CCNA Test Question

If two switches; both have the same VLAN information, and both switches have devices attached from each VLAN. If the Switches are attached via port F0/1 and F0/1 an one end is changed to and access port on one of the switches, what info if any will pass over the connection? I know that the there has to be a trunk between the switch and the router to route the VLANs but I am unsure what effect the connection between the two switches being changed to access on one end has on the information being passed.

Switch 1
Vlan 1

Vlan 10  Ports f0/2 - f0/12

Vlan 20  Ports f0/13 - f0/24

Switch 2
Vlan 1

Vlan 10  Ports f0/2 - f0/12

Vlan 20  Ports f0/13 - f0/24

If one end changes to access mode ,for example Sw2 ,fast0/1 changed to Access ,then this port needs a Vlan ID with this command ,switchport access vlan x , so the result will be misconfiguration for the port ,but if you mention special vlan for example vlan 2 for that port and other side (usually by default is "Dynamic Desirable" ) goes to make access ,both will be in access mode.

The answer based on your question is : No ,it is not possible to pass the traffic even based on same vlan because you have misconfiguration.

I worded my question poorly. I know the valn data will only pass on trunk links.

I want to know if in the given scenario  A device on Vlan 2 on Switch 1 will  be able to communicate with a device on Switch 2 in VLan 2?
