Which two statements are correct about the Juniper Mist vBLE Asset Visibility mode? (Choose two.)
- A . The vBLE antenna is in the receive mode.
- B . The vBLE antenna tracks chirps from BLE tags.
- C . The vBLE antenna communicates with mobile devices running the Juniper Mist location SDK.
- D . The vBLE antenna is in the transmit mode.
Correct Answer: A, B
A, B
Explanation:
Juniper Mist’s virtual Bluetooth Low Energy (vBLE) technology is designed to deliver precise indoor location services using cloud-managed access points equipped with integrated BLE antenna arrays. The system supports multiple operational modes, including Engagement Mode (for mobile app interactions) and Asset Visibility Mode (for BLE tag tracking).
According to the Juniper Mist Location Services Documentation, in Asset Visibility Mode, the vBLE antenna functions primarily in receive mode to detect and process signals emitted from BLE asset tags. These tags periodically transmit Bluetooth “chirps” that are received by multiple APs. Mist Cloud then uses angle-of-arrival (AoA) and RSSI triangulation algorithms to determine the exact location of the asset within the facility.
The documentation specifies:
“In Asset Visibility Mode, the vBLE antenna operates in receive mode and listens for BLE tag beacons (chirps). The system triangulates these signals to calculate the real-time location of tracked assets.”
Conversely, Engagement Mode is the configuration in which vBLE operates in transmit mode to
interact with mobile devices running the Mist SDK ― which corresponds to location-based engagement or proximity notifications.
Thus, the correct answers are:

- C . Switch configurations at the site level are an additional way to apply a switch template to a specific site.
- D . Site-level switch configurations override org-level templates.
Correct Answer: C, D
C, D
Explanation:
In the Juniper Mist Cloud architecture, configuration hierarchy and inheritance are key design principles for managing EX Series and QFX Series switches under Wired Assurance. Configuration settings can be applied at both the organization level and the site level, with clearly defined precedence rules.
According to the Juniper Mist Wired Assurance Configuration Guide, the organization level defines global configuration templates that apply across multiple sites, while the site level provides customization options specific to a particular location or environment.
The documentation states:
“Site-level configuration overrides any global or organizational template configurations for switches within that site.”
and further clarifies:
“Administrators can create or modify switch templates at the site level to apply custom settings to specific deployments without affecting other sites under the same organization.”
Thus:
Statement C is correct ― site-level configurations are an additional method to apply templates for a specific site.
Statement D is correct ― site-level configurations take precedence over org-level templates.
Statement A is incorrect because org-level templates do not override site-level configurations; the reverse is true.
Statement B is incorrect because site-level configuration is not required for manual switch setup―it is an optional, more efficient method of template application.

- A . by alerting administrators of subscription options through e-mail
- B . by monitoring congestion uplink as a percentage of gateway bandwidth
- C . by using Predictive Analytics and Correlation Engine (PACE)
- D . by employing dynamic packet capture
Correct Answer: C, D
C, D
Explanation:
Juniper Mist Wireless Assurance revolutionizes network troubleshooting by implementing Predictive Analytics and Correlation Engine (PACE) and dynamic packet capture. According to the official Mist documentation, PACE applies advanced data science and machine learning to analyze real network events and classify them for root-cause identification. The Mist PACE engine proactively identifies issues by correlating over 150 client and AP state changes, enabling the system to surface recommendations and automate root-cause resolution. This allows IT teams to move beyond reactive troubleshooting towards predictive and automated network operations, reducing time-to-resolution and minimizing user impact.
Additionally, dynamic packet capture significantly streamlines troubleshooting efforts. Mist Wireless Assurance automatically detects anomalies or failures in user and network behavior and instantly initiates a packet capture. These packet captures are contextually tagged to the affected event, stored in the cloud, and are readily accessible for analysis. This process eliminates the need for on-site technicians with sniffers, as now every major incident already has an associated packet capture, captured at the right moment. This capability greatly reduces troubleshooting time and ensures that issues can be reproduced and isolated accurately.

