Which configuration option will cause the link between two Cisco 3600 Series Multiservice Platforms to become a functional trunk?
A.
switchport dynamic auto
switchport dynamic auto
B.
switchport access vlan 10
switchport mode dynamic desireable
C.
switchport mode trunk
switchport nonegotiate
D.
Leave both ports with the default trunk settings.
Right is C
Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers
The default is access mode.
Catalyst Switches
The default mode is dependent on the platform; it should be either dynamic auto for platforms that are intended as wiring closets or dynamic desirable for platforms that are intended as backbone switches. The default for PVLAN ports is that no mode is set.

BUT, C is also correct…

B is correct, as default mode (dynamic auto) in both sides will not form a trunk.

C – could be wrong. If nonegotiate is configured the mode of the port can only be either trunking or an access (nonegotiate will not work with the dynamic auto, or dynamic desirable). Because you don’t have enough information on the mode of the port (access or trunk) you can’t make the assumption.
The most correct answer here is D; as the default trunk settings are Dynamic Desirable. But you could argue the merits of C.

… D could be incorrect too as you don’t know the VTP Domain names of each switch. If they are different DTP will not form a trunk.
