LAN Design Flashcards
What are the three layers in a LAN Network?
Access, Distribution and Core
What type of layer would an end host typically plug into?
Access Layer
Client access security measure such as Port Security typically happen on this layer
Access Layer
Are Access Layer Switches typically connected to each other?
No, that happens at the Distribution Layer
What layer do Access Layer Switches connect upstream to?
Distribution Layer
What layer do Distribution Layer Switches connect downstream to?
Access Layer
What layer does software policy such as QoS, etc. happen on?
Distribution Layer
True or False - Distribution Layer Switches will typically come in redundant pairs
True
What layer do Distribution Layer Switches connect upstream to?
Core Layer
What layer does the Core Layer connect downstream to?
Distribution Layer
Traffic between buildings on a Campus would flow through what layer?
Core Layer
True or False - You should have software policy such a QoS on Core Layer Switches
False, that will slow down the core layer
What is the Core Layer designed for?
Speed and Efficiency
What is a Collapsed Core?
It’s where the Distribution and Core Layer functions are performed on the same hardware device
