Juniper Mist AI Wireless, Specialist JN0-452 JNCIS-MistAI-Wireless Exam Questions

Answer : C

According to the Mist documentation1, a Mist AP will pull a management IP address from the Native VLAN by default. However, if the Local Status Page is configured for the Site, all the site APs will pull their own IP address from the Management VLAN, but also addresses for each of the VLANs configured on the AP. This is because each AP creates a Switch Virtual Interface (SVI) for each VLAN on its eth0 interface.

The Local Status Page is a feature that allows you to access information about an AP's status and configuration through a web browser by connecting to its IP address2. This feature can be enabled or disabled at the site level under Site Settings > Access Points > Advanced Settings.

Answer : A, B, C

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide3, three types of devices that are counted by default for occupancy analytics are:

Mobile app clients, which are devices that have a mobile app installed with the Mist SDK or BLE beaconing enabled.

Cellular clients, which are devices that have cellular connectivity and can be detected by Mist APs using LTE sensing.

Wi-Fi clients, which are devices that have Wi-Fi connectivity and can be detected by Mist APs using Wi-Fi scanning.

Answer : C

If Bluetooth-only mobile client devices with an SDK-enabled app do not appear in the Mist GUI under Clients/App Clients even though they have Bluetooth enabled, it could be because the AP BLE radios do not hear the SDK-enabled client's BLE beacons.

According to the Mist documentation1, Mist SDK is a software development kit that enables indoor location and proximity services using Mist's virtual Bluetooth LE (vBLE) technology. The SDK allows mobile applications to communicate with Mist APs using BLE beacons that are transmitted by the client devices.

The devices with the SDK-enabled app have Bluetooth enabled, but they do not appear in the Mist GUI under Clients/App Clients because the AP BLE radios do not hear the SDK-enabled client's BLE beacons. This could be due to various factors such as interference, distance, obstacles, or configuration issues that affect the BLE signal strength and quality.

Answer : B, D

According to the Create a Mist Account and Organization - Mist document1, two fields that are required when creating a new site are:

Site name, which is a unique identifier for the site within the organization.

Time zone, which is used to display the correct time for events and reports related to the site.

Answer : C

According to the exhibit, the WLAN has a minimum basic rate of 24 Mbps for both 2.4 GHz and 5 GHz bands. This corresponds to the high-density data rate setting in Mist, which disables all data rates below 24 Mbps. This setting is recommended for high density designs, where clients have enough signal strength and quality to operate at higher rates.

Answer : A, B

Transmissions over Wi-Fi are shared medium and half-duplex.

According to the IEEE 802.11 - Wikipedia document2, two terms that correctly describe transmissions over Wi-Fi are:

Shared medium, which means that multiple devices use the same wireless channel and have to compete for access and avoid collisions.

Half-duplex, which means that devices can either transmit or receive data at a time, but not both simultaneously.

Answer : B

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, roaming is the process of moving a wireless client device from one AP to another while maintaining network connectivity. The client device determines when it is time to connect to another AP based on its own roaming algorithm and criteria.
