Which option prevents the AP from completing the DTLS join process?
I think the certificate has expired as referenced in https://www.networkoc.net/cisco-wlc-bad-certificate-alert-received-from-peer/ the but there is no such option. I think it’s C is closest.
You are right: Factory-installed certificates are referenced with the term “MIC”, which is an acronym for Manufacturing Installed Certificate . In the logs you can see the AP is using this certificate (MIC) and not using SSC
A.
SSC problem or certificate have been expired.

AP had MIC certificate installed. So AP are not using SSC. Therefore A is not correct. There are another dates on console output, so I think C is correct.
