QUESTION: 1

What are two ways that Juniper Mist Access Assurance enforces network access control? (Choose two.)

It creates a VPN using an IPsec tunnel.
It monitors network traffic.
It assigns specific roles to users.
It groups users into network segments.

Answer(s): C,D

Explanation:

Juniper Mist Access Assurance is a cloud-based network access control service that provides secure wired and wireless access through identity- and policy-based mechanisms. According to the official Juniper Mist AI documentation, Access Assurance uses user and device identity to determine network access privileges dynamically.

The service enforces access policies primarily in two ways:

Assigning Specific Roles to Users:

Access Assurance dynamically assigns roles to users and devices after successful authentication. These roles are used to apply specific network policies and permissions, defining what level of access or network resources a user or device is allowed. Roles can be leveraged in wireless SSID configurations or switch access policies to ensure consistent enforcement across the infrastructure.

Grouping Users into Network Segments:

Access Assurance also allows grouping of users and devices into network segments using VLANs or Group-Based Policy (GBP) technology. This segmentation isolates users or devices into logical groups, ensuring security and optimized traffic handling. Policies are then applied to these groups to control communication between segments, thereby maintaining a zero-trust framework.

Options A and B are incorrect because Access Assurance does not establish VPN tunnels or passively monitor traffic as its primary method of access control. It relies instead on identity-based role assignment and segmentation to enforce network security.

QUESTION: 2

Which statement is correct about the relationship between Juniper Mist organizations and sites?

A Juniper Mist superuser login grants access to all organizations.
One Juniper Mist organization can contain multiple sites.
You must have one Juniper Mist superuser login for each site.
One Juniper Mist site can contain multiple organizations.

Answer(s): B

Explanation:

According to the official Juniper Mist documentation on the configuration hierarchy, the platform uses a three-tier model: Organization Site Device. At the organization level, you manage administrator accounts, subscriptions, and organization-wide settings. Then:

"An organization can include one or more sites. A site can represent a physical location or a logical subdivision of your enterprise or campus."

Also, in the simpler case explanation:

"Each customer is created as a separate organization. Within that organization multiple sites can be created."

Mist

These statements make clear that the correct relationship is: one organization may have multiple sites under it. The inverse -- that a site might contain multiple organizations -- is not supported in the documented hierarchy. Therefore option B is correct.

QUESTION: 3

Exhibit:

Referring to the exhibit, which Roaming Classifier is responsible for the sub-threshold SLEs?

Signal Quality
WiFi Interference
Ethernet
Capacity

Answer(s): D

Explanation:

In the Juniper Mist dashboard, Service Level Expectations (SLEs) are metrics that measure user experience in key areas such as connection, throughput, and roaming. Each SLE is composed of classifiers, which help identify the underlying cause of degraded performance or sub-threshold scores.

According to the Juniper Mist AI documentation, the Roaming SLE tracks client transitions between access points and evaluates the quality of those roaming events. The contributing classifiers typically include Signal Quality, Wi-Fi Interference, Ethernet, and Capacity.

In this exhibit, the bar for Capacity is the longest under the "Roaming Classifiers" section, indicating that it has the most significant impact on the Sub-Threshold SLE value (10.6%). This means roaming performance is primarily being limited by insufficient capacity -- often due to AP radio congestion or a high number of concurrent clients impacting handoff efficiency.

Hence, the Capacity classifier is responsible for the sub-threshold SLEs.

QUESTION: 4

How do Wireless Assurance SLEs help administrators troubleshoot?

They help streamline the onboarding process.
They manage Juniper Mist subscriptions.
They customize the Guest User portal.
They set benchmarks for network performance and user experiences.

Answer(s): D

Explanation:

In Juniper Mist AI, Wireless Assurance Service Level Expectations (SLEs) are designed to provide AI- driven visibility into user experience and network performance. Each SLE represents a specific aspect of the end-user journey -- such as Time to Connect, Throughput, Coverage, Roaming, Capacity, and Application Experience.

According to the Juniper Mist documentation, SLEs "define measurable benchmarks for user experience and identify where deviations occur." This allows administrators to quickly determine whether issues stem from client devices, access points, wired uplinks, or WAN connectivity.
When an SLE metric falls below its threshold, Mist AI automatically highlights the affected classifier (for example, DHCP, DNS, or Wi-Fi interference) and provides root-cause correlation through AI-driven insights.

This data-driven approach enables administrators to troubleshoot proactively by focusing on user- impacting areas instead of raw device statistics. Thus, Wireless Assurance SLEs act as experience- based benchmarks that simplify troubleshooting, improve performance visibility, and shorten mean time to repair (MTTR).

QUESTION: 5

You are asked to create a real-time visualization dashboard which displays clients on a map.

Which two Juniper Mist functions would you use in this scenario? (Choose two.)

Webhooks
RESTful API
WebSocket
Live View

Answer(s): C,D

Explanation:

When developing a real-time visualization dashboard that displays client locations on a map, Juniper Mist offers specific APIs and data streaming methods to support dynamic updates.

According to the Juniper Mist Developer Documentation, the WebSocket interface enables continuous, real-time streaming of client location and telemetry data directly from the Mist Cloud. This mechanism is ideal for live dashboards, as it eliminates the need for repeated REST API polling. WebSocket connections provide instant updates whenever a device moves, connects, or disconnects, ensuring the displayed map remains accurate in real time.

The Live View feature complements this functionality within the Mist Cloud and third-party integrations. It allows administrators and developers to view live location movements of Wi-Fi clients, BLE beacons, and IoT devices within a site's floor plan. It uses telemetry directly from access points, offering second-by-second updates.

In contrast, RESTful APIs and Webhooks are designed for event-based automation and configuration management rather than live visualization. REST APIs are best for historical or static data retrieval, while Webhooks are used for triggering external actions based on events.

Therefore, the correct functions for real-time map visualization are:

WebSocket (C) -- for continuous live data streaming

Live View (D) -- for direct map-based visualization of client activity
