Scenario:
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
Explanation:
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
