QUESTION 1
During the site survey kick-off meeting with your customer, they ask why you need to verify the existing network infrastructure. Which two reasons do you give them? (Choose two.)

A. You need to verify the make, model, and software versions of all the equipment that will connect to the WLAN components in order to ensure compatibility.
B. You need to verify that the equipment the WLAN components will connect to has sufficient memory capacity to support the additional WLAN connections.
C. You need to verify that there are sufficient switch ports to support the new WLAN connections.
D. You need to verify that the switches the WLAN components will connect to can supply 802.3af inline power, and that they have sufficient ports to support all the new WLAN devices.
E. Depending on the type of APs that are planned for, the deployment may require different types of PoE to be supplied by the LAB switches.

Answer: C,D


QUESTION 2
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 amount 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 distributed deployment method in each building MDF with the N + N redundancy method.
B. Use the centralized deployment method in the data center with the N + N + 1 redundancy method.
C. Use the distributed deployment method in each building MDF with the N + 1 redundancy method.
D. Use the centralized deployment method in the data center 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 centralized deployment method in the data center with the N + N redundancy method.

Answer: B

QUESTION 5
In evaluating a post-installation WLAN deployment, problems are occurring when a client roams from one AP to another. The client bounces back and forth between APs. Which three items can be checked to resolve this issue? (Choose three.)

A. When a client roams from one AP to the next, check the client RSSI and SNR levels for both APs at the roaming point.
B. Simplify 802.1X/EAP by moving from external RADIUS to local authentication.
C. Verify the authentication being used for the same test that the client would use under production.
D. Check if the roaming settings in the AP are set properly for non-CCX clients.
E. Check the RF levels of the first AP as the client moves toward the second AP.
F. Check that the client roaming parameters are set properly.

Answer: A,C,E
