Compare and Contrast Policy-Based Routing (PBR) and Traditional Routing POWERSWITCH-CAMPUS-DEPLOY Practice Questions (Page 1)

Questions 1–5

1. 1application · medium

   A network administrator is troubleshooting a routing issue. The routing table has a route to a destination via OSPF, but traffic to that destination is being sent to a different next hop. The administrator suspects PBR is involved. What should they check first?

   • AReboot the switch to clear any cached PBR entries.
   • BCheck the OSPF neighbor adjacency to ensure the route is valid.
   • CVerify if a PBR policy is applied to the ingress interface of the traffic.
   • DVerify the routing table's administrative distance for the OSPF route.

   What is a key difference in configuration complexity between PBR and traditional routing?

   • APBR requires no additional configuration beyond enabling a routing protocol.
   • BTraditional routing requires more configuration than PBR because it needs a routing protocol.
   • CTraditional routing requires policy definitions to forward packets.
   • DPBR requires defining policies that specify match criteria and next-hop actions.

   A campus switch is being deployed in a high-throughput environment. The administrator plans to use PBR to route traffic from several VLANs to different WAN links. The switch model supports PBR but only in software. What is the most significant concern?

   • APBR will increase the size of the routing table, causing memory exhaustion.
   • BSoftware-based PBR can cause high CPU utilization and increase forwarding latency, potentially impacting all traffic on the switch.
   • CPBR will prevent dynamic routing protocols from updating the routing table.
   • DPBR will cause routing loops because it overrides the routing table.

   How does traditional routing typically scale compared to PBR?

   • ATraditional routing does not scale because it requires a routing protocol.
   • BTraditional routing scales better because it uses simple destination-based lookups.
   • CBoth scale equally because they use the same forwarding hardware.
   • DPBR scales better because it reduces the number of routes in the routing table.

   Why might an administrator choose traditional routing over PBR for a simple network?

   • ATo support policy-based forwarding based on source IP
   • BTo reduce configuration complexity and administrative overhead
   • CTo achieve lower latency for all traffic
   • DTo enable load balancing across multiple paths
