Free Practice Questions for Juniper JN0-452 Exam

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide2, Dynamic Packet Capture is a feature that enables capturing packets from a client device and downloading them as a pcap file. This file can be used for troubleshooting purposes or sent to a vendor for analysis.

According to the JNCIS-MistAI Certification page3, a Marvis Actions Missing VLAN notification indicates that an access point is missing a VLAN that is configured on other access points in the same site.

When deploying multiple Mist APs across many sites in your network and grouping similar devices together to easily apply consistent WxLAN policies across multiple sites, you should use device profiles.

Two correct statements about Juniper Mist Dynamic Packet Capture are that no configuration is necessary for Mist’s Dynamic Packet Capture and it is automatically attached to a client event displayed on the Insights page. So the correct answers are A. No configuration is necessary for Mist’s Dynamic Packet Capture and B. It is automatically attached to a client event displayed on the Insights page.

According to the Marvis - Mist document, Correlation is a category in Marvis’ troubleshooting response that shows when the AP went offline. Correlation shows the correlation between events and SLEs for a given client or AP.

Juniper Mist separates its Location-Based Services (LBS) into distinct functional areas: User Engagement (vBLE-based) and Asset Visibility (tracking assets via Wi-Fi or BLE). Understanding the licensing and default behavior is crucial for a successful deployment.

The Wi-Fi location component is designed to track devices that are connected to the Wi-Fi network or are simply probing (unconnected). While basic connectivity data is part of the standard management, the high-fidelity tracking of these devices on a map as "assets" or "clients" for location analytics is tied to specific licensing tiers.

First, Wireless Assurance (B) provides the foundational telemetry and data collection required for basic location visibility. However, to unlock the full "Asset Tracking" capabilities—where the system actively correlates coordinates and provides historical data for specific Wi-Fi devices—the Asset Visibility subscription (D) is required. This subscription is what enables the Mist Cloud to process and store the location data for tags and Wi-Fi clients beyond simple real-time display.

Regarding the other options: Statement A is incorrect because the Wi-Fi location component tracks Wi-Fi devices; tracking BLE tags (third-party or otherwise) falls under the BLE/vBLE location component. Statement C is incorrect because location services are typically not enabled by default to protect user privacy and optimize performance. An administrator must manually upload a floor plan, scale it, and enable "Wi-Fi Engagement" or "Asset Tracking" within the Site settings or individual Access Point configurations to begin collecting location data. Once enabled and properly licensed, the Mist AI engine uses RSSI data from multiple APs to provide location coordinates for any Wi-Fi-emitting device in the environment.

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.

Two authentication methods that would be used with a guest portal are social login and external portal. So the correct answers are A. social login and B. external portal.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide2, two authentication methods that can be used with a guest portal are:

Social login, which allows guests to log in using their social media accounts such as Facebook, Twitter, or Google.

External portal, which allows guests to log in using an external web server that hosts a custom portal page.

In the Juniper Mist dashboard, the Marvis Actions page serves as a centralized "proactive inbox" that identifies critical issues across the organization. However, the depth of information and the ability to interact with these findings are strictly tied to the Marvis Virtual Network Assistant (VNA) subscription.

The Mist dashboard provides a basic level of visibility even without a full Marvis license, allowing administrators to see that certain high-level categories (such as AP, Switch, or Gateway) have identified issues. This is designed to demonstrate the value of the AI engine. However, when you see a lock symbol next to sub-categories or specific Marvis Actions, it indicates that the organizational account does not have an active Marvis VNA subscription for those specific devices.

Without the subscription, the system will not permit the user to "drill down" into the root cause analysis, view historical event timelines, or access the specific remediation steps suggested by the AI. For example, while a standard Wi-Fi Assurance license might show that an AP is offline, the Marvis VNA subscription is what enables the detailed investigation—such as determining if the offline status is due to a cable failure, a bad PoE port on a switch, or a firmware mismatch.

To unlock these features and remove the lock symbols, a SUB-VNA (Virtual Network Assistant) subscription must be applied to the access points in the site. Once licensed, Marvis can provide full "conversational AI" capabilities, allowing you to ask natural language questions about the APs and giving you the interactive tools needed to resolve the issues identified in the Actions dashboard. Therefore, the presence of the lock icon is a direct indicator of a missing or expired subscription tier required for advanced AI-driven troubleshooting.
