To ensure end-to-end QoS and preserve markings correctly in the VoWLAN setup, the configurations needed on the wired network are trust boundaries and policy maps. Trust boundaries define where the network trusts the QoS markings on packets, and policy maps are used to enforce QoS policies on the network. 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.

 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.

 To connect a Workgroup Bridge (WGB) to a wireless network and authenticate its certificate against a RADIUS server like ISE, the following steps are necessary:

A. Configure the certificate, WLAN, and radio interface on WGB: This is essential because the WGB needs to have the correct certificate to present to the RADIUS server for authentication. Additionally, the WLAN and radio interface must be configured to ensure proper communication with the wireless network.

E. Configure WGB as a network device in ISE: By configuring the WGB as a network device within ISE, it becomes a recognized entity that can be authenticated and authorized accordingly.

F. Configure a policy on ISE to allow devices to connect that validate the certificate: This step ensures that only devices with a validated certificate, such as the WGB, can connect to the network, enhancing security.

The Cisco OfficeExtend Access Point (OEAP) feature is enabled on a Cisco Catalyst 9800 Series Wireless Controller through the Flex Profile. The Flex Profile allows for the configuration of various settings specific to FlexConnect deployments, including OEAP settings, which enable remote workers to connect to the corporate network securely.

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.

 In the context of Cisco Catalyst 9800 Series Wireless Controllers, RADIUS profiling requires the correct AAA (Authentication, Authorization, and Accounting) configuration to collect and forward details about clients to a RADIUS server such as Cisco ISE (Identity Services Engine). The correct command in this scenario is “aaa accounting network acct_method start-stop group rad-group” which enables accounting of network services. This command starts gathering accounting information for all network-related service requests and sends start and stop records to the RADIUS server specified in the ‘rad-group’. This allows the controller to forward information about clients’ activities on the wireless network to Cisco ISE for profiling.

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

 If the administrator is unable to see interferers on the Cisco Prime Infrastructure maps, it could be due to the MSE (Mobility Services Engine) not being added and synchronized with Cisco Prime Infrastructure, which is essential for tracking and locating devices, including interferers. Additionally, if interferer tracking is not enabled on the MSE, it would not track or display the location of interferers on the maps. The other options, such as SNMP failure, reaching the Context Aware Service tracking limit, or inactive NSMP communication, would affect other aspects of network visibility but not specifically the tracking and display of interferers. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
