Free Practice Questions for Cisco 300-430 Exam

If the Cisco 5520 Series Wireless LAN Controller is no longer manageable via the network after implementing a CPU ACL, permit statements must be added to the top of the ACL in both directions (A). These statements should specify the network from which management is allowed and the virtual interface of the controller to ensure proper management access. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

A Public-Signed SAN (Subject Alternative Name) certificate allows multiple domain names to be protected with a single certificate. This is useful in a distributed environment like a guest portal on Cisco ISE, where there may be multiple nodes with different Common Names (CNs). Using a SAN certificate can prevent CN mismatch errors during SSL/TLS handshakes. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

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.

To change the NTP server on the Cisco CMX server, the administrator should log in to the Cisco CMX CLI and issue the command set ntp server NTP_IP, where NTP_IP is the IP address of the new NTP server. This method is straightforward and does not require manual editing of configuration files or restarting the entire server. References: The process for changing the NTP server on a Cisco CMX server is detailed in the official certification guide, which provides step-by-step instructions for using the CLI.

 mDNS has specific restrictions regarding its configuration. Option C is correct because mDNS is not supported on FlexConnect APs with a locally switched WLAN, which limits its deployment in certain network designs. Option D is also correct; the controller software must be newer than version 7.0.6 to support mDNS features, which means that older controller software versions do not have the necessary capabilities to handle mDNS. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

When configuring access control on a WLC using a TACACS+ server for centralized authentication on network devices, the role value that must be configured under the shell profile on the TACACS+ server for a user with read-only permissions is “MONITOR”. This role restricts the user to monitoring functions without the ability to make changes to the configuration. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

The absence of rogue AP options in the navigation menu under Maps in Cisco Prime Infrastructure (PI) version 3.0 indicates that there is an issue with integrating location services, which are provided by Mobility Services Engine (MSE). Without adding MSE to PI, location-based services such as tracking rogue access points cannot be utilized or displayed within PI’s interface. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

When upgrading a Cisco AireOS WLC from version 7.3 to 8.9, it’s crucial to configure ACLs that allow necessary traffic for Cisco Central Web Authentication (CWA). The correct ACLs to configure are:

B. Permit 0.0.0.0 0.0.0.0 UDP DNS any: This ACL allows DNS queries from any source to any destination, which is essential for resolving domain names during the upgrade process.

E. Permit 0.0.0.0 0.0.0.0 UDP any any: This ACL permits all UDP traffic from any source to any destination, ensuring that services relying on UDP can continue to function during the upgrade.

These ACLs ensure that critical services like DNS resolution are not interrupted during the upgrade process, which could otherwise lead to system instability or failure to access network resources. 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.

For printing services using Bonjour in a WLAN environment where mDNS services are utilized, especially with WLC firmware version 8.x, it’s essential that:

Enable mDNS and IGMP snooping (Option A): Multicast DNS or mDNS needs to be enabled for Bonjour services to function correctly as they rely on this protocol for service discovery within local networks. IGMP snooping improves network efficiency by ensuring multicast traffic is only forwarded to nodes that have explicitly requested it.
