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.

Subject: Connecting IP Phone 7960 to CAt3550
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
