*1.Which two statements about frame tagging are true? (Choose two )
A.A filtering table is developed for each switch
B.Frame tagging assigns a unique user defined ID to each frame
C.A unique identifier is placed in the header of each frame as it is forwarded
between switches
D.Frame tagging is a technique that examines particular information about
each frame based on user defined offsets
Answer:B,D
*2.Which two statements about the store and forward switching
method are true? (Choose two )
A.Latency remains constant regardless of frame size
B.Latency through the switch varies with frame length
c.The switch receives the complete frame before beginning to forward it
D.The switch checks the destination address as soon as it receives the header
and begins forwarding the frame immediately
Answer:B,C
