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.
an OSPF update for network 192.168.0.0/16
B.
a static route to network 192.168.10.0/24
C.
a static route to network 192.168.10.0/24 with a local serial interface configured as the next hop
D.
a RIP update for network 192.168.10.0/24
E.
a directly connected interface with an address of 192.168.10.254/24
F.
a default route with a next hop address of 192.168.10.1
Each router knows about its directly connected networks from its assigned addresses and masks.
Subnets directly connected to a router interface are added to the router’s routing table. Interface has to have an IP address configured and both interface status codes must be in the “up and up” state. A router will be able to route all packets destined for all hosts in subnets directly connected to its active interfaces.

The router considers the most reliable information about the path (the best route) based on Administrative Distance (AD).
In general, the AD number defines the reliability of a routing protocol. A directly connected interface has an AD of 0 which is best so it is always chosen first.
