Juniper Mist AI Wireless, Specialist (JNCIS-MistAI-Wireless) 認定 JN0-452 試験問題 (Q49-Q54):

質問 # 49
You want to push real-time events such as AP up/down or restart to a provided URL. In this scenario what would you use to accomplish this task?

正解：B

解説：
Webhooks in Juniper Mist allow you to push real-time events (such as AP up/down or restarts) to a specified URL. This enables automated workflows and integrations with third-party monitoring or ticketing systems.


質問 # 50
Which 802.11 amendment, also known as Wi-Fi 6, introduced Orthogonal Frequency-Division Multiple Access (OFDMA) to improve efficiency in high-density environments?

正解：A


質問 # 51
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?

正解：A

解説：
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.


質問 # 52
You are asked to ensure that your office WLAN is only being broadcast and usable during your normal office hours. The WLAN should not be visible or available during non-working hours. Your solution should be automatic and not require manual intervention every day. In this scenario, which Juniper Mist feature will accomplish this task.

正解：B

解説：
SSID Scheduling allows you to automatically control when a WLAN is broadcast. By configuring office hours, the SSID will only be visible and usable during working hours and will be hidden outside of that schedule without requiring daily manual changes.


質問 # 53
According to the 802.11 standard, how wide are 2.4 GHz band OFDM channels?

正解：A

解説：
Reference: https://www.cnrood.com/en/media/solutions/Wi-Fi_Overview_of_the_802.11_Physical_Layer.pdf According to the 802.11 standard, OFDM channels in the 2.4 GHz band are 20 MHz wide.
According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, OFDM channels in the 2.4 GHz band are 20 MHz wide according to the 802.11 standard.
