About the WLSI Exam

Implement advanced Cisco wireless — FlexConnect, QoS, multicast, location services, client security, monitoring, and device hardening

Conquer the CCNP Wireless implementation concentration with 250 original practice questions covering FlexConnect (switching and operating modes, FlexConnect groups and roaming, split tunneling and fault tolerance, VLAN-based central switching and Flex ACL, Smart AP image upgrade, and OfficeExtend), QoS on a wireless network (QoS schemes with wired-to-wireless mapping, the Catalyst 9800 metal profiles, per-client rate limiting and Call Admission Control, and Application Visibility and Control with NBAR2), multicast (multicast components, how multicast affects wireless, multicast on a WLAN with IGMP snooping and delivery modes, mDNS/Bonjour gateway, and Multicast Direct/VideoStream), location services (deploying CMX and Cisco Spaces with the Spaces Connector, and client, RFID-tag, interferer, and rogue tracking), advanced location services (CMX and Cisco Spaces detect-and-locate, analytics, presence services, captive portals, and connectors, location-aware guest portals and social Wi-Fi, troubleshooting location accuracy and Connector high availability, and wIPS using Cisco Catalyst Center), security for wireless client connectivity (client profiling on WLC and ISE, BYOD and guest with CWA and LWA, native supplicant and certificate provisioning, and Identity-Based Networking with VLAN/QoS/ACL authorization), monitoring (Catalyst Center reports and Assurance, alarm and rogue management, RF interferer management, and troubleshooting client connectivity across the WLC, ISE, and Catalyst Center), and device hardening (RADIUS and TACACS+ admin access controls, 802.1X access-point authentication, and Control Plane ACLs on the controller). Built to exam topics v1.2 (effective March 2026). Original practice questions.

Who Should Take This Exam?

The WLSI is designed for experienced professionals validating advanced wireless implementation skills. It is a concentration exam of the new standalone CCNP Wireless track (pair it with the 350-101 WLCOR core exam to earn CCNP Wireless) and it independently earns the Cisco Certified Specialist – Wireless Advanced Solutions credential. 3-5 years of enterprise networking experience with a wireless focus is recommended.

Typical study time: 8-12 weeks of intensive study

Exam Domains & Weights

The WLSI exam covers 8 domains. Focus your study time based on the weights below — higher-weighted domains have more exam questions.

DomainWeightPractice Qs
FlexConnect15%38
QoS on a Wireless Network10%25
Multicast10%25
Location Services10%25
Advanced Location Services10%25
Security for Wireless Client Connectivity20%50
Monitoring15%37
Device Hardening10%25
Total100%250

💡 Study tip: Security for Wireless Client Connectivity carries the most weight (20%) — master ISE-driven BYOD and guest access (CWA vs LWA, the redirect ACL and URL-redirect flow), client profiling, native supplicant and certificate provisioning, and Identity-Based Networking (VLAN/dACL/QoS authorization). FlexConnect and Monitoring (15% each) are next — know the FlexConnect switching/operating modes and the three troubleshooting tools (Catalyst 9800 RadioActive Tracing, ISE Live Logs, and Catalyst Center Client 360). The location pair (Location Services + Advanced Location Services, 20% combined) rewards knowing where CMX and Cisco Spaces each fit.

Cisco Certification Path

Cisco certs follow: Entry (CCT) → Associate (CCNA) → Professional (CCNP) → Expert (CCIE). WLSI is a concentration exam of the standalone CCNP Wireless track; pair it with the 350-101 WLCOR core exam to earn CCNP Wireless, and it independently earns the Cisco Certified Specialist – Wireless Advanced Solutions credential.

Study Tips

  1. Master the ISE security flows — CWA vs LWA, the redirect ACL plus URL-redirect and CoA reauthorization, native supplicant provisioning, and certificate provisioning are the highest-yield content in the 20% security domain
  2. Know the FlexConnect model cold — local vs central switching, connected vs standalone operation, FlexConnect groups for fast roaming and local auth, split tunneling, and OfficeExtend
  3. Learn where CMX and Cisco Spaces each fit — on-prem CMX vs cloud Cisco Spaces with the Connector, what detect-and-locate, analytics, presence, and captive portals do, and how to troubleshoot location accuracy and Connector high availability
  4. Use our practice exam — try the 20 free questions first to gauge your readiness
  5. Review explanations — don’t just check if you got it right; read why each answer is correct and why the alternatives fall short
  6. Simulate exam conditions — use the timed exam mode to practice under pressure
