Q12. You are working on a deployment that uses two Cisco APs as wireless bridges. One of the bridges is configured as a root bridge and the second bridge is configured as a nonroot bridge. Client A associates to the root bridge and client B associates to the nonroot bridge. Which two statements about this scenario are true? (Choose two)
A. The default setting of a bridge is nonroot bridge.

D. Two bridges that are in root mode can talk to each other.
E. In point-to-multipoint bridging, WGB is not recommended with the root bridge. WGB must be associated to the root AP in point-to-multipoint bridging setup.
Answer: A, E
Q13. Your customer wants to configure LSCs and asks for specific information about which number to configure in the text box right next to the "Number of Attempts"
.Which statement is true?
A. The default number of attempts is 100.
B. A value of 2 means that if an AP fails to join the Cisco WLC using an LSC, the AP attempts to Join the Cisco WLC using the default certificate
C. A value of 255 means that if an AP fails to join the Cisco WLC using an LSC, the AP does not attempt to join the Cisco WLC using the default .
D. A value of 3 means that if a user fails to authenticate, the user is disconnected after three retries.

Q15. Your customer is having wireless VoIP problems. When the Cisco 7925 phones roam from APtlo AP2, the voice drops out and comes back. The phones are set up for PEAP/WPA2-AES with CCKM to an external RADIUS server .The APs and WLAN are setup in FlexConnect mode. Which statement explains the issue?

Q16. Why would you enable the RFC 3578 option when adding a new RADIUS authentication server to a WLC?
A. you want to run both RADIUS and TACACS
B. to support Disconnect and Change of Authorization
C. to encrypt communications between the WLC and the RADIUS server
D. to support RADIUS key wrapping
Answer: B
Explanation:
If you are configuring a new RADIUS authentication server, choose Enabled from the Support for RFC 3576 drop-down list to enable RFC 3576, which is an extension to the RADIUS protocol that allows dynamic changes to a user session, or choose Disabled to disable this feature. The default value is Enabled. RFC 3576 includes support for disconnecting users and changing authorizations applicable to a user session and supports disconnect and change-of-authorization (CoA) messages. Disconnect messages cause a user session to be terminated immediately where CoA messages modify session authorization attributes such as data filters.
Q17. Which two statements are true based upon the output in the exhibit? (Choose two.)
A. Operation will be effective only if the video profile on the WLC is mapped to the 802.1p protocol with a tagged value of 5.
B. It is recommended to configure IP multicast on the WLC in multicast-multicast mode.
C. CAC must be enabled to avoid channel oversubscription and guarantee the configured media bandwidth.
D. In case of a violation after an RRC re-evaluation, the stream is demoted to the best- effort class.
Answer: B, ?
