 The correct configuration for limiting Internet bandwidth for each guest client on a Cisco Catalyst 9800 WLC is through a policy map. A policy map allows the creation of policies that can manage traffic within a network. By setting a bandwidth limit within the policy map, the WLC can enforce the required QoS for guest clients. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

Client profiling involves using various properties to identify and classify wireless clients. The HTTP user agent can provide information about the client’s device type and browser, DHCP can reveal details about the client’s network configuration and requests, and the MAC OUI (Organizationally Unique Identifier) can be used to determine the manufacturer of the device. These properties are crucial for profiling because they offer insights into the device’s capabilities and identity. 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 )
