| 1. | □ | Currently, there are five popular configurations of LAN switches in use. |
| 2. | □ | Shared memory switch stores all incoming packets in a common memory buffer shared by all the switch ports. |
| 3. | □ | A switch based on bus architecture has a dedicated memory buffer for each port. |
| 4. | □ | Transparent bridging is a technology that allows a switch to filter packets on the network. |
| 5. | □ | When a switch sends a packet out to all segments to find a specific node, it is called learning. |
| 6. | □ | The process of connecting the two segments to send the packet is known as forwarding. |
| 7. | □ | To remove older information from the memory, switches use a technique called filtering. |
| 8. | □ | Each time a packet is received from a nod, the timestamp remains the same. |
| 9. | □ | To free up valuable memory resources the entry is erased after a certain amount of time with no activity from the node. |
| 10. | □ | Redundancy provides effective elimination of a single-point failure. |
