Question 91

When deploying a new WLAN infrastructure using Power over Ethernet (PoE) to power the access points (APs), you find that a known good AP is not powering up. You connect your laptop using the same cable without any issues. What is the most likely reason the AP did not power up?

    Looking at a client radio specification sheet that states Receive Sensitivity of #82 dBm @ 18 Mbps would mean:
  • Question 93

    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?

    If you choose to recommend dynamic channel assignment for the APs in your WLAN design what action should you also recommend'?
  • Question 95

    What is the minimum PoE budget needed on a switch to support 6 (six) APs that can only be powered using IEEE 802.3at if no other details are provided?
