Juniper Mist Cloud Fundamentals and Juniper Mist Configuration Basics typically account for a larger portion of the exam because they form the foundation for all operational tasks. However, Juniper Mist Monitoring and Analytics and Marvis Virtual Network Assistant AI are increasingly important, as they reflect how modern Mist deployments rely on AI-driven insights. Review the official exam blueprint to confirm current topic weightings.
Cloud fundamentals teach you why Mist uses a multi-tenant SaaS model and how regional deployments work, while configuration basics show you how to actually set up networks within that cloud infrastructure. In practice, understanding the cloud architecture helps you make better decisions about where to deploy access points, how to organize sites, and how to manage user roles across multiple locations. These two domains work together to ensure your configuration aligns with the scalability and security benefits of the cloud platform.
Hands-on experience with a Mist dashboard is highly beneficial but not mandatory if you study carefully. Prioritize labs that let you configure SSIDs, set authentication policies, and interpret the analytics dashboard. If you have access to a Mist trial or sandbox environment, focus on tasks like adding an access point, creating a network policy, and reviewing the Marvis AI recommendations. This practical exposure reinforces conceptual knowledge and builds confidence for scenario-based questions.
Many candidates confuse cloud-based operations with on-premises wireless management and miss nuances around Mist's role-based access control and multi-tenant design. Others underestimate the importance of Marvis AI recommendations and location-based services, which are core to modern Mist deployments. A frequent error is selecting a technically correct answer that doesn't address the most efficient or recommended approach in a Mist context. Carefully read scenario questions to identify what the question is really asking and choose the best Mist-native solution, not just any working solution.
In the final week, focus on weak topic areas identified during practice tests rather than re-reading all material. Complete one full-length timed practice test to simulate exam conditions and identify remaining gaps. Review the explanations for questions you missed, paying special attention to why the correct answer is better than the alternatives. In the last 2-3 days, do a quick review of key definitions, common Mist workflows, and Marvis use cases to keep concepts fresh without overloading yourself.
Which two statements are correct about the switch configuration hierarchy in Juniper Mist? (Choose two.)
The Juniper Mist Wired Assurance platform uses a hierarchical configuration model to manage switch settings efficiently across organizations and sites. This hierarchy provides flexibility by allowing administrators to apply global configurations through templates at the organization level, while also permitting site-specific customizations.
According to the Juniper Mist Wired Assurance Configuration and Template Management Guide, the configuration hierarchy functions as follows:
''Switch templates can be created at both the organization and site levels. Organization-level templates define global configurations, while site-level templates provide location-specific customization that overrides the organization-level settings where applicable.''
This structure enables consistent policy deployment while preserving site autonomy for unique configurations. For example, global VLAN or QoS configurations can be managed at the organization level, and local templates can adjust settings for switch ports or device groups at specific sites.
Switch-specific overrides are allowed within the hierarchy, ensuring flexibility in cases where unique port or feature configurations are required.
Therefore:
B is correct because switch templates exist at the organization level for global use.
C is correct because switch templates also exist at the site level for localized adjustments.

Your existing environment has Cisco wireless access points (APs) that use preshared keys to authenticate wireless users. You are asked to enable Juniper Mist Access Assurance for 802.1X (RADIUS) user authentication on these Cisco APs.
How would you accomplish this task?
To enable Juniper Mist Access Assurance for 802.1X (RADIUS) authentication with Cisco APs, the correct approach is to configure a new 802.1X SSID on the Cisco AP referencing your Juniper Mist Edge as the RADIUS server (option C). According to Juniper Mist's official documentation and architecture guides: ''Mist Access Assurance supports end-client authentication on third-party infrastructure by leveraging the Mist Auth Proxy application running on a Mist Edge platform. Third-party devices, such as Cisco APs, are added as RADIUS clients at Mist Edge. The Mist Edge proxy handles all RADIUS authentication traffic from the APs, wraps these authentication requests into a secure RadSec tunnel, and relays them to the Mist Access Assurance cloud for validation against configured authentication rules.''
This deployment does not require direct RADSEC tunneling from Cisco APs to Mist Access Assurance (since Cisco APs are not natively RADSEC capable) but uses Mist Edge as an intermediary RADIUS server and authentication proxy. 'Add an authentication rule in Access Assurance to permit user access,' enabling centralized management and policy enforcement in the Mist Cloud.

