Q9. A customer is deploying a Greenfield 802.11ac network on a floor that will support approximately 300 wireless devices. Which setting needs to be changed on Prime Infrastructure Planning Tool in order to predict the amount of access points the customer needs to service the new floor?
A. Data Coverage Support Margin
B. Demand Settings
C. Add AP Field
D. 802.11n Protocol Support
Answer: B

Q10. An engineer is installing a wireless network in an industrial area with extreme temperatures and a significant amount of dust. Which enclosure should be used to protect the APs?
A. ACU
B. ADU
C. NEMA
D. WLSE
Answer: C
Explanation:
Sometimes access points (APs) are located in areas where they are subject to extreme moisture, temperatures, dust and particles. These APs might need to be mounted inside a sealed enclosure. The NEMA has a rating system for these enclosures, which are generally called NEMA enclosures.

Q11. A customer has deployed an N+N redundant wireless infrastructure. In this deployment, the access points have been salt and peppered between controllers. What configuration would be necessary to cut down on the use of mobility tunnels for voice clients?
A. mobility anchor
B. KIS based CAC
C. media session snooping
D. re-anchor roamed voice clients
Answer: D
Q12. A customer has restricted the AP and antenna combinations for a design to be limited to one model integrated antenna AP for carpeted spaces and one model external antenna AP, with high gain antennas for industrial, maintenance, or storage areas. When moving between a carpeted area to an industrial area, the engineer forgets to change survey devices and surveys several APs. Which option is the best to reduce the negative impact of the design?
A. Deploy the specified access points per area type.
B. Resurvey and adjust the design.
