   A switch has just been rebooted and the MAC address table is empty. A host with MAC address 00:11:22:33:44:55 sends a frame to another host with MAC address 66:77:88:99:AA:BB on the same VLAN. What will the switch do with the frame?

   • AFlood the frame out all ports in the VLAN except the receiving port, and learn the source MAC address.
   • BSend the frame to the router for forwarding.
   • CDrop the frame because the destination MAC is not in the table.
   • DForward the frame only to the port where the destination is expected to be connected.

   • BThe trunk link between the switches is not allowing the VLAN used by the PCs.
   • CThe default gateway is not configured on the PCs.

   A hospital is deploying a new IP-based nurse call system. The system uses multicast for alerts and must be isolated from general patient Wi-Fi. The network has a single Cisco switch stack. The nurse call system also requires a separate management VLAN for its controllers. Which design should the administrator implement?

   • ACreate a single VLAN for both nurse call and management traffic.
   • BCreate a dedicated VLAN for the nurse call system, assign its ports to that VLAN, and configure a separate management VLAN for the controllers.
   • CPlace the nurse call system in the same VLAN as patient Wi-Fi and rely on multicast filtering.
   • DUse the default VLAN 1 for the nurse call system and a voice VLAN for management.
