   What mechanism can PBR use to handle link failures?

   • AUsing a static route as a backup for all traffic.
   • BRelying on the routing protocol to automatically update the PBR policy.
   • CPBR does not support any form of redundancy.
   • DTracking the availability of a next hop and using a fallback policy if it becomes unreachable.

   Which statement accurately describes the relationship between policy-based routing (PBR) and the routing table?

   • APBR only applies to packets that have no matching route in the routing table.
   • BPBR is a routing protocol that updates the routing table with new routes.
   • CPBR always uses the routing table to determine the next hop for all packets.
   • DPBR can override the routing table for packets that match its defined policies.

   A campus network uses OSPF to exchange routes with a neighboring network. The administrator wants to ensure that all traffic to a specific external network uses a particular path. What is the most appropriate method?

   • ACreate a static route for the external network with a higher administrative distance.
   • BConfigure PBR to match the destination IP and set the next hop to the desired path.
   • CAdjust the OSPF metrics to influence the routing table and let traditional routing forward the traffic.
   • DUse a policy on the neighboring router to redirect traffic.

   A network administrator is planning to implement PBR to route traffic from a specific application to a dedicated link. They are concerned about the ongoing management overhead. What is a key consideration?

   • APBR policies automatically adapt to network changes through routing protocols.
   • BPBR reduces management overhead because it eliminates the need for routing protocols.
   • CPBR policies must be manually updated if the application's IP addresses or the link's next hop changes.
   • DPBR requires no additional configuration once the policy is applied.

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

   • APBR automatically adapts to network changes without configuration.
   • BPBR provides granular control over forwarding based on multiple packet attributes.
   • CPBR provides simpler and more predictable forwarding decisions.
   • DPBR eliminates the need for routing protocols.
