NEW QUESTION # 105
In a Mist vBLE array, what is the function of the single AP that is dynamically elected as the
"beam transmitter"?
Answer: B
NEW QUESTION # 106
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?
Answer: D
Explanation:
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.
NEW QUESTION # 107
Which two SLE classifiers would indicate that a client is having a good roaming experience?
(Choose two.)
Answer: B,C
NEW QUESTION # 108
Exhibit:
Your colleagues report that they are unable to browse tutorials needed for work located at youtube.com when using their BYOD devices. When using a guest device, they are able to access youtube.com.
In this scenario, how would you allow BYOD colleagues to access youtube.com using the WxLAN policies?
Answer: C
Explanation:
InJuniper Networks Mist AI Wireless,WxLAN policiesare evaluated using atop-down, first-match logic.
This means that when traffic matches a policy condition, that policy is applied immediately, andno further policies are evaluated. Understanding this evaluation order is critical when troubleshooting access discrepancies between user types such as BYOD and guest users.
From the scenario and the exhibit, guest devices are able to accessyoutube.com, while BYOD devices are blocked. This indicates that:
* Theguest WxLAN policyallows "All Video and Music" traffic (which includes YouTube).
* TheBYOD WxLAN policyblocks "All Video and Music" traffic.
* The BYOD policy is evaluatedbeforethe guest policy.
Because BYOD users are matched to the BYOD label, their traffic hits the BYOD policy first and is denied before it can reach the more permissive guest policy. Simply modifying labels or deleting policies is unnecessary and could introduce unintended access control issues.
The correct and least disruptive solution is tomove the BYOD WxLAN policy above the guest policyand then adjust the BYOD policy rules (for example, allowing YouTube or the "All Video and Music" category).
By reordering the policies, you ensure that BYOD traffic is evaluated correctly and receives the intended permissions without impacting guest access.
The incorrect options are explained as follows:
* Deleting policies(Options A and C) is not best practice and risks breaking segmentation and access control.
* Option Bis irrelevant, as the contractor policy does not affect BYOD or guest traffic in this scenario.
Therefore, the correct solution is tomove the WxLAN policy for BYOD above the policy for guests, making Option Dthe correct answer.
NEW QUESTION # 109
Which statement is true about passive scanning for access point (AP) discovery?
Answer: C
Explanation:
In 802.11 wireless networking and the Juniper Mist ecosystem, Passive Scanning is one of the two primary methods a client station (STA) uses to discover available wireless networks.4 In this mode, the client radio does not transmit any data to find an Access Point. Instead, it "waits and listens" on each supported channel for a specific period of time to hear Beacon Frames.5 Beacons are management frames sent periodically by an AP (typically every 100ms) to announce the presence and capabilities of a Basic Service Set (BSS).6 These frames contain critical information such as the SSID (Network Name), supported data rates, security protocols (RSN), and PHY requirements.7 Because the client only needs to keep its receiver active and does not have to power up its transmitter to send probe requests, passive scanning is significantly more power-efficient than active scanning, making it ideal for battery- constrained IoT devices.
However, the trade-off for this power efficiency is time. Since a client must stay on each channel long enough to guarantee it hears a beacon (at least one full beacon interval), scanning the entire 2.4 GHz, 5 GHz, and 6 GHz spectrum can take several seconds. In contrast, Active Scanning (options B, C, and D) involves the client sending Probe Requests (either wildcard/null or directed to a specific SSID) and waiting for a much shorter period for a Probe Response.8 From a Mist AI perspective, the dedicated scanning radio in Mist APs (like the AP43/AP45) performs its own version of passive and active scanning to build a complete map of the RF environment. This data is used by Marvis to detect "Neighbor" and "Honeypot" APs. While most modern mobile clients prefer active scanning to speed up the discovery and roaming process, passive scanning remains a fundamental requirement- especially on DFS channels where regulatory rules prohibit a client from transmitting until it has first
"listened" to confirm no radar is present.
