NEW QUESTION # 37
Which two statements are correct about Juniper Mist Dynamic Packet Capture? (Choose two.)

• A. It is automatically attached to the Affected Items list in the Successful Connects SLE.
• B. It is automatically attached to a client event displayed on the Insights page.
• C. It must be globally configured at the organization level.
• D. No configuration is necessary for Mist's Dynamic Packet Capture.

Answer: B,D

NEW QUESTION # 38
Refer to Exhibit:

You notice that your site events show an unresponsive DHCP server in your network. You want to analyze the event by using the dynamic packet capture.
Referring to the exhibit, how would you access the packet capture for further analysis in Wireshark?

• A. Verify the impacted site and use the corresponding site event to fetch the automatically generated packet capture.
• B. Verify the impacted client and use the corresponding site event to fetch the automatically generated packet capture.
• C. Verify the impacted site and use the corresponding organization event to fetch the automatically generated packet capture.
• D. Verify the impacted client and use the corresponding client event to fetch the automatically generated packet capture.

Answer: A

Explanation:
InJuniper Networks Mist AI Wireless,dynamic packet capture (dPCAP)is tightly integrated with events to enable rapid, context-aware troubleshooting. When Mist detects a systemic issue-such as aDHCP server becoming unresponsive-it automatically generates asite-level eventbecause the problem impacts multiple devices within a site rather than a single client.
As shown in the exhibit, the event "DHCP is Unresponsive" lists multiple impacted devices and includes a timeline of contributing network events. This classification is critical: DHCP infrastructure failures are treated assite events, not client-specific or organization-wide events. When such a site event is triggered, Mist can automatically perform adynamic packet captureon the relevant access points to capture DHCP Discover, Offer, Request, and Acknowledgment (DORA) traffic in real time.
To access this packet capture, an administrator must:
* Navigate to theimpacted siteidentified in the event.
* Open thecorresponding site event(in this case, the DHCP unresponsive event).
* Download theautomatically generated packet capture file, which can then be opened inWireshark for detailed protocol-level analysis.
The incorrect options are explained as follows:
* Organization eventsprovide high-level visibility and auditing but do not host packet captures.
* Client eventsare used when a single client experiences issues; they are not appropriate when multiple devices are impacted by a shared service failure.
* Verifying an impacted client does not expose the dynamic packet capture tied to a site-wide DHCP issue.
Therefore, the correct method is toverify the impacted site and use the corresponding site event to fetch the automatically generated packet capture, makingOption Bthe correct answer.

NEW QUESTION # 39
According to Juniper Networks, it is recommended that devices using Mist location-based services (LBS) have line-of-sight to how many APs?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: A

Explanation:
InJuniper Networks Mist AI Wireless, accurate location-based services (LBS) depend heavily on proper RF design and access point density. Juniper recommends that devices participating in Mist LBS maintainline-of- sight (LoS) to at least three access pointsto achieve reliable and consistent location accuracy.
Mist location services use advanced techniques such asRSSI triangulation,virtual BLE (vBLE), andAI- driven probability surface modelingto calculate a device's position. These algorithms require multiple independent signal measurements to accurately determine a device's X,Y coordinates. With signals received fromthree or more APs, Mist can triangulate the device position effectively and minimize errors caused by multipath reflections, attenuation, or transient RF noise.
If a device has line-of-sight to only one or two APs, the system lacks sufficient spatial diversity to calculate a precise location. This can result in ambiguous positioning, reduced accuracy, or excessive location "drift." While additional APs (four or more) can further improve accuracy and stability-especially in high-value use cases such as asset tracking or wayfinding-three APs is the recommended minimum baselinefor dependable LBS performance.
Mist's AI continuously evaluates signal quality, AP geometry, and environmental factors to refine location estimates, but it cannot compensate for insufficient AP visibility. As a result, Juniper best practices for LBS design emphasize:
* Proper AP placement and height
* Adequate AP density
* Ensuring devices can "see" at least three APs at all times
The other options are incorrect because:
* One or two APsdo not provide enough data for reliable triangulation.
* Four APsmay improve accuracy but are not the minimum recommendation.
Therefore, the correct answer isB. 3.

NEW QUESTION # 40
RF templates are assigned to which Mist configuration object?

