Important Juniper JN0-452 JNCIS-MistAI-Wireless Exam Questions

Answer: D

Explanation:

If a customer wants to broadcast a WLAN at a certain time and day of the week, SSID scheduling should be configured

According to the SSID Scheduling - Mist document1, SSID scheduling is a feature that allows you to customize your WLAN by choosing the exact days and times to broadcast the SSID. This feature can be useful for scenarios where you want to limit the availability of a WLAN to a certain time and day of the week.

Answer: A, B

Explanation:

Channel bonding combines two adjacent channels to create a wider channel, effectively doubling the available bandwidth. However, this also doubles the required device resources such as power and processing.

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, channel bonding is a technique that combines two adjacent channels into one wider channel to increase throughput. This doubles the available bandwidth but also doubles the required device resources such as power and processing.

Answer: C

Explanation:

In this scenario, you would begin troubleshooting by checking the WLAN-level Pre-Shared Keys.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, you can configure a time-based setting for WLAN-level Pre-Shared Keys (PSKs) that will reset the key after a specified interval. This feature is useful for enhancing security and preventing unauthorized access. If a user reports that the Wi-Fi worked for a week and now it does not work, you should check the WLAN-level PSK settings and see if the key has been changed.

Answer: C

Explanation:

Basic data rates are the required data rates that all devices on a wireless network must support in order to connect to the network. These rates are used for management and control frames and can affect the performance of the network.

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, basic data rates are required data rates that all devices must support to communicate on a WLAN.

Answer: B

Explanation:

In Juniper Networks Mist AI Wireless, accurate location-based services (LBS) depend heavily on proper RF design and access point density. Juniper recommends that devices participating in Mist LBS maintain line-of-sight (LoS) to at least three access points to achieve reliable and consistent location accuracy.

Mist location services use advanced techniques such as RSSI triangulation, virtual BLE (vBLE), and AI-driven probability surface modeling to calculate a device's position. These algorithms require multiple independent signal measurements to accurately determine a device's X,Y coordinates. With signals received from three or more APs, Mist can triangulate the device position effectively and minimize errors caused by multipath reflections, attenuation, or transient RF noise.

If a device has line-of-sight to only one or two APs, the system lacks sufficient spatial diversity to calculate a precise location. This can result in ambiguous positioning, reduced accuracy, or excessive location ''drift.'' While additional APs (four or more) can further improve accuracy and stability---especially in high-value use cases such as asset tracking or wayfinding---three APs is the recommended minimum baseline for dependable LBS performance.

Mist's AI continuously evaluates signal quality, AP geometry, and environmental factors to refine location estimates, but it cannot compensate for insufficient AP visibility. As a result, Juniper best practices for LBS design emphasize:

Proper AP placement and height

Adequate AP density

Ensuring devices can ''see'' at least three APs at all times

The other options are incorrect because:

One or two APs do not provide enough data for reliable triangulation.

Four APs may improve accuracy but are not the minimum recommendation.

Therefore, the correct answer is B. 3.
