After designing and deploying a WLAN infrastructure, you realized the CCI is causing poor performance in the 2.4 GHz band. Primarily, you’ve designed the WLAN for 5 GHz and 2.4 GHz as a best effort. You found out that the implementers didn’t 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 band?

Your customer requires a security solution in which client credentials are used and the authentication server must have a certificate with optional client certificate use. Which EAP method would be the best fit for their requirement?

A customer is acquiring a new VoWLAN system to replace their existing wired phone system. When reading about his system’s requirements, you learned that is requires 25 db of SNR to work as expected. After surveying the environment, you discovered that the noise floor is -88 dBm. What should be the minimum RSSI value to meet the system’s requirements?

What advantage provided by 802.11n and 802.11ac is not usable in 1X1:1 low-end client devices?

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 you’ve validated coverage after deployment. What is causing this issue?

When deploying a new WLAN infrastructure using PoE to power the APs, you realize that a known good AP is not powering up. You use the same cable to connect your laptop and connect without any trouble. What is the most likely reason the AP did not power up?

Which DHCP option, when required, should be configured and enabled to help APs locate their wireless LAN controller?

When deploying APs outdoors, what additional component needs to be used that is not needed indoors?

During an RFP analysis, one of the vendors mentioned that you’ll need to upgrade your Gigabit Ethernet switches to MultiGig switches to ensure support for 802.11ac and 802.11ax, which both offer data rates over 1Gbps. Why is this not sound advice?
