NEW QUESTION # 48
Which real-time location system component takes the coordinates of a tracked device and applies a location- aware triggered action to a client?
- A. location sensor
- B. location system
- C. Juniper Mist Edge
- D. Marvis Minis
Answer: B
Explanation:
In the architecture of a Mist AI Real-Time Location System (RTLS), the process of moving from raw signal data to an actionable event involves several distinct layers. To understand why the location system is the correct answer, we must examine how Mist processes Location-Based Services (LBS).
The workflow begins with location sensors (typically Mist Access Points). these sensors collect raw Bluetooth Low Energy (BLE) or Wi-Fi signals (RSS measurements) from tracked assets or mobile devices.
These raw data points are then transmitted to the cloud-based Mist AI engine. The location system (often referred to as the Location Engine within the Mist Cloud) is the specific functional component responsible for calculating the precise X/Y coordinates of the device using machine learning and trilateration algorithms.
However, its role does not end at mere coordinate calculation. The Mist location system is designed to be
"context-aware." Once the coordinates are established, the system maps these coordinates against defined zones, virtual beacons (vBeacons), or geofences configured in the Mist dashboard. When a device's coordinates intersect with a predefined boundary, the location system triggers a location-aware action. This could include sending a webhook to a third-party application, pushing a proximity notification to a mobile SDK client, or recording a "visit" in the analytics engine.
While Juniper Mist Edge handles data plane tunneling and Marvis Minis acts as a digital twin for network simulation, they do not manage the coordinate-to-action logic. The location system is the intelligence that bridges the gap between spatial data and business logic, ensuring that the right client receives the right trigger based on their physical presence within a venue.
NEW QUESTION # 49
You want to review the roaming activity of a specific wireless client. In this scenario, which two Marvis features would you use to accomplish this task? (Choose two.)
- A. Marvis Virtual Network Assistant
- B. Marvis Query Language
- C. Marvis Actions
- D. Marvis Minis
Answer: A,B
Explanation:
To review and troubleshoot the roaming activity of a specific client within a Juniper Mist environment, administrators rely on the conversational and analytical power of the Marvis Virtual Network Assistant (D) and its underlying Marvis Query Language (C). While other Marvis components like Actions focus on organization-wide health and Minis focus on synthetic testing, the VNA and MQL are specifically designed for deep-dive investigations into individual client experiences.
The Marvis Virtual Network Assistant (VNA) serves as the primary interface for this task. It allows an administrator to interact with the Mist AI using natural language. By typing a request such as "Troubleshoot client [Client Name]" or "How was the roaming for [Client Name]?", Marvis VNA aggregates all relevant telemetry data-including signal strength (RSSI), AP transitions, and authentication timings-into a simplified, human-readable summary. It provides a visual timeline of where the client moved and whether each roam was successful, slow, or failed.
Behind the scenes, these natural language requests are often converted into or powered by the Marvis Query Language (MQL). MQL is a structured way to query the Mist Graph API. For specific roaming reviews, the ROAMINGOF clause is used to filter the massive Mist data set for events related only to that client's mobility. For example, a query like roaming of "User-1" during last 24 hours will return a detailed data set showing the "From AP" and "To AP" details, the delta in signal strength during the handoff, and any associated latency.
By using these two features together, administrators can distinguish between a "sticky client" (one that refuses to roam despite a better signal being available) and a "coverage hole" (where the signal drops too low before a new AP is detected). This AI-driven approach eliminates the need for manual packet captures or log parsing, significantly reducing the Mean Time to Repair (MTTR) for mobility-related issues.
NEW QUESTION # 50
Referring to the exhibit, what are two reasons why a Mist AP would have multiple IP addresses? (Choose two.)
- A. One IP address is used for control traffic and one address is used for management traffic.
- B. One IP address is used for redundancy.
- C. The Local Status Page is enabled in the site settings.

NEW QUESTION # 58
Exhibit:
Referring to the exhibit, which client has the weakest connection to the WLAN?
- A. Client 1
- B. Client 3
- C. Client 4
- D. Client 2
Answer: A
Explanation:
InJuniper Networks Mist AI Wireless, the strength and quality of a client's wireless connection are primarily evaluated usingRSSI (Received Signal Strength Indicator)andSNR (Signal-to-Noise Ratio).
These two metrics are core inputs into multiple Wireless Assurance SLEs, including Coverage and Throughput, and are reliable indicators when determining which client has the weakest WLAN connection.
From the exhibit, the key metrics for each client are:
* Client 1: RSSI-81 dBm, SNR11 dB
* Client 2: RSSI -71 dBm, SNR 21 dB
* Client 3: RSSI -67 dBm, SNR 25 dB
* Client 4: RSSI -70 dBm, SNR 22 dB
In wireless design,lower (more negative) RSSI values indicate weaker signal strength, andlower SNR values indicate poorer signal qualitydue to higher relative noise. Among all listed clients,Client 1 clearly has the weakest connection, as it has both:
* Thelowest RSSI(-81 dBm), indicating it is farthest from the AP or experiencing significant attenuation.
* Thelowest SNR(11 dB), which suggests the signal is only marginally stronger than the background noise.
Mist best practices typically consider RSSI values below -70 dBm and SNR values below ~20 dB as suboptimal for reliable performance, especially for higher modulation schemes. Client 1 falls well below these thresholds, making it the most likely to experience low data rates, retransmissions, and degraded user experience.
Mist AI would flag this client as having poor coverage and may recommend actions such as:
* Improving AP placement or density
* Adjusting RF power or channel plans
* Enforcing minimum RSSI thresholds
Therefore, based on both RSSI and SNR,Client 1has the weakest WLAN connection, makingOption Dthe correct answer.

All the access points (APs) on the site will obtain an IP address for the Management VLAN. You notice an additional IP address for each configured VLAN on the AP.
Which statement is correct in this scenario?
- A. The AP is configured to support wireless mesh.
- B. This behavior is enabled by default under the Site configuration.
- C. The AP MAC has a DHCP reservation.
- D. The Local Status Page has been enabled in the AP setting under the Site configuration.
Answer: D
Explanation:
According to the Mist documentation1, a Mist AP will pull a management IP address from the Native VLAN by default. However, if the Local Status Page is configured for the Site, all the site APs will pull their own IP address from the Management VLAN, but also addresses for each of the VLANs configured on the AP. This is because each AP creates a Switch Virtual Interface (SVI) for each VLAN on its eth0 interface.
The Local Status Page is a feature that allows you to access information about an AP's status and configuration through a web browser by connecting to its IP address2. This feature can be enabled or disabled at the site level under Site Settings > Access Points > Advanced Settings.
