NEW QUESTION # 109
An administrator is troubleshooting poor location accuracy for vBLE asset tracking in a warehouse. After verifying AP placement and floorplan scale, they suspect an issue with the BLE tags themselves. They review the guidelines for supported BLE tags for use with Mist Asset Visibility.
Guidelines for BLE Beacon Tags:
- Interval Rate: 100 to 1000 milliseconds (ms)
- Power: 0 decibel milliwatt (dBm)
- MAC Address: Static
The administrator discovers the currently deployed tags are configured to transmit at a power level of -10 dBm.
How does this impact location accuracy?
Answer: A
NEW QUESTION # 110
At which signal strength level range will an extra AP placed on the same channel cause co- channel contention?
Answer: D
Explanation:
Co-channel contention occurs when an additional AP operates on the same channel within a strong signal range. At -45 dBm to -65 dBm, the AP signals are strong enough to overlap significantly, forcing clients and APs to share airtime and causing contention rather than interference.
NEW QUESTION # 111
Which signal modulation scheme provides the highest data rate level for 802.11ax devices?
Answer: D
Explanation:
In Juniper Networks Mist AI Wireless, understanding modulation schemes is essential for designing and operating high-performance Wi-Fi 6 (802.11ax) networks. Modulation directly affects how much data can be transmitted per symbol, and therefore determines the maximum achievable data rates under optimal RF conditions.
802.11ax introduces 1024-QAM (Quadrature Amplitude Modulation) as its highest supported modulation scheme. With 1024-QAM, each symbol encodes 10 bits of data, which represents a significant increase compared to earlier standards. For reference:
* 64-QAM (used in earlier standards) carries 6 bits per symbol
* 256-QAM (introduced in 802.11ac) carries 8 bits per symbol
* 1024-QAM increases this to 10 bits per symbol
This higher bit density allows Wi-Fi 6 devices to achieve higher peak throughput, especially in environments with excellent signal quality. However, 1024-QAM requires very high Signal-to-Noise Ratio (SNR) and low interference to function reliably. As a result, it is typically achieved only when clients are close to the access point and RF conditions are clean.
Mist AI Wireless continuously monitors client RSSI, SNR, retransmissions, and modulation rates through advanced telemetry. Using this data, Mist can determine whether clients are successfully operating at higher modulation levels like 1024-QAM or are falling back to lower schemes due to RF impairments. This insight directly feeds into SLEs and AI-driven recommendations for RF tuning, AP placement, and channel planning.
The incorrect options are explained as follows:
* 64-QAM and 256-QAM are valid modulation schemes but do not provide the highest data rates in
802.11ax.
* 4096-QAM is not supported by the 802.11ax standard and is therefore invalid.
Thus, 1024-QAM is the modulation scheme that provides the highest data rate level for 802.11ax devices.
NEW QUESTION # 112
Marvis Minis is a feature that helps administrators understand the scope of a network issue.
What does it do?
Answer: D
NEW QUESTION # 113
An administrator is reviewing the "Capacity" SLE for a site, which is showing poor performance due to high channel utilization. They want to implement a solution that will reduce co-channel interference in the crowded 2.4 GHz band by dynamically turning off some of the 2.4 GHz radios where coverage is already sufficient from neighboring APs.
Which Mist feature should be enabled in the site's RF Template?
Answer: A
