lq2
CE7#
RP/0/RSP0/CPU0:PE7#
On CE7 which statement is correct regarding Traffic the QoS policy applied to the gi0/0 interface in the input direction?

A. Traffic matching the "MARKING2" class-map will be marked with qos-group 5
B. Traffic matching the "MARKING1" class-map will be marked with MPLS EXP 5
C. All incoming packets not matched bythe"MARKING1" class-map will be dropped
D. All incoming packets with the DSCP EF marking with be marked with MPLS EXP 0

Issue: show policy-map interface gi0/0
First find out which policy-map is applied (it called something like QOSPOLICY1) A is wrong.
Class MARKING2 is indeed defined but not applied to that policy-map.
There are two class-maps applied MARKING1 and class-default. Both will mark the traffic with MPLS EXP values.
default:
set mpls experimental imposition 0
MARKING1
set mpls experimental imposition 5
