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

In Cisco Prime Infrastructure, the report that must be created to present a list of all rogue APs with a high severity score to senior management is the “Rogue APs” report. This report provides detailed information about rogue access points detected in the network, including their severity score, which helps in assessing the potential risk they pose to the network security. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

 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.

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

When using FlexConnect Smart AP Image Upgrade without a configured FlexConnect Master AP, the WLC will transfer the image to one indoor AP and one outdoor AP separately. Each AP model needs a different firmware image due to hardware differences. Therefore, there will be two image transfers from the WLC: one for the 2702i APs and another for the 1532i APs.

In a Cisco Wireless LAN Controller (WLC), AP groups are used to manage the distribution of WLANs to different access points (APs). By configuring AP groups, an engineer can specify which WLANs are broadcasted by which APs. This allows for the creation of multiple WLANs across different APs without the need to create new interfaces for each WLAN. AP groups provide the flexibility to control WLAN availability based on location or other criteria, ensuring that only the intended WLANs are available through specific APs.

 To resolve the issue of changing the Cisco Hyperlocation detection threshold, the engineer should shut down all radios on the controller, change the Cisco Hyperlocation detection range, and then enable the radios again. This process ensures that the new threshold settings are applied correctly across the network.

This report is specifically designed to track and list all newly detected rogue APs within the network from a specified time, allowing network administrators to quickly identify unauthorized devices. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

 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 integrate the Mobility Services Engine (MSE) with Cisco Prime Infrastructure for tracking the location of clients and rogues on maps, it is essential to add the MSE to Cisco Prime Infrastructure using the communication credentials specific to Cisco Prime Infrastructure. This ensures that both systems can communicate effectively. Additionally, a valid license for location tracking must be applied to enable the MSE’s location services capabilities. Without this license, the MSE would not be able to provide client and rogue location tracking functionalities. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

 To prevent honeypot attacks most efficiently, the wireless network engineer should set the auto containment level to 4 and select the Using Our SSID containment option (D). This configuration allows the system to automatically contain rogue APs that are spoofing the organization’s SSID, which is a common tactic in honeypot attacks. 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.

An ACL configured for BYOD clients to redirect to a guest portal must allow access to the RADIUS server and Cisco ISE. The RADIUS server is crucial for authentication services, a core component of network access control for BYOD. Cisco ISE integrates with the network infrastructure to provide comprehensive security, including guest access management, thus its accessibility is essential for the redirection process to function correctly. 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

With the implementation of a BYOD policy, the security director should be concerned about malware and lost and stolen devices. Malware can compromise the corporate network if infected devices connect to it. Lost and stolen devices pose a risk of unauthorized access to corporate data and resources, potentially leading to data breaches. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

A Public-Signed SAN (Subject Alternative Name) certificate allows multiple domain names to be protected with a single certificate. This is useful in a distributed environment like a guest portal on Cisco ISE, where there may be multiple nodes with different Common Names (CNs). Using a SAN certificate can prevent CN mismatch errors during SSL/TLS handshakes. 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.

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 )

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

The command cmxha convert backup is used on the backup Cisco CMX server to designate it as the secondary server in a high-availability deployment. This command helps to resolve the issue where both servers are considered primary. References: Cisco CMX high-availability documentation will provide more details on this command.

 The issue described occurs when the fallback feature is disabled on the Cisco AireOS controller. When fallback is disabled, the controller does not attempt to reconnect to the primary TACACS+ server after it becomes available again following a failure. Instead, it continues to use the secondary server until it fails or the controller is rebooted. Enabling fallback would allow the controller to periodically attempt to reconnect to the primary server. 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

The primary change to the network when adding APs for location-based services, such as VolMLAN, would be the AP footprint. This refers to the physical coverage area of the access points. Increasing the AP footprint enhances the ability to perform location-based services by improving the accuracy of triangulation and location tracking of devices. This is because a denser AP footprint allows for more precise determination of a device’s location within the network. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, specifically the sections discussing location-based services and AP deployment strategies for optimal coverage and location tracking.

 FlexConnect is a wireless solution for branch office and remote office deployments. It allows APs to switch client data traffic locally and perform client authentication locally when they are disconnected from the WLC. For WLAN A to work in FlexConnect mode and WLAN B to work in local mode, the APs need to be part of a FlexConnect group with proper WLAN-VLAN mappings. This ensures that the correct VLAN is used for each WLAN, which is essential when the APs are operating in FlexConnect mode. 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.
