Q

Borderless Design Principles (w/def)

A
  1. Hierarchical - defining the role of each device at every tier clearly.
  2. Modularity - allows for seamless expansion and integrated services on-demand
  3. Resiliency - making sure the network is always up and accessible - fault tolerance
  4. Flexibility -allows spreading the traffic load over all network resources.

Q

Three Layers of Tiered Borderless Network (w/def)

A
  1. Access - “edge” of network ; responsible for controlling access to and from network
  2. Distribution - interfaces between access and core layers; allows use of intelligent switching and interaction with larger scale network segments.
  3. Core - network backbone

Q

Three Types of Switch Configurations (w/def)

A
  1. Fixed Configuration Switches - switches whose capabilities are all built-in and non-changeable
  2. Modular Configuration Switches - switches whose capabilities are expandable by use of extra modules.
  3. Stackable Configuration Switches - switches that can be interconnected with each other and effectively operate as one large switch.

Q

frame forwarding

A

The process of how a device passes frames through the network; LAN switches maintain table that determines where frames are sent;

Q

content addressable memory (CAM) table

A
  1. Also known as MAC address table.
  2. Table where the MAC address of all members of the network are stored to allow for reliable and timely frame forwarding

Q

Store and Forward Switching

A

Receives entire frame and checks for errors before forwarding it to its destination.

Q

Two Features of Store and Forward Switching

A
  1. Error Checking - drops error frames.
  2. Automatic Buffering - Good for different speed ports.

Q

Cut Through Switching

A

Starts forwarding a frame as soon as its destination MAC is determined.

Q

Two Methods Used in Cut-Throw Switching

A
  1. Rapid Frame Forwarding - will forward error frames to other network segments.
  2. Fragment Free - waits for collision window (64 bytes) to pass before forwarding frame; provides more error checking than standard cut-through
17
Q

collision domains

A

Network segments that share the same bandwidth between devices.

18
Q

Broadcast Domain

A

Collection of interconnected switches.
