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 issue with duplicate client entries from iOS clients with the private MAC address feature enabled can be resolved by breaking the high availability using the cmxha config disable command and upgrading the primary and secondary individually. This approach allows for each appliance to be upgraded without affecting the high availability pair’s synchronization and operation. References: The solution is supported by best practices for upgrading Cisco appliances in a high availability configuration, as outlined in the CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

 The issue described occurs when the fallback feature is disabled on the Cisco AireOS controller. When fallback is disabled, the controller does not attempt to reconnect to the primary TACACS+ server after it becomes available again following a failure. Instead, it continues to use the secondary server until it fails or the controller is rebooted. Enabling fallback would allow the controller to periodically attempt to reconnect to the primary server. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

 To prevent honeypot attacks most efficiently, the wireless network engineer should set the auto containment level to 4 and select the Using Our SSID containment option (D). This configuration allows the system to automatically contain rogue APs that are spoofing the organization’s SSID, which is a common tactic in honeypot attacks. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.
