Actually, I think the aggregate solution is more correct. An IP Phone will send SCCP keepalives to every CM in its CMG. This would be multiple flows. This bandwidth is negligible, but so is any other SCCP. If the question stated "SCCP traffic," I think you would have to go with an aggregate policer. Correct?
Also, your PC port could be allowed access to the voice VLAN, in which case there could be IP Communicator running on the attached PC. This would be another SCCP flow. Thoughts?

If you're asked to police EACH phone's SCCP, then you could use EITHER an aggregate policer (unique ACL applied to each port), OR a microflow policer (ACL applied to the voice vlan). Correct? The latter requires less configuration (IPExpert solution), but the former can be taken straight out of the SRND. In fact, the ACL naming convention used in the SRND specifies the mod/port. Do both solutions work for this question? Is one preferred over the other? What's the proctor looking for?

And if you have ACL A applied to the port and ACL B applied to the vlan the host device is on, the port ACL supercedes the vlan ACL.

A microflow or aggregate policer applies to the ACL, not to the port or VLAN. For instance, a policer/ACL can be applied to port(s), vlan(s), or combination of vlan(s) and port(s); therefore, the following should hold true: Microflow - polices on a per flow basis originating from any devices on any of to the ports or vlans to which the ACL is applied. Aggregate - polices sum of all traffic originating from any devices on any of to the ports or vlans to which the ACL is applied.
