33. 33 OSI Model – Open Systems Interconnection Model 2014 LENOVO INTERNAL. ALL RIGHTS RESERVED.  Layer 2 -is Switching Or the connectivity from Layer 1, the Physical Layer.  Layer 3 - is Routing It is also a Boundary from one type of network to another. It is also where VLANs can cross boundaries Therefore you need to have a Layer 3 Switch (or a router) in the network if you want VLAN traffic to cross from one VLAN to another VLAN

34. 34 Networking Terminology 2014 LENOVO INTERNAL. ALL RIGHTS RESERVED. This is the bane of all networking technicians and engineers.!!  What is it? –Is a network protocol that ensures a loop-free topology for any bridged Ethernet local area network.network protocoltopologybridgedEthernetlocal area network –The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them.bridge loopsbroadcast radiation –Spanning Tree Protocol (STP) was originally standardized as IEEE 802.1D, most recently in 802.1d-1998, but superceded as of 802.1d- 2004 in favour of Rapid Spanning Tree Protocol (RSTP).
