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?
⚠ Common exam trap
Cisco often tests the ability to read the 'Status' column accurately, as candidates may mistakenly assume all listed WLANs are active or confuse the 'Security' column with the 'Status' column.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
WLAN 3 is not operational because it is disabled.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
All WLANs are currently active and serving clients.
Why it's wrong here
The IoT WLAN shows Status Disabled, so it is not serving clients; only three of the four WLANs are active. Assuming every listed WLAN is operational is tempting because the summary lists all configured entries, but the Status column distinguishes enabled from disabled.
- ✓
WLAN 3 is not operational because it is disabled.
Why this is correct
The Status column shows WLAN 3 as Disabled, meaning the WLAN is administratively shut down and will not broadcast or accept client associations. Its SSID, security and interface settings remain configured but inactive until the WLAN is enabled.
- ✗
The Guest WLAN uses WPA2 security.
Why it's wrong here
The Guest WLAN's Security column reads Open, so no WPA2 encryption is applied there; WPA2 appears only against Corporate, IoT and Management. Open is tempting because guest networks often use a captive portal, but that is a Layer 3 web-authentication overlay, not WPA2, and the output records the Layer 2 security type only.
- ✗
The Management WLAN is on the guest-vlan interface.
Why it's wrong here
The Management WLAN (ID 4) maps to mgmt-vlan, not guest-vlan, which belongs to the Guest WLAN. Reading across the wrong row is tempting because both are enabled WPA2 WLANs, but the Interface column pairs each SSID with its own VLAN.
