When designing a WLAN network to support both voice and context-aware services, which set of
design principles should you follow?

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?

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?

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 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?

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 appear to work
correctly. What else might be causing the problem?

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?

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?

Refer to the exhibit.

A Cisco Wireless IP Phone is unable to seamlessly roam on 2.4 GHz. There are interruptions of
several seconds on each roaming. No problems are reported on 5 GHz. A full site survey for voice
has been completed on both bands.
Which Cisco WLC feature does this issue involve?

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