Sure just look for the following gotcha's.
-is pruning going to be used anywhere in the lab?
-is traffic flow by spanning-tree tuning going to be used anywhere in the
lab?
-is etherchannel load balancing change to be used per vlan anywhere in the
lab?
If you really are certain that having ALL vlans on all switches is ok, then
I would go for it to rule out not having a vlan you need somewhere in the
path, which may cost you troubleshooting time later. I feel I am capable of
quickly isolating issues regarding end to end connectivity how are you doing
in your studies? Do you practice on 4 switch labs often?
Thanks,
Joe

Thanks Joseph ,
but if "USE
THE MINIMUM NUMBER OF VLANS ON EACH VTP DOMAIN" is NOT mentioned per the
Question sections --- can we use the practice I mentioned below....

Bad practice, bad idea...
Many labs want discretion in creating vlans, that's part of the the
challenge... get used to these words...
READ EACH SECTION FULLY BEFORE CONFIGURING ANYTHING IN THAT SECTION
If task 1.1 says create 2 vtp domains and I read ahead and see 1.3 said "USE
THE MINIMUM NUMBER OF VLANS ON EACH VTP DOMAIN" I would create the vtp
domains before I do anything and make sure any vlans have not been
learned...
If you have more than 1 vtp domain, you can probably expect to have
different vlans used in each... here is a caveat!
Draw your layer 2 diagram, complete with trunks and router's on a stick,
etc. You may need to create a vlan in a domain just to carry traffic between
a router on a stick and the other vtp domain etc.

Hi Experts,
If Q says configure SW1 and SW2 in VTP DOMAIN A
and
configure SW3 and SW4 in VTP DOMAIN B
Is it a good practice to make all switches in a COMMON DOMAIN ( SAY VTP
DOMAIN CCIE) CREATE VLANS and let it propogate to ALL SWITCHES over TRUNK
......and then change DOMAIN name as per QUESTION.............
In this will the expectation of Q be to have diff vlan in each domain or
just keep domain name diff and database of vlans sync........
