Most preferred route? 1) Directly Connected Route 2) Static Route 3) Dynamic Route 4) None

That depends upon your needs,

Static route is the most simplest,but some times you will have to configure your routers with any kind of dynamic protoclos

Directly connected Route

The lowest metric is the best route.

Dynamic route is best route, But the main route depends upon the priority of links, hop count and etc

Direct Connected

DYNAMIC Route

Direct connected .

connected has higher priority followed by static and then the rest routing protocol with their prorities.

directly connected route because it has the lowest metric of0

is direct  route

Most preferrable route is Directly connected metric is0

The most preferred route by default for cisco routers is a directly connected link(interface) then static route.

It Depends on many factors

First one: whatever the route is directly connected or static, the most netmask matches will be prefered

Example:

If i hace10.10.10.0/24 directly connected, and i have10.10.10.10/32 is comming from dynamic protocol, then the traffic will go to the host from dynamic routing protocol not go to the host with direclty connected.

Second Thing: There is many table above routing table decide the routing decision like Policy Based Routing and VRF which are prefered on any routes on the routing tables.

Third thing: Decision based on Administrative distabce and metrics.
