802.1Q encapsulation is compatible with which models of switches?

802.1Q encapsulation is compatible with which models of switches?

• A. All models
• B. Only core switches
• C. Only router models
• D. Only managed switches

Answer: (A)

802.1Q tagging is a standard for carrying VLAN information on Ethernet frames. Because it’s a universal standard, any switch that supports VLANs will understand and forward 802.1Q tagged frames. This means it isn’t limited to core devices, routers, or managed switches—both unmanaged and managed switches that implement VLANs can handle 802.1Q. In modern networks, this compatibility is essentially across all relevant switch models; only very old, non-VLAN-capable gear would be an exception.
