Which two statements are correct about Juniper Mist subscriptions? (Choose two.)

  1. Subscriptions are not associated with a specific device serial number.
  2. If a device fails and is removed from the network, you must manually transfer the subscription to the new device before installing.
  3. Subscriptions are associated with a specific device serial number.
  4. If a device fails and is removed from the network, the subscription will automatically apply to the new device when added.

Answer(s): A,D

Explanation:

In the Juniper Mist Cloud licensing model, subscriptions represent service entitlements that enable specific features such as Wireless Assurance, Wired Assurance, WAN Assurance, Marvis Virtual Network Assistant, and Premium Analytics. These subscriptions are managed at the organization level and are not permanently tied to individual hardware units.

According to the Juniper Mist Licensing and Subscription Management Guide, subscriptions are:

"Cloud-based entitlements associated with an organization, not bound to specific device serial numbers. Devices draw from the subscription pool dynamically."

This design allows flexibility and simplifies device replacement or scaling:

When a new device (for example, an access point or switch) is added to the organization, the subscription is automatically assigned to it from the available pool.

If a device is removed or fails, the subscription is automatically released and reassigned to a replacement unit--no manual transfer is required.

Therefore:

A is correct because subscriptions are not linked to a single device's serial number.

D is correct because subscriptions automatically reapply when replacement devices are onboarded.

Options B and C are incorrect because Juniper Mist subscriptions are organization-based, not hardware-bound, and require no manual reassignment after device failure or replacement.

Exhibit:



Referring to the exhibit, which classifier was the largest contributor to 17% of the capacity issues?

  1. Network Issues
  2. Ethernet
  3. Authorization
  4. Wi-Fi Interference

Answer(s): D

Explanation:

Within the Juniper Mist Wireless Assurance dashboard, the Capacity SLE (Service Level Expectation) provides visibility into how well the network can handle concurrent users and traffic loads. It identifies the contributing factors, or classifiers, responsible for degraded capacity performance such as Wi-Fi interference, network issues, Ethernet problems, or authorization delays.

According to the Juniper Mist AI Operations and SLE Analytics Guide, the platform:

"Uses classifiers to break down SLE metrics and identify which network factors most heavily contribute to sub-threshold performance."

In the exhibit, the Wi-Fi interference classifier has the longest bar reaching the full 17%, clearly showing it as the largest contributor to capacity degradation. Wi-Fi interference occurs when multiple APs or nearby wireless networks overlap on the same channel, resulting in increased contention, collisions, and reduced airtime availability -- all of which impact overall capacity.

Therefore, the correct answer is D. Wi-Fi Interference.

Which statement is correct about the Super User account role?

  1. The Super User role has limited read/write capabilities.
  2. The Super User role is restricted to the specific sites that are defined when creating the user account.
  3. You must use the Super User role to claim an organization's new AP.
  4. You must use the Super User role to add administrators to an organization.

Answer(s): D

Explanation:

In the Juniper Mist Cloud platform, user roles define the scope of permissions that determine what administrative functions an individual can perform within an organization. The Super User role represents the highest level of administrative authority within a Juniper Mist organization and carries full control over both organization-wide and site-specific configurations.

According to the Juniper Mist Cloud Administration and User Management documentation, the Super User role is described as:

"The Super User role provides full read and write access across the entire organization. Only Super Users can manage organization-level settings, add or remove other administrators, and assign privileges to users."

This means that only a Super User can add new administrators, manage subscription entitlements, configure organization-level policies, and perform full lifecycle device management. Unlike site administrators, Super Users are not restricted to specific locations--they have unrestricted visibility and control across all sites within the organization.

Therefore, the correct answer is D, since the Super User role is explicitly required to add administrators to an organization and perform top-level management operations.

Mist AI collects and integrates data from multiple sources, including the data science and customer success teams and the domain experts. This process improves ML/AI accuracy.
What is this process called?

  1. Anomaly detection
  2. Mist AI efficacy loop
  3. Bayesian inference
  4. Marvis Actions

Answer(s): B

Explanation:

The Mist AI Efficacy Loop is a key concept within the Juniper Mist AI architecture that ensures continuous improvement of its machine learning (ML) and artificial intelligence (AI) models. This process combines feedback and data collected from multiple sources -- including real-world network telemetry, customer success feedback, domain experts, and the Mist data science team -- to refine the AI algorithms and enhance prediction accuracy.

According to the Juniper Mist AI Operations and Architecture Guide, the process is described as follows:

"The Mist AI efficacy loop is a closed-loop feedback system that continuously collects data from the field, correlates it with expert knowledge and support insights, and uses it to retrain and improve AI models for greater accuracy and reliability."

This iterative learning cycle allows Mist AI to:

Improve anomaly detection precision.

Reduce false positives in network issue detection.

Enhance Marvis's ability to accurately identify root causes and recommend corrective actions.

The efficacy loop is what differentiates Mist AI from static analytics platforms, as it creates a self-

learning system that evolves with every deployment and customer interaction.

Therefore, the correct answer is B. Mist AI efficacy loop.

Which two statements are correct about the switch configuration hierarchy in Juniper Mist? (Choose two.)

  1. The switch configuration cannot be managed at the organization level.
  2. The switch templates exist at the organization level.
  3. The switch templates exist at the site level.
  4. The switch-specific configuration cannot override switch templates.

Answer(s): B,C

Explanation:

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.
