What action will occur if a switch receives a frame and does have the source MAC address in the MAC table?
- The switch refreshes the timer on that entry.
- The switch shares the MAC address table entry with any connected switches.
- The switch does not forward the frame.
- The switch sends the frame to a connected router because the destination MAC address is not local.
| Explanation & Hint:
It implies that the switch updates the timestamp on the existing MAC address table entry when it receives a frame with a known source MAC address. This refreshes the entry to indicate the most recent time the MAC address was active on the network. |
