In a convention center, you have received complaints about the WLAN infrastructure. At this
moment, the are only two APs in one auditorium. After analyzing the situation, you determined that
there are more client devices that the infrastructure was designed for. There are only two APs to
support more than 300 devices using the Wi-Fi at the same time. What should you do to make the
Wi-Fi work as expected?
While performing a validation site survey, you realize that overlapping channels are being used on
the 2.4 GHz bad due to the automatic channel assignment algorithm of the WLAN infrastructure.
What should you do to prevent this?
During a validation site survey, you realize that the installers mounted some of the APs above the
ceiling. They said that this was a request from the building architect due to aesthetics constraints.
During the requirements gathering, you werent advised about any aesthetics constraints from the
main stakeholder of the project. What should you do in this case?
Who should be in the final meeting from the customer-side after successfully implementing a WLAN
What are the deliverables to your customer after successfully implementing a WLAN infrastructure?
You have performed a validation site survey after deploying a WLAN infrastructure that is an All-
Wireless-Office. One specific application of your customer is experiencing delay when using the
application after moving from wired connectivity. After your validation, you realized that all APs are
using 80 MHz channel-widths instead of 20 MHz on the 5 GHz band, as it was designed. What can be
done to resolve the delay on this application?
After designing and deploying a WLAN infrastructure, you realized the CCI is causing poor
performance in the 2.4 GHz band. Primarily, youve designed the WLAN for 5 GHz and 2.4 GHz as a
best effort. You found out that the implementers didnt follow your guidelines when configuring the
WLAN infrastructure. What can you do to minimize as much as possible the CCI impact in the 2.4 GHz
After deploying a 5 GHz-only WLAN infrastructure in the USA, using 20 MHz channel-widths and all
25 available channels, one of the managers of the company brings his 802.11n tablet to the office to
test the Guest SSID. While testing, there were several spots where we would get poor RSSI (below -
80dBM) or none at all. You checked the WLAN infrastructure and all APs are up and running and
youve validated coverage after deployment. What is causing this issue?
During lunch time in the break room of a company, Wi-Fi connectivity on the 2.4 GHz band is
intermittent. Every other time of the day, it works fine. Whats the likely cause of this issue?
You are validating association capabilities from clients to an 802.1X/EAP secure SSID. The RADIUS
servers IP address is 10.100.50.25 and the default RADIUS authentication port is used. When testing
them, none of the clients are able to associate to the SSID. Troubleshooting the WLAN infrastructure,
you found out that the server is up and the RADIUS service is up as well, but the authenticator is not
able to communicate properly with the server. Whats your next troubleshooting step?
