 mDNS has specific restrictions regarding its configuration. Option C is correct because mDNS is not supported on FlexConnect APs with a locally switched WLAN, which limits its deployment in certain network designs. Option D is also correct; the controller software must be newer than version 7.0.6 to support mDNS features, which means that older controller software versions do not have the necessary capabilities to handle mDNS. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

Protocol Independent Multicast (PIM) sparse mode and dense mode are two different multicast routing mechanisms. Sparse mode uses distribution trees and is designed for networks where multicast groups are sparsely distributed across the network, minimizing unnecessary traffic. In contrast, dense mode floods the network with multicast traffic and then prunes back the branches where there are no interested receivers, which can lead to inefficient use of bandwidth. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The wireless client cannot reach the RUN state because it is not receiving an IP address. This is a crucial step in the connection process, as a valid IP address is necessary for the client to communicate on the network. Without it, the client cannot achieve the RUN state, which indicates full authentication and association.

 In passive fallback mode for RADIUS, when the primary RADIUS server fails, the controller will start using the secondary RADIUS server. The default timer settings include an inactive timer, which, upon expiration, prompts the controller to attempt to send RADIUS requests back to the primary server. If the primary server is responsive, the controller will resume sending requests to it. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
