There would be multiple ways to look at that IMHO. With priority queuing,
you're correct that there's packet counts, but in order to get a percentage
ratio like that we'd also need to look at the average packet sizes.
In your instance, if we assumed same packet sizes, you would be correct.
Well... Almost. You also would either need to use "max-reserved-bandwidth
100" or do something else with class-default. In priority queuing, any
unclassified traffic goes to the normal queue.
So there may be some things to ask the proctor about along the way.

Subject: QOS Conversions
Hello all,
I'm doing section 17 of ipexpert.
And have question about task #7
IPEXPERT-s answer is:
policy-map Priority-Queue-Conversion
class high-q
bandwidth 3000
class medium-q
bandwidth 2000
class low-q
bandwidth 500
!
interface FastEthernet1/0
ip address 10.10.12.2 255.255.255.0
service-policy output Priority-Queue-Conversion !
I don't agree with the bandwidth values in policy-map command.
we are doing conversion from priority-queueing to MQC.
the queue limits in priority-queueing are: 60 40 20.
which let's say make a total of 120 packets.
60 is 50%,
40 is 33%
20 is 12%
so this is what I did:
policy-map PRIORITY
class high-q
bandwidth percent 50
class medium-q
bandwidth remaining percent 33
class low-q
bandwidth remaining percent 12
-------------------------
Please let me know if I'm wrong. maybe I'm doing something really bad with
QoS.
Thank you very much and regards,
