Pass the Juniper JNCIS-MistAI JN0-452 Questions and answers with Dumpstech

When using location-based services (LBS) at a new warehouse and placing APs on the floor plan with correct scale while ensuring correct location accuracy in this scenario where APs are mounted on trusses 14 feet (4.3 meters) from floor, two actions that should be taken are installing Virtual Beacons in each aisle and configuring height of each AP. So the correct answers are A. Install Virtual Beacons in each aisle and B. Configure height of each AP.

The Compatible WLAN data rate setting is required for legacy 2.4 GHz scanners to connect to the WLAN.

According to the Data Rates - Mist document4, the WLAN data rate setting that is required for legacy 2.4 GHz scanners to connect to the WLAN is Compatible. This setting enables all data rates from 1 Mbps to 54 Mbps for both 2.4 GHz and 5 GHz bands. This setting is recommended for legacy devices that need low data rates to connect.

According to the Wi-Fi configuration with Mist Systems | HCD Consulting GmbH document, three available rate limiting options in the Mist UI are:

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, an extended service set (ESS) is a group of basic service sets (BSSs) that share a common SSID and are connected by a distribution system (DS). Each BSS within the ESS has its own unique BSSID, which is the MAC address of the AP.

Channel bonding combines two adjacent channels to create a wider channel, effectively doubling the available bandwidth. However, this also doubles the required device resources such as power and processing.

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, channel bonding is a technique that combines two adjacent channels into one wider channel to increase throughput. This doubles the available bandwidth but also doubles the required device resources such as power and processing.

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.

The Wireless Assurance SLE that provides information on whether a user is able to associate to the WLAN is Successful Connect. So the correct answer is A. Successful Connect.

According to the Location - how it works - Mist document1, a Mist AP actually begins transmitting BLE when it is placed on a floor plan. This is because the Mist cloud uses the floor plan information to calculate the optimal BLE transmission pattern for each AP.

According to the exhibit, the WLAN has a minimum basic rate of 24 Mbps for both 2.4 GHz and 5 GHz bands. This corresponds to the high-density data rate setting in Mist, which disables all data rates below 24 Mbps. This setting is recommended for high density designs, where clients have enough signal strength and quality to operate at higher rates.
