An understanding of the following key
points should have been achieved:
- The history and function of shared,
half-duplex Ethernet
- Collisions in an Ethernet network
- Microsegmentation
- CSMA/CD
- Elements affecting network performance
- The function of repeaters
- Network latency
- Transmission time
- The basic function of Fast Ethernet
- Network segmentation using routers,
switches, and bridges
- The basic operations of a switch
- Ethernet switch latency
- The differences between Layer 2 and
Layer 3 switching
- Symmetric and asymmetric switching
- Memory buffering
- Store-and-forward and cut-through
switchings
- The differences between hubs, bridges,
and switches
- The main functions of switches
- Major switch frame transmission modes
- The process by which switches learn
addresses
- The frame-filtering process
- LAN segmentation
- Microsegmentation using switching
- Forwarding modes
- Collision and broadcast domains
