RP/0/RSP0/CPU0:PE7#
After reviewing present router configuration CE7 .which two statements are correct regarding behavior of the "IIq" policy-map?

A. Traffic matched by the "cisco1" class-map will be assigned to the priority queue.
B. The "IIq" QoS policy is applied to the gi0/0 interface in the output direction.
C. Traffic matched bythe"cisco2" class-map has a maximum bandwidth of 30%.
D. Traffic matched bythe"cisco3" class-map has no priority and has a minimum bandwidth guarantee of 20%.
E. There are no packets being matched by the "class-default" traffic class in the "IIq" policy.

You will notice that "cisco1" class map is assigned to the priority queue (the command is configured under policy-map llq class cisco1 priority xxx)
"cisco2" class map: is indeed configured using bandwidth 30%, however that defines the minimum bandwidth but not the maximum.
"cisco3" class map: is indeed configured using "bandwidth 20%", No priority configured and that will define the minimum guaranteed bandwidth.
The last choice is wrong! check under "show policy-map interface" There are 4 or more packets being matched by the "class-default" traffic class in the "IIq" policy.
Class-map: class-default (match-any)
4 packets, 968 bytes
