Voice Vlans

[IPTdude]

When configuring a switch port for a voice vlan which way should I do it in the Lab.

I have usually used
Switch(config-if)#switchport mode access
Switch(config-if)#switchport acess vlan 5
Switch(config-if)#switchport voice vlan 6

I have seen it configured this way as well:

Switch(config-if)#switchport trunk encap dot1q
Switch(config-if)#switchport mode trunk
Switch(config-if)#Switchport voice vlan 6
Switch(config-if)#switchport trunk native vlan 5

..........

As far as I know, both ways work the same, and both are correct. Will both be acceptable in the exam?

I think both ways are fine, but it depends on the type of phone connecting to the device.

The First example is for phones and switches which support voice-vlans through a static access ports, simply by running 2 vlans on the same port, data and voice.

the second example I think is for older phones which don't support voice vlans, and need dot1q to carry the traffic for both Vlans.. correct me if i'm wrong...

you are correct the second example is for older phones, both work though to the best of my knowledge. The best configuration will depend on other things stated in the exam... since you guys knkow there are multiple ways to do certain things, the best practice for the most part goes out the window. just focus on the questions. read multiple times and don't rush.
