What is the purpose of the stp protocol?

-The STP protocol allows switches to have redundant connections, while avoiding problems associated with switching loops. For example, if there is a switching loop, a broadcast would go around in circles indefinitely.-The spanning tree protocol is a networking method used to prevent feedback on a network divided into sections and joined by several bridges.What is the purpose of VTP pruning?

-VTP pruning allows the switch to not forward user traffic for VLANs that are not active on a remote switch. This feature dynamically prunes unneeded traffic across trunk links. If the VLAN traffic is needed at a later date, VTP will dynamically add the VLAN back to the trunk

What is the purpose of a vlan?

-VLAN's allow more than one layer-2 network to exist on a switch. When trunking between switches, it also allows hosts on different switches to be in the same layer-2 network.-Virtual local-area networks (VLANs) are a switching technology used to improve network performance by separating large broadcast domains into smaller ones.
