To ensure end-to-end QoS and preserve markings correctly in the VoWLAN setup, the configurations needed on the wired network are trust boundaries and policy maps. Trust boundaries define where the network trusts the QoS markings on packets, and policy maps are used to enforce QoS policies on the network. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

If PEAP authentication is failing and the server is sending an Access-Reject message, one possible action to resolve the issue is to disable the server certificate validation on the client. This means that the client device will not check the authenticity of the RADIUS server’s certificate, which can sometimes resolve connection issues, especially if there is a problem with the certificate chain or trust settings. However, this should be done with caution as it reduces the security of the authentication process. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

To assess different client types connected to a Cisco Catalyst 9800 Series Wireless Controller without using external servers, the device classification feature (D) can be used. This feature allows the controller to classify devices based on their MAC addresses and other characteristics. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The Out-of-Sync alarms in Cisco Prime Infrastructure typically indicate that there is a discrepancy between the configuration of the APs as known by Prime Infrastructure and their actual configuration. To resolve this issue, the engineer can either manually synchronize the APs from Cisco Prime Infrastructure (A) or enable automatic synchronization on Cisco Prime Infrastructure © to ensure that the AP configurations are updated automatically. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 In a distributed deployment of Cisco ISE, profiling services are configured on Policy Services Nodes (PSNs). These nodes handle all context-based access control, including profiling services.

To load balance the data coming through NMSP from the WLCs and spread the load between multiple CMX servers, the configuration cmxctl config feature flags nmsplb.cmx-ap-grouping true should be used. This enables the load balancing feature and helps optimize the data flow for APs in a large network environment. References: The configuration for load balancing in CMX is explained in the certification guide, which outlines the commands and flags necessary to manage data flow efficiently.

The correct URL to be used in the configuration as the external redirection URL for guests to view the company’s Facebook page before accessing the network is http:// :8083/fbwifi/forward (B). This URL is associated with the Cisco MSE’s Facebook Wi-Fi feature, which facilitates the redirection process. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

To ensure that only admins have access to network device management while allowing guest users to reach the web portal, access to Cisco ISE must be permitted on the pre-authentication ACL. This configuration allows guests to interact with the portal without granting them broader network access.

To route wireless traffic from the branch through the firewall at corporate headquarters, the correct Cisco FlexConnect configuration is central authentication and central switching. This setup ensures that both user authentication and data traffic are handled centrally at the corporate headquarters, allowing the firewall to inspect and route the traffic accordingly. Local RADIUS servers in each branch can still be used for redundancy or other purposes, but the central control of traffic is maintained. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

The issue is likely caused by the CPU ACL on the controller, which is blocking HTTP/HTTPS traffic from the guest clients. When a WLAN with Web Authentication is used, the wireless client’s browser is redirected to a web page for authentication. If the CPU ACL is configured to only allow controller web management traffic from the IT subnet, it may inadvertently block the necessary HTTP/HTTPS traffic for the Web Authentication process, leading to a timeout on the wireless client browser. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, specifically the sections discussing CPU ACLs and their impact on network traffic.
