Juniper JN0-452 - Mist AI Wireless - Specialist (JNCIS-MistAI-Wireless)

If a customer added an Apple TV in their conference room so that employees can easily share their screen but the Apple TV cannot be discovered by the employees’ devices, two settings that could be causing this problem are MDNS and Broadcast/Multicast. So the correct answers are A. MDNS and B. Broadcast/Multicast.

When a customer replaces their previous WLAN controller with a Mist Edge in order to maintain centralization of user traffic, control plane forwarding applies to the Mist Cloud while data plane forwarding applies to the Mist Edge. So the correct answer is A. Control plane forwarding applies to the Mist Cloud and data plane forwarding applies to the Mist Edge.

Syslog is a protocol that can be used to forward event messages from Mist to an external log collector.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, syslog is a feature that enables forwarding event messages from Mist to an external log collector. Syslog messages can be sent over UDP or TCP protocols.

According to the Webhooks - Mist document, two types of information that would be streamed through webhooks are:

Alerts, which are notifications that are triggered by certain events or conditions on the network.

SLE metrics of clients, which are service level expectations that measure the quality of experience for clients on various aspects such as connection, coverage, capacity, throughput, and roaming.

In Juniper Networks Mist AI Wireless, access points must be claimed to an organization in the Mist cloud before they can be configured, monitored, and managed. When deploying APs at scale, Juniper provides an efficient mechanism to onboard multiple access points simultaneously using an activation code.

An activation code is a bulk-claim method generated within the Mist cloud portal. This code is typically associated with a purchase order or shipment and can represent dozens, hundreds, or even thousands of access points. When the activation code is applied to an organization, all APs tied to that code are automatically claimed at once. This approach is especially valuable for enterprise and campus deployments, where manual per-device onboarding would be impractical.

Once claimed using an activation code, APs can be assigned to sites, receive configurations, and leverage Zero-Touch Provisioning (ZTP). As soon as the APs obtain network connectivity and reach the Mist cloud, they automatically download their configuration and become operational without further manual intervention.

The other options are incorrect for the following reasons:

QR codes are used for claiming individual APs, typically during small deployments or troubleshooting scenarios.

Digital certificates are used for secure authentication and communication but are not a method for claiming APs to an organization.

The Juniper Mist Mobile Application can assist with onboarding and visibility but does not provide a bulk-claim mechanism for large numbers of APs.

Therefore, the correct and documented method for claiming multiple Juniper Access Points simultaneously is to use an activation code, making option A the correct answer.

When deploying three WLAN 2.4 GHz networks in your US-based site while ensuring that each network frequency is unique and does not overlap with other frequency channels, you should use OFDM channels 1, 6 and 11. So the correct answers are B.1, D.6, and A.11.

 According to the Data Rates - Mist document1, a honeypot AP is an AP that is not associated with your network, but broadcasts your corporate login page and WLAN name. This is a type of rogue AP that tries to trick users into connecting to it and revealing their credentials or other sensitive information.

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.

In a Juniper Mist AI deployment, achieving high-fidelity location accuracy is entirely dependent on the digital twin (the floor plan in the Mist UI) accurately reflecting the physical environment. While scaling the map is the foundation, AP orientation is the most critical variable for the vBLE (virtual Bluetooth Low Energy) engine to correctly calculate a client's position.

Mist Access Points, such as the AP43 or AP45, feature a patented 16-element directional vBLE antenna array. This array does not broadcast in a simple omnidirectional circle; instead, it uses eight distinct directional beams to blanket an area. The Mist Cloud uses "probability surfaces" to determine a user's location by examining the RF fingerprints from these specific beams. If an AP is physically mounted with its LED pointing toward a specific hallway, but is oriented in the Mist UI facing a different direction, the location engine will receive signal data that does not match its internal map of the beams. This results in "flipped" locations or "teleporting," where a user appears on the opposite side of the AP from where they actually are.

To ensure accuracy, administrators must use the small green dot on the outer ring of the AP icon in the Mist Live View. This green dot represents the physical LED on the AP hardware. The orientation in the UI must be rotated so that the green dot points in the exact same direction as the physical LED relative to the floor plan's perspective. It is a common misconception that APs must face true north (A) or geographical north (D); the map and APs can be oriented in any way that is convenient for the facility layout, provided the relative alignment between the virtual icon and the physical device is identical.
