300-430 Cisco Implementing Cisco Enterprise Wireless Networks (300-430 ENWLSI) Free Practice Exam Questions (2025 Updated)

The Out-of-Sync alarms in Cisco Prime Infrastructure typically indicate that there is a discrepancy between the configuration of the APs as known by Prime Infrastructure and their actual configuration. To resolve this issue, the engineer can either manually synchronize the APs from Cisco Prime Infrastructure (A) or enable automatic synchronization on Cisco Prime Infrastructure © to ensure that the AP configurations are updated automatically. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

When a wireless controller is configured to authenticate clients against Microsoft Active Directory using PEAP (Protected Extensible Authentication Protocol), it uses RADIUS (Remote Authentication Dial-In User Service) as the protocol to communicate with the authentication server. RADIUS is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.

 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.

In a FlexConnect group with local switching but central DHCP, clients can use features like multicast and static IP without any issues. However, fast roaming, which allows clients to move seamlessly between access points with minimal delay, requires the access points to handle client information locally. If the configuration is changed to allow local DHCP, then the access points can cache client credentials, enabling fast roaming.

The true statement about the VideoStream/Multicast Direct feature is that each VideoStream client acknowledges receiving a video IP multicast stream. This feature enhances the reliability of IP multicast traffic over WLAN by using client acknowledgments to ensure delivery.

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 )

 To resolve the issue of changing the Cisco Hyperlocation detection threshold, the engineer should shut down all radios on the controller, change the Cisco Hyperlocation detection range, and then enable the radios again. This process ensures that the new threshold settings are applied correctly across the network.

To establish connectivity between a Wireless LAN Controller (WLC) and Cisco’s Connected Mobile Experiences (CMX) through Network Mobility Services Protocol (NMSP), it is essential to enable NMSP on the WLC, which facilitates communication with location-based services like CMX. Additionally, for secure communication, it is necessary to add the MAC address of the Cisco CMX server to the WLC along with its SSC (Self-Signed Certificate) key, ensuring that both devices can authenticate each other and establish a trusted connection. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The Cisco Hyperlocation feature requires enabling on both the wireless LAN controller and Cisco CMX to function correctly. This allows for precise location tracking by integrating data from both components. Additionally, if the Cisco CMX server is a virtual machine (VM), it is recommended to use a high-end VM to handle the processing demands of Cisco Hyperlocation deployments, ensuring optimal performance and accuracy.

The correct command to add a VLAN with a specific ID to a FlexConnect group in a Cisco Wireless LAN Controller (WLC) is ‘config flexconnect group BranchA-FCG vlan 30 add’. This command specifies the FlexConnect group name ‘BranchA-FCG’ and the VLAN ID ‘30’, followed by the action ‘add’, which is consistent with Cisco’s CLI syntax for WLC configuration. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

For CMX high availability deployment, enabling the virtual IP address of the primary server is critical. This virtual IP facilitates seamless failover to the secondary server without requiring DNS updates or manual intervention, ensuring uninterrupted service during primary server outages. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

When deploying Cisco Hyperlocation, it is important to enable the feature on both the wireless LAN controller and Cisco CMX to ensure proper functionality and data accuracy. Additionally, if the Cisco CMX server is a VM, a high-end VM is required to handle the processing demands of Cisco Hyperlocation deployments. References: The considerations for deploying Cisco Hyperlocation are covered in the certification guide, which emphasizes the importance of enabling the feature on both the controller and CMX, as well as the hardware requirements for the CMX server.

 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 a self-registration setup for guest/BYOD devices, when an employee tries to connect multiple devices simultaneously, the system allows the registration of all devices. However, it restricts the active connection to only one device at a time. This ensures that network resources are not overburdened by a single user connecting multiple devices. 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 address concerns about detecting spurious threats from channels not used by the wireless infrastructure, deploying APs in monitor mode (B) and local mode with WIPS submode (D) would be beneficial. Monitor mode allows APs to listen to the wireless spectrum and identify potential threats, while WIPS (Wireless Intrusion Prevention System) submode enhances the ability to detect and mitigate wireless threats. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The FlexConnect AP Upgrade feature allows for a selective upgrade process within a FlexConnect group. By not setting any master APs, the WLC will automatically select one AP of each model with the lowest MAC address to receive the upgrade directly from the controller. This ensures that the upgrade is distributed efficiently across different AP models in the group without manual intervention.
