How does a router uses a routing table to determine over which path to send a packet? |
| | A) | The first line in the routing table is used if the path is available; otherwise the router tries the next line down, and so on. |
| | B) | The last line in the routing table is used if the path is available; otherwise the router tries the next line up, and so on. |
| | C) | After examining all rows in the routing table, the router sends the packet along the path with the highest metric. |
| | D) | After examining all rows in the routing table, the router sends the packet along the path with the lowest metric. |
