A router receives information about network 192.168.10.0/24 from multiple sources. What will the
router consider the most reliable information about the path to that network?

A.
a directly connected interface with an address of 192.168.10.254/24

B.
a static route to network 192.168.10.0/24

C.
a RIP update for network 192.168.10.0/24

D.
an OSPF update for network 192.168.0.0/16

E.
a default route with a next hop address of 192.168.10.1

F.
a static route to network 192.168.10.0/24 with a local serial interface configured as the next hop

Explanation:
When there is more than one way to reach a destination, it will choose the best one based on a
couple of things. First, it will choose the route that has the longest match; meaning the most
specific route. So, in this case the /24 routes will be chosen over the /16 routes. Next, from all the
/24 routes it will choose the one with the lowest administrative distance. Directly connected routes
have an AD of 1 so this will be the route chosen.
