Cisco 300-430 Questions Answers

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.

The feature required on the Cisco Wireless LAN Controller to support dynamic VLAN mapping is AAA override. This feature allows for the assignment of VLANs on a per-user basis as determined by the authentication, authorization, and accounting server. When AAA override is enabled, attributes such as VLAN ID can be dynamically applied to a user’s session after successful authentication and authorization. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

Before deploying an OEAP successfully, the IT administrator must configure the AP mode to FlexConnect and check the box for Office Extend AP ©, and configure the Primary Controller Name and Management IP address in the High Availability tab (E). These settings ensure that the OEAP can establish a connection to the WLC and function correctly in a remote user’s home. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

 The issue described indicates that the Angle of Arrival (AoA) data is not being transmitted between the Cisco Wireless LAN Controller (WLC) and the virtual CMX server. To resolve this, the network administrator must ensure that port 2003 is allowed for AoA packets to flow through between the CMX appliances, which is necessary for Hyperlocation data transmission. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
