An AP using version 7.0 MR1 broadcasts a Layer 3 CAPWAP discovery message on the local IP subnet. Which step does the AP take next?
A.
Determine if the controller responses include the primary controller.
B.
Determine if the controller responses include the master controller.
C.
Send a discovery request using DHCP option 43.
D.
Send a discovery request using DNS.
E.
Send a discovery request using locally stored information on the AP.
F.
Send a discovery request using OTAP.
Explanation:
Send a ‘discovery request’ AFTER broadcasting discovery message…?
Just as a reference:
OTAP is enabled by default in the WLC versions earlier than 4.2.39.13.
It says nothing in the question that it has been enabled so I guess that E is the right answer because that is next in line.
Locally stored controller IP address discovery—If the access point
was previously associated to a controller, the IP addresses of the
primary, secondary, and tertiary controllers are stored in the
access point’s non-volatile memory. This process of storing
controller IP addresses on an access point for later deployment is
called priming the access point.
