Cisco WLCOR 350-101 study guide
Cisco WLCOR 350-101 · Work through your exam, one topic at a time.
The Cisco WLCOR 350-101 exam is a Cisco wireless exam aimed at network professionals who design, deploy, and operate enterprise Wi-Fi. Candidates typically already work with controllers, access points, and campus switching, and are looking to validate that they can reason about RF behavior, plan coverage, and keep a wireless network healthy after cutover. The Cisco WLCOR 350-101 study guide has 6 sections and about 1,918 words.
01Wireless Fundamentals and RF Principles
dBm is absolute power referenced to 1 mW (0 dBm = 1 mW, 20 dBm = 100 mW, 30 dBm = 1 W). dBi is relative antenna gain.
374 words, about 2 min02Wireless Design and Site Survey Concepts
Design begins with a business requirement, and the first fork is coverage-driven versus capacity-driven . Coverage designs (warehouses, outdoor yards, sparse IoT) use fewer APs at higher power.
317 words, about 2 min03Cisco Wireless Architectures and Deployment Models
Cisco wireless spans autonomous APs (self-contained, configured individually), the unified/CUWN model (lightweight APs joined to a WLC), FlexConnect (unified control with local data switching), Catalyst 9800 controllers on IOS-XE (including embedded wireless controllers on Catalyst 9000 switches), cloud-managed (Meraki), and SD-Access wireless where the fabric handles client mobility. Know which plane each model splits: in local mode, both control and client data are tunneled to the controller; in FlexConnect, control stays with the WLC while data is switched locally at the AP.

A client joins in stages: probe/scan (active or passive), open 802.11 authentication, association, security (802.1X/EAP or PSK with the 4-way handshake), then DHCP and ARP. A failure at any stage looks like “can't connect,” so troubleshooting must identify the stage - association failures point at RF or configuration, while DHCP failures point at VLAN or anchor path issues.
324 words, about 2 min05Wireless Security and Policy
WPA2-Personal uses PSK; WPA2-Enterprise uses 802.1X with EAP (EAP-TLS with certificates, PEAP-MSCHAPv2 with credentials, EAP-FAST) terminated at RADIUS. WPA3-Personal replaces PSK with SAE to defeat offline dictionary attacks, and WPA3-Enterprise offers a 192-bit suite requiring certificate-based EAP-TLS.
275 words, about 1 min06Wireless Operations, Monitoring, and Troubleshooting
Effective troubleshooting follows a fixed order: physical/RF layer, then AP join, then client join, then policy/path. On the RF side, monitor channel utilization , noise floor , retry rate , and client SNR .
