NEW QUESTION # 55
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. 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
- B. A Juniper AP will maintain its configuration by default once rebooted regardless of an Internet connection or not.
- 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 # 56
A customer is replacing their previous WLAN controller with a Mist Edge to maintain centralization of user traffic.
How does Mist Edge affect control plane forwarding and data plane forwarding in this scenario?
- A. Control plane forwarding applies to the Mist Cloud and data plane forwarding applies to the Mist Cloud.
- B. Control plane forwarding applies to the Mist Edge and data plane forwarding applies to the Mist Edge.
- C. Control plane forwarding applies to the Mist Edge and data plane forwarding applies to the Mist Cloud.
- D. Control plane forwarding applies to the Mist Cloud and data plane forwarding applies to the Mist Edge.
Answer: D
Explanation:
When a customer replaces their previous WLAN controller with a Mist Edge in order to maintain centralization of user traffic, control plane forwarding applies to the Mist Cloud while data plane forwarding applies to the Mist Edge. So the correct answer is A. Control plane forwarding applies to the Mist Cloud and data plane forwarding applies to the Mist Edge.

- E. The DHCP server has exhausted its pool of available IP addresses.
Answer: D,E
NEW QUESTION # 58
A malicious user tricks users by broadcasting the same SSID that matches the legitimate AP in your corporate network. How does Juniper Mist classify this type of AP?
- A. honeypot AP
- B. neighbor AP
- C. rogue AP
- D. mesh AP
Answer: A
Explanation:
In the context of Juniper Mist WxLAN Security and Rogue AP detection, Mist AI categorizes surrounding access points into specific buckets based on their behavior and their connection to the local network infrastructure. Understanding the distinction between a Rogue AP and a Honeypot AP is essential for proper security posture.
A Honeypot AP (C) is specifically defined as an unauthorized access point that is broadcasting one of your organization's protected SSIDs (or a very similar one) but is not physically connected to your wired network.
This is a classic "Evil Twin" attack where a malicious actor attempts to trick corporate users into connecting to a fake signal. Because the clients' devices are often programmed to auto-associate with known SSIDs, they may unknowingly connect to the Honeypot AP, allowing the attacker to intercept traffic, perform man-in-the- middle attacks, or harvest credentials. Mist APs use their dedicated scanning radio (found in the AP43, AP45, and similar models) to constantly monitor the airwaves for these spoofed SSIDs.
In contrast, a Rogue AP (D) is an unauthorized AP that is physically connected to your corporate wired network (LAN). Mist identifies these by correlating the MAC addresses seen on the air with those seen on the wired switch ports. A Neighbor AP (B) is simply an AP from a nearby business that is broadcasting its own unique SSID and is not connected to your network; these are ignored by security alerts.
By classifying the threat as a Honeypot, Mist AI informs the administrator that the threat is external to the wired infrastructure but poses a direct risk to client data. Mist can even be configured to take automated action, such as sending de-authentication frames to prevent clients from successfully staying connected to the malicious Honeypot AP.
NEW QUESTION # 59
You are deploying multiple Mist APs across many sites in your network. You must ensure that you can group similar devices together to easily apply consistent WxLAN policies across multiple sites.

- A. radio management
- B. device profile
- C. organization labels
- D. RF template
Answer: B
Explanation:
When deploying multiple Mist APs across many sites in your network and grouping similar devices together to easily apply consistent WxLAN policies across multiple sites, you should use device profiles.
NEW QUESTION # 60
Asset tracking using Mist-supported third-party BLE beacons has been installed in a warehouse. The BLE beacons were configured using their manufacturer-supplied configuration utility and BLE was properly configured for the site settings. When the warehouse floor plan is opened in Live View, the third-party beacons are not shown.
Which two statements describe causes for this issue? (Choose two.)
- A. The Locate this Client as an Asset check box has not been selected at the BLE client level.
- B. The Show assets check box has not been selected in Live View.
- C. Marvis was not enabled for the site.
- D. The APs are installed at 19 feet from the floor, above the recommended 15 feet.
Answer: A,B
Explanation:
According to the Mist documentation1, asset tracking is a service that allows you to find key assets and people with detailed analytics based on their location using Mist-supported third-party BLE beacons. To enable asset tracking, you need to configure both the BLE beacons and the Mist cloud settings.
The Show assets check box is a setting in Live View that allows you to display or hide the assets on the floor plan2. If this check box is not selected, you will not be able to see the third-party beacons on Live View.
The Locate this Client as an Asset check box is a setting at the BLE client level that allows you to treat a BLE client as an asset for location purposes3. If this check box is not selected, you will not be able to track the BLE client as an asset.

