Show Answer

Question # 5

An engineer added an AP to a deployment after a post-installation site survey. Theengineer then notices an increase in co-channel interference and retransmissions. Whichtwo features help mitigate the issue? (Choose two.)

A. Cisco Compatible Extensions  
B. Transmit Power Control  
C. Enhanced Distributed Channel Access  
D. Coverage Hole Detection  
E. Dynamic Channel Assignment

Question # 6

A customer asks an engineer to explain the concept of mobility domains and mobilitygroups. Which statement does the engineer respond with?

A. A mobility group does not constrain the distribution of security context of a client andalso does not constrain AP fail-over between controllers when the WLC are in the samemobility domain. 
B. If WLCs are in the same mobility domain, they communicate with each other but, if ananchor WLC is present it must be in the same mobility domain for communication to bepossible.
C. If WLCs are in the same mobility domain, they communicate with each other. Mobilitygroups constrain the distribution of security context of a client and also constrain AP failover between controllers. 
D. WLCs do not need to be in the same mobility domain to communicate with each other.Mobility groups constrain the distribution of security context of a client and also constrainAP fail-over between controllers.

A. bigger channel width  
B. lower throughput  
C. 2.4 GHz signal congestion  
D. higher RF re ection  

Show Answer

Question # 8

An engineer is configuring a centralized set of controllers for separate facilities. Which twoCisco wireless architectures must be used to ensure flexible sizing of WLAN to VLANmappings? (Choose two.)

A. interface group  
B. mobility group  
C. AP group  
D. controller group  
E. RF group  

Show Answer

Question # 9

A customer called with a requirement that internal clients must be on different subnetsdepending on the building they are in. All access points are operating in local mode and willnot be modified, and this is a single controller solution. Which design approach creates thedesired result?

A. Create AP groups for each desired location, map the correct VLANs to the internalSSID, and add the access points for that location.
B. Create an SSID place it to the desired VLAN under WLANs and configure 802.1x in ISEto assign the correct VLAN based on the SSID from which the client is authenticating
C. Create FlexConnect groups, place the access points in, and set the correct VLAN toSSID mapping based on location. 
D. Create mobility anchors for the SSID and on the controller under the internal SSIDcreate a foreign map to the desired VLAN based on location.

Question # 10

An engineer is setting up the WLC to support a high-density design for a lecture hall. Theengineer must modify the existing high-density RF protocol to obtain a smaller cell size.Also, the clients must connect to the nearest AP using the highest possible data rates.Which setting allows this design?

A. AP load balance  
B. client distribution  
C. power threshold  
D. RX-SOP threshold
