Why each option
The routing database indicates that the port3 default route is preferred due to its lower metric, and a total of eight routes are present in the routing information base.
The port3 default route (0.0.0.0/0 via 10.0.3.1) has a metric of 10, which is lower than the metric of 20 for the port1 and port2 default routes, making it the preferred or 'best' route.
Counting all distinct route entries provided in the routing database exhibit (3 default, 3 directly connected, and 2 static host routes) totals eight entries, which are all present in the routing information base (RIB).
The port3 default route has the *same* administrative distance as other static default routes but a *lower* metric, making it preferable, not higher.
Both port1 and port2 default routes are not simultaneously active in the routing table because the port3 default route has a lower metric and will be chosen as the primary default route.