Question #8
Which two statements are correct when considering Juniper Mist clouds? (Choose two.)
- A . Users created in a specific regional cloud can manage organizations in other clouds.
- B . Users created in a specific regional cloud can only manage organizations in that cloud.
- C . Creating a new user enables the user only for the cloud in which it was created.
- D . Creating a new user enables the user across all clouds.
Correct Answer: B, C
B, C
Explanation:
The Juniper Mist Cloud operates as a regionally distributed cloud infrastructure, where each geographic region (for example, US, EU, APAC) hosts its own isolated Mist Cloud instance. This design ensures compliance with regional data privacy regulations, improves network performance, and enhances scalability and reliability.
According to the Juniper Mist Cloud Administration and Operations Guide, user accounts and organizations are region-specific, meaning:
“Users and organizations exist within specific regional Mist Clouds. A user account created in one regional cloud is valid only within that region and cannot be used to access organizations hosted in another cloud.”
This structure ensures data sovereignty and security while maintaining logical separation between regions. When administrators create a new user, that user’s credentials and access privileges apply only to the Mist Cloud region in which the user was created.
Therefore:
B is correct because users created in a regional cloud can only manage organizations within that same cloud.
C is correct because a newly created user is enabled only for the regional cloud where it was registered.
Options A and D are incorrect because Mist Clouds are isolated ― cross-region user or organization access is not supported.

Question #9
Your organization currently uses Access Assurance for 802.1X authentication of wireless users using user certificates. All users are currently placed in the same VLAN after authentication.
There are multiple VLANs at your sites.
In this scenario, how would you configure Access Assurance to make the network more secure?
- A . Configure MAC Authentication Bypass (MAB) and assign WxLAN roles based on groups of MAC addresses.
- B . Configure user authentication using EAP-TTLS and assign WxLAN roles based on AD user group.
- C . Configure host (machine) authentication using EAP-TLS and assign WxLAN roles based on AD user group.
- D . Configure user authentication using EAP-TLS and assign WxLAN roles based on AD user group.
Correct Answer: D
D
Explanation:
Juniper Mist Access Assurance provides cloud-based network access control (NAC) by integrating RADIUS, identity-based policy enforcement, and WxLAN role-based segmentation. It allows administrators to assign users and devices to specific VLANs or network segments dynamically based on authentication attributes, thereby improving both security and policy granularity.
According to the Juniper Mist Access Assurance Configuration Guide, to enhance network security in a multi-VLAN environment, you should:
“Use EAP-TLS (certificate-based authentication) for secure user identification, and dynamically assign WxLAN roles or VLANs based on Active Directory (AD) group membership.”
Here’s why D is correct:
EAP-TLS ensures mutual authentication between client and RADIUS server using digital certificates ― preventing credential theft or spoofing.
Integrating with Active Directory allows role-based access control (RBAC), enabling dynamic VLAN or WxLAN assignment. This ensures users from different groups (e.g., staff, contractors, guests) are automatically segmented into appropriate network zones.
Option breakdown:
A (MAB): Used for non-802.1X devices (e.g., printers), less secure for user authentication.
B (EAP-TTLS): Username/password-based and less secure than certificate-based EAP-TLS.
C (Host authentication): Verifies devices only, not user identity―insufficient for user-level control. Therefore, the most secure and scalable configuration is:
✅ D. Configure user authentication using EAP-TLS and assign WxLAN roles based on AD user group.

Question #10
Which statement is correct about the relationship between Juniper Mist organizations and sites?
- A . A Juniper Mist superuser login grants access to all organizations.
- B . One Juniper Mist organization can contain multiple sites.
- C . You must have one Juniper Mist superuser login for each site.
- D . One Juniper Mist site can contain multiple organizations.
Correct Answer: B
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.
