I know there have been many, hopefully you have enough patience for one more.

In going through various practice exam engines, I've noticed that their simulation questions many times restrict you to one and only one path. Anything you try to execute that isn't part of their pre-canned answer comes up as an "invalid command". In a scenario for configuring inter vlan routing using sub-interfaces for instance, I've gotten into the habit from the simulation labs of removing the ip address from the interface and making sure it is up as part of the configuration routine for the sub-interfaces.
Router#configure terminal
Router#(config)#interface fastethernet 0/1
Router#(config-if)#no ip address
Router#(config-if)#no shutdown
Router#(config-if)#interface fastethernet 0/1.2
Router#(config-subif)#encapsulation dot1q 2
Router#(config-subif)#ip address 10.1.2.1 255.255.255.0
Router#(config-subif)#exit
Router#(config-if)#interface fastethernet 0/1.3
Router#(config-subif)#encapsulation dot1q 3
Router#(config-subif)#ip address 10.1.3.1 255.255.255.0
Router#(config-subif)#
In the practice test, the magenta colored commands shown came back as invalid and the answer was scored wrong.
I'm not sweating the practice exams as I know what's going on and can determine whether what I'm doing is right or wrong, but can anyone confirm or deny whether the 802 exam sims would let this type of "supplemental" configuration be included without failing the answer?
I tend to include things by habit if it can possibly prevent a conflict and hearing something I know to be ok is "invalid" makes me second guess and slows me down.
Thanks
