Interior Gateway Protocols (IGPs)

Your OSPF network includes a combination of 1GbE and 10GbE interfaces. By default, every interface in the OSPF network has the same cost. You must ensure that 10GbE interfaces are preferred when they are available.

In this scenario, which two statements would achieve this behavior?

Choose two
Explanation

OSPF calculates automatic interface cost as reference bandwidth divided by interface bandwidth and selects lower-cost paths. A 10-Gb/s reference bandwidth differentiates the links by assigning a higher cost to 1-GbE than to 10-GbE. Explicitly configuring a higher interface metric on each 1-GbE interface likewise causes OSPF to prefer the lower-cost 10-GbE interfaces.
