Cisco 300-430 Implementing Cisco Enterprise Wireless Networks (300-430 ENWLSI) Exam Practice Test

 In a Cisco WLAN deployment where it is required that all APs from branch1 remain operational even if the control plane CAPWAP tunnel is down, the operational mode that must be configured on the APs is standalone (option B). In standalone mode, the APs can continue to function and provide network access to clients even without a connection to the WLC, which is essential during a WAN failure to headquarters. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, with a focus on AP operational modes and their behavior during network disruptions.

For optimal voice over WLAN performance with a Cisco 8821 wireless phone, the Cisco recommended configuration is to set the switch port to access mode and trust the DSCP markings. This ensures that voice traffic is appropriately prioritized in the network, providing better quality of service for voice communications. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 To ensure the 1810 OEAP can join the controller from remote teleworker locations, the firewall must allow specific UDP ports that are used for AP communication with the controller. UDP ports 5246 and 5247 are used for Control and Provisioning of Wireless Access Points (CAPWAP) control and data messages, while UDP ports 12222 and 12223 are used for OfficeExtend APs’ data traffic. Blocking these ports would prevent the APs from joining the controller, hence they must be allowed on the firewall.

The Voice VLAN feature on switches allows the network to distinguish between voice traffic and data traffic from wireless clients connected to IP phones. This is crucial for applying the appropriate QoS to ensure that voice traffic is prioritized over client data traffic. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

The default NMSP echo interval between Cisco MSE and a Wireless LAN Controller is 15 seconds. This interval determines how frequently the MSE sends echo messages to the WLC to maintain the NMSP connection and ensure that the link is active and operational. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

 To ensure the 1810 OEAP can join the controller from remote teleworker locations, the firewall must allow specific UDP ports that are used for AP communication with the controller. UDP ports 5246 and 5247 are used for Control and Provisioning of Wireless Access Points (CAPWAP) control and data messages, while UDP ports 12222 and 12223 are used for OfficeExtend APs’ data traffic. Blocking these ports would prevent the APs from joining the controller, hence they must be allowed on the firewall.

 For a BYOD setup using a dual SSID approach, the first SSID is typically used for device registration and the second for network access. Setting the NAC State to Radius NAC enables the network access control (NAC) to use RADIUS for authentication, authorization, and accounting. Allowing AAA Override enables the RADIUS server to dynamically change the VLAN and ACLs assigned to the endpoint, which is crucial for BYOD where devices need to be placed into the correct VLAN based on user role and device type. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, particularly the chapters on BYOD and advanced WLAN configuration.

The issue with users configured for EAP-PEAP not being able to connect to the network, when a Cisco Wireless LAN Controller (WLC) is deployed using local EAP, typically points to a misconfiguration in the local EAP profile on the WLC. EAP-PEAP relies on a server-side certificate to create a secure TLS tunnel for the authentication process. If the local EAP profile is not correctly configured with the proper certificate or other necessary settings, the authentication process will fail, preventing users from connecting. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

The absence of rogue AP options in the navigation menu under Maps in Cisco Prime Infrastructure (PI) version 3.0 indicates that there is an issue with integrating location services, which are provided by Mobility Services Engine (MSE). Without adding MSE to PI, location-based services such as tracking rogue access points cannot be utilized or displayed within PI’s interface. 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

 Bluetooth Low Energy (BLE) is renowned for its ability to provide precise location services, especially in the context of indoor positioning systems. BLE beacons can be strategically placed throughout a facility, and when used in conjunction with a mobile application, they can deliver the high level of location accuracy required for various use cases, including navigation, asset tracking, and contextual marketing.

To collect user demographic information in exchange for guest WLAN access and to have a customized portal per location, the marketing department should tie the Facebook social connector into Cisco CMX. Facebook is widely used for social login features and provides access to demographic data when users consent, making it the ideal choice for this requirement. References: The use of social connectors for demographic data collection is discussed in the context of advanced location services in the official certification guide.

When a wireless controller is configured to authenticate clients against Microsoft Active Directory using PEAP (Protected Extensible Authentication Protocol), it uses RADIUS (Remote Authentication Dial-In User Service) as the protocol to communicate with the authentication server. RADIUS is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.

