I'm studing for IPTT test and I'm not quite sure what's the right answer:
A. It tags all packets using the 802.1Q protocol.
B. It supports the native VLAN as well as multiple auxiliary VLANs.
C. It has the appearance of a trunk port supporting only two VLANs.
D. It does not participate in the spanning-tree process for the auxiliary VLAN.
Anyone could tell me the righ answer and the reason? I'm taking the exam this afternoon...
Thanks in advance!
