JN0-452 Exam Dumps - Juniper JNCIS-MistAI Questions and Answers

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 WLANs with SSIDs NETGEAR24 and Bob24WiFi will cause adjacent channel interference because they are using overlapping channels in the 2.4 GHz frequency band.

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.

If Bluetooth-only mobile client devices with an SDK-enabled app do not appear in the Mist GUI under Clients/App Clients even though they have Bluetooth enabled, it could be because the AP BLE radios do not hear the SDK-enabled client’s BLE beacons.

According to the Mist documentation1, Mist SDK is a software development kit that enables indoor location and proximity services using Mist’s virtual Bluetooth LE (vBLE) technology. The SDK allows mobile applications to communicate with Mist APs using BLE beacons that are transmitted by the client devices.

The devices with the SDK-enabled app have Bluetooth enabled, but they do not appear in the Mist GUI under Clients/App Clients because the AP BLE radios do not hear the SDK-enabled client’s BLE beacons. This could be due to various factors such as interference, distance, obstacles, or configuration issues that affect the BLE signal strength and quality.

According to the VLANs (Static & Dynamic) - Mist document3, you can define VLANs as untagged, tagged, or using VLAN pooling in the WLAN settings in the Juniper Mist UI. A WLAN is a wireless network that defines parameters such as SSID, security type, and VLAN.

The 37% of Successful Connects suggest that 63% failed – however, these are spread between both LD_Testbed_MD and LD_RS_Support. If the only AP with connection issues was LD_RS_Support then the reverse math may have worked.

According to the Webhooks - Mist document, two types of information that would be streamed through webhooks are:

Alerts, which are notifications that are triggered by certain events or conditions on the network.

SLE metrics of clients, which are service level expectations that measure the quality of experience for clients on various aspects such as connection, coverage, capacity, throughput, and roaming.

In the Juniper Mist AI ecosystem, Zone Analytics is the specific real-time location service component designed to provide deep business intelligence regarding how users and devices interact with a physical space. While the Mist platform offers various location services—such as Wayfinding for turn-by-turn navigation and Asset Tracking for locating specific tagged equipment—Zone Analytics focuses on the aggregate behavior of clients within defined boundaries on a floor plan.

Zone Analytics allows administrators to define virtual areas, known as zones, on their facility maps. The Mist Location Engine then uses its patented virtual Bluetooth Low Energy (vBLE) antenna array and machine learning algorithms to track the presence of mobile devices (via the Mist SDK) and Wi-Fi clients within these zones. This service calculates two primary metrics required by the scenario:

Dwell Time: This measures the duration a specific client remains within a defined zone. Administrators can set minimum and maximum dwell thresholds to categorize visitors (e.g., "passersby" vs. "engaged customers").

Movement Patterns: By analyzing transitions between different zones, the service generates "motion flows" or "visitor journey" maps. This helps organizations identify common paths taken through a building, popular entry/exit points, and areas of high congestion.

These insights are typically presented through the Engagement Analytics or Premium Analytics dashboards. For example, a retailer might use Zone Analytics to determine if a new product display is successfully increasing the "dwell time" of shoppers in a specific aisle, or an office manager might use it to optimize "workflow" by seeing how employees move between different departments. By leveraging these real-time data sets, businesses can make informed decisions about staffing, floor layouts, and resource allocation based on actual user behavior patterns.

According to the Virtual Network Assistant | Juniper Networks US document2, Time to Connect is a Wireless Assurance SLE that has classifiers of Association, Authorization, DHCP, and Internet Services. This SLE measures how long it takes for a client device to connect to the network and access internet services.

In the Juniper Mist AI product portfolio, the BT11 is a specialized, enterprise-grade access point designed exclusively for Bluetooth Low Energy (BLE).4 Unlike the other access points in the Juniper Mist family (such as the AP12, AP24, and AP34), the BT11 does not contain Wi-Fi radios.5 Its sole purpose is to provide high-accuracy, enterprise-grade location-based services (LBS) by leveraging Juniper's patented 16-element virtual BLE (vBLE) antenna array.6

The primary use case for the BT11 is to augment BLE coverage in environments where Wi-Fi connectivity is already established by other APs, but the density of those APs is insufficient for precise location services. For applications like turn-by-turn wayfinding or asset tracking, the RF requirements for BLE are often more stringent than those for Wi-Fi. A facility might have enough Wi-Fi APs to provide data coverage, but may have "location holes" where the BLE signals are too sparse for 1–3 meter accuracy. By deploying BT11 units in these gaps, administrators can extend the reach of the location engine without the expense of adding full-featured Wi-Fi radios where additional capacity is not needed.7

The BT11 communicates directly with the Mist Cloud to manage virtual beacons, which eliminate the need for physical, battery-powered beacons and manual calibration.8 Because it runs on Power over Ethernet (PoE) and integrates seamlessly with the Mist AI engine, it provides a scalable and cost-effective way to ensure continuous, high-fidelity BLE coverage across a campus, hospital, or retail floor.
