Thanks to GroupStudy member Elias Chari for pointing out an error in the
explanation. The ip policy route-map command under the interface will
effect ingress traffic - not egress as the explanation stated.
LAST WEEK'S ANSWER:
Answer: b
Topic Domain: 4d
Issues:
What is the result of this policy-based routing configuration? How will
the traffic described in the question be routed?
Solutions:
Notice there are two policy-based routing configurations present in this
configuration. One of the configs is assigned under the serial 1/0
interface. This policy will effect traffic exiting this interface and is
only relevant for traffic that was not sourced by this local router. The
other policy is assigned in global configuration mode and is relevant
for traffic locally sourced. This question describes locally sourced
traffic and as such, the next hop will be the local PBR configuration of
172.16.100.100.
