If data is being sent ver a wireless netwrk, then cnnects t an Ethernet netwrk, and eventually cnnects t a DSL cnnectin, which header will be replaced each time the data travels thrugh a netwrk infrastructure device? Layer 3 data link physical Layer What best describes the destinatin IPv4 address that is used by multicasting? a single IP multicast address that is used by all destinatins in a grup an IP address that is unique fr each destinatin in the grup a grup address that shares the last 23 bits with the surce IPv4 address a 48 bit address that is determined by the number f members in the multicast grup 19. In an Ethernet netwrk, when a device receives a frame f 1200 bytes, what will it d? drp the frame prcess the frame as it is send an errr message t the sending device add randm data bytes t make the frame 1518 bytes lng and then frward it 20.

5 surce IP address destinatin MAC address Ethernet type destinatin IP address 21. What will a Layer 2 switch d when the destinatin MAC address f a received frame is nt in the MAC table? It initiates an ARP request. It bradcasts the frame ut f all prts n the switch. It ntifies the sending hst that the frame cannt be delivered. It frwards the frame ut f all prts except fr the prt at which the frame was received. 22. What are tw features f ARP? (Chse tw.) If a hst is ready t send a packet t a lcal destinatin device and it has the IP address but nt the MAC address f the destinatin, it generates an ARP bradcast. An ARP request is sent t all devices n the Ethernet LAN and cntains the IP address f the destinatin hst and its multicast MAC address. When a hst is encapsulating a packet int a frame, it refers t the MAC address table t determine the mapping f IP addresses t MAC addresses. If n device respnds t the ARP request, then the riginating nde will bradcast the data packet t all devices n the netwrk segment. If a device receiving an ARP request has the destinatin IPv4 address, it respnds with an ARP reply. 23.
