 Link-Local Service (LSS) filtering for mDNS (Multicast Domain Name System) is used to control the propagation of mDNS services across the network. To enable LSS for the AppleTV mDNS service only when ORIGIN is set to Wired, the correct action is to set ORIGIN to Wired and enable LSS specifically for the AppleTV service. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 The two protocols used to communicate between the Cisco Mobility Services Engine (MSE) and the Cisco Prime Infrastructure network management software are HTTPS and NMSP (Network Mobility Services Protocol). HTTPS is used for secure web-based communications, while NMSP is a Cisco proprietary protocol used specifically for efficient, real-time communication between MSE and network management software like Cisco Prime Infrastructure. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

When upgrading a Cisco AireOS WLC from version 7.3 to 8.9, it’s crucial to configure ACLs that allow necessary traffic for Cisco Central Web Authentication (CWA). The correct ACLs to configure are:

• B. Permit 0.0.0.0 0.0.0.0 UDP DNS any: This ACL allows DNS queries from any source to any destination, which is essential for resolving domain names during the upgrade process.
• E. Permit 0.0.0.0 0.0.0.0 UDP any any: This ACL permits all UDP traffic from any source to any destination, ensuring that services relying on UDP can continue to function during the upgrade.

These ACLs ensure that critical services like DNS resolution are not interrupted during the upgrade process, which could otherwise lead to system instability or failure to access network resources. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )
