[10 points] If Workstation-A sends a frame to Workstation-B. The Switch, with the * empty switch table, will forward the frame to which host (or hosts)? Workstation-D [10 points] If Workstation-A sends a frame to Workstation-B. The Switch, with the switch table populated as shown, will forward the frame to which host (or hosts)? Workstation-B Workstation-C Workstation-D [20 points] In the scenario pictured below: Host A is on the same local network as Host B. Host A knows the IP address of Host B and needs to send a datagram to host B. However, B's MAC address not in A's ARP table. Describe how host A uses ARP to find B's MAC address. In the scenario pictured below: Host C is communicating with Host D through the Router R. The frame is about to be sent out over the wire from the source Host C.
