The local area network shown in the figure shown below has two hubs (Y and Z) and two switches (A and X) interconnecting the workstations and servers. What workstations and servers will receive a copy of a packet if the following workstations/servers transmit a message: Workstation 1 sends a message to workstation 4: a. 2, 3, 4, 5, and 6 b. 4, 5, and 6 c. 4 d. 2, 3 and 4 e. all workstations Workstation 2 sends a message to Server 1: a. 1, 3, and server 1 b. server 1 c. 7, 8, and server 1 d. 1, 3. 7, 8, and server l Server 1 sends a message to workstation 6: a. 6 b. 4, 5, and 6 c. 4, 5, 6, 7, and 8 d. 6, 7, and 8 e. all workstations Replace hub Y with a switch in the figure shown below. Now what workstations and servers will receive copy of a packet if the following workstations/servers transmit a message: Workstation 1 sends a message to workstation 7: a. server 1 b. 2, 3, 7, 8, and server 1 c. 1, 2, 3, and server 1 d. 7, 8, and server 1 Workstation 5 sends a message to Workstation 2: a. 2 b. 1, 2, and 3 c. 1, 2, 3, 4, 6 d. 2, 4, 5, and 6 e. all the workstations Workstation 4 sends a message to workstation 7: a. 7 b. 7, 8, and Server 1 c. 4, 5, 6, 7, 8, and server 1 d. all the workstations Server 1 sends a message to workstation 6: a. 6 b. 4, 5, and 6 c. 1, 2, 3, 4, 5, and 6 d. 1, 2, 3, and 6 e. 6, 7, and 8
