QuestionQ44

Routing

Which three actions are necessary to route traffic originating from voice servers over a dedicated Internet link?

Choose three
  • A Create a class-map and attach an ACL with the IP of the next-hop to it.
  • B Create an ACL that selects IPs of voice servers.
  • C Attach a policy to the egress interface.
  • D Create a policy-map and attach the configured class-map and set the next-hop IP.
  • E Create a class-map and attach that ACL.
Explanation

Policy-based routing classifies the traffic with an ACL that matches the voice servers’ source IP addresses, associates that ACL with a class map, and uses a policy map to set the desired next-hop IP address for the matched class. Policy-based routing is applied to arriving traffic, not as an egress policy. Cisco documents that PBR uses match criteria and a resulting action, including a configured next hop, and is enabled on the interface receiving the packets.
