Which two describe frame tagging?
A.) Examines particular info about each frame
B.) A unique ID placed in the header of each frame as it
traverses the
switch fabric
C.) A user- assigned ID defined to each frame
D.) The building of filter tables
Answer / guest
Answer: B C
Frame identification (frame tagging) uniquely assigns a
user-defined ID
to each frame. This technique was chosen by the IEEE
standards group
because of its scalability.
In this approach, a unique user-defined identifier is placed
in the
header of each frame as it's forwarded throughout the switch
fabric. The
identifier is understood and examined by each switch prior
to any
broadcasts or transmissions to switch ports of other
switches, router,
or end-station devices. When the frame exits the switch
fabric, the
switch removes the identifier before the frame is
transmitted to the
target end-station.
The following points summarize frame tagging:
Used by Catalyst 3000 and 5000 series switches
Specifically developed for multi-VLAN, inter-switch
communication
Places a unique identifier in the header of each frame
Functions at layer 2
Requires little processing or administrative overhead

What are four ways that Fast Ethernet compares to 10BaseT Ethernet? (Choose four) A. Fast Ethernet uses the same Maximum Transmission Unit (MTU) B. Fast Ethernet is based on an extension to the IEEE 802.3 specification C. Fast Ethernet uses the same Media Access Control (MAC) mechanisms D. Fast Ethernet preserves the frame format that is used by 10BaseT Ethernet E. Fast Ethernet errors a speed increase one hundred times that of the 10BaseT Ethernet
