Refer to the exhibit. Consider that the main power has just been restored. PC3 issues a broadcast IPv4 DHCP request. To which port will SW1 forward this request?
- to Fa0/1 only
- to Fa0/1, Fa0/2, and Fa0/4 only
- to Fa0/1, Fa0/2, Fa0/3, and Fa0/4
- to Fa0/1, Fa0/2, and Fa0/3 only
- to Fa0/1 and Fa0/2 only
| Explanation & Hint:
Fa0/4 is the incoming port where PC3, which issued the DHCP request, is connected, then the switch will forward the broadcast DHCP request out of all its other active ports except for Fa0/4. This ensures that the request can reach the DHCP server and any other device that needs to hear the broadcast within the VLAN. Given this information, the correct ports that SW1 will forward the DHCP request to are:
The switch will not forward the broadcast to Fa0/4 because that’s the port from which the request originated. Therefore, the correct answer is: to Fa0/1, Fa0/2, and Fa0/3 only |
