Which two statements are true about static routes in the Junos OS? (Choose two.)
The correct answer is B. Static routes must have a next hop defined. C. Static routes remain in the routing table until you remove them or until they become inactive. Static routes in Junos must have a defined next hop and persist in the routing table until explicitly removed or they become inactive.

- CStatic routes remain in the routing table until you remove them or until they become inactive.

Why each option
Static routes in Junos must have a defined next hop and persist in the routing table until explicitly removed or they become inactive.
Static routes can be defined at the global `[edit routing-options]` hierarchy as well as within routing instances, not exclusively at `[edit routing-instances]`.
Static routes inherently require a next-hop IP address or an egress interface to direct traffic towards its destination; without it, the route is invalid and not installed.
Static routes are manually configured and remain in the routing table indefinitely unless an administrator deletes them or if the next-hop becomes unreachable, causing the route to become inactive.
Static routes are not automatically advertised or learned by neighboring devices; they must be manually configured on each device or redistributed into a dynamic routing protocol.
