Why each option
Direct routes, representing directly connected networks, are given the highest preference by default over all other routing information sources due to their inherent reliability.
BGP (Border Gateway Protocol) routes typically have a lower preference than direct or static routes in a local router's routing table, such as Junos default preference of 170.
RIP (Routing Information Protocol) routes have a relatively low preference compared to direct or static routes, with a Junos default preference of 100.
Direct routes, which are routes to directly connected networks, have the highest preference (lowest administrative distance/preference value) by default in most routing protocols, including Junos, meaning they are always preferred over other route types.
Static routes have a higher preference than most dynamic routing protocols but are still less preferred than direct routes, with a Junos default preference of 5.
Concept tested: Junos route preference (administrative distance)
