 The configuration for the Rogue Rule named “Rule 1” is set to classify an access point (AP) as malicious if it meets certain conditions. The rule specifies that the AP must have a Minimum RSSI (Received Signal Strength Indicator) of less than or equal to -65 dBm and must have been seen for a Time Duration greater than or equal to 3600 seconds. Among the options provided, both A and C have been seen for more than 3600 seconds, which satisfies the Time Duration condition. However, for the RSSI condition, only option C with an RSSI of -60 dBm meets the criteria of being less than or equal to -65 dBm. Therefore, option C is the correct answer, as it fulfills both conditions set by the Rogue Rule.

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.

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

FastLocate technology enhances location updates’ frequency by utilizing probe requests from clients for real-time location tracking. This method increases the refresh rate of client locations significantly compared to other methods that rely on data packets or RSSI measurements of associated clients only. By implementing a probe-based technique, an engineer can achieve higher location refresh rates as required for location services in an office environment. 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 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

To separate different types of client authentication on a Cisco ISE deployment, policy sets and policy groups can be used. Policy sets allow the creation of policies based on conditions such as device type, while policy groups categorize clients for the application of specific policies. References: Cisco ISE documentation on policy sets and policy groups will have detailed information.

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 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

The Extensible Authentication Protocol (EAP) is an authentication framework frequently used in wireless networks and Point-to-Point connections. During the EAP authentication process, EAP Request and EAP Response packets are exchanged between the supplicant (client device) and the authenticator (network). These packets are used to transport messages for the authentication process. An EAP Request packet is sent by the authenticator requesting identity information from the supplicant, while an EAP Response packet is sent by the supplicant in reply to the request. The other options, such as EAP complete, EAP failure, and EAP reply, are not standard EAP packet types. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

Before deploying an OEAP successfully, the IT administrator must configure the AP mode to FlexConnect and check the box for Office Extend AP ©, and configure the Primary Controller Name and Management IP address in the High Availability tab (E). These settings ensure that the OEAP can establish a connection to the WLC and function correctly in a remote user’s home. 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 )

 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.

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 )

 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.

 The issue described indicates that authentication requests from the wireless network to the RADIUS server are being dropped. This problem is often due to a mismatch in shared-secret keys between the wireless controller and the RADIUS server. The shared secret is a password-like value that must be configured on both sides to ensure secure communication. By configuring both sides with matching shared-secret keys, it ensures that authentication messages are properly encrypted and decrypted by each party, allowing for successful user connection. References: (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

The output observed in Prime Infrastructure suggests that there is at least one strong interferer impacting connectivity at this site. This conclusion is drawn from observing areas marked with intense red coloring indicating high levels of RF interference which could degrade wireless performance significantly if not addressed. 

 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

 For a large company requiring support for 32 VLANs for different departments, the most efficient solution is to configure one single SSID and use Cisco ISE for dynamic VLAN assignment based on user roles. Cisco ISE can classify users into different groups and assign them to the appropriate VLANs. This approach reduces the complexity of managing multiple SSIDs and simplifies the user experience while maintaining a high level of security and network segmentation. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 To improve the speed of client roaming in a wireless network, especially in scenarios where applications are dropping during roams between access points, it is recommended to switch to WPA2 with AES encryption. WPA2AES provides a more robust and efficient encryption method, which can facilitate faster and more secure client handoffs between APs. This change can help mitigate issues with application drops during roaming. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, focusing on client roaming optimization and security protocols for wireless networks.

To segregate all iPads on the guest WLAN to a separate VLAN without using Cisco ISE, the engineer can create a local policy on the WLC (option A). This local policy can be configured to identify iPad devices and assign them to a specific VLAN based on their device profile or other identifying characteristics. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, especially the sections that cover local policies and device profiling on the WLC.

Cisco Prime Infrastructure reporting provides a comprehensive summary of inconsistencies and missed best practices related to WLAN controllers. It aggregates data from all WLCs, Cisco MSE, and itself to generate detailed reports. References: Cisco Prime Infrastructure reporting features documentation.

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.

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)

 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

The issue described indicates a problem with the 802.1X authentication policy on the authenticator, which is typically the wireless controller or access point. Even though the CA certificate is correctly installed on the laptop, if the authenticator’s policy is incorrectly configured or does not match the required settings for the corporate network, the user’s authentication attempts will fail. It is essential to review and correct the 802.1X policy settings on the authenticator to resolve this issue. 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.

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.

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)

For the MSE to communicate with the Cisco Wireless LAN Controller (WLC) over NMSP when installed on a different network, the necessary configuration is to allow TCP/16113 port on the firewall. NMSP uses TCP port 16113 for its communications, and opening this port on the firewall will enable the MSE and WLC to establish a connection and communicate effectively. 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 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)

Mobile Device Management (MDM) integration with Cisco ISE increases security for lost devices by providing functions such as data wipe and jailbreak/root detection. Data wipe allows the remote erasure of sensitive information from lost devices, preventing unauthorized access. Jailbreak/root detection helps identify compromised devices that may bypass standard security measures, ensuring that they do not access network resources.

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.

For rogue containment on an SSID, it’s recommended to use two access points for containment (Option B). Using more than two can lead to unnecessary interference and potential disruption of service for legitimate users, while using just one may not be effective enough in containing the rogue SSID. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

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.

Protocol Independent Multicast (PIM) sparse mode and dense mode are two different multicast routing mechanisms. Sparse mode uses distribution trees and is designed for networks where multicast groups are sparsely distributed across the network, minimizing unnecessary traffic. In contrast, dense mode floods the network with multicast traffic and then prunes back the branches where there are no interested receivers, which can lead to inefficient use of bandwidth. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

To ensure reliable streaming of video content on the wireless network between Cisco FlexConnect APs, Multicast Direct must be enabled.

For central web authentication with Cisco ISE in a Cisco AireOS WLC environment using auto-anchor for the guest network, the foreign WLC must have UDP ports 1812 and 1813 open to ISE for RADIUS authentication and accounting. Additionally, a downloadable preauth ACL on ISE is required to define the permissions for the guest user before authentication, and a local preauth ACL on the WLC is needed to restrict or allow traffic prior to authentication. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, particularly the chapters on WLC configuration for guest access and integration with Cisco ISE for security and access control.

For a network with 3000 APs and 7000 IPS licenses, scaling to a high-end server is appropriate. This will provide the necessary resources and capabilities to support the large number of APs and the extensive licensing requirements for the Intrusion Prevention System.

 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.
