   What is the primary characteristic that distinguishes policy-based routing (PBR) from traditional destination-based routing?

   • APBR is only used for load balancing and cannot enforce security policies.
   • BPBR uses the routing table as the only source for determining the next hop.
   • CPBR selects the next hop based on policies that can consider attributes other than the destination IP address.
   • DPBR forwards packets based solely on the destination IP address in the routing table.

   A campus network uses OSPF for internal routing and has a PBR policy that sends traffic from a specific server to a backup link. The backup link goes down. What happens to the traffic from that server?

   • AThe traffic automatically uses the routing table and is forwarded via OSPF routes.
   • BThe switch sends an ICMP redirect to the server to use a different next hop.
   • CThe traffic continues to be sent to the backup link's next hop, which is unreachable, causing packet loss.
   • DThe PBR policy is automatically removed from the configuration.

   What is a key advantage of traditional routing over PBR in terms of simplicity?

   • ATraditional routing allows forwarding based on source IP address.
   • BTraditional routing requires no routing table.
   • CTraditional routing provides predictable forwarding based on destination address.
   • DTraditional routing automatically load balances traffic across all paths.

   A campus network has a video surveillance system that generates large amounts of traffic. The administrator wants to send this traffic to a storage network on a separate VLAN, bypassing the core router. What should they configure?

   • AA PBR policy that matches the surveillance traffic (e.g., by source IP or VLAN) and sets the next hop to the storage network's gateway.
   • BA policy on the storage network's switch to accept traffic from any source.
   • CA static route for the storage network's subnet pointing to the core router.
   • DA VLAN ACL that permits surveillance traffic to the storage network.

   A campus network has two internet links with different bandwidth and cost. The administrator wants to send large file transfers (identified by destination port) to the cheaper link, while all other traffic uses the primary link. The switch supports PBR with hardware offload. What is the most effective way to implement this?

   • ACreate a static route for the destination subnet of the file transfers pointing to the cheaper link.
   • BUse policy-based routing on the egress interface to redirect all traffic to the cheaper link.
   • CConfigure PBR to match the destination port and set the next hop to the cheaper link, while leaving other traffic to the routing table.
   • DConfigure the routing protocol to prefer the cheaper link for all traffic.
