clip_image002

 

A.

The client 802.1x configuration is incorrect.

B.

There is RF interference.

C.

The client WPA2 parameters are incorrect.

D.

No response is being received from the DHCP server.

E.

The client is configured with the wrong WEP key.

F.

No response is being received from the RADIUS server for 802.1x authentication.

 

Correct Answer: D

 

 

QUESTION 192

You are developing a context-aware application with customized middleware. The Cisco MSE is

configured to send northbound notifications to the middleware as well as to the Cisco WCS via SOAP/XML. You created the notification definitions via the WCS and see notifications coming in on the middleware, but you do not see notification messages showing up in the WCS.

What could be causing this problem?

 

A.

The notification receiver is not correctly configured in the WCS. Make sure the WCS is correctly configured

with a northbound notification receiver using SNMPv2 and the correct community string.

B.

The notification group does not have an MSE assigned and the MSE is not synchronized.

C.

The WCS does not understand SOAP/XML. To correct this, change the transport protocol to SNMP/plain text.

D.

The WCS does not understand SOAP/XML. To correct this, change the transport protocol to SNMP/XML.

E.

The WCS does not understand SOAP/XML. To correct this, change the transport protocol to Syslog/plain text.

F.

The WCS does not understand SOAP/XML. To correct this, change the transport protocol to Syslog/XML.

 

Correct Answer: D

 

 

QUESTION 193

Refer to the exhibit. A customer calls you to report that it is not able to carry calls on its Cisco Unified Wireless IP phones. The phones are not registering with the call manager even though it has a static IP address. Which WLC feature could be causing this problem?

 

clip_image004

 

A.

DHCP Address Assignment Required is selected on the SSID.

B.

There is a DHCP server configured on the SSID. This should not be implemented when AAA override

is selected.

C.

MFP client protection should be set to “required” on Voice SSIDs.

D.

The Option 150 IP address is misconfigured in the DHCP pool.

 

Correct Answer: A

 

 

QUESTION 194

You have been getting reports of voice disruption over wireless communications in your network. Your SSID is configured to use WPA1 with TKIP and Cisco Centralized Key Management. You see a lot of TKIP replay messages on the WLC logs.

What is the most probable reason for the voice disruptions?

 

A.

TKIP replay causes access point to reboot as a security measure. This causes voice disruptions for the

associated clients until they scan and reconnect to another AP.

B.

The TKIP countermeasure timer is putting the AP down for a specified time and causing the voice disruptions.

C.

TKIP replay activates MFP. If MFP detects the replays, it will trigger a disassociation to all wireless clients.

D.

The use of WPA1 with TKIP is the main reason for the voice disruptions. It is better to use WPA2 with AES

to avoid this problem.

Correct Answer: B

 

 

QUESTION 195

A user runs the Cisco Unified Wireless IP Phone 7921 with an AP that runs autonomous Cisco IOS Software. How does the 7921 decide whether to associate to an AP to avoid over congestion?

 

A.

The 7921 monitors the QBSS information element, which includes the Min and Max contention window

fields, and uses the information to evaluate contention and channel utilization.

B.

The 7921 monitors the QBSS information element, which includes channel load information in the beacon

and probe response frames.

C.

The 7921 monitors the QBSS information element, which includes EDCF such as queuing on the radio

egress port, and uses the information to evaluate AP load and make an association decision.

D.

The 7921 monitors the QBSS information element, which includes radio access categories and the Min

and Max contention window fields, to evaluate AP load.

 

Correct Answer: B

 

 

QUESTION 196

Two callers, using the Cisco Unified Wireless IP Phone 7921 on the same AP running autonomous Cisco IOS Software, have trouble calling each other, but the problem does not exist when they call each other using a wired IP phone. Signaling and call routing appe
ar to work correctly. What else might be causing the problem?

 

A.

On the AP, DTIM is set to 2, Beacon Interval is set to 100, and PSPF is enabled.

B.

On the AP, MFP is enabled for U-APSD, DHCP is not required, and PSPF is disabled.

C.

On the AP, WMM is enabled for U-APSD, DHCP is required, and PSK is enabled.

D.

On the AP, CAC is enabled for U-APSD, P2P-blocking is enabled, and Cisco CKM is enabled.

E.

On the AP, ARP unicast is disabled, 802.1X is configured, and WDS is enabled.

F.

On the AP, MFP is disabled, 802.1X is configured to support TSPEC, and WDS is enabled.

 

Correct Answer: A

 

 

QUESTION 197

You want to expand the services of your wireless network and add location tracking on top of voice over wireless. Although the existing wireless network offers excellent voice over wireless services, tracking accuracy is not working well enough. You decide to contract a site survey engineer. What is this engineer most likely to recommend?

 

A.

Disable 2.4 GHz and higher data rates, which interfere with location tracking.

B.

Add wireless APs that are not from Cisco, to accomplish location tracking.

C.

Add more APs to the perimeters of the floors.

D.

Choose between voice over wireless and location tracking; you cannot use both simultaneously.

E.

Install chokepoints to perform good location accuracy.

 

Correct Answer: C

 

 

 

 

 

 

QUESTION 198

Refer to the exhibit. You are a wireless specialist and have been called to inspect an existing wireless network that offers voice services. High channel utilization on 2.4 GHz has been reported. How can you solve this problem?

 

clip_image006

 

A.

Disable higher data rates 36, 48, and 54 Mb/s, which increase channel utilization.

B.

Enable lower data rates 1 and 2, to avoid sticky clients.

C.

Disable data rates 1, 2, 5.5, 6, and 9 Mb/s; set 11 Mb/s as mandatory; and leave the other higher data

rates as supported.

D.

Deselect DTPC, to avoid high channel utilization.

E.

Enable at least five mandatory data rates.

 

Correct Answer: C

 

 

QUESTION 199

To achieve location tracking, which four tasks must be completed? (Choose four.)

 

A.

Synchronize Cisco WLC or WLCs with Cisco MSE.

B.

Add Cisco MSE to Cisco WCS.

C.

Synchronize the network designs with Cisco MSE.

D.

Open UDP port 6750 between Cisco WLC and Cisco MSE.

E.
