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

Split tunneling on a Cisco Aironet 600 Series OfficeExtend AP allows for traffic to be divided between two different networks. In this case, it enables the user to access the corporate network for work-related tasks while simultaneously allowing them to print to a printer on their home network. This is achieved by routing the traffic meant for the corporate network to the WLC, while local traffic such as the connection to a home printer is kept on the local network. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

For high availability configuration in Cisco CMX servers to work correctly, both primary and secondary servers must be identical in terms of installation type (physical or virtual) and size (resources allocated like CPU, RAM). If there is a mismatch in these aspects, it can lead to failure in setting up high availability as they need to synchronize data between them seamlessly. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

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.

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

 Cisco DNA Center is likely ignoring the interference detected by the AP because it includes only Cisco CleanAir interferers in the AP health score (option C), and the interference is less than or equal to 30% on the 5 GHz radio (option D). Cisco DNA Center’s AP health score algorithm may not consider interference that falls below a certain threshold or interference that is not identified as a CleanAir event. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, particularly the chapters on Cisco DNA Center and CleanAir technology.

The configuration that must be applied in the RADIUS Authentication Settings section from the ISE Network Device page when clients are able to authenticate successfully but the ISE policies designed to place them on different interfaces are not working is to change the CoA Port. The CoA (Change of Authorization) port is used by ISE to send messages to the network device to apply different policies post-authentication. If the CoA port is not correctly configured, the network device will not receive or act upon these messages, resulting in clients not being placed on the correct interfaces as per ISE policies. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

For a network using EIGRP and BGP within a single domain from a single source, Protocol Independent Multicast Sparse Mode (PIM-SM) is the most suitable multicast routing to be implemented. PIM-SM is efficient for networks with a large number of networks and few receivers, which seems to be the case for an all-company video meeting.

 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)

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
