Answer is C, Please download http://www.examcollection.com/cisco/Cisco.Acme.640-802.v2011-07-09.by.Collisio.486q.vce.file.html file and downlaod VCE software to open it U will find the more..
VCE’s use to be great but not the testing engine is completely separate from the the test banks, both of which want you to pay for something in order to get the complete package in order to use their materials. When you buy one you expect the complete product but you will be in for a let down. Avoid it if you can, I felt ripped off.

Per VLAN Spanning Tree (PVST) maintains a spanning tree instance for each VLAN configured in the network. It means a switch can be the root bridge of a VLAN while another switch can be the root bridge of other VLANs in a common topology. For example, Switch 1 can be the root bridge for Voice data while Switch 2 can be the root bridge for Video data. If designed correctly, it can optimize the network traffic.
