Refer to the exhibit. Why is the 140.140.0.0 network not used as the gateway of last resort even though it is configured first?
Select the best response.
A.
The last default-network statement will always be preferred.
B.
A route to the 140.140.0.0 network does not exist in the routing table.
C.
Default-network selection will always prefer the statement with the lowest IP address.
D.
A router will load balance across multiple default-networks; repeatedly issuing the show ip route command would show the gateway of last resort changing between the two networks.
