Free Practice Questions for Cisco 300-430 Exam

To ensure end-to-end QoS and preserve markings correctly in the VoWLAN setup, the configurations needed on the wired network are trust boundaries and policy maps. Trust boundaries define where the network trusts the QoS markings on packets, and policy maps are used to enforce QoS policies on the network. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

To take full advantage of the WLAN configuration, VoWLAN phones must support 802.11e, which is a standard for wireless QoS, and Wi-Fi Multimedia (WMM), which is a subset of 802.11e that provides prioritized media delivery. These standards ensure that voice traffic is prioritized appropriately in the wireless network. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

 For a large company requiring support for 32 VLANs for different departments, the most efficient solution is to configure one single SSID and use Cisco ISE for dynamic VLAN assignment based on user roles. Cisco ISE can classify users into different groups and assign them to the appropriate VLANs. This approach reduces the complexity of managing multiple SSIDs and simplifies the user experience while maintaining a high level of security and network segmentation. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

To assess different client types connected to a Cisco Catalyst 9800 Series Wireless Controller without using external servers, the device classification feature (D) can be used. This feature allows the controller to classify devices based on their MAC addresses and other characteristics. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

In a Cisco wireless LAN controller, setting a specific data rate to ‘Mandatory’ means that all wireless clients must be able to communicate at this rate. To ensure that multicast uses the 54Mbps rates, one must set the 54Mbps data rate to ‘Mandatory’. This configuration will make it so that all multicast traffic is transmitted at this minimum set data rate, thus meeting the requirement specified by the engineer.

 EAP-TLS (Extensible Authentication Protocol-Transport Layer Security) is an EAP method that an Access Point (AP) can use to authenticate to the wired network. EAP-TLS is considered one of the most secure EAP methods because it uses mutual authentication, where both the client and the server authenticate each other using certificates.

 To prevent honeypot attacks most efficiently, the wireless network engineer should set the auto containment level to 4 and select the Using Our SSID containment option (D). This configuration allows the system to automatically contain rogue APs that are spoofing the organization’s SSID, which is a common tactic in honeypot attacks. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

On the Global Configuration page of a Wireless LAN Controller (WLC), for an Access Point (AP) to use IEEE 802.1X for authenticating to the wired infrastructure, it is necessary to configure a RADIUS shared secret. This secret will be used by the AP as part of its credentials when communicating with a RADIUS server during the authentication process. References: (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

 For a BYOD setup using a dual SSID approach, the first SSID is typically used for device registration and the second for network access. Setting the NAC State to Radius NAC enables the network access control (NAC) to use RADIUS for authentication, authorization, and accounting. Allowing AAA Override enables the RADIUS server to dynamically change the VLAN and ACLs assigned to the endpoint, which is crucial for BYOD where devices need to be placed into the correct VLAN based on user role and device type. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, particularly the chapters on BYOD and advanced WLAN configuration.
