300-430 Exam Dumps - Cisco CCNP Enterprise Questions and Answers

If PEAP authentication is failing and the server is sending an Access-Reject message, one possible action to resolve the issue is to disable the server certificate validation on the client. This means that the client device will not check the authenticity of the RADIUS server’s certificate, which can sometimes resolve connection issues, especially if there is a problem with the certificate chain or trust settings. However, this should be done with caution as it reduces the security of the authentication process. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 To control administrative access to the WLC using Active Directory without concern for RBAC post-authentication, the engineer would configure a RADIUS server (option D) and a TACACS server (option E). These servers can integrate with Active Directory to authenticate users, and once authenticated, the admin user’s access level can be determined without the need for additional role-based access control configurations within the WLC. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, focusing on the integration of WLC with RADIUS and TACACS servers for administrative access control.

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.

AutoQoS simplifies the deployment of QoS by automating the process. On the Cisco Catalyst 9800 Series Wireless Controller, AutoQoS takes into account the characteristics of wireless traffic and helps in implementing a consistent QoS policy across both wired and wireless parts of the network. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

The issue with the Cisco CMX dashboard not showing any data can be resolved by integrating the Wireless LAN Controllers (WLCs) with the CMX system. The CMX solution relies on data from the WLCs to track and detect users’ presence in the office area. Without the WLCs being added to CMX, the system cannot collect the necessary analytics and location data for its operations.

When configuring an Access Control List (ACL) to restrict traffic to the Wireless LAN Controller (WLC) CPU, the direction of the traffic is crucial. Since the ACL is meant to control traffic that is destined for the WLC CPU, it should be set as “Inbound”. This means that any rules applied within this ACL will affect incoming traffic towards the WLC, which is necessary when aiming to restrict certain types of traffic from reaching and potentially overwhelming the controller’s processing capabilities. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

During the Extensible Authentication Protocol (EAP) process, the RADIUS server generates an encrypted session key after the client’s identity is authenticated. This session key is sent to the access point to encrypt data frames between the client and the access point. It ensures that each session has a unique encryption key, enhancing security. References: Look for information on EAP and RADIUS in the CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

 Link-Local Service (LSS) filtering for mDNS (Multicast Domain Name System) is used to control the propagation of mDNS services across the network. To enable LSS for the AppleTV mDNS service only when ORIGIN is set to Wired, the correct action is to set ORIGIN to Wired and enable LSS specifically for the AppleTV service. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The OfficeExtend Access Point (OEAP) split tunnel feature allows the separation of corporate and local traffic. By implementing a split tunnel, remote workers can maintain wireless connectivity to the corporate network while simultaneously accessing local network resources such as printers. This solution ensures that local traffic does not have to traverse the corporate network, which can cause connectivity issues like the ones reported by the users. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

When an engineer enables CPU ACLs on a Cisco device through Security > Access Control Lists > CPU Access Control Lists menu, this change applies immediately to both wireless and wired traffic directed towards the CPU of the device. This includes all management traffic destined for control plane services within the device itself, providing an additional layer of security against potential threats. References: (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)
