What configuration change can you make to cause IS-IS to select the optimal path based on the interface bandwidth?

You have just enabled IS-IS on the lab testing network. You notice that IS-IS is not using the optimal path selection based on the interface bandwidth. Currently, the IS-IS routing process seems to be selecting the best path based on the hop count.

What configuration change can you make to cause IS-IS to select the optimal path based on the interface bandwidth?
A . Enable a wide-style IS-IS metric.
B . Enable a narrow-style IS-IS metric.
C . Change the default auto-cost reference bandwidth to a higher value.
D . Change the default IS-IS metric on each of the router interfaces to better correspond to the interface bandwidth.
E . Change the interface bandwidth by using the bandwidth interface configuration mode command.