• A. WLANs

NEW QUESTION # 42
You are asked to perform a site survey on your enterprise by using a Juniper Access Point (AP) that is fully functional and visible by the Juniper Mist cloud. Your enterprise provides you with the portable equipment for elevating the Juniper AP and a battery that properly powers it. In this scenario, how would you ensure that the Juniper AP will be fully functional for site survey purposes?

• A. A Juniper AP will maintain its configuration by default once rebooted regardless of an Internet connection or not.
• B. You will need to enable Site Survey Mode in the site configuration to force the Juniper AP to remember its configuration regardless of an Internet connection or not.2
• C. A Juniper AP will maintain its configuration by default as long as the Wi-Fi Assurance license has not expired.
• D. You will need to enable AP Config Persistence and disable AP Uplink Monitoring in the site configuration to force the Juniper AP to remember its configuration regardless of an Internet connection or not.1

Answer: D

Explanation:
In a traditional deployment, aJuniper Mist Access Pointis a "cloud-first" device, meaning it expects a constant connection to the Mist Cloud to receive configuration updates and report telemetry. When performing an "AP-on-a-Stick" (APoS) site survey, the AP is often powered by a battery pack and moved to various locations where an active Ethernet backhaul or Internet connection is unavailable.3To ensure the AP continues to broadcast the required SSIDs for signal measurement in this "disconnected" state, two specific settings must be adjusted within the Mist dashboard.
First,AP Config Persistencemust be enabled. By default, Mist APs store their configuration in volatile memory; if an AP reboots (which happens when switching battery packs or moving locations) and cannot reach the Mist Cloud, it may fail to reload its previous configuration. Enabling Config Persistence ensures that the AP writes its current configuration to non-volatile flash memory, allowing it to boot up and start broadcasting the programmed SSIDs even in the absence of a cloud connection.4 Second,AP Uplink Monitoringmust be disabled. Mist APs are designed with a safety mechanism where, if the AP loses its gateway connectivity (eth0 link or ping to the gateway), it will stop broadcasting SSIDs to prevent "black-holing" client traffic. In a site survey scenario, the Ethernet port is typically connected only to a battery or a passive PoE injector with no data path.5If Uplink Monitoring remains active, the AP will detect the lack of a backhaul and disable its radios, making the survey impossible. By disabling this feature, the AP is forced to keep its radios active regardless of the uplink status. Together, these two settings allow the AP to function as a standalone signal source, which is essential for accurate RF environment mapping and pre- deployment validation using Mist AI hardware.

NEW QUESTION # 53
You discover that some clients do not use all channels in the 5 GHz UNII-2 Extended frequency band and you have made the appropriate adjustments in the RF template. How do you implement these changes?

• A. Restart the APs.
• B. Optimize the frequency by selecting Optimize Now.
• C. Restart the clients.
• D. Restart the WLANs.

Answer: B

Explanation:
In a Juniper Mist environment, the Radio Resource Management (RRM) system is responsible for the automated allocation of channels and transmit power across all Access Points (APs) at a site. When you modify an RF Template-for example, by excluding specific UNII-2 Extended channels that certain legacy or region-specific clients cannot "see" or support-you are updating the intended policy for the network.
However, because Mist RRM is designed for stability, it does not always force an immediate, disruptive channel change across the entire site the moment a template is saved.
To force the Mist AI engine to immediately recalculate the channel plan based on your new constraints and push those settings to the APs, you use the Optimize Now button. This feature is found within the Radio Management section of the site settings or the RF template application page. When "Optimize Now" is triggered, the Mist Cloud analyzes the current RF environment, takes your new channel exclusions into account, and issues a command to the APs to switch to the most efficient channels available within the newly defined subset.
Choosing Restart the APs (C) or Restart the WLANs (B) is unnecessary and causes more downtime than required. A reboot might eventually result in a new channel selection, but it does not guarantee that the RRM algorithm has fully processed the global optimization for the site. Restarting clients (D) does nothing to change the AP's channel behavior. By using Optimize Now (A), you ensure a coordinated, AI-driven transition that minimizes "co-channel interference" while respecting the updated frequency constraints you defined to accommodate your specific client devices. This ensures that clients previously struggling with unsupported UNII-2 channels are immediately moved to compatible frequencies.
