What are two reasons why a route might be hidden? (Choose two.)

Route preference dictates which route is chosen among multiple valid paths to a destination, but a lower-preference route is typically stored in the routing table (albeit not active) rather than being 'hidden' for simply not being the best route.

A routing loop describes traffic endlessly circulating due to incorrect routing information, but it does not directly cause routes to be 'hidden' from the routing table; instead, the routes would typically be present but lead to forwarding issues.

If a route's next hop is unreachable or invalid, the route will be hidden from the forwarding table to prevent traffic from being blackholed, indicating a problem in the network's connectivity.

Routing policies are powerful tools that can explicitly hide routes from the routing or forwarding table based on defined criteria, allowing administrators to control route advertisement and installation for traffic engineering or security purposes.
