Exam 642-586: AWLANSE – Cisco Advanced Wireless LAN for System Engineers (update November 15th, 2015)

Why has the customer only had limited success with the current deployment to meet the data needs?

A customer brings you a previously completed site survey for the initial wireless implementation
from 12 months ago. The customer currently has six access points deployed in the warehouse.
The survey shows that the installed coverage provides for a 15-percent overlap between cells at
5.5 Mbps, and a 5-percent overlap at 11 Mbps. This solution has proven to provide adequate
coverage and roaming capabilities for the data applications. However, the customer has recently
moved to a VoIP telephony solution and has attempted to add seven Cisco 7920 wireless IP
phones with limited success. Why has the customer only had limited success with the current
deployment to meet the data needs?

Which product will support the customer requirements?

A customer is adding a new branch office with 60 access points and 120 users that requires WDS
to support a wireless VoIP application on a single subnet. Additionally, the customer requires local
authentication services to provide authentication capability in the event of a WAN failure. Which
product will support the customer requirements?
