What is correct regarding policy-based routing?
Policy-based routing (PBR) allows for the implementation of routing decisions based on policies other than the destination address. The actions of a policy can include permitting or dropping traffic. This means that PBR can indeed be used to either route certain traffic differently or drop traffic entirely based on the defined policies. Therefore, the correct statement is that policy actions include routing or dropping traffic.
Page 902 Study Guide: Apply the policy Access config- interface mode on the appropriate interface and apply the policy – always as an inbound policy. In other words, the policy is applied as packets enter the router inbound. This makes sense, correct? The purpose of PBR is to override normal destination- based routing. If you applied the policy outbound on an interface, it would be too late – routing decisions are already made. [Aruba Networks]
Correct Answer: A
For routing you need a L3 port
PBR can only be applied inbound and only to routed interfaces.
A PBR can only be applied inbount and only to routed interfaces.
From ACSP learning book Additionnal Routing Technologies : "Assign the policy INBOUND to an interface (must be a routed interface): - A is correct - B is incorrect because cannot be applied on outbound - C is incorrect because monitoring occured every 5 sec - D is incorrect because action can drop but not permit traffic.
