NEW QUESTION # 116
When setting up a new Mist organization, what is the recommended first step for structuring your sites and configurations?
Answer: C
NEW QUESTION # 117
As a Wi-Fi administrator of a large enterprise, you are asked to deny access from guest WLANs to the internal resources of your corporate network. Which statement is correct in this scenario?
Answer: C
Explanation:
WxLAN policies in Juniper Mist allow you to define access rules based on labels. By labeling guest users and corporate resources separately, you can create a WxLAN policy that explicitly denies guest-to-corporate traffic, ensuring proper network segmentation and security.
NEW QUESTION # 118
Referring to the exhibit, you asked Marvis to troubleshoot a client. In this scenario, what did Marvis determine?
Answer: C

NEW QUESTION # 119
Which statement correctly describes adjacent channel interference (ACI)?
Answer: D
Explanation:
In wireless networking,Adjacent Channel Interference (ACI)occurs when two or more access points transmit onpartially overlapping RF channels, causing their signals to interfere with one another. In the context ofJuniper Networks Mist AI Wireless, ACI is a critical RF condition that negatively impacts client performance and service-level expectations (SLEs).
ACI is most commonly observed in the2.4 GHz band, where only three non-overlapping channels (1, 6, and
11) are available. When access points are configured on channels such as 1 and 3, or 6 and 8, their frequency spectra overlap. This overlap results in corrupted frames, increased retransmissions, higher latency, and reduced throughput for connected clients. Unlike co-channel interference, ACI introducesuncoordinated interference, which is more damaging to overall network efficiency.
Mist AI Wireless continuously analyzes RF telemetry collected from access points and clients to identify ACI conditions. Using machine learning and RF intelligence, Mist can detect excessive retries, PHY errors, and degraded airtime efficiency associated with overlapping channels. These findings are surfaced throughMarvis AI insightsand RF-related SLE degradation indicators, allowing operators to quickly identify misconfigurations.
The incorrect options can be explained as follows:
* Option Adescribes a properly designed RF environment with non-overlapping channels, which does not cause ACI.
* Option Crefers toco-channel interference (CCI), where access points share the same channel and rely on contention-based access mechanisms.
* Option Dis too broad; simply operating in the 2.4 GHz band does not inherently cause ACI unless overlapping channels are used.
To mitigate ACI, Mist best practices recommend usingnon-overlapping channels, minimizing channel width, and favoring the5 GHz and 6 GHz bandswhere more clean spectrum is available. Therefore, the correct description of ACI istwo or more access points operating on overlapping channels.
NEW QUESTION # 120
Referring to the exhibit, what is the site ID?
Answer: C
Explanation:
Reference: https://www.mist.com/documentation/find-org-site-id/
According to the exhibit, the site ID is 978c48e6-6ef6-11e6-8bbf-02e208b2d34f. This can be seen from the URL of the site dashboard, which contains the site ID as a parameter.
NEW QUESTION # 121
......
A lot of progress is being made in the Juniper sector today. Many companies offer job opportunities to qualified candidates, but they have specific JN0-452 certification criteria to select qualified candidates. Thus, they can filter out effective and qualified candidates from the population. Mist AI Wireless, Specialist (JNCIS-MistAI-Wireless) (JN0-452) must be taken and passed to become a certified individual.
