 In passive fallback mode for RADIUS, when the primary RADIUS server fails, the controller will start using the secondary RADIUS server. The default timer settings include an inactive timer, which, upon expiration, prompts the controller to attempt to send RADIUS requests back to the primary server. If the primary server is responsive, the controller will resume sending requests to it. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

When configuring multicast for two WLCs in different physical locations, each handling around 500 wireless clients, it is important to assign a unique multicast group address to each WLC. This ensures that multicast traffic is properly segregated and managed within each controller’s network.

The AAA override feature on a WLAN allows for individualized security policies to be applied to users after they are authenticated by the AAA server, which in this case is Cisco ISE (Identity Services Engine). The company policy requires that all users be denied access to any resources until they pass validation. By using AAA override, the network can enforce access control policies based on user credentials and group membership, ensuring that users cannot access network resources until they have been validated by Cisco ISE. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

To create an account for CLI access to an access point for troubleshooting, the WLC must be configured to allow user access with the capability to make changes. The ReadWrite User Access Mode enables an engineer to have full read and write access to the AP’s configuration via the CLI, which is necessary for performing troubleshooting tasks. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

When setting up a new Network Access Device (NAD) on Cisco ISE, it is essential to configure the device’s IP address and the RADIUS shared secret. The device IP address is used to identify the NAD within the network, and the RADIUS shared secret is a password used between the ISE and the NAD to ensure secure communication.

 A successful RF jamming attack primarily disrupts WLAN services by overwhelming the network with noise or unwanted signals, making it impossible for legitimate devices to communicate effectively. While physical damage to AP hardware is not a direct outcome of RF jamming, the persistent interference can lead to hardware malfunction due to overheating or overcompensation for the poor signal environment. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

CMX Facebook Wi-Fi is designed to provide limited access to the network before a user completes authentication. This feature allows HTTP traffic only before authentication while blocking all other traffic, which corresponds with option A. Additionally, it intercepts HTTP traffic to redirect the user to the authentication page, which aligns with option D. The purpose of these restrictions is to ensure that users can be directed to log in via Facebook for Wi-Fi access without compromising network security by allowing unchecked access. 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
