QUESTION 122
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

A. By default, the historical data is archived for 30 days.
B. The history of an element is recorded if it moves more than 5 meters (or 15 feet). C. The history of an element is recorded if it moves across floors.
D. History logging is enabled by default.
E. An element is removed from the tracking table after one hour of inactivity. Correct Answer: AC Section: (none) Explanation Explanation/Reference: genuine answer. QUESTION 124
When designing a WLAN network to support both voice and context-aware services, which set of design principles should you follow?
A. An AP must be placed at the perimeter and in each of the four corners of the floor. All APs must be enabled to ensure proper coverage on the floor to provide - 67 dBm, 20 percent cell overlap, and 19 dB channel separation.
B. An AP must be placed at the perimeter and in each of the four corners of the floor. Some APs may be disabled to ensure proper coverage on the floor to provide -67 dBm, 20 percent cell overlap, and 19 dB channel separation.
C. An AP must be placed at the perimeter and in each of the four corners of the floor to ensure proper coverage on the floor to provide -67 dBm, 20 percent cell overlap, and 19 dB channel separation. Some APs may be in monitor mode.
D. If a conflict occurs between the AP placement for voice design and for context-aware location design, then the voice design should take precedence, to protect against delays and dropping of sensitive voice traffic.
E. In a design that includes both voice and context-aware services, voice design always requires more APs to be deployed to ensure -67 dBm coverage, 20 percent cell overlap, 19 dB channel separation, and proper capacity planning.
F. In a design that includes both voice and context-aware services, voice design should take precedence to avoid co-channel interference, which can negatively affect voice quality. Voice design also requires -67 dBm coverage, 20 percent cell overlap, and 19 dB channel separation, which is more difficult to achieve. Correct Answer: C

support fast secure roaming while maintaining a scalable deployment? A. The controller supports PKC, so use WPA2 802.1X.
B. The controller does not support PKC, so use WPA2 PSK. C. The controller does not support OKC, so use WPA2 PSK.
D. The 7925 does not support WPA2 with Cisco CKM, so use WPA2 PSK. E. The 7925 supports WPA2 with Cisco CKM, so use WPA2 802.1X. F. The 7925 supports PKC, so use WPA2 802.1X.

QUESTION 126
To support efficient bandwidth utilization for broadcasting multicast packets to all WLANs on the AP, which two mechanisms can you configure on the Cisco WLCs? (Choose two.)
A. VideoStream can be used to convert multicast transmissions to broadcast transmissions at the AP, to enable the AP to receive ACKs from the clients and to determine the frames that need to be retransmitted.
B. VideoStream can be used to convert multicast transmissions to unicast transmissions at the AP. The same data rate will be used, but the unicast stream allows the AP to receive ACKs from the clients and to determine the frames that need to be retransmitted.
C. RRC in a Cisco WLC will use channel utilization as a metric to determine capacity and perform admission control, but it does not deny requests that would cause oversubscription.
D. RRC in a Cisco WLC will use channel utilization as a metric to determine capacity and perform admission control, and it denies requests that would cause oversubscription by sending SAP messages to clients on drop.
E. VideoStream can be used to convert multicast transmission to unicast transmission at the AP.
Because of the unreliable nature of wireless media, no ACKs are expected from the clients; however, unicast transmission will effectively reduce multicast PLR to between 0.1 and 0.5 percent.
F. VideoStream can be used to convert multicast transmission to unicast transmission at the AP, to enable the AP to receive ACKs from the clients and to determine the frames that need to be retransmitted.