The remote LAN (RLAN) feature on the OfficeExtend Access Point (OEAP) is used to extend the wired network through more than one port. This allows the creation of a wired interface on the OEAP that can be associated with a specific VLAN, providing connectivity for wired devices at remote locations. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The OfficeExtend Access Point (OEAP) split tunnel feature allows the separation of corporate and local traffic. By implementing a split tunnel, remote workers can maintain wireless connectivity to the corporate network while simultaneously accessing local network resources such as printers. This solution ensures that local traffic does not have to traverse the corporate network, which can cause connectivity issues like the ones reported by the users. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

During the Extensible Authentication Protocol (EAP) process, the RADIUS server generates an encrypted session key after the client’s identity is authenticated. This session key is sent to the access point to encrypt data frames between the client and the access point. It ensures that each session has a unique encryption key, enhancing security. References: Look for information on EAP and RADIUS in the CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

TACACS+ (Terminal Access Controller Access-Control System Plus) is recommended for managing device access as it provides a more granular level of control over user authentication and authorization than RADIUS. It allows for different levels of access based on user identity by interfacing with external repositories such as Active Directory or LDAP. This protocol helps in distinguishing between different users and assigning appropriate access rights based on their roles within an organization. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 For a startup company without LDAP, using the internal database of the RADIUS server is a viable solution to authenticate wireless users. This approach allows the company to maintain a directory of users within the RADIUS server itself, providing similar security and user experience as LDAP would. Users can be authenticated against this internal database, ensuring secure access to the wireless network. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

When an engineer enables CPU ACLs on a Cisco device through Security > Access Control Lists > CPU Access Control Lists menu, this change applies immediately to both wireless and wired traffic directed towards the CPU of the device. This includes all management traffic destined for control plane services within the device itself, providing an additional layer of security against potential threats. 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)

The Cisco Hyperlocation feature requires enabling on both the wireless LAN controller and Cisco CMX to function correctly. This allows for precise location tracking by integrating data from both components. Additionally, if the Cisco CMX server is a virtual machine (VM), it is recommended to use a high-end VM to handle the processing demands of Cisco Hyperlocation deployments, ensuring optimal performance and accuracy.

For RADIUS to restrict administrative control effectively, the engineer needs to define a Network Access Server (NAS) entry that corresponds to the WLC’s management IP address and the AP subnet. The correct entry would be the NAS IP of the virtual interface (typically used for RADIUS communications) and the specific network range of the AP subnet, which is 192.168.2.0 with a subnet mask of 255.255.255.0. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

To segregate iOS-connected devices onto a guest SSID on VLAN 101 and the rest of the clients on VLAN 102, specific configurations are needed on the Cisco Catalyst 9800 Wireless LAN Controller (WLC). The correct configurations required are:

• Add local profiling policy under global security policy settings (Option B): This allows the WLC to profile devices based on their operating system. By identifying iOS devices, a local profiling policy can then direct these devices to the appropriate VLAN.
• Enable device classification on global wireless settings (Option E): Device classification is necessary for the WLC to differentiate between device types. Once enabled, it can apply different policies based on whether a device is recognized as an iOS device or not.

References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

To enable VLAN tagging for wireless Identity-Based Networking on a WLAN, an engineer must enable AAA override, which allows for dynamic VLAN assignment. Additionally, the RADIUS server attributes need to be updated to include tunnel type 64, medium type 65, and tunnel private group type 81, which are necessary for VLAN tagging information. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

To segregate iOS devices to the guest SSID on VLAN 101 and distribute the rest of the clients on VLAN 102, creating a service template and enabling device classification are required. The service template specifies the VLAN assignment, while device classification identifies the type of device connecting to the network. References: Cisco Catalyst 9800-80 WLC documentation on local policies and device classification.

During the Extensible Authentication Protocol (EAP) process, the RADIUS server generates an encrypted session key after the client’s identity is authenticated. This session key is sent to the access point to encrypt data frames between the client and the access point. It ensures that each session has a unique encryption key, enhancing security. References: Look for information on EAP and RADIUS in the CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

 In Cisco CMX, to view active RFID tags, the engineer needs to enable the tracking of these tags within the system settings. This is typically done by selecting an option that allows for RFID tag tracking, which makes them visible on location-based services like the Detect and Locate window of Cisco CMX. By enabling this feature, the system starts to interpret signals from RFID tags and displays their location accordingly. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The issue with the Cisco CMX dashboard not showing any data can be resolved by integrating the Wireless LAN Controllers (WLCs) with the CMX system. The CMX solution relies on data from the WLCs to track and detect users’ presence in the office area. Without the WLCs being added to CMX, the system cannot collect the necessary analytics and location data for its operations.

