Question
PBF can address which two scenarios? (Select Two)
Options
- Aforwarding all traffic by using source port 78249 to a specific egress interface
- Bproviding application connectivity the primary circuit fails
- Cenabling the firewall to bypass Layer 7 inspection
- Drouting FTP to a backup ISP link to save bandwidth on the primary ISP link

Explanation
Policy-Based Forwarding (PBF) allows traffic to be routed based on criteria beyond the standard routing table, such as application, source/destination, or interface. (B) PBF supports path monitoring with failover, so if the primary circuit fails, traffic is automatically rerouted to a backup link - providing application continuity. (D) PBF can steer specific application traffic (e.g., FTP) to a secondary ISP link to conserve bandwidth on the primary link. (A) While PBF can technically match on source port, using a specific ephemeral high port like 78249 is not a reliable or meaningful real-world PBF use case. (C) Bypassing Layer 7 inspection is controlled by Security policy profiles and decryption policy, not PBF.
