問題 #234
When DHCP snooping is configured on a device, if the number of users to go online exceeds the maximum number of DHCP snooping binding entries supported by the device, the excess users cannot go online.

答案：A

解題說明：
DHCP snooping is a Layer 2 security feature that protects networks against unauthorized DHCP servers and certain DHCP-related attacks.
When DHCP snooping is enabled, the device learns DHCP binding information from legitimate DHCP exchanges.
A binding entry typically records the client ' s IP address, MAC address, VLAN ID, access interface, and lease information.
Huawei devices have a maximum capacity for dynamically learned DHCP snooping binding entries.
If the number of users reaches this capacity, the device cannot create additional bindings for new clients.
Consequently, new users may be unable to obtain IP addresses and access the network.
Huawei also supports configuration of maximum user limits through the dhcp snooping max-user-number command.
The behavior described in the question is therefore correct.


問題 #235
OSPF supports area authentication and interface authentication. If both authentication modes are configured, Interface authentication takes preference over area authentication.
