You probably know OTAP, over the air provisioning of APs. When an access point boots, it can listen to the Air and receive information about controllers from the other APs. Do you want to know what does an OTAP message look like? How to read your controller IP address from a capture?

Imagine... you are in a lab, and the scenario says "your controller blahblah Management IP address was lost. Use the OTAP capture to find it. And basically if you can't find it, you can't get to it and configure it and this means the end of the journey for your lab..." you'd better be able to decipher OTAP messages, just in case!
Disclaimer: I DON'T know if this scenario is part of an actual lab or not! I just feel that at CCIE level, you are probably expected to understand OTAP well enough to know how to use it!
