NEW QUESTION # 118
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?
Answer: A
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.
NEW QUESTION # 119
You want to place specific users into specific VLANs based on user credentials.
Which WLAN feature is needed to accomplish this task?
Answer: B
Explanation:
Dynamic VLAN assignment places users into specific VLANs based on authentication attributes returned for their credentials. This allows the WLAN to assign network access policies per user or group during authentication.
NEW QUESTION # 120
Which real-time location system component takes the coordinates of a tracked device and applies a location- aware triggered action to a client?
Answer: D
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 # 121
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?
Answer: D
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 # 122
Which two 802.11 Physical Layers operate in the 5 GHz frequency band? (Choose two.)
Answer: C,D
Explanation:
802.11a operates only in the 5 GHz band, while 802.11n can operate in both 2.4 GHz and 5 GHz bands using high throughput physical layer capabilities.
