IP addressing L2 and L3 Switch Difference What is Etherchannel PPPOE and PPP wan services DNS

Question

Accepted Answer

IP addressing is the method of assigning unique numerical addresses to devices on a network. L2 switches operate at the data link layer, while L3 switches operate at the network layer. Etherchannel is a technology that allows multiple physical links between switches to be combined into a single logical link. PPPOE and PPP are protocols used for establishing WAN connections. DNS is a system that translates domain names into IP addresses.
