VTP Pruning

So I'm sitting in an interview today and I'm asked to describe VTP pruning. So I explain trunking and VLAN tagging and pruning packets destined for VLANs that don't exist on a switch and I finish with All the switches must be in Server mode."
Why would I do this? Maybe because my Mcgraw-Hill CCNA Cisco Certified Network Associate Study Guide states, "EXAM WATCH VTP pruning is used on trunk connections to dynamically remove VLANs not active between the two switches. It requires all of the switches to be in server mode." It also mentions in the text that this is the only drawback to VTP pruning.
Their website has no mention of this in the errata.
Any comments?

Well I believe any switch that prunes VTP must be in server mode.. That doesn't mean all of your switches need to be in server mode to function. -

MMmmm let me clarify on this:
1.- VTP prunning is disabled by default.
2.- You technical explanation is good!
3.- You need to enable prunning on the server... then gets enabled on all switches on the domain.... ie: client switches.
4.- VLAN 1 is never prunned!
