RE: General Concensus on DTP

I passed the exam and used the following approach to such issues:

I do not configure anything unless Cisco asks me to do so - implicitly
or explicitly.

Here are examples for you:

Task 2.1 Configure an 802.1Q trunk between SW1 and SW2 using Fa0/2.
Ensure that only VLANS from this lab scenario are permitted.

SW1:
interface fa0/2
switchport trunk encap dot1q
switchport mode trunk
switchport trunk allowed-vlan 10,20,30,40,50

Task 2.1 Configure an 802.1Q trunk between SW1 and SW2 using Fa0/2.
Ensure that only VLANS from this lab scenario are permitted. Do not use
DTP.

SW1:
interface fa0/2
switchport trunk encap dot1q
switchport mode trunk
switchport trunk nonegotiate
switchport trunk allowed-vlan 10,20,30,40,50

Remember these important points about the exam:
1 - It is not a "best practices" exam.
2 - While you are typically not penalized for "over-configuration", you
are not gaining anything per se and just wasting time.
3 - Are you still reading this post :-) jeez...

I think i know the answer already but for those that especially went and
passed the exam:

DTP on a dot1q interface explicity said to be a dot1q interface... did
you
disable it with switchport nonegotiate? Or did you leave it on unless
specifically told not to do DTP over the interface?

I have seen it both ways.. is there a general concensus or rule of
thumb. I
would think real world if both endpoints were set to mode "on" you would
disable explicitly all the time.. but the exam is a minimalist approach
so
it could be leave it unless specifically asked to disable.

Nate
