Juniper Mist AI, Associate (JNCIA-MistAI) 認定 JN0-253 試験問題 (Q136-Q141):

質問 # 136
You are asked to create a real-time visualization dashboard which displays clients on a map.
Which two Juniper Mist functions would you use in this scenario? (Choose two.)

正解：B、D

解説：
When developing areal-time visualization dashboardthat displays client locations on a map, Juniper Mist offers specific APIs and data streaming methods to support dynamic updates.
According to the Juniper Mist Developer Documentation, theWebSocketinterface enables continuous,real- time streaming of client location and telemetry datadirectly from the Mist Cloud. This mechanism is ideal for live dashboards, as it eliminates the need for repeated REST API polling. WebSocket connections provide instant updates whenever a device moves, connects, or disconnects, ensuring the displayed map remains accurate in real time.
TheLive Viewfeature complements this functionality within the Mist Cloud and third-party integrations. It allows administrators and developers toview live location movements of Wi-Fi clients, BLE beacons, and IoT deviceswithin a site's floor plan. It uses telemetry directly from access points, offering second-by-second updates.
In contrast,RESTful APIsandWebhooksare designed for event-based automation and configuration management rather than live visualization. REST APIs are best for historical or static data retrieval, while Webhooks are used for triggering external actions based on events.
Therefore, the correct functions for real-time map visualization are:
* WebSocket (C)- for continuous live data streaming
* Live View (D)- for direct map-based visualization of client activity

質問 # 137
Which two statements are correct about Juniper Mist's support for BLE (Bluetooth Low Energy)?

正解：A、B


質問 # 138
Which machine learning method uses unlabeled data sets?

正解：B

解説：
InJuniper Mist AI, variousmachine learning (ML)techniques are applied across the platform to analyze network telemetry and improve performance insights. Among these,unsupervised learningplays a critical role in identifying patterns, trends, and anomalies in unlabeled datasets-data that has not been pre-classified or annotated.
According to theJuniper Mist AI and Machine Learning Overview:
"Unsupervised learning enables Mist AI to automatically detect abnormal patterns or clusters in large volumes of unlabeled network data, allowing the system to identify anomalies and optimize network behavior without human labeling." This method allows Mist AI to autonomously recognize deviations in user experience, traffic behavior, or radio performance without prior definitions, helping to enhance predictive analytics and anomaly detection.
By contrast:
* Supervised learningrequires labeled training data.
* Reinforcement learninglearns through trial-and-error feedback loops.
* Cognitive learningis not a formal ML category-it refers to human-inspired reasoning.
Therefore, the correct answer isD. Unsupervised learning.

質問 # 139
Which two protocols does Marvis Minis automatically validate? (Choose two.)

正解：A、C

解説：
Marvis Minisis a feature withinMarvis Virtual Network Assistant (VNA)that proactively tests and validates network performance by simulating user connections. Instead of waiting for user complaints, it performssynthetic client transactionsto confirm the functionality of critical network services.
According to theJuniper Mist Marvis Minis Technical OverviewandMarvis AI Operations Guide, Minis validates several network functions automatically, including:
* Dynamic Host Configuration Protocol (DHCP):Ensures clients can obtain IP addresses properly from DHCP servers, validating end-to-end DHCP exchange success and response time.
* Address Resolution Protocol (ARP):Verifies correct IP-to-MAC address resolution, confirming that clients can reach devices on the same subnet and that ARP tables are updated correctly.
Marvis Minis also performs checks onDNS resolution, authentication, and application reachability, but not on SNMP or NTP. Those protocols are used for management and time synchronization, not end-user connectivity validation.
Thus, the correct answers areB (DHCP)andD (ARP).

質問 # 140
Which two wired elements would be configured using an organization-level template? (Choose two.)

正解：A、B

解説：
VLANs can be defined in an organization-level switch template to ensure consistent network segmentation across sites.
Roles are assigned in the template to apply consistent configurations and policies to switches at scale.
