Hi,
I'm making a guess with my limited knowledge, hoping that more
knowledgeable will correct me...
My answer: C.
a. Not true. If frames are getting around without
many errors other than leaking, duplex mode must
be fine.
b. This, itself is not a sufficient reason for frame
leaking. 802.1q is capable to trunking the frames
just right.
c. This could be possibly the cause. Must be using FDDI.
SAID field is used specifically for identifying the VLAN.
Messing this could cause frames intended for one VLAN to
leak into another.
d. & e. Native VLAN information can be different at
the two ends of a trunk if the two switches are
serving two different VLANs.
