Which statement about using the internal DHCP server feature on a Cisco WLC is true?
Click on the arrows to vote for the correct answer
A. B. C. D.B.
The correct answer is B. The DHCP server IP address must be set to the Cisco WLC management interface IP address.
Here is a detailed explanation of each option:
A. DHCP option 43 must be configured on the internal DHCP server. This statement is incorrect. DHCP option 43 is used to specify the IP address of the controller to the access points. It is not required for the internal DHCP server to function properly.
B. The DHCP server IP address must be set to the Cisco WLC management interface IP address. This statement is correct. When using the internal DHCP server feature on a Cisco WLC, the DHCP server IP address must be set to the management interface IP address of the WLC. This is because the WLC will act as the DHCP server for the wireless clients.
C. The internal DHCP server can serve both wireless and wired clients. This statement is partially correct. The internal DHCP server on the WLC can only serve wireless clients. For wired clients, a separate DHCP server will need to be used.
D. Autonomous APs are supported. This statement is incorrect. Autonomous APs are not supported with the internal DHCP server feature on a Cisco WLC. The internal DHCP server can only be used with lightweight access points that are managed by the WLC.
In summary, the correct statement about using the internal DHCP server feature on a Cisco WLC is that the DHCP server IP address must be set to the Cisco WLC management interface IP address.