The correct command to shut down the 2.4 GHz radio on a specific AP on a Cisco 3850 switch is ap name Floor1_AP1 dot11 24ghz shutdown. This command specifies the AP by name (Floor1_AP1), the radio frequency band (dot11 24ghz), and the action to be taken (shutdown). The other commands listed either reference the wrong frequency band, use incorrect syntax, or are not valid Cisco IOS commands for managing AP radios. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 For a wireless network supporting voice and video applications for Apple devices, especially with Fastlane implementation, the QoS profile to configure on the user WLAN for iPhones updated to version 14.5.432302546 is Platinum. This profile provides the highest level of QoS, ensuring priority for voice and video traffic. References:= (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

Allowing access to the Local Area Network (LAN) without implementing a Mobile Device Management (MDM) solution poses a significant security risk to a Bring Your Own Device (BYOD) policy. Without MDM, the organization lacks control over the personal devices that connect to its network, which could lead to unauthorized access to sensitive data, potential data breaches, and the inability to enforce security policies.

To address concerns about detecting spurious threats from channels not used by the wireless infrastructure, deploying APs in monitor mode (B) and local mode with WIPS submode (D) would be beneficial. Monitor mode allows APs to listen to the wireless spectrum and identify potential threats, while WIPS (Wireless Intrusion Prevention System) submode enhances the ability to detect and mitigate wireless threats. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

Application Visibility and Control (AVC) profiles must be implemented to remark the QoS value for WebEx traffic. AVC profiles allow the network to identify different applications and provide the appropriate QoS treatment, ensuring high-quality meetings. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

Fastlane is a feature developed by Apple and Cisco that provides a higher-quality user experience for critical business applications. To implement Fastlane, the WLAN must use the Platinum QoS profile, which is designed to prioritize business-critical traffic and applications. Since the IT department has updated the iPads to a specific version, it is important to ensure that the QoS settings align with the requirements of Fastlane to maintain application performance and security.

 When configuring an autonomous Access Point (AP) for 802.1x authentication using an external authentication server like RADIUS, it’s essential that AP knows where to send authentication requests and has a secure method of communicating with it. The RADIUS server’s IP address must be configured on AP so it knows where to forward user credentials for verification. Additionally, a shared secret must be set up between AP and RADIUS server as part of their secure communication protocol; without this shared secret, they cannot trust each other’s communications. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 To provide guests access using social media authentication, the engineer must configure the “Social Connect” service. This service allows guests to use their Facebook credentials, among other social media platforms, to authenticate and gain network access. It simplifies the guest access process by leveraging existing social media accounts for authentication. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

The bronze QoS level is typically recommended for guest services in a wireless network environment. This level prioritizes basic internet access, which is suitable for guest services that do not require high bandwidth or low latency. It ensures that more critical services are not impacted by guest traffic, which is often less sensitive to performance fluctuations. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The issue with users configured for EAP-PEAP not being able to connect to the network, when a Cisco Wireless LAN Controller (WLC) is deployed using local EAP, typically points to a misconfiguration in the local EAP profile on the WLC. EAP-PEAP relies on a server-side certificate to create a secure TLS tunnel for the authentication process. If the local EAP profile is not correctly configured with the proper certificate or other necessary settings, the authentication process will fail, preventing users from connecting. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

In Quality of Service (QoS) for networking, Class of Service (COS) and Differentiated Services Code Point (DSCP) are used for traffic classification and prioritization. Voice traffic is generally given high priority due to its sensitivity to delay and requires proper tagging to maintain quality over the network.

The correct mapping for voice traffic, according to best practices, is a COS value of 5 mapped to a DSCP value of 46. This is because DSCP 46 corresponds to Expedited Forwarding (EF), which is typically used for voice traffic prioritization in IP networks.

The exhibit shows the output from a command on a network device that displays the current mappings between COS values and DSCP values. The mapping that needs modification for correct voice traffic tagging can be identified by looking at the standard practice for voice QoS, which uses a COS value of 5 mapped to a DSCP value of 46.

The Voice VLAN feature on switches allows the network to distinguish between voice traffic and data traffic from wireless clients connected to IP phones. This is crucial for applying the appropriate QoS to ensure that voice traffic is prioritized over client data traffic. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

When implementing Cisco Identity-Based Networking on a Cisco AireOS controller with two ACLs where one is applied directly on the WLC interface and another referenced by ISE for a specific group policy, the resulting ACL for a user in that group would be a combination of both ACLs. The BASE_ACL applied on the corporate_clients interface acts as the default ACL for all corporate clients, while HR_ACL is specific for Human Resources users. When a Human Resources user connects, HR_ACL takes precedence but does not replace BASE_ACL; instead, it appends its rules to those of BASE_ACL resulting in an aggregated set of rules from both ACLs. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

When a client is authenticated but cannot pass traffic in the RUN state, it indicates that an ACL may be blocking the traffic post-authentication. Disabling or modifying this ACL to allow traffic can resolve the connectivity issue, ensuring that the client’s traffic flows correctly after authentication with Cisco ISE.

