## By default, what is the OSPF cost for any link with a bandwidth of 100 Mb/s or greater?

- 1
- 100
- 10000
- 100000000

**Answers Explanation & Hints:**OSPF uses the formula: Cost = 100,000,000 / bandwidth. Because OSPF will only use integers as cost, any bandwidth of 100 Mb/s or greater will all equal a cost of 1.
