Q4. 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?
A. No outer CAPWAP or inner QoS tagging is applied.
B. The outer CAPWAP CoS is marked and capped and 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.
Answer: B
Q5. You have a customer that is building a new campus of four 3-story buildings that you have just completed the site survey for. The customer is interested in the mount of rack space they will need to allocate in either the building MDF or in the data center for controllers. Each building is going to require 75 APs to support voice and data. How should the controllers be deployed to provide the least number of controllers, the highest redundancy, and the easiest management?
A. Use the centralized deployment method in the data center with the N + N redundancy method.
B. Use the centralized deployment method in the data center with the N + 1 redundancy method
C. Use the centralized deployment method in the data center with the 1 + 1 redundancy method and clientSSO.
D. Use the distributed deployment method in each building MDF with the N + 1 redundancy method.
E. Use the distributed deployment method in each building MDF with the N + N + 1 redundancy method.
F. Use the distributed deployment method in each building MDF with the N + N redundancy method.
Answer: C

Q7. When designing a WLAN, AP placement is important. Which option describes how to rank the density of APs needed to support location services versus data and voice services?
A. Data services have the lowest density of APs compared to location services, which has the highest density.
B. Data services have a lower density of APs compared to location services, but more than voice.
C. Voice services have the highest density of APs over location and data services.
D. Voice and data services require a higher density of APs than location services.
Answer: A
Q8. Which two factors influence the density of APs in a data-only WLAN environment? (Choose two.)
A. the number of clients that will roam through the facility
B. the type of controller chosen
C. the defined coverage area and customer needs
D. the number of APs dedicated to voice services
E. channel reuse and WLAN bandwidth
Answer: A,E
Q9. An engineer is assigned to replace an older data-grade autonomous wireless network with a Cisco controllerbased wireless network to meet Voice over WLAN needs. The customer also wants all existing cable infrastructure to be reused and no new cable be specified. How should the engineer respond to the customer’s requirements?
A. Implement the wireless network with the restraints and decrease the TPC neighbor threshold to increase Txpower to provide overlapping cell coverage at sufficient SNR to provide for Voice over WLAN service.
B. Implement the wireless network with the restraints and utilize high-gain antenna to provide overlapping cellcoverage at sufficient SNR to provide for Voice over WLAN service.
C. Inform the customer that the network will not likely function as desired and a post install survey with thepossibility of some new cable would be recommended.
D. Inform the customer that it is not possible to provide coverage and quality for Voice over WLAN usingexisting AP locations and an entire overbuild will be necessary.
Answer: C
Q10. What is the optimal distance between APs for location services without considering the physical environment?
A. 10 to 25 feet
B. 90 to 120 feetÂ
C. 50 to 70 feet
D. 80 to 100 feet
Answer: C
