Explain:Store-and forward switching accepts the entire frame and performs error checking using CRC before forwarding the frame. What is the reason for this? the sophistication of the encapsulation method applied to the data, the bandwidth of the WAN connection to the Internet, the reliability of the gigabit Ethernet infrastructure of the backbone. to indicate the correct router interface that should be used to forward a segment, to identify which switch ports should receive or forward the segment, to determine which Layer 3 protocol should be used to encapsulate the data, to allow the receiving host to assemble the packet in the proper order. The information is placed by LLC in the frame and identifies which network layer protocol is being used for the frame. As a rule, you have very little or no control on how a packet gets from point A to point B. Either the destination device or the default gateway will respond with its MAC address, which enables the sending node to assemble the frame. The administrator must connect via the console port to access global configuration mode. Peer-to-peer (P2P) networks have two or more network devices that can share resources such as printers or files without having a dedicated server. 219.
