Company has a Catalyst 6500 and you need to configure redundancy between the supervisormodules. With route processor redundancy （RPR+）， the redundant supervisor engine is fullyinitialized 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 supervisorengine switched over the failed primary supervisor engine？（） ["Static IP routes are maintained across a switchover because they are configured from entries inthe configuration file","Information about dynamic routing states， maintained on the active supervisor engine， issynchronized to the redundant supervisor engine and is transferred during the switchover","Information about dynamic routing states， maintained on the active supervisor engine， is notsynchronized to the redundant supervisor engine and is lost on switchover","The Forwarding Information Base （FIB） tables are cleared on a switchover. As a result， routedtraffic is interrupted until route tables reconverge","Static IP routes are cleared across a switchover and recreated from entries in the configurationfile on the redundant supervisor engine","The Forwarding Information Base （FIB） tables are maintained during the switchover. As aresult， routed traffic continues without any interruption when the failover occur"]
