質問 # 32
The Mist Site Insights Dashboard helps network administrators in which two ways? (Choose two.)
正解：A、C
質問 # 33
Which two wired elements would be configured using an organization-level template? (Choose two.)
正解：A、D
解説：
Two wired elements configured using an organization-level template in Juniper Mist are VLAN and DNS settings. Organization-level templates are designed to standardize and propagate common settings across all switches within an organization. As per official guides: "These templates can include VLANs and well-known services such as DNS (Domain Name System) that can be used across all devices within a site." VLAN and DNS settings are defined once at the organization (or switch group) template and automatically inherited by all devices, ensuring consistency. Host name and role are set at an individual switch level, not globally via templates.

質問 # 34
Which statement accurately describes the capabilities of the Juniper Mist AI platform?
正解：D
解説：
TheJuniper Mist AI platformis acloud-native, AI-driven network management solutionthat leverages machine learning and data science to provide predictive insights, proactive troubleshooting, and automated optimization acrosswireless, wired, and WANenvironments.
At the core of this intelligence is thePredictive Analytics and Correlation Engine (PACE), which powers Mist AI's ability to process and analyze massive volumes of telemetry data in near real time.
According to theJuniper Mist AI Cloud Architecture Guide,
"The Predictive Analytics and Correlation Engine (PACE) collects, correlates, and analyzes pre-connection and post-connection user experience data, enabling real-time visibility and proactive detection of network anomalies." This allows Mist AI to perform the following:
* Understand client onboarding and connectivity performance through SLE (Service Level Expectation) metrics.
* Detect anomalies automatically and identify root causes with Marvis.
* Continuously learn and improve via theMist AI efficacy loop.
OptionsA,C, andDare incorrect because:
* Mist AI is fully automated and does not rely on manual data collection.
* The Mist Cloud is the central data aggregation and analysis engine.
* Marvisis proactive and autonomous, not dependent on user-driven troubleshooting.
Therefore, the correct answer isB. Juniper Mist AI uses Predictive Analytics and Correlation Engine (PACE) to collect and analyze pre-connection and post-connection user and location states in near real- time.

質問 # 35
Which statement is true about wireless security?
正解：C
解説：
The correct statement is that Juniper APs have a dedicated radio to scan for rogue and honeypot APs. The official Juniper Mist documentation specifies: "Juniper APs include a dedicated scanning radio to detect rogue, neighbor, and honeypot APs and their clients... The dedicated scanning radios operate on 2.4, 5, and 6 GHz Wi-Fi bands." This third radio operates independently from the client-serving radios and enables continuous threat detection on all Wi-Fi bands, enhancing security and allowing real-time performance adjustments. BLE radios are used for location-based services and asset tracking, not for rogue AP detection.
Client-serving radios can also scan, but detection is always enabled and optimized by the dedicated radio.

質問 # 36
With which two external directory services does Juniper Mist Access Assurance integrate?
(Choose two.)
正解：A、B
解説：
Juniper Mist Access Assurance integrates with Microsoft Azure Active Directory for user authentication and policy enforcement.
It also integrates with Okta Workforce Identity to provide secure access control and identity management.
