Static routes remain in the routing table until you remove them or until they become inactive.D. Static routes are learned by neighboring devices and added to their routing tables.
Which statement is true about a forwarding table?() A.It stores a subset of information from the routing table.B.It contains routes learned from all protocols to a destination.C.It provides a database for routes selected and placed into the routing table.D.Every routing protocol maintains its own forwarding table.

pany has a Catalyst 6500 and you need to configure redundancy between the supervisor modules. With route processor redundancy （RPR+）， the redundant supervisor engine is fully initialized and configured， which shortens the switchover time if the active supervisor engine fails. Which three statements are true about the RPR + operations when the redundant supervisor engine switched over the failed primary supervisor engine？ （）A、 Static IP routes are maintained across a switchover because they are configured from entries in the configuration file.B、 Information about dynamic routing states， maintained on the active supervisor engine， is synchronized to the redundant supervisor engine and is transferred during the switchover.C、 Information about dynamic routing states， maintained on the active supervisor engine， is not synchronized to the redundant supervisor engine and is lost on switchover.D、 The Forwarding Information Base （FIB） tables are cleared on a switchover. As a result， routed traffic is interrupted until route tables reconverge.E、 Static IP routes are cleared across a switchover and recreated from entries in the configuration file on the redundant supervisor engine.F、 The Forwarding Information Base （FIB） tables are maintained during the switchover. As a result， routed traffic continues without any interruption when the failover occurs.
