By default, which 6 GHz channels does Juniper Mist radio resource management (RRM) use?
Correct Answer: A
InJuniper Networks Mist AI Wireless, Radio Resource Management (RRM) is designed to optimize RF performance automatically while minimizing client impact. With the introduction ofWi-Fi 6E and the 6 GHz band, Juniper Mist follows industry standards and client behavior to ensure efficient and reliable operation. By default, Mist RRM uses thePreferred Scanning Channels (PSCs)in the 6 GHz spectrum. The 6 GHz band introduces a very large number of available channels, which creates challenges for client discovery, scanning efficiency, and roaming speed. To address this, the IEEE definedPreferred Scanning Channels (PSCs)-a specific subset of 6 GHz channels that access points advertise and clients prioritize during active and passive scanning. These PSCs allow clients to discover networks faster without having to scan the entire 6 GHz channel set. Juniper Mist RRM automatically selects and operates on these PSCs by default to: * Improve client discovery and association times * Reduce unnecessary scanning overhead * Enhance roaming performance * Maintain compatibility across a wide range of Wi-Fi 6E client devices Mist continuously evaluates RF conditions using telemetry and AI-driven analysis, but it intentionally limits default operation to PSCs to balance performance, efficiency, and client interoperability. Administrators can override defaults and customize channel plans if required, but PSCs remain the recommended baseline for most deployments. The incorrect options are explained as follows: * Option Bis incorrect because Mist RRM does not require manual primary channel selection by default. * Option Crefers to 2.4 GHz non-overlapping channels, not 6 GHz. * Option Drepresents the full 6 GHz channel range, which is not practical for default scanning or operation due to client limitations. Therefore, the correct answer isthe preferred scanning channels (PSCs), which Juniper Mist RRM uses by default in the 6 GHz band to ensure optimal Wi-Fi 6E performance.
Question 32
Your Juniper Access Point has changed channels due to RADAR being observed on a DFS channel. This change is an example of which Juniper Mist RRM system?
Correct Answer: D
InJuniper Networks Mist AI Wireless, Radio Resource Management (RRM) uses multiple decision-making systems to adapt the RF environment intelligently. A channel change triggered by the detection ofRADAR on a DFS (Dynamic Frequency Selection) channelis a clear example of anevent-driven RRM action. DFS channels are regulated frequencies that must be shared with weather, military, and aviation radar systems. Regulatory bodies require wireless devices toimmediately vacate a DFS channelwhen radar activity is detected. When a Juniper Mist AP operating on a DFS channel detects radar signatures, it generates areal-time RF event. This event forces the AP to immediately stop transmitting on that channel and move to a new, non-DFS or alternate DFS channel. Mist classifies this behavior asevent-driven RRMbecause: * The channel change isreactive, not predictive * It is triggered by aspecific external RF event(radar detection) * It requiresimmediate actionto maintain regulatory compliance and avoid interference The other options are incorrect for the following reasons: * FCC compliancedefineswhythe change is required, but it is not an RRM system or decision model. * Global optimizationrefers to long-term RF tuning across the network based on historical performance data, not immediate forced changes. * Reinforcement learningis used by Mist to optimize RF parameters over time through continuous learning, not for mandatory, instantaneous responses to radar events. Mist RRM combinesevent-driven actions,AI-based global optimization, andreinforcement learningto deliver both compliance and performance. In the case of radar detection on a DFS channel, the AP's channel change is driven by areal-time RF event, makingevent-driven RRMthe correct answer.
Question 33
For a vBLE-based location service to achieve the highest accuracy, what is the recommended mounting orientation for a Juniper Mist AP?
Correct Answer: B
Question 34
Which Mist AI feature uses machine learning to automatically identify and prioritize network issues affecting the most users?
Correct Answer: A
Marvis Actions proactively analyzes network telemetry and uses machine learning to detect systemic issues, then ranks them by the number of impacted clients or sites, allowing administrators to prioritize remediation efforts effectively.
Question 35
There are two methodologies to troubleshoot client problems utilizing the Marvis VNA. According to Juniper Networks, what are the two methodologies? (Choose two.)
Correct Answer: B,C
Marvis VNA supports proactive troubleshooting by identifying issues before users report them and reactive troubleshooting by helping investigate reported client problems using AI-driven insights and client-level event data.
