Exam overview

The Cisco Implementing Cisco Wireless Advanced Solutions (300-120 WLSI) exam, administered through Pearson VUE, validates your ability to deploy, secure, and troubleshoot enterprise wireless networks across eight critical domains. The exam evaluates competency in FlexConnect infrastructure, QoS implementations, multicast distributions, location services, client security with ISE, and monitoring and hardening, serving as the concentration exam for the CCNP Wireless certification track.

Candidates are highly encouraged to possess 3 to 5 years of active engineering experience deploying, securing, and troubleshooting enterprise wireless networks utilizing Cisco Catalyst WLCs, Cisco ISE, and Cisco Catalyst Center. While there are no formal prerequisites, having a stable baseline equivalent to the Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) framework or general CCNA-level routing/switching concepts is highly recommended. The exam is ideal for wireless network engineers, CCNP Wireless candidates, and network administrators pursuing specialized wireless implementation credentials.

The 300-120 blueprint is organized into eight weighted domains, with the heaviest emphasis on Security for Wireless Client Connectivity (20%) and FlexConnect (15%). Key technical concepts include deploying FlexConnect infrastructure components and switching modes (Central vs Local), configuring FlexConnect groups and OEAP for remote deployments, implementing QoS mappings across wired and wireless borders (802.11e/WMM to 802.1p/DSCP) with Application Visibility and Control (AVC), deploying Multicast-to-Unicast mechanisms (Multicast Direct) and managing mDNS gateway roles, implementing location services with CMX and Cisco Spaces for asset tracking and rogue AP identification, structuring client profiling templates on Cisco Catalyst WLC and ISE with BYOD pipelines and Central Web Authentication (CWA), and enforcing administrative access controls with RADIUS, TACACS+, and CPU ACLs. Because the exam enforces a strict No-Backtracking policy, candidates must carefully review each answer before proceeding.

For candidates preparing for the 300-120 exam, our practice materials cover all eight weighted domains in the same proportions as the real test — from FlexConnect deployment and QoS profiling through location services configuration and ISE integration for client security. Each online practice question includes a detailed answer explanation that walks through the configuration scenario reasoning and references the relevant Cisco wireless implementation documentation, while the downloadable PDF packages the same question bank for offline review during commutes or lab sessions without stable internet.

Frequently Asked Questions

As part of Cisco's 2026 realignment of its professional wireless tracks, the older 300-430 ENWLSI exam was officially retired on March 18, 2026. On March 19, 2026, the 300-120 WLSI exam took its place. While much of the advanced deployment core (FlexConnect, QoS, Multicast, ISE integration) remains identical, the 300-120 exam formally shifts certification alignment into the dedicated CCNP Wireless badge and deepens the focus on modern centralized tools like Cisco Catalyst Center and Cisco Spaces. Our practice question bank is fully updated for the 300-120 exam, ensuring you study only the topics that appear on the current blueprint.

Cisco explicitly enforces a sequential navigation rule. Once you answer a question and click the button to proceed, that selection is finalized. You cannot park complex questions to revisit later, nor can you review your work at the end of the 120-minute limit. Candidates must make a definitive decision on each item, including hands-on configurations or labs, as they encounter them. Our online mock exam simulates this exact behavior — once you submit an answer, you cannot go back, helping you practice the time management skills needed for the real test.

The 300-120 WLSI operates as a specialization exam. To obtain the comprehensive CCNP Wireless credential, you must pass this concentration exam in tandem with the core enterprise wireless technology exam: 350-101 WLCOR (Implementing and Operating Cisco Wireless Core Technologies). You must pass both exams within a rolling 3-year window. Our PDF question bank includes a certification FAQ section to help you plan your CCNP Wireless certification path.

Cisco mandates a standard cooling-off duration of 5 calendar days before you can register and sit for the exact same exam code again. This countdown period officially begins the day following your failed testing appointment. Candidates who pass the exam are restricted from retaking the exact same code within 180 days. Our practice questions help you identify weak domains (such as FlexConnect groups, ISE integration, or location services configuration) before you sit for the real exam, reducing the likelihood of needing a retake.

Our 300-120 mock exam enforces the same strict No-Backtracking rule as the real Pearson VUE test — once you submit an answer and move to the next question, you cannot return to change it. The mock exam also mirrors the real exam's mix of multiple-choice, drag-and-drop, and performance-based lab scenarios across all eight domains, helping you build the time management skills needed to complete 55-65 questions within the 120-minute window. Detailed answer explanations after each question help you learn from configuration and troubleshooting mistakes immediately.

Yes, the complete 300-120 question bank is available as a downloadable PDF that mirrors the online practice test content. The PDF is organized by domain (FlexConnect, QoS, Multicast, Location Services, Advanced Location Services, Security for Wireless Client Connectivity, Monitoring, and Device Hardening), making it easy to focus your offline review on specific weak areas such as FlexConnect split tunneling, ISE CWA/LWA configurations, CMX/Cisco Spaces deployment, or CPU ACLs for device hardening. The PDF format is ideal for reviewing configuration scenarios and troubleshooting workflows without needing a live internet connection.

The most critical skills for the 300-120 exam include deploying FlexConnect infrastructure with Central vs Local switching modes and configuring FlexConnect groups with OEAP for remote deployments; implementing QoS mappings (802.11e/WMM to 802.1p/DSCP) and configuring Application Visibility and Control (AVC); deploying Multicast-to-Unicast mechanisms and managing mDNS gateway roles; implementing location services with CMX and Cisco Spaces for asset tracking and rogue AP identification; structuring client profiling templates on Cisco Catalyst WLC and ISE with BYOD pipelines, CWA, LWA, and downloadable ACLs; and enforcing administrative access controls with RADIUS, TACACS+, 802.1X, and CPU ACLs. Our practice questions for all eight domains reflect these priorities, with scenario-based questions that test your ability to configure and troubleshoot Cisco wireless networks.
