Static routes are best used in stub routing scenarios, where routing paths are straightforward and largely unchanging. They provide increased security and reduced overhead compared to dynamic routing methods. In more complex or dynamic environments like enterprise networks, using static routes can complicate management. ;
Static routes are most effectively used in stub routing scenarios, where routing paths are stable and straightforward. They simplify management while providing efficient operation and added security. Therefore, the best answer to the question is D. Stub routing.
