Spanning Tree Protocol (STP) Which LAN switch method receives the complete frame before beginning to forward it? Switches break up ___________________ domains What is used to prevent switching loops in a network with redundant switched paths?

What are the distinct functions of a Layer 3 router?Simply to say, a layer 3 switch is a network switch with some router functions. The most important purpose of the layer 3 switch is to speed up the data exchange within a large LAN. The routing function is also used for this purpose. It can accomplish one route and multiple packet forwarding processes.
What are Layer 2 and 3 switches?Layer 2 switches perform the switching function to re-arrange the data frames from the source to its destination network. Layer 3 switches define paths based on logical addressing. Layer 2 switches are used to reduce traffic on the local network, whereas Layer 3 switches mostly used to Implement VLAN.
