   You have configured FBF on a Junos device to direct traffic from a specific source subnet to a routing instance named 'guest-internet'. After applying the configuration, you notice that traffic from the source subnet is not being forwarded to the 'guest-internet' instance. Which command would you use to verify that the firewall filter is being applied and matching the traffic?

   • Ashow interfaces statistics
   • Bshow firewall filter
   • Cshow firewall log
   • Dshow firewall filter <filter-name>

   • BIt changes the destination IP address of the packet to 192.168.2.1
   • CIt sends the packet to the routing instance named 192.168.2.1

   What is the primary purpose of filter-based forwarding (FBF) in Junos?

   • ATo apply quality-of-service (QoS) policies to traffic based on source and destination addresses
   • BTo select traffic using firewall filter match conditions and forward it to a specific routing instance or next hop
   • CTo filter routing advertisements between peers to control the routing table contents
   • DTo forward traffic based on the destination IP address alone, bypassing the routing table
