   A university campus network uses Dell SONiC switches. The network team wants to send all traffic from the student dormitory subnet (10.10.0.0/16) to an external content-filtering appliance at 192.168.100.1, while all other traffic continues to use the default gateway. The filtering appliance is reachable via a directly connected interface on the switch. What is the correct approach?

   • ACreate a static route for 10.10.0.0/16 with next hop 192.168.100.1 and apply it globally.
   • BConfigure an access list on the dormitory interface to deny all traffic and add a permit statement for the filtering appliance.
   • CApply a route map to the interface facing the filtering appliance that matches destination IP 192.168.100.1 and sets the next hop to the default gateway.
   • DCreate a route map that matches source IP 10.10.0.0/16, set the next hop to 192.168.100.1, and apply the route map to the interface facing the dormitory subnet.

   After configuring PBR on a Dell SONiC switch, traffic from the matched subnet is still being forwarded via the default route instead of the PBR next hop. The route map and match criteria appear correct. Which command should the administrator use first to verify whether the route map is being hit?

   • Ashow interface Ethernet1
   • Bshow ip route
   • Cshow route-map POLICY
   • Dshow ip policy

   An administrator has a Dell SONiC switch with PBR configured to redirect traffic from VLAN 10 to a firewall. The route map 'FW_PBR' is applied to interface Vlan10. After a recent reboot, the PBR policy is no longer working. The configuration is still present in the running-config. What is the most likely reason?

   • AThe prefix-list used in the route map was deleted.
   • BThe next hop for the PBR policy is not reachable after the reboot.
   • CThe route map was not saved to the startup-config before the reboot.
   • DThe route map was applied to the wrong interface.

   A PBR policy is not working as expected, and traffic is being forwarded according to the normal routing table instead of the policy. What is the most likely first step to troubleshoot this issue in Dell SONiC?

   • AVerify that the next hop is reachable via a connected route
   • BVerify that the route map is correctly applied to the ingress interface
   • CReboot the switch to clear the PBR cache
   • DCheck the routing table for a default route

   A Dell SONiC switch is configured with PBR to redirect traffic from a specific application server (192.168.100.10) to a load balancer at 10.0.0.10. The route map 'APP' matches the source IP and sets the next hop. The administrator wants to verify that the policy is working. Which command should be used to check the match counters?

   • Ashow ip route 10.0.0.10
   • Bshow ip policy
   • Cshow route-map APP
   • Dshow interface counters
