A static route is a route you configure by hand. Static routes are predictable, use no bandwidth or CPU for route updates and reveal nothing to neighbours, so they suit small networks, stub sites with a single exit, and backup paths. Their weakness is that they do not adapt: if the topology changes, you must change them yourself, and a mistake is easy to miss until traffic fails. The CCNA expects you to write, read and troubleshoot them for both IPv4 and IPv6.
