Correct. Answer is B (UDP) Prior to release 8.0, ICMP ping is used to heart-beat with the peer WLC over the Redundancy Management Interface. As part of this feature for release 8.0, ICMP ping is replaced with a UDP message. https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/7-5/High_Availability_DG.html#pgfId-91515
