NEW QUESTION # 145
Which two statements are correct about the Juniper Mist vBLE Asset Visibility mode? (Choose two.)
Answer: C,D
Explanation:
Juniper Mist'svirtual Bluetooth Low Energy (vBLE)technology is designed to deliverprecise indoor location servicesusing cloud-managed access points equipped with integrated BLE antenna arrays. The system supports multiple operational modes, includingEngagement Mode(for mobile app interactions) and Asset Visibility Mode(for BLE tag tracking).
According to theJuniper Mist Location Services Documentation, inAsset Visibility Mode, the vBLE antenna functions primarily inreceive modeto detect and process signals emitted fromBLE asset tags. These tags periodically transmit Bluetooth "chirps" that are received by multiple APs. Mist Cloud then usesangle-of- arrival (AoA)andRSSI triangulation algorithmsto determine the exact location of the asset within the facility.
The documentation specifies:
"In Asset Visibility Mode, the vBLE antenna operates in receive mode and listens for BLE tag beacons (chirps). The system triangulates these signals to calculate the real-time location of tracked assets." Conversely,Engagement Modeis the configuration in which vBLE operates intransmit modeto interact with mobile devices running the Mist SDK - which corresponds to location-based engagement or proximity notifications.
Thus, the correct answers are:
* A. The vBLE antenna is in the receive mode
* B. The vBLE antenna tracks chirps from BLE tags

NEW QUESTION # 146
At which two configuration levels are WLAN objects created? (Choose two.)
Answer: A,B
Explanation:
Site Level: WLAN objects can be created at the site level, allowing specific configurations for different locations within an organization. This helps in customizing WLAN settings based on the unique requirements of each site.
Org Level: WLAN objects can also be created at the organization level, which provides a standardized configuration that can be applied across multiple sites. This ensures consistency in WLAN settings throughout the entire organization.
NEW QUESTION # 147
Under which category would you identify bad cables using Marvis Actions?
Answer: D
Explanation:
Bad cables are identified under the Layer 1 category within Marvis Actions. Juniper Mist's documentation states: "Use the Actions dashboard to resolve Layer 1 issues. When you click the Layer 1 button on the Action dashboard, all available Layer 1 actions appear. This category currently contains only one action: bad cable." Marvis can detect and alert for bad cables based on frame errors, link statistics, and AP/Switch behavior, all under the Layer 1 category. Connectivity, security, and client issues are handled under their respective action categories, but bad cabling is specifically monitored and detected as a physical (Layer 1) fault.

NEW QUESTION # 148
Which statement correctly describes the purpose of Juniper Mist "Virtual BLE" (vBLE)?
Answer: C
Explanation:
Virtual BLE (vBLE) leverages the AP's integrated BLE array combined with machine learning algorithms to provide accurate location services, effectively creating a "virtual" indoor GPS-like capability. This is part of Mist's overall location engine, providing granular location data without requiring extensive additional dedicated infrastructure.
NEW QUESTION # 149
When reviewing your site's SLEs, you notice a significantly high percentage of Asymmetry Uplink errors.
What do these errors indicate?
Answer: D
Explanation:
A high percentage of Asymmetry Uplink errors indicates coverage holes caused by asymmetric uplink strength between the AP and client devices. According to Juniper Mist's official documentation: "Asymmetry Uplink-Clients received a weak signal due to asymmetric uplink strength between the AP and the client device. (Uplink traffic is the traffic going from the client to the AP, and then to the Internet.) Asymmetry can occur for various reasons, such as clients being too far from the AP." This generally means that clients are physically located at a distance or behind obstacles (such as walls), causing the AP to detect weak signals from those clients. Coverage holes arise when APs are placed such that some areas have insufficient RF coverage, and the low-powered client devices cannot maintain reliable communication with the AP-even though the AP, with its higher transmit power, might hear the client, the client cannot send strong enough signals back. The SLE classifier is designed to highlight such areas for remediation, prompting network admins to review and enhance AP placement or signal thresholds.
