Cisco Updated 300-430 Exam Questions and Answers by dax

 When a Cisco Wireless LAN Controller (WLC) is added to Cisco ISE as a network device for authentication purposes, it is crucial to verify the shared secret configured within the network device settings. The shared secret is used to secure communication between the WLC and ISE, ensuring that the authentication messages are encrypted and authenticated. If the shared secret does not match on both the WLC and ISE, the authentication will fail. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

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 )

The Platinum QoS marking is typically used for the highest-priority traffic, such as voice and video. Given the requirement for a high average bitrate for the video application, Platinum would be the appropriate QoS marking to ensure the necessary bandwidth and priority on the WLAN. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

 In a BYOD (Bring Your Own Device) deployment strategy that prefers a single SSID model, an Identity Services Engine (ISE) is required. Cisco’s ISE is a security policy management platform that automates and enforces context-aware security access to network resources. It allows for the creation of policies that control access to the network based on user identity, device type, device health, and posture compliance, which is essential for a BYOD environment. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
