1. According to the troubleshooting actions, choose proper troubleshooting process order.
Create a testing action plan based on the information gathered.
Clearly define the trouble reported.
If the problem has not been solved, change vanables and repeat process.
Collect data to isolate possible causes.

2. Which two options are correct according to debug output presented in the following exhibit ? (Choose two.)
A. The wireless client uses a static IP address, so "0.0.0.0 START (0)" can be found in the logs.
B. The wireless client has been successfully authenticated. Reauthentication is set to occur on an extremely aggressive schedule (every five seconds).
C. The wireless client "hangs" in probes (does not proceed with 802.11 authentication and association). It is likely that the "encryption" or "key-management" advertised in the probe response does not match.
D. Since the AP receives a probe request from the wireless client, the Access Point Functions state for the machine changes from "Idle" to "Probe."
Answer: CD

3. Lightweight Access Point Protocol or LWAPP is the name of a protocol that can control multiple Wi-Fi wireless access points at once. How does the Cisco WCS know what has happened in an LWAPP system when an AP’s interface goes down and then comes up again?
A. The Cisco WCS polls the APs and when the AP is unreachable, reports "Max retransmissions reached on AP <name>".
B. The AP sends a linkDown then linkUp trap to the Cisco WCS; these are two of the six traps defined in RFC 1215, A Convention for Defining Traps for use with the SNMP.
C. The AP cannot send a linkDown trap, as per RFC 1215, because the link is down; when the link comes back up, the AP sends a linkup trap to the Cisco WLC, which then forwards the trap to the Cisco WCS.
D. The Cisco WLC sends a trap to the Cisco WCS when it detects that an AP is down.
Answer: D

Given:
Wireless-Client (CB21) configured for SSID "CCIE-2"
Standalone AP (autonomous), configured with 3 SSID’s and 3 Data-Vlan plus the native VLAN.
AAA server configured for LEAP and EAP-FAST authentication and dynamic VLAN assignment.
Question:
Why is this wireless client not able to associate to the network?
A. VLAN assignment is only supported on the Wireless LAN Controller solution.
B. Attributes in use are not correct for VLAN assignment.
C. The DHCP server is down.
D. The encryption/key-management from the SSID/VLAN the client uses to associate must match with the SSID/VLAN the AAA server assigns during the authentication/authorization process.
Answer: D
