All switches in this figure are HP Provision ASIC switches. They are enabled to establish adjacency with
neighbors on all of their VLAN interfaces. Besides these configurations, they are operating at the default OSPF
settings. How can a network administrator ensure that routing switch B uses the 10G link to reach 10.1.10.0/24
if its direct link to routing switch A fails?

A.
Set the VLAN 103 OSPF cost to 10.

B.
Set the VLAN 100 bandwidth to 10000.

C.
Set the VLAN 100 OSPF cost to 10.

D.
Set the VLAN 103 bandwidth to 1000.
E. Set its reference bandwidth to 10000.

Explanation:
(You have to modify the reference Value to change OSPF calculations, and choose the 10G link)
By default, an interfaces OSPF cost is based on the port speed of the interface. The cost is calculated by
dividing the reference bandwidth by the port speed.The default reference bandwidth is 100 Mbps, which
results in the following default costs:
10 Mbps port 10
All other port speeds 1
The software uses the following formula to calculate the cost:
Cost = reference-bandwidth/interface-speed