Which two configuration elements are available in a WLAN template? (Choose two.)
In the Juniper Mist Cloud, a WLAN template is used to standardize and simplify the configuration of wireless networks across multiple sites. Templates define common wireless parameters, ensuring consistent deployment and easier scalability while reducing configuration errors.
According to the Juniper Mist Wireless Assurance Configuration Guide, WLAN templates contain several configurable elements that define how the wireless network operates, including:
Radio Management (A)
This element controls RF parameters such as transmit power, channel width, and radio band assignments (2.4 GHz / 5 GHz / 6 GHz). It leverages Mist's AI-driven Radio Resource Management (RRM) to optimize RF performance across APs dynamically.
WLANs (D)
The template includes WLAN definitions (SSIDs) with associated settings such as authentication type, VLAN assignment, access control policies, and bandwidth limitations. WLANs can be linked to specific sites through these templates for unified management.
The other options are incorrect:
Template Policies (B) are not a defined component within WLAN templates---they refer to higher-level configuration management.
Organizations (C) exist at the top hierarchy level in Mist Cloud (above sites and templates) and are not configured within a WLAN template.
Therefore, the two correct configuration elements available in a WLAN template are:
A . Radio management
D . WLANs

Which three categories of alert types are available in Juniper Mist? (Choose three.)
Alerts represent network and device issues that are ongoing. Juniper Mist categorizes them as follows:
Infrastructure Alerts---Repeated events involving servers and protocols that can potentially affect a large number of clients. For example, an event during which a Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), or RADIUS server is unreachable can affect many clients. Similarly, if a power supply on a switch is in alarm state, a large number of clients and a large amount of traffic could be affected.
Marvis Alerts---Repeated events that Marvis tracks on the Marvis Actions dashboard. For example, if an access point (AP) regularly fails health checks, you'll see a Marvis alert for it.
Security Alerts---Repeated events that could dramatically affect network security. For example, these alerts appear if a rogue AP is detected and clients start connecting to it.
Certificate Alerts---Notification for expired, and soon-to-expire, user-added digital certificates. These include RadSec (configured at Organization > Settings > RadSec Certificates and AP RadSec certificate), SSO (configured at Organization > Settings > Single Sign-On), and PSK Portal IDP certificates (configured at Organization > Client Onboarding). Certificate alerts appear on the Alerts page and begin 30 days before the certificate's expiry date, then the notification repeats 15, 7, 3, and 1 day before expiration unless the certificate is renewed. .
Which machine learning method uses unlabeled data sets?
In Juniper Mist AI, various machine learning (ML) techniques are applied across the platform to analyze network telemetry and improve performance insights. Among these, unsupervised learning plays a critical role in identifying patterns, trends, and anomalies in unlabeled datasets---data that has not been pre-classified or annotated.
According to the Juniper Mist AI and Machine Learning Overview:
''Unsupervised learning enables Mist AI to automatically detect abnormal patterns or clusters in large volumes of unlabeled network data, allowing the system to identify anomalies and optimize network behavior without human labeling.''
This method allows Mist AI to autonomously recognize deviations in user experience, traffic behavior, or radio performance without prior definitions, helping to enhance predictive analytics and anomaly detection.
By contrast:
Supervised learning requires labeled training data.
Reinforcement learning learns through trial-and-error feedback loops.
Cognitive learning is not a formal ML category---it refers to human-inspired reasoning.
Therefore, the correct answer is D. Unsupervised learning.
