You have a Catalyst 2950 switch with three defined VLANs: VLAN 1, VLAN 3, and VLAN 5. You connect the switch to another switch using the Fa0/1 interface and use the switchport mode trunk command for Fa0/1. Assuming that the other switch has the default configuration, what will now pass through Fa0/1 on the switch? - No traffic. - Traffic in all default VLANs, but not for VLAN 3 or VLAN 5. - Only traffic in VLAN 1. - Traffic for all VLANs defined on the switch.

-Traffic for all VLANs defined on the switch. When you connect two switches, by default, a trunk port is automatically established. Using the **switchport mode trunk** command ensures that trunking will happen between the switches unless the other switch has trunking disabled. Trunk ports carry traffic from all VLANs defined on the switch; no additional configuration is required to enable the switch to send traffic for a specific VLAN.
