Routers A and B have an OC12c and a GE link between them and are running OSPF over both of these links.Which item is correct， assuming the default JUNOS software OSPF metric calculation？（）

There are two equal cost paths between A and B

The GE link is the preferred path between A and B

The OC12c link is the preferred path between A and B

Manual metric assignment must be configured to determine the outcome.
