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

 To improve the speed of client roaming in a wireless network, especially in scenarios where applications are dropping during roams between access points, it is recommended to switch to WPA2 with AES encryption. WPA2AES provides a more robust and efficient encryption method, which can facilitate faster and more secure client handoffs between APs. This change can help mitigate issues with application drops during roaming. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, focusing on client roaming optimization and security protocols for wireless networks.

 To ensure that the guest network uses only lower rates instead of 802.11n data rates, the WMM (Wi-Fi Multimedia) policy of the WLAN should be set to disabled ©. This will prevent the use of 802.11n data rates, which require WMM to be enabled. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 If the administrator is unable to see interferers on the Cisco Prime Infrastructure maps, it could be due to the MSE (Mobility Services Engine) not being added and synchronized with Cisco Prime Infrastructure, which is essential for tracking and locating devices, including interferers. Additionally, if interferer tracking is not enabled on the MSE, it would not track or display the location of interferers on the maps. The other options, such as SNMP failure, reaching the Context Aware Service tracking limit, or inactive NSMP communication, would affect other aspects of network visibility but not specifically the tracking and display of interferers. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The Simple Certificate Enrollment Protocol (SCEP) is used to securely issue certificates to network devices in a scalable manner. When provisioning certificates on a Cisco Catalyst 9800 Series Wireless Controller using a third-party CA server, SCEP is the protocol that facilitates this process. It allows the controller to request and install certificates automatically, which is essential for establishing secure communications within the network. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

A rogue AP with open authentication poses a high security risk as it does not require a password, making it easy for unauthorized users to connect. If the rogue AP accepts clients, it can potentially capture sensitive data from those clients. A foreign SSID indicates that the AP is not part of the managed network and could be maliciously installed to lure unsuspecting users. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, focusing on security risks associated with rogue APs.

The issue with duplicate client entries from iOS clients with the private MAC address feature enabled can be resolved by breaking the high availability using the cmxha config disable command and upgrading the primary and secondary individually. This approach allows for each appliance to be upgraded without affecting the high availability pair’s synchronization and operation. References: The solution is supported by best practices for upgrading Cisco appliances in a high availability configuration, as outlined in the CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

When an IT department needs to locate a stolen laptop using its MAC address, enabling Location History for Clients on the Mobility Services Engine (MSE) is crucial as it allows for historical tracking of client devices’ locations. Furthermore, Client location tracking must also be enabled on the MSE; this feature actively tracks and updates the current position of all client devices in real-time. Both settings are necessary to provide a comprehensive view of where the laptop has been over time and its current location within the wireless network’s coverage area. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

When implementing Cisco Identity-Based Networking on a Cisco AireOS controller with two ACLs where one is applied directly on the WLC interface and another referenced by ISE for a specific group policy, the resulting ACL for a user in that group would be a combination of both ACLs. The BASE_ACL applied on the corporate_clients interface acts as the default ACL for all corporate clients, while HR_ACL is specific for Human Resources users. When a Human Resources user connects, HR_ACL takes precedence but does not replace BASE_ACL; instead, it appends its rules to those of BASE_ACL resulting in an aggregated set of rules from both ACLs. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

To prevent the network from a Layer 2 flooding of multicast frames and ensure a seamless transfer of multicast data to the client when roaming, IGMP snooping should be enabled on the WLC. This feature allows the WLC to monitor and control multicast traffic at Layer 2, preventing unnecessary multicast forwarding.

Disabling DHCP proxy on the Cisco WLC and running the ip helper-address command under the VLAN interface to point to DHCP and the two ISE servers is the recommended action. This allows direct communication between clients and DHCP/ISE servers, which is necessary for accurate device profiling.

 The benefit of using dual SSIDs with a captive portal on the onboard SSID compared to a single SSID solution is the ability to restrict allowed device types. With a dual SSID setup, one SSID can be used for onboarding new devices with a captive portal that can enforce policies and check the device type before allowing access to the main SSID. This helps in maintaining a secure and compliant network environment. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 When a network engineer receives an alert about a rogue AP and determines it is a security threat inside the campus, the fastest way to disable it is by updating its status in Cisco Prime Infrastructure to ‘contained’. This action instructs the system to prevent the rogue device from communicating with other devices on the network, effectively isolating it without having to physically locate or manually disable it. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

To meet the requirement of allowing employees to easily onboard their personal devices and visitors to connect without reception desk intervention, configuring a self-registration guest portal on Cisco ISE is the appropriate solution. This feature enables guests to create their own accounts and gain network access, streamlining the process for both employees’ personal devices and visitors. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

The command in question is typically used to configure the switch to interact with a RADIUS server for session tracking purposes. The RADIUS server keeps track of authenticated sessions, ensuring that they are still active and monitoring for any changes in status. This is crucial for maintaining network security and ensuring that only authorized users have access to network resources.

 In Cisco CMX, to view active RFID tags, the engineer needs to enable the tracking of these tags within the system settings. This is typically done by selecting an option that allows for RFID tag tracking, which makes them visible on location-based services like the Detect and Locate window of Cisco CMX. By enabling this feature, the system starts to interpret signals from RFID tags and displays their location accordingly. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

To rename access points and add them to the correct AP groups on a wireless controller, the minimum custom attributes required using Cisco ISE TACACS is role1=WIRELESS. This role provides the necessary permissions for read/write access to wireless-related configurations. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

 For a large company requiring support for 32 VLANs for different departments, the most efficient solution is to configure one single SSID and use Cisco ISE for dynamic VLAN assignment based on user roles. Cisco ISE can classify users into different groups and assign them to the appropriate VLANs. This approach reduces the complexity of managing multiple SSIDs and simplifies the user experience while maintaining a high level of security and network segmentation. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

In Cisco Prime Infrastructure, the report that must be created to present a list of all rogue APs with a high severity score to senior management is the “Rogue APs” report. This report provides detailed information about rogue access points detected in the network, including their severity score, which helps in assessing the potential risk they pose to the network security. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)
