The correct answer is A.
OBJ-2.2: Static routing is a form of routing that occurs when a router uses a manually configured routing entry, rather than information from dynamic routing traffic. Static routes must be configured and re-routed manually during an issue. Dynamic routing, also called adaptive routing, is a process where a router can forward data via a different route or given destination based on the current conditions of the communication circuits within a system. If dynamic routing was used, the router would have automatically routed the traffic to another link or connection on the network. Hybrid routing is a combination of distance-vector routing. Hybrid routing shares its knowledge of the entire network with its neighbors and link-state routing. If a connection is lost, hybrid routing protocols are dynamic and can adjust the advertised routes automatically. A distance-vector routing protocol requires that a router inform its neighbors of topology changes periodically. A distance-vector protocol is a form of dynamic routing and would automatically adjust when the fiber connection or link is lost.
