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

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

In Quality of Service (QoS) for networking, Class of Service (COS) and Differentiated Services Code Point (DSCP) are used for traffic classification and prioritization. Voice traffic is generally given high priority due to its sensitivity to delay and requires proper tagging to maintain quality over the network.

The correct mapping for voice traffic, according to best practices, is a COS value of 5 mapped to a DSCP value of 46. This is because DSCP 46 corresponds to Expedited Forwarding (EF), which is typically used for voice traffic prioritization in IP networks.

The exhibit shows the output from a command on a network device that displays the current mappings between COS values and DSCP values. The mapping that needs modification for correct voice traffic tagging can be identified by looking at the standard practice for voice QoS, which uses a COS value of 5 mapped to a DSCP value of 46.

To load balance the data coming through NMSP from the WLCs and spread the load between multiple CMX servers, the configuration cmxctl config feature flags nmsplb.cmx-ap-grouping true should be used. This enables the load balancing feature and helps optimize the data flow for APs in a large network environment. References: The configuration for load balancing in CMX is explained in the certification guide, which outlines the commands and flags necessary to manage data flow efficiently.

When performing a Cisco Hyperlocation accuracy test, the relevant parameters include the X, Y real location and the client MAC address. The X, Y coordinates provide the actual location data needed for the test, while the client MAC address identifies the specific device being located.

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 with users configured for EAP-PEAP not being able to connect to the network, when a Cisco Wireless LAN Controller (WLC) is deployed using local EAP, typically points to a misconfiguration in the local EAP profile on the WLC. EAP-PEAP relies on a server-side certificate to create a secure TLS tunnel for the authentication process. If the local EAP profile is not correctly configured with the proper certificate or other necessary settings, the authentication process will fail, preventing users from connecting. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

The Voice VLAN feature on switches allows the network to distinguish between voice traffic and data traffic from wireless clients connected to IP phones. This is crucial for applying the appropriate QoS to ensure that voice traffic is prioritized over client data traffic. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

The remote LAN (RLAN) feature on the OfficeExtend Access Point (OEAP) is used to extend the wired network through more than one port. This allows the creation of a wired interface on the OEAP that can be associated with a specific VLAN, providing connectivity for wired devices at remote locations. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
