QoS Traffic-Type Prioritizations?
Does anyone know where I can find info on which types of traffic would require higher levels of prioritization? I'm trying to determine which of these types of data would require the highest/lowest priorities:
video conferencing, video streaming, call clocking, net mgmt traffic, VOIP, etc.
I don't recall seeing anything at all about video in the Off Cert Guide for SWITCH and my google searching isn't coming up with any kind of hierarchial list of which traffic is more time sensitive.

it's good to know the proper precedence, but the only thing you really need to worry about classifying and prioritizing is user generated traffic
I must not be wording my question properly but I'm trying my best not to violate the NDA. I took the test Monday and I can assure you that knowing which types of data need higher priority and IN WHICH ORDER from highest to lowest priority is a topic worth knowing. I agree that knowing how to configure the QoS settings for the different data types (net traffic) is not needed. Unfortunately I have not been able to find a hierarchial list in any of my study material yet. I've gone back through the Off Cert Guide SWITCH book and this info is not in there.... or I am blind.

What phrase would you search for? I've been looking on Cisco with little luck. The closest thing I have found to being of use is a wiki entry... and last time I mentioned a wiki entry you said how flawed using wiki was.
Anyone know if this stuff is covered in the BCMSN books?
EDIT:
Looks like wiki to the rescue:
