Examine the following configuration on Router R1. R1’s show ip route 172.16.4.1 command
lists a route with outgoing interface S0/1/1. Host 172.16.3.3 uses telnet to connect to host
172.16.4.1. What will Router R1 do with the packets generated by host 172.16.3.3 because
of the telnet, assuming the packets enter R1’s F0/0 interface?
(Choose two.)
interface Fastethernet 0/0
ip address 172.16.1.1 255.255.255.0
ip policy route-map Q2
!
route-map Q2 permit
match ip address 101
set interface s0/0/1
!
access-list 101 permit tcp host 172.16.3.3 172.16.4.0 0.0.0.255

A.
The packet will be forwarded out S0/0/1, or not at all.

B.
The packet will be forwarded out S0/0/1 if it is up.

C.
The packet will be forwarded out S0/1/1 if it is up.

D.
The packet will be forwarded out S0/1/1 if it is up, or if it is not up, out s0/0/1.

E.
The packet will be forwarded out S0/0/1 if it is up, or if it is not up, out s0/1/1.

Explanation:
Packets created by Telnet use TCP, so the packet will match ACL 101 with a permit action.
So, PBR will match the only route map clause shown in the configuration, with that permit
route map clause listing a set command. The set command lists S0/0/1 as the outgoing
interface, and without a default parameter. So, Router R1 will first attempt to forward the
packet based on the set command (interface S0/0/1), but if the interface is down, then try to
forward based on the IP routing table (interface S0/1/1).
