SY0-301 Question #535: Real Exam Question with Answer & Explanation
The correct answer is D: A site survey was not conducted. A wireless site survey assesses the physical environment to determine optimal placement of access points, channel assignments, transmit power levels, and coverage zones. Without one, deploying too many APs in close proximity causes co-channel interference (multiple APs broadcasti
Question
Options
- AThe old APs use 802.11a
- BUsers did not enter the MAC of the new APs
- CThe new APs use MIMO
- DA site survey was not conducted
Explanation
A wireless site survey assesses the physical environment to determine optimal placement of access points, channel assignments, transmit power levels, and coverage zones. Without one, deploying too many APs in close proximity causes co-channel interference (multiple APs broadcasting on the same or overlapping channels) and adjacent-channel interference, which degrades performance and causes random disconnections. This is a classic high-density deployment mistake. The 802.11a standard, MIMO technology, and MAC address registration are irrelevant to this symptom - the root cause is the unplanned, unsurveyed over-deployment of access points.
