Which configuration command allows the ERX Edge Router to perform Unicast Reverse Path Forwarding lookups on all packets received on an IP interface?() A. ip sa-validateB. ip split-horizonC. ip access-routesD. ip filter-options

Which RIP configuration command allows the ERX Edge Router to send Unicast updates to configured neighbors?() A.neighborB.unicast-neighborC.triggered-updateD.passive-interface

Refer to the exhibit. Which statement is co rrect regarding the router configuration shown? () A. The router will rebroadcast any DHCP requests received by this interface out to all interfaces included in the ip helper - address commands.B. The router will rebroadcast any UDP broadcasts received by this interface out to all interfaces included in the ip helper - address commands.C. The router will unicast any DHCP requests received by this interface out to all addresses included in the ip helper - address commands.D. This configuration will not do anything because the ip helper - address command needs to also be applied to the 192.168.23.1 IP address.