 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

 EAP-TLS (Extensible Authentication Protocol-Transport Layer Security) is an EAP method that an Access Point (AP) can use to authenticate to the wired network. EAP-TLS is considered one of the most secure EAP methods because it uses mutual authentication, where both the client and the server authenticate each other using certificates.

When setting up identity-based networking with ISE and configuring AAA override on the WLAN, the attributes that can be used to change the client behavior from the default settings include the DNS server and DSCP value. The DNS server attribute allows for the specification of a DNS server per client, which can be essential for directing traffic through specific network paths or applying policies based on domain name resolutions. The DSCP value attribute is used to mark the packets with a specific Quality of Service (QoS) level, which can prioritize or deprioritize traffic as needed. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

The maximum time range that can be viewed on the Cisco DNA Center issues and alarms page is 24 hours.

The true statement about the VideoStream/Multicast Direct feature is that each VideoStream client acknowledges receiving a video IP multicast stream. This feature enhances the reliability of IP multicast traffic over WLAN by using client acknowledgments to ensure delivery.

References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

When configuring an Access Control List (ACL) to restrict traffic to the Wireless LAN Controller (WLC) CPU, the direction of the traffic is crucial. Since the ACL is meant to control traffic that is destined for the WLC CPU, it should be set as “Inbound”. This means that any rules applied within this ACL will affect incoming traffic towards the WLC, which is necessary when aiming to restrict certain types of traffic from reaching and potentially overwhelming the controller’s processing capabilities. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The Media Stream feature on a Cisco WLC allows for the prioritization of streaming media. To guarantee at least 2 Mbps stream per user, the ‘coarse’ Resource Reservation Control (RRC) template should be used, as it provides the necessary bandwidth allocation for each user’s media stream. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

In a Cisco wireless LAN controller, setting a specific data rate to ‘Mandatory’ means that all wireless clients must be able to communicate at this rate. To ensure that multicast uses the 54Mbps rates, one must set the 54Mbps data rate to ‘Mandatory’. This configuration will make it so that all multicast traffic is transmitted at this minimum set data rate, thus meeting the requirement specified by the engineer.

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)

 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 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 performing a Cisco Hyperlocation accuracy test, the relevant parameters include the X, Y real location and the client MAC address. The X, Y coordinates provide the actual location data needed for the test, while the client MAC address identifies the specific device being located.

For guests to reach a Web Authentication Redirect page while blocking web management traffic to the controller, guest client HTTPS traffic must be allowed to a specific IP address that does not interfere with management access. The virtual interface IP on a Cisco Wireless LAN Controller serves as a DHCP relay and is used for web authentication processes. Therefore, allowing HTTPS traffic to this IP enables guests to reach the redirect page without granting them access to manage the controller. 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)

When an IT department needs to locate a stolen laptop using its MAC address, enabling Location History for Clients on the Mobility Services Engine (MSE) is crucial as it allows for historical tracking of client devices’ locations. Furthermore, Client location tracking must also be enabled on the MSE; this feature actively tracks and updates the current position of all client devices in real-time. Both settings are necessary to provide a comprehensive view of where the laptop has been over time and its current location within the wireless network’s coverage area. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

 The benefit of using dual SSIDs with a captive portal on the onboard SSID compared to a single SSID solution is the ability to restrict allowed device types. With a dual SSID setup, one SSID can be used for onboarding new devices with a captive portal that can enforce policies and check the device type before allowing access to the main SSID. This helps in maintaining a secure and compliant network environment. 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.

 When configuring Cisco OfficeExtend Access Points (OEAPs), enabling NAT IP only for office-extend is necessary if the APs are behind a NAT device and need to communicate with the Wireless LAN Controller (WLC) using the internal IP management address. The command config flexconnect office-extend nat-ip-only enable allows the APs to discover and associate with the WLC when the management interface is configured with a NAT address.

Local EAP (Extensible Authentication Protocol) allows wireless LAN controllers to directly authenticate clients using an internal database, which can be useful when external RADIUS servers are unreachable. By enabling local EAP, client devices can still connect to wireless networks even if communication with RADIUS servers fails, ensuring continuous network access for users. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
