Cisco Designing Cisco Enterprise Wireless Networks (ENWLSD) 300-425 Exam Dumps: Updated Questions & Answers (March 2026)

 When a Wireless LAN Controller (WLC) SSO is set up between two WLCs in a service provider network, and there is a failover, the secondary WLC should ideally support the same client count as the primary. If only about half of the original client count is showing on the secondary WLC post-failover, it suggests that the WLCs had not completed the database synchronization before the primary WLC failed. This incomplete sync would result in a loss of client information, leading to a reduced client count on the secondary WLC.

To address aesthetic concerns, using enclosures can effectively conceal wireless infrastructure, such as access points, within the environment. This helps maintain the visual appeal of the area while still providing the necessary wireless coverage.

 LAG-based redundancy is chosen for its ability to provide continuous connectivity as long as one port in the LAG is operational (B), utilize the full bandwidth capacity of all the links in the LAG (E), and allow for the grouping of ports into multiple LAGs for increased redundancy and bandwidth (F). References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

 When designing a network with a DMZ and an EoIP tunnel, it’s important to ensure that the data plane is encrypted to protect the data as it traverses potentially unsecured networks. Cisco IOS-XE on the Catalyst 9800 supports encryption of the data plane, which is essential for this design.

 The Cisco 8540 Wireless Controller is designed for large enterprise and high-density environments. It has the capacity to manage up to 6000 access points, making it suitable for a multicampus architecture that needs to accommodate 4500 access points. Its high availability features ensure that all access points can be supported on one controller setup with minimal downtime.

 When configuring Cisco Prime Infrastructure, to represent the impact of a thick glass wall with an attenuation of 2dB on the RF signal, the obstacle that should be placed in the map editor is glass. This is because the material-specific attenuation values are used to model the RF signal’s behavior as it passes through different types of obstacles, and the thick glass wall’s impact is best represented by the glass obstacle in the map editor.

For an effective office site survey, it’s recommended to: A. Use a battery pack to power APs - This allows for mobility and testing in various locations without relying on fixed power sources. B. Use a drawing of the office space to mark AP and client placements - This helps in planning the optimal locations for AP installation. F. Use APs with built-in antennas - They are commonly used for site surveys as they represent the typical deployment scenario.
