[All CWNA-109 Questions]

Option 43 must be configured to allow access points to locate controllers. In what network service should this option be configured?

Show Suggested Answer Hide Answer
Suggested Answer: C

DHCP (Dynamic Host Configuration Protocol) is the network service where option 43 must be configured to allow access points to locate controllers. DHCP is a protocol that allows a device to obtain an IP address and other network configuration parameters from a server. In a wireless controller scenario, the access points can use DHCP to request an IP address from a DHCP server, which can also provide the IP address or hostname of the wireless controller as an option in the DHCP response. Option 43 is a vendor-specific option that can be used to encode custom information for different types of devices. For example, Cisco access points can use option 43 to receive the IP address of the wireless controller from the DHCP server, while Aruba access points can use option 43 to receive the hostname of the wireless controller from the DHCP server.This way, the access points can discover the wireless controller and establish a connection with it.Reference:1, Chapter 8, page 309;2, Section 5.2

I've got a good feeling about C. DHCP is where you'd configure network settings like this for access points.

I'm gonna have to go with the classic DHCP on this one. Although, I do wonder if the correct answer is actually 'the Matrix'.

I'm feeling confident it's C) DHCP. If the access points need to locate the controllers, that's gotta be in the network configuration, not in something like LDAP or RADIUS.

DHCP sounds logical, but I'm kinda leaning towards RADIUS. Isn't that where you manage access and permissions?
