As far as I know,,

First one is used when the phone is providing trunking, don't forget that
Cisco phone is 2 port switch.
Second is used when the 3550 is providing trunking, and you need setup as
trunk mode on the switch.

You need to read the question very carefully on this one.

Hi group,

Studying IPexperts lab 36 I found two solutions for connecting Cisco IP
Phone to cat. Can you explain me the differences and when the
configurations should be used?

Version 1:

interface FastEthernet0/11
 switchport access vlan 102
 switchport voice vlan 101
 switchport trunk encapsulation dot1q
 switchport priority extend cos 0
 no ip address
 mls qos cos 1
 mls qos cos override
 spanning-tree portfast

Version2

interface FastEthernet0/12
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 202
 switchport mode trunk
 switchport voice vlan 201
 no ip address
 spanning-tree portfast
