Scenario:
After reviewing present router configuration CE7. which two statements are correct regarding behavior of the “IIq” policy-map? (Choose 2)
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
Correct Answer: AD
Explanation/Reference:
You will notice that “cisco1” class map is assigned to the priority queue (the command is configured under policy-map IIq 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
