Cisco Updated 300-430 Exam Questions and Answers by minha

The default IEEE 802.1x AP authentication configuration on a Cisco Catalyst 9800 Series Wireless Controller is EAP-FAST with CAPWAP DTLS (Option D). This method uses EAP-FAST for authentication within a secure tunnel established by Datagram Transport Layer Security (DTLS) over CAPWAP, which provides both security for authentication credentials and encryption for wireless management frames. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

 FlexConnect is a wireless solution for branch office and remote office deployments. It allows APs to switch client data traffic locally and perform client authentication locally when they are disconnected from the WLC. For WLAN A to work in FlexConnect mode and WLAN B to work in local mode, the APs need to be part of a FlexConnect group with proper WLAN-VLAN mappings. This ensures that the correct VLAN is used for each WLAN, which is essential when the APs are operating in FlexConnect mode. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

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.
