 The correct configuration for limiting Internet bandwidth for each guest client on a Cisco Catalyst 9800 WLC is through a policy map. A policy map allows the creation of policies that can manage traffic within a network. By setting a bandwidth limit within the policy map, the WLC can enforce the required QoS for guest clients. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

 IGMP snooping is a feature that allows a network switch to listen to the Internet Group Management Protocol (IGMP) network traffic. This feature enables the switch to identify the multicast streams to which hosts are interested and to forward multicast traffic intelligently. By enabling IGMP snooping on the Wireless LAN Controller (WLC), it ensures that multicast streams are only forwarded to the access points (APs) where clients are subscribed to them. Setting the AP multicast mode to a specific multicast address, such as 238.255.255.255, allows the WLC to send multicast traffic to APs using this address, which helps in efficient distribution of the multicast stream.

In Cisco Prime Infrastructure, the maximum number of APs that can be used to contain an identified rogue access point in the WLC is four (4). This containment process involves using nearby APs to disrupt the rogue AP’s signals, thereby preventing it from effectively communicating with client devices. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, which includes information on rogue AP detection and containment strategies within the WLC and Cisco Prime Infrastructure.

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).

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 correct command set for configuring a Cisco Catalyst 9800 Series Wireless Controller so that the client traffic enters the network at the AP switch port is Option C:

config terminal

wireless profile policy [policy name]

no central switching

end

This configuration disables central switching, which means that client traffic will be locally switched at the access point level rather than being sent through the controller. This is useful in scenarios where local switching is preferred due to reasons such as reducing latency or conserving bandwidth on WAN links. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

 When a network engineer receives an alert about a rogue AP and determines it is a security threat inside the campus, the fastest way to disable it is by updating its status in Cisco Prime Infrastructure to ‘contained’. This action instructs the system to prevent the rogue device from communicating with other devices on the network, effectively isolating it without having to physically locate or manually disable it. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

When configuring access control on a WLC using a TACACS+ server for centralized authentication on network devices, the role value that must be configured under the shell profile on the TACACS+ server for a user with read-only permissions is “MONITOR”. This role restricts the user to monitoring functions without the ability to make changes to the configuration. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

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 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.

The Cisco Aironet 600 Series OfficeExtend APs support various Layer 2 security options, including WPA+WPA2 and 802.1X. WPA and WPA2 provide secure encryption for wireless data, while 802.1X offers a robust authentication framework. These security options ensure that the wireless network is protected against unauthorized access and data breaches, which is crucial for remote workers connecting to the corporate network. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 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.

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

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
