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).

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

B.
Configure the VLAN 101 interfaces as silent interfaces.

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

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

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