A switch port is configured as an access port in VLAN 10. A frame destined for a device in VLAN 20 arrives on this port. What happens to the frame?

The frame is forwarded untagged as part of the native VLAN.

The frame is dropped because the access port is not a member of VLAN 20.

The frame is forwarded out all trunk ports tagged with VLAN 20.

The frame is tagged with VLAN 20 and forwarded out the access port.

A network administrator is configuring a trunk between two switches. The administrator wants to carry VLANs 10, 20, and 30, but also wants to prevent any other VLANs from traversing the trunk. The administrator runs 'switchport trunk allowed vlan 10,20,30'. What is the effect of this command?

It has no effect unless the port is in trunk mode.

It allows all VLANs except 10, 20, and 30.

It replaces the allowed VLAN list with VLANs 10, 20, and 30, so only those VLANs are allowed.

It adds VLANs 10, 20, and 30 to the existing allowed VLAN list.

A network administrator needs to configure a Cisco switch port as a trunk port. Which interface configuration command accomplishes this?

In the 802.1Q tagging process, where is the VLAN tag inserted in an Ethernet frame?

Between the source MAC address and the EtherType/Length field

Between the preamble and the destination MAC address

At the end of the frame, after the FCS

In the payload area, replacing the first 4 bytes of data
