.
Set the cost on the VLAN 100 interfaces to 2 Set the cost for the VLAN 101 interfaces to 80

C.
Change the reference bandwidth on the VLAN 101 interfaces to 1000

D.
Change the VLAN 101 interfaces as silent interfaces

E.
Change the reference bandwidth to 80000 on all routing devices
