Question 540
A network upgrade at Sable Ridge Manufacturing has two requirements: (1) publish a wireless network name for corporate users from a WLC, and (2) connect enterprise WLAN clients using a passphrase rather than per-user RADIUS credentials. Which plan correctly handles both requirements?
Explanation
Correct Answer
Both outcomes are covered: (1) The WLAN profile binds an SSID to its wireless security and policy configuration. (2) WPA2-Personal authenticates users with the configured shared key, unlike enterprise 802.1X. Neither action is a substitute for the other.
Incorrect Answers
The first step covers (1), but the second addresses distinguish tagged VLAN 30 traffic from untagged native VLAN traffic on an 802.1Q trunk. The VLAN identifier in the 802.1Q header preserves VLAN separation across shared trunks. It leaves outcome (2) unfulfilled.
The second step covers (2), but the first addresses provide an access switchport for a desktop in VLAN 20. An access port sends and receives the configured user VLAN without a data VLAN tag to the ordinary endpoint. It leaves outcome (1) unfulfilled.
Neither step is the requested pair: Treat CDP and LLDP neighbors as directly connected Layer 2 evidence is for differentiate topology discovery from actual routing reachability, and Use show interfaces trunk is for confirm which VLANs are actively forwarded over a trunk. Discovery advertisements do not prove that an IP route exists or that remote hosts are reachable. The proposed plan misses the two stated outcomes.
