Your network contains a server named Server1. Server1 runs Windows Server 2008 R2 and has a
single network connection. The connection is configured to use a default gateway address of
10.0.0.1. The default gateway has a metric value of 100. You configure a second default gateway
that uses an address of 10.0.0.2. You need to ensure that 10.0.0.2 is only used as the default
gateway if 10.0.0.1 is unreachable. What should you do?

A.
For the interface, set the interface metric to 100.

B.
For the 10.0.0.2 gateway, set the metric to 50.

C.
For the 10.0.0.2 gateway, set the metric to 200.

D.
For the 10.0.0.1 gateway and the 10.0.0.2 gateway, enable automatic metric.
