Which interface types are assigned to IEEE 802.1Q VLANs?

The correct answer is B. Layer 2 subinterfaces. IEEE 802.1Q is the standard for VLAN tagging on Ethernet frames. In PAN-OS, Layer 2 subinterfaces are created on a physical Layer 2 interface and each subinterface is assigned a specific 802.1Q VLAN tag. These subinterfaces are then assigned to VLAN objects for Layer 2 switching.

Explanation

IEEE 802.1Q is the standard for VLAN tagging on Ethernet frames. In PAN-OS, Layer 2 subinterfaces are created on a physical Layer 2 interface and each subinterface is assigned a specific 802.1Q VLAN tag. These subinterfaces are then assigned to VLAN objects for Layer 2 switching. Tunnel and loopback interfaces are logical interfaces with no physical link and do not use 802.1Q tagging. Layer 3 subinterfaces also support 802.1Q tags but are used for routing (inter-VLAN routing), not for membership in a VLAN switching domain.
