How does a Juniper Access Point detect rogue and honeypot APs?
- A. The Juniper Access Point has a radio dedicated only for scanning and detecting rogue and honeypot APs.
- B. The Juniper Access Point uses all of its radios simultaneously to detect rogue and honeypot APs.
- C. The Juniper Access Point uses its radios in round-robin fashion to detect rogue and honeypot APs.
- D. The Juniper Access Point detects rogue and honeypot APs only by communicating with its Layer
2 switch.
Answer: A
Explanation:
Juniper Mist APs include a third, dedicated dual-band (2.4/5 GHz) radio whose sole job is background scanning - spectrum analysis, security monitoring, and detection of rogue and honeypot APs. Because this radio is separate from the two client-serving radios, the AP can continuously scan for threats without interrupting or degrading client traffic.

An organization has standardized its wireless network configuration using a WLAN template and an RF template, which are applied to all sites. An administrator now needs to disable the status LEDs on only the APs located in the executive conference rooms at the headquarters site to avoid visual distractions. What is the most efficient and targeted way to apply this setting without affecting other APs?
- A. Create a new RF template with LEDs disabled and apply it to the entire headquarters site.
- B. Edit the primary WLAN template and add a WxLAN rule to disable LEDs for specific APs.
- C. Create a Device Profile, add only the executive conference room APs to it, and set the "Enable LEDs" option to disabled within the profile.
- D. SSH into each conference room AP and manually issue a command to disable the LED.
Answer: C
NEW QUESTION # 24
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. Optimize the frequency by selecting Optimize Now.
- B. Restart the WLANs.
- C. Restart the clients.
- D. Restart the APs.
Answer: A
Explanation:
After adjusting the RF template, you apply the changes by running Optimize Now, which triggers Mist's radio resource management to reassign channels and power settings. This ensures clients can use the full 5 GHz UNII-2 Extended band without requiring AP or client restarts.
NEW QUESTION # 25
From the Mist Marvis Minis dashboard you notice a failed test. When viewing the current test result, all tests passed except for the Application test. What would be a reason for the failed test?
- A. The DNS lookup has failed.
- B. The switch attached to the AP performing the test has failed.
- C. A firewall rule was implemented blocking the application.
- D. SSID scheduling has disabled a user WLAN.
Answer: C
Explanation:
In Marvis Minis, if all tests (DHCP, ARP, DNS) succeed but the Application test fails, it indicates that connectivity to the application itself is blocked. A common cause is a firewall rule preventing access, while basic network services remain functional.

NEW QUESTION # 28
A client has a poor Wi-Fi experience when moving around in an office. In this scenario, which Marvis Query Language clause would help troubleshoot the problem?
- A. ROAMINGOF
- B. UTILIZATIONOF
- C. RANK
- D. STATUSOF
Answer: A
Explanation:
In the Juniper Mist AI ecosystem, troubleshooting the mobility experience of a user requires analyzing the transitions between Access Points (APs). When a client reports a "poor experience when moving," it almost always points to a breakdown in the roaming process, such as sticky clients (devices that refuse to move to a closer AP), slow handoffs, or authentication failures during a roam. The Marvis Query Language (MQL) provides a conversational and structured way to extract this specific data using the ROAMINGOF clause.
The ROAMINGOF clause is designed to filter the massive amount of telemetry collected by Mist and focus specifically on the events surrounding a client's transition from one radio to another. When you execute a query like "Roaming of [Client Name]," Marvis returns a detailed visualization of the client's journey. This includes the signal strength (RSSI) at the time of the roam, the duration of the handoff, and whether the roam was "successful," "slow," or "failed".
By using this clause, an administrator can quickly identify if the "poor experience" is caused by poor overlap (where RSSI drops too low before a new AP is found) or if the client is holding onto a distant AP (sticky client behavior). Other clauses like STATUSOF (A) are used for general health checks, UTILIZATIONOF (C) tracks radio or site traffic levels, and RANK (D) is typically used to identify the best or worst performing entities (like "Rank APs by interference"). Only ROAMINGOF provides the temporal and spatial correlation needed to fix issues specifically related to user movement within the office environment.

NEW QUESTION # 31
Which real-time location system component takes the coordinates of a tracked device and applies a location- aware triggered action to a client?
- A. Juniper Mist Edge
- B. Marvis Minis
- C. location system
- D. location sensor
Answer: C
Explanation:
In the architecture of aMist AI Real-Time Location System (RTLS), the process of moving from raw signal data to an actionable event involves several distinct layers. To understand why thelocation systemis the correct answer, we must examine how Mist processes Location-Based Services (LBS).
The workflow begins withlocation sensors(typically Mist Access Points). these sensors collect raw Bluetooth Low Energy (BLE) or Wi-Fi signals (RSS measurements) from tracked assets or mobile devices. These raw data points are then transmitted to the cloud-basedMist AI engine. Thelocation system(often referred to as the Location Engine within the Mist Cloud) is the specific functional component responsible for calculating the precise X/Y coordinates of the device using machine learning and trilateration algorithms.
However, its role does not end at mere coordinate calculation. The Mist location system is designed to be
"context-aware." Once the coordinates are established, the system maps these coordinates against defined zones, virtual beacons (vBeacons), or geofencesconfigured in the Mist dashboard. When a device's coordinates intersect with a predefined boundary, the location system triggers alocation-aware action. This could include sending a webhook to a third-party application, pushing a proximity notification to a mobile SDK client, or recording a "visit" in the analytics engine.
WhileJuniper Mist Edgehandles data plane tunneling andMarvis Minisacts as a digital twin for network simulation, they do not manage the coordinate-to-action logic. Thelocation systemis the intelligence that bridges the gap between spatial data and business logic, ensuring that the right client receives the right trigger based on their physical presence within a venue.

NEW QUESTION # 43
All the access points (APs) on the site will obtain an IP address for the Management VLAN. You notice an additional IP address for each configured VLAN on the AP.
Which statement is correct in this scenario?
- A. The AP MAC has a DHCP reservation.
- B. The AP is configured to support wireless mesh.
- C. This behavior is enabled by default under the Site configuration.
- D. The Local Status Page has been enabled in the AP setting under the Site configuration.
Answer: D
Explanation:
According to the Mist documentation1, a Mist AP will pull a management IP address from the Native VLAN by default. However, if the Local Status Page is configured for the Site, all the site APs will pull their own IP address from the Management VLAN, but also addresses for each of the VLANs configured on the AP. This is because each AP creates a Switch Virtual Interface (SVI) for each VLAN on its eth0 interface.
The Local Status Page is a feature that allows you to access information about an AP's status and configuration through a web browser by connecting to its IP address2. This feature can be enabled or disabled at the site level under Site Settings > Access Points > Advanced Settings.
