Question:1 Which debug command could determine whether an AP is registering with a WLC or not? A. debug lwapp ap {AP-MAC} enable B. debug wlccp dump C. debug lwapp events enable D. debug wlccp dump enable

Answer: C Question:2 Which two statements best describe hidden node problems? (Choose two.) A. Hidden node problems can be diagnosed and verified by enabling CTS to Self. B. The 802.11 MAC frame exchange protocol addresses these problems by adding two additional frames to each frame

exchange (a RTS and CTS frame). C. 802.11 WLAN media access is based on CSMA/CA. Therefore, every data frame needs to be acknowledged by

the receiver. D. Hidden node problems occur because each WLAN STA cannot be expected to communicate directly with every

other WLAN STA.

Answer: B, D Question:3 Do you know how many WMM access categories there are, and how they relate to the IEEE 802.1D priority classification? A. There are two access categories: Best Effort and Voice. IEEE 802.1D, SVP, or CDP determine which access category

is used. The access category used determines which EDCA timing parameters are used for transmitting the frame. B. There are eight WMM access categories that directly correlate to the IEEE 802.1D priority classification. The access

category used determines which EDCA timing parameters are used for transmitting the frame. C. There are four WMM access categories: Best Effort, Background, Video, and Voice. A fixed mapping of priority

information carried in the 802.1D Priority field to those four queues is defined by the Wi-Fi Alliance, together with suggested uses for each priority that are consistent with the suggested uses in 802.1D.

D. WMM access categories are part of the 802.11i AAA security standards, and define the different levels of client access in WPA, and WPA2. They have no relationship to IEEE 802.1D.

Answer: C Question:4 Which two technologies can the IEEE 802.11h amendment introduce? (Choose two.) A. HCCA B. DFS C. EDCA D. TPC

Answer: B, D Question:5 Study the following exhibit carefully. Configure this client supplicant and AAA server for PEAP-MS-CHAPv2. According to this debug and show output, which device is causing this client to be unable to connect and why?


A. The client supplicant: it is not configured for dot1x B. The RADIUS server: it provides the wrong server certificate (missing enhancement key usage field) C. The AP: it is misconfigured, because the RADIUS server port configuration is incorrect D. The client supplicant: due to an invalid Protected Authentication Credential

Answer: A Question:6 Which action should be taken to collect and view a remote WLAN packet capture by use of a supported packet analyzer from an AP? A. Change the AP mode to Sniffer, create a remote adapter with the Cisco WLC management IP on a packet analyzer B. Change the AP to Sniffer mode, specify a time interval, and read packet captures from Cisco WLC management C. Change the AP mode to Sniffer, configure the server IP address on the AP radio, and create a remote adapter with the

Cisco WLC management IP on a packet analyzer D. Change the AP to Sniffer mode, download a capture from the Cisco WLC, and open the capture with a packet

analyzer

Answer: C Question:7 After examining the output from the show wlccp ap command on your infrastructure AP, you discover that the AP is registered with the WDS AP. Then you observe the output of the show wlccp wds ap command on the WDS and find that the AP is registered. After reaching this infrastructure AP, how will authentication request traffic from wireless clients flow? A. 1.Traffic will be forwarded to the WDS via WLCCP. 2.The WDS will send the authentication requests to the RADIUS

server. 3.The WDS will receive the server response. 4.The WDS will communicate the status back to the


infrastructure AP. 5.The infrastructure AP will add the client to the association table if an access-accept has been received from the RADIUS server.

B. 1.Traffic will be forwarded to the RADIUS server. 2.If an access-accept is received from the RADIUS server, the infrastructure AP will notify the WDS AP, so that the WDS AP can track the client for the purposes of inter-AP roaming. C. 1.Traffic will be forwarded to the WDS via WLCCP. If the client is already in the WDS mobility

table, the WDS will notify the infrastructure AP and no further action will be taken. If the WDS does not find the client in its mobility table, the following steps will be taken. 2.The WDS will notify the infrastructure AP. 3.The infrastructure AP will forward the traffic to the RADIUS server. 4.If the infrastructure AP receives an access-accept from the RADIUS server, it will notify the WDS.

D. 1.Traffic will either be forwarded to the locally defined RADIUS server, or sent to the WDS via WLCCP. This can be set up on a per-SSID basis.

Answer: A Question:8 Which statement best describes shown Sniffer trace? A. Frame-3 is an invalid packet. BSSID is missing and duration is the same as in frame-1 (=17) although those two

packets have different data-lengths, 48 versus 66 bytes. B. Frame-3 is a retransmission of frame-1 because the corresponding ACK (frame-2) is not protected (protected-

flag in frame-2 is set to zero.) C. STA with MAC address 00:1b:77:05:4a:b9 is associated to two AP's ("Solid 802.11 redundancy");

therefore, we see the all data packets duplicated. D. STA with MAC address 00:1b:77:05:4a:b9 is associated to a Repeater-AP with MAC address 00:1d:45:7e:cf:50.

The Repeater-AP is associated to Root-AP with MAC address 00:1d:a1:90:c3:20.