NEW QUESTION # 63
You want to review the roaming activity of a specific wireless client. In this scenario, which two Marvis features would you use to accomplish this task? (Choose two.)
- A. Marvis Query Language
- B. Marvis Virtual Network Assistant
- C. Marvis Actions
- D. Marvis Minis
Answer: A,B
Explanation:
To review and troubleshoot the roaming activity of a specific client within a Juniper Mist environment, administrators rely on the conversational and analytical power of the Marvis Virtual Network Assistant (D) and its underlying Marvis Query Language (C). While other Marvis components like Actions focus on organization-wide health and Minis focus on synthetic testing, the VNA and MQL are specifically designed for deep-dive investigations into individual client experiences.
The Marvis Virtual Network Assistant (VNA) serves as the primary interface for this task. It allows an administrator to interact with the Mist AI using natural language. By typing a request such as "Troubleshoot client [Client Name]" or "How was the roaming for [Client Name]?", Marvis VNA aggregates all relevant telemetry data-including signal strength (RSSI), AP transitions, and authentication timings-into a simplified, human-readable summary. It provides a visual timeline of where the client moved and whether each roam was successful, slow, or failed.
Behind the scenes, these natural language requests are often converted into or powered by the Marvis Query Language (MQL). MQL is a structured way to query the Mist Graph API. For specific roaming reviews, the ROAMINGOF clause is used to filter the massive Mist data set for events related only to that client's mobility. For example, a query like roaming of "User-1" during last 24 hours will return a detailed data set showing the "From AP" and "To AP" details, the delta in signal strength during the handoff, and any associated latency.
By using these two features together, administrators can distinguish between a "sticky client" (one that refuses to roam despite a better signal being available) and a "coverage hole" (where the signal drops too low before a new AP is detected). This AI-driven approach eliminates the need for manual packet captures or log parsing, significantly reducing the Mean Time to Repair (MTTR) for mobility-related issues.
NEW QUESTION # 64

NEW QUESTION # 66
Which two statements correctly describe the Wi-Fi location component of Juniper Mist's location-based services? (Choose two.)
- A. It is included in the Wireless Assurance subscription.
- B. It requires the Asset Visibility subscription.
- C. It tracks third-party BLE tags.
- D. It is enabled by default.
Answer: A,B
Explanation:
Juniper Mist separates its Location-Based Services (LBS) into distinct functional areas: User Engagement (vBLE-based) and Asset Visibility (tracking assets via Wi-Fi or BLE). Understanding the licensing and default behavior is crucial for a successful deployment.
The Wi-Fi location component is designed to track devices that are connected to the Wi-Fi network or are simply probing (unconnected). While basic connectivity data is part of the standard management, the high- fidelity tracking of these devices on a map as "assets" or "clients" for location analytics is tied to specific licensing tiers.
First, Wireless Assurance (B) provides the foundational telemetry and data collection required for basic location visibility. However, to unlock the full "Asset Tracking" capabilities-where the system actively correlates coordinates and provides historical data for specific Wi-Fi devices-the Asset Visibility subscription (D) is required. This subscription is what enables the Mist Cloud to process and store the location data for tags and Wi-Fi clients beyond simple real-time display.
Regarding the other options: Statement A is incorrect because the Wi-Fi location component tracks Wi-Fi devices; tracking BLE tags (third-party or otherwise) falls under the BLE/vBLE location component.
Statement C is incorrect because location services are typically not enabled by default to protect user privacy and optimize performance. An administrator must manually upload a floor plan, scale it, and enable
"Wi-Fi Engagement" or "Asset Tracking" within the Site settings or individual Access Point configurations to begin collecting location data. Once enabled and properly licensed, the Mist AI engine uses RSSI data from multiple APs to provide location coordinates for any Wi-Fi-emitting device in the environment.
NEW QUESTION # 67
