Selected Answer: A
Ethernet switches that have VLAN enabled use Ethernet frames with the VLAN TAG field added. The VLAN TAG is a 12-bit field that can address up to 4096 VLANs. A switch reads the VLAN tag and forwards the Ethernet frame to the port assigned to the VLAN ID, or to the next switch when required.

answer D = The Tag Protocol Identifier is set to 16 bits. In the CCNA certification it is said that it's not possible to have more than 4096 VLANs
