Within theJuniper Mist Wireless Assurance dashboard, theCapacity SLE (Service Level Expectation) provides visibility into how well the network can handle concurrent users and traffic loads. It identifies the contributing factors, orclassifiers, responsible for degraded capacity performance such asWi-Fi interference, network issues, Ethernet problems, or authorization delays.
According to theJuniper Mist AI Operations and SLE Analytics Guide, the platform:
"Uses classifiers to break down SLE metrics and identify which network factors most heavily contribute to sub-threshold performance." In the exhibit, theWi-Fi interferenceclassifier has the longest bar reaching the full17%, clearly showing it as the largest contributor to capacity degradation. Wi-Fi interference occurs when multiple APs or nearby wireless networks overlap on the same channel, resulting in increased contention, collisions, and reduced airtime availability - all of which impact overall capacity.
Therefore, the correct answer isD. Wi-Fi Interference.
