A downstream packet containing a DSCP value arrives at the WLC Ethernet interface from the wired source network. The WLC is configured for QoS WLAN 802.1p mapping. How does the WLC treat the CAPWAP QoS marking when leaving the controller interface for the respective AP and final wireless client destination?

• A.No outer CAPWAP or inner QoS tagging is applied.
• B.The outer CAPWAP CoS is marked and capped while the inner DSCP maintains the original marking.
• C.No outer CAPWAP QoS tag is applied, but the original DSCP is maintained inside CAPWAP.
• D.The outer CAPWAP DHCP is marked and capped without any inner DSCP value.

A customer wants FSR and certificate-based authentication. The solution must be simple to deploy. Which method should be used to meet the requirements?

• A.EAP-FAST
• B.PEAP-MSCHAPv2 machine authentication
• C.PEAP-MSCHAPv2
• D.EAP-TLS

A support engineer received a ticket involving issues with voice over wireless. The customer has asked the engineer to verify their wireless deployment for voice utilizing their WCS server. What is a capability of the WCS voice readiness tool?

• A.non voice SSID contention graphs
• B.voice statistics via call re-play
• C.call location tracking
• D.Traffic Stream metric reporting

During the testing and verification phase of an 802.11n deployment, an employee wants to be able to stream video at a much faster rate than the previous 802.11a/b/g deployment. What 802.11n capability can be utilized for this?

• A.Clients are able to utilize High-Rate Direct Sequence Spread Spectrum (HR-DSSS) to reach higher data-rates, which in turn allow for much faster video streaming.
• B.Clients can utilize ClientLink which allows them to use the signal received from 802.11n access points on its various radio chains to perform multi-ratio combining.
• C.Clients can make use of MIMO to aggregate the data sent from the access points whether 802.11n or 802.11a to create a higher throughput network.
• D.Access points and clients are capable of utilizing spatial-multiplexing, multi-ratio combining, and transmit beamforming, which allows for a more efficient wireless spectrum that can utilize higher data-rates.
