Demo Questions

Question 1
You are designing a WLAN for 50 branch offices that require central management. Which controller architecture do you use?
  1. per-branch local controllers
  2. anchor controllers
  3. FlexConnect controllers
  4. autonomous access points
Correct answer: C
Question 2
A customer reports that wireless clients are not able to receive multicast data from known working multicast servers on the wired network. The client is connecting at the highest mandatory wireless rate of 24 Mbps and the wireless controller is configured for multicast-unicast mode. What three actions should the engineer take next to troubleshoot the issue? (Choose three.)
  1. verify that the L3 interfaces are configured for pim sparse-dense-mode on the VLAN servicing the wireless access points as well as the wireless controller's management VLAN
  2. change the wireless controller from Multicast-Unicast mode to Multicast-Multicast mode and assign a multicast address in the 239.X.X.X/8 subnet
  3. verify that IGMP snooping is disabled on the wireless controller since the access points are handling IGMP messages from the clients
  4. verify that Global Multicast mode has been enabled
  5. make sure the highest mandatory rate is set to 54 Mbps so that the multicast traffic has sufficient bandwidth
  6. verify Multicast Listener Discovery (MLD) v1 snooping has been enabled to keep track of and deliver IPv4 multicast flows
Correct answer: ABD
Question 3
An engineer is tuning RRM parameters to improve client connectivity. Which channel band results in the best 802.11n client compatibility?
  1. UNII-2
  2. UNII-2e
  3. UNII-3
  4. UNII
  5. UNII-1
Correct answer: E
Explanation:
802.11n operates on the same channel as 802.11a. For better compatibility with 802.11n clients, it is recommended to stay on lower channels (UNII-1 band). Reference: http://www.cisco.com/c/en/us/support/docs/wireless/4400-series-wireless-lan-controllers/108184-config-802-11n-wlc.html

Question 4
A downstream packet that contains 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?
  1. No outer CAPWAP or inner QoS tagging is applied.
  2. The outer CAPWAP CoS is marked and capped and the inner DSCP maintains the original marking.
  3. No outer CAPWAP QoS tag is applied, but the original DSCP is maintained inside CAPWAP.
  4. The outer CAPWAP DHCP is marked and capped without any inner DSCP value.
Correct answer: B
Question 5
An engineer is deploying centralized wireless solution with a 5508 controller. What is the most AP licenses that can be supported?
  1. 100
  2. 250
  3. 1000
  4. 500
Correct answer: D
Explanation:
You can order Cisco 5500 Series Controllers with support for 12, 25, 50, 100, 250 or 500 APs as the controller's base capacity. You can add additional AP capacity through capacity adder licenses available at 25, 50, 100 and 250 AP capacities. You can add the capacity adder licenses to any base license in any combination to arrive at the maximum capacity of 500 APs. Reference: http://www.cisco.com/c/en/us/support/docs/wireless/5500-series-wireless-controllers/112926-5508-wlc-license.html

Question 6
Which list of characteristics must all controllers in a mobility group have in common based on best practices?
  1. mobility group name, version of controller code, Control and Provisioning of Wireless Access Points mode, ACLs, and WLANs (SSIDs)
  2. mobility domain name, version of controller code, and Control and Provisioning of Wireless Access Points mode
  3. mobility domain name, version of controller code, Control and Provisioning of Wireless Access Points mode, ACLs, and WLANs (SSIDs)
  4. mobility group name, version of controller code, and Control and Provisioning of Wireless Access Points mode
Correct answer: A
Question 7
An engineer is conducting a location readiness test and wants a selected point to be considered location-ready. Which three possible configurations reflect the minimum number of APs needed? (Choose three.)
  1. One AP is resident in each quadrant surrounding the point-in-question.
  2. One AP per 1400 sq. ft. on the map.
  3. Two APs are resident in each quadrant surrounding the point-in-question.
  4. Four APs are deployed on the floor.
  5. Three APs are within 70 feet (21 meters) of the point-in-question.
  6. Three APs are deployed on the floor.
Correct answer: ADE
Explanation:
A point in a WLAN deployment is location ready if the following are all determined to be true: At least four access points are deployed on the floor.  At least one access point is found to be resident in each quadrant surrounding the point-in-question.  At least one access point residing in each of at least three of the surrounding quadrants is located within 70 feet of the point-in-question.  Reference: http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Borderless_Networks/Unified_Access/CMX/CMX_LocFund.pdf
