I think you are safe:
3.2.2 Use a VTP mode that does not propogate vlan information over the
trunks
3.2.3 On the trunks allow only the vlans involved in this secnario.
Now after a very painful experience i had with a prictice lab I believe
the question that needs to be asked is, Does the question say i can pass
all of the vlans used in this secnario across every trunk or is it asking
me to allow only the minimum number of vlans required to obtain universal
connectivity over each of the trunks.
Now your options are:
sw tr all vlan 60,20,10,30,
God Bless America,
May it remain The Land of The Free
and
Home of the Brave.

All,
With the bible in my right hand I pray for all you guys struggling to
get
that Number for any personal reason (money, work, etc).
But today is not for talking a religion topics, but for a Question
about
allowing Vlans over a trunk
This particular mooning, while doing Lab 3 of NMC I've found the
following
"On the trunks allow only the VLAN's involved in this scenario."
Solution show us that, f0/8 is assigned to Vlan 10 and also Vlan
60?? Hmmmm
maybe typo.
Say for example: That you have this task in your Real lab: "Task
tells you
to Restrict the traffic crossing the trunk to the VLANs used", for
sure I
will get 0 for this one, if put other vlans allowed in the trunk, I'm
100%
sure about that
Other question that arises from this particular Allowed Vlan
Situation, is
the should VLAN 1 be allowed in the trunks??? , knowing that even
from the
neighbor switch no one is connected to that VLAN1?.
AFIAK removing Vlan 1 from the dot1q trunk, All Traffic leaving would
be
tagged, so all layer 2 traffic control (CDP;DTP;etc) is going to
leave the
port also with a TAG (just like other vlans traffic passing throe the
trunk), but what is the remote end is not cisco? .- I'm Not looking
for the
Scientific Proof Of The Pre-Existence Of Chickens but some opinions
about
this topic is highly appreciated
By the way, Lab3 NMC for task 3.2.3 should be:
(config)# interface range f0/13 14
(config-range)# switchport encapsulation dot1q
(config-range)# switchport trunk allowed VLAN 30,60
not 10
