You are troubleshooting a controller-based AP that is unable to locate the controller. DHCP is not usedand the controller is located at 10.10.10.81/24 while the AP is on the 10.10.16.0/24 network. What shouldbe inspected to verify proper configuration

Domain Name System (DNS).

Explanation:

A Domain Name System (DNS) can be defined as a naming database in which internet domain names (website URLs) are stored and translated into their respective internet protocol (IP) address. This simply means that, a DNS is used to connect uniform resource locator (URL) or web address with their internet protocol (IP) address.

A domain name, also known as a uniform resource locator (URL) is a unique web address of a website or an online resource such as a document e.g

In this scenario, you are troubleshooting a controller-based access point (AP) that is unable to locate the controller. DHCP was not used and the controller is located at 10.10.10.81/24 while the AP is on the 10.10.16.0/24 network.

Since the dynamic host configuration protocol (DHCP) was not used, the alternative system to use in order to verify a proper configuration would be to inspect the domain name system (DNS).

This ultimately implies that, if the domain name for the controller and the access point are well translated to their respective IP network address, then the configuration is valid and done properly.

well you didnt give us any options it looks like so im going to go with because cash cant be traced.
