Cisco 300-430 - Implementing Cisco Enterprise Wireless Networks (300-430 ENWLSI)

Removing unnecessary controllers from the mobility group (B) would create less load on the controllers while maintaining the same mobility messages. This is because each controller in a mobility group shares its client database with other controllers, which can lead to increased overhead. By minimizing the number of controllers in the group, the load is reduced. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

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

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 )

When designing a high availability wireless network, the focus should be on cell overlap. Adequate cell overlap ensures that if one access point fails, another can provide coverage without service interruption, thus maintaining network resilience and availability. References: 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

When planning an image upgrade for a large number of Access Points (APs) across remote sites with limited WAN bandwidth, it’s crucial to minimize WAN utilization. The best approach in this scenario is:

Predownload the new code to the APs (Option A): This method involves sending the new firmware image to all APs before actually rebooting them with the new image. It allows APs to download firmware when network usage is low, thus minimizing impact during peak hours.

 If all APs are receiving multicast traffic instead of only those that need it, it indicates that Multicast Internet Group Management Protocol (IGMP) snooping is not enabled. IGMP snooping is a feature that allows a network switch to listen to IGMP network traffic and ensure that multicast packets are only sent to the ports associated with interested receivers, thus preventing unnecessary traffic on the network. 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. This feature allows for efficient multicast traffic delivery by converting multicast streams into unicast streams for each client, which guarantees delivery even in environments where reliable multicast is not feasible. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The issue is likely caused by the CPU ACL on the controller, which is blocking HTTP/HTTPS traffic from the guest clients. When a WLAN with Web Authentication is used, the wireless client’s browser is redirected to a web page for authentication. If the CPU ACL is configured to only allow controller web management traffic from the IT subnet, it may inadvertently block the necessary HTTP/HTTPS traffic for the Web Authentication process, leading to a timeout on the wireless client browser. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, specifically the sections discussing CPU ACLs and their impact on network traffic.
