Q3. Which two option describe implication of deploying autonomous APs in repeater mode? (Choose two)
A. The Ethernet port is disabled in repeater mode
B. You can configure multiple VLANs on repeater access point
C. You should disable Cisco Aironet extensions on the parent(root) AP and on the repeater APs
D. The infrastructure SSID should be assigned to the native VLAN
Answer: A, D
Q4. 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.
Q5. 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, ?
Q6. An autonomous AP is configured with the infrastructure –client command. What is this command used for?
A. to allow more than 20 client associations
B. to send reliable multicast traffic
C. to enable multiple VLANs to cross the bridge link
D. to allow only infrastructure device associations
Answer: B
