The feature required on the Cisco Wireless LAN Controller to support dynamic VLAN mapping is AAA override. This feature allows for the assignment of VLANs on a per-user basis as determined by the authentication, authorization, and accounting server. When AAA override is enabled, attributes such as VLAN ID can be dynamically applied to a user’s session after successful authentication and authorization. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

VLAN-based central switching is the feature that meets the requirements stated. With this feature, when a subnet assigned to a client is available at the remote site, the traffic is offloaded locally. If the subnet is not available, the traffic is tunneled back to the Wireless LAN Controller (WLC). This setup allows for dynamic assignment of clients to specific IP subnets using Cisco Identity-Based Networking Services with ISE. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 To control administrative access to the WLC using Active Directory without concern for RBAC post-authentication, the engineer would configure a RADIUS server (option D) and a TACACS server (option E). These servers can integrate with Active Directory to authenticate users, and once authenticated, the admin user’s access level can be determined without the need for additional role-based access control configurations within the WLC. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, focusing on the integration of WLC with RADIUS and TACACS servers for administrative access control.

The feature that must be enabled to ignore non-802.11 interference is “Avoid Persistent Non-WiFi Interference.” This setting allows the Radio Resource Management (RRM) to not react to non-802.11 noise and interference, which can be crucial in environments where such interference is common but does not significantly impact wireless performance. By enabling this feature, RRM will not change the channel in response to non-IEEE 802.11 interferers, thus maintaining a stable channel plan. 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.

 Application Visibility and Control (AVC) profiles in AireOS controllers allow the identification and management of bandwidth consumption by different applications. By using AVC, administrators can set policies to prioritize or restrict bandwidth for specific applications, thus ensuring that critical services like voice and video are not adversely affected by bandwidth-heavy programs. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

In this scenario where branch wireless users can still associate locally but cannot access head office services due to WAN downtime indicates that Cisco FlexConnect is likely in use. The correct elements are: A - authentication-local/switch-local: This means that client authentication and data switching are happening locally at the branch. E - standalone mode: With WAN down, FlexConnect APs operate in standalone mode allowing clients to associate even without connectivity back to WLC. F - WEB authentication: This could be used as an authentication method regardless of WAN state since it’s processed locally at AP level. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

Trusting DSCP is essential for maintaining the QoS markings across the wired and wireless network in a FlexConnect deployment. By trusting DSCP, the WLC and APs will preserve the QoS markings set by applications and devices, ensuring consistent QoS treatment throughout the network. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

 Cisco DNA Center is likely ignoring the interference detected by the AP because it includes only Cisco CleanAir interferers in the AP health score (option C), and the interference is less than or equal to 30% on the 5 GHz radio (option D). Cisco DNA Center’s AP health score algorithm may not consider interference that falls below a certain threshold or interference that is not identified as a CleanAir event. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, particularly the chapters on Cisco DNA Center and CleanAir technology.
