Leigh, I think your approach of not doing something unless it is specifically asked for is, in general a good philosophy. However one also has to bear in mind that points are only awarded for a working configuration. So to answer the original question, should one enable mls qos and a trust state in order to get a working configuration?
From that perspective I would say both the global configuration of mls qos and the trust state need to be configured for the voice vlan feature to work as intended.

Howdy,
I'd say that this depends on the wording of the exam.
I real life, I use the dchp server to assign vlan and qos values to the
phones, then get the switches to trust those values, as if I need to
change them, I only need to do it in one place.
In the lab, you'll be asked to do something specific. You could either
trust it, rewrite it or do nothing. Personally, I'd do nothing if it
wasn't asked for (or I didn't see it!!)
