Wireless questions on the CCNA cover 802.11 standards (ax/ac/n), WPA3, SSID/BSSID concepts, WLC architecture (FlexConnect, local switching), and client connectivity troubleshooting. These are mostly MCQ and multi-select.
Start Scenario PracticeDrag and drop the steps of WPA3 client authentication process into the correct order, from first to last.
Explanation: WPA3 uses Simultaneous Authentication of Equals (SAE) handshake. The client first sends an SAE commit to the AP, the AP responds with its own SAE commit, then both compute a shared key. Next, the client sends an SAE confirm message, and finally the AP sends its SAE confirm to complete authentication.
Drag and drop the steps of 802.11r Fast BSS Transition (FT) roaming steps into the correct order, from first to last.
Explanation: 802.11r FT roaming uses a fast handshake. The client sends an FT Authentication request to the new AP, which replies with an FT Authentication response. Then the client sends an FT Reassociation Request, the new AP confirms, and finally the client installs the PMK keys.
A network engineer runs the following command on a Cisco WLC: WLC# show wlan summary WLAN ID SSID Status Security Interface 1 Guest Enabled Open guest-vlan 2 Corporate Enabled WPA2 corp-vlan 3 IoT Disabled WPA2 iot-vlan 4 Management Enabled WPA2 mgmt-vlan Based on this output, what can be concluded?
Explanation: The 'show wlan summary' output clearly shows that WLAN 3 (IoT) has a Status of 'Disabled', meaning it is not operational and cannot serve clients. Only enabled WLANs can transmit beacons and accept client associations. Therefore, option B is correct because a disabled WLAN is effectively non-functional.
Drag and drop the steps of the CAPWAP discovery and join process between a lightweight AP and a WLC into the correct order, from first to last.
Explanation: The CAPWAP process starts with the AP obtaining an IP address (via DHCP), then discovering the WLC (via DHCP option 43 or DNS). The AP sends a Discovery Request, the WLC replies with a Discovery Response, and finally the AP sends a Join Request to establish the control tunnel.
Which two statements about Cisco Wireless LAN Controller (WLC) high availability (SSO) are true? (Choose two.)
Explanation: SSO uses a pair of WLCs in active/standby mode with stateful failover. The standby maintains synchronized client and AP state. A Layer 2 link is required between the two WLCs for the redundant management interface. SSO does not require identical hardware models, but they must be from the same platform family.
