- A . True
- B . False

- A . The switch will send a destination unreachable message to the source device
- B . The switch does not find a matching entry in the mac address table, so it will drop the frame
- C . The switch needs to send a request to discover the device with the mac address 5489-98ec-f011
- D . The switch will flood the frame on all ports except the port that received the frame

- A . 2000-2999
- B . 4000-4999
- C . 6000-6031
- D . 3000-3999
If there is an inclusion relationship in the configured ACL rules, it should be noted that the rule numbers of the strict conditions need to be sorted first, and the rule numbers of the loose conditions need to be sorted last, so as to prevent the packet from stopping to continue matching due to hitting the rules of the loose conditions, thereby Rules that make it impossible to hit strict conditions.
- A . True
- B . False
