A router is configured with multiple static routes. What will happen if a dynamic routing protocol also tries to route traffic to the same destination?

The static route will always take priority

The dynamic route will take priority

The router will enter a routing loop

The router will discard the traffic

The static and dynamic routes will be used in parallel
