NEW QUESTION # 20
You are asked to display your network devices using the Juniper Mist GUI as a single solution. Your network is made up of a wireless infrastructure of only Juniper APs, and the wired infrastructure has a mix of Juniper and non-Juniper switches. Your solution must ensure that all devices are displayed in the Juniper Mist GUI.
Given this scenario, how would you accomplish this task?
- A. Use Wi-Fi Management and Assurance with LLDP enabled on all switches.
- B. Use Wired Assurance with the Monitoring option.
- C. Use Juniper Mist Asset Visibility.
- D. Use Juniper Mist Marvis Actions.
Answer: C
Explanation:
The appropriate solution is Juniper Mist Asset Visibility (option C). Asset Visibility is a cloud service that leverages Juniper Mist Access Points and virtual Bluetooth Low Energy (vBLE) technology to track, locate, and display all network devices-including both Juniper and non-Juniper hardware-within the Mist GUI.
According to the official Juniper documentation: "Juniper Mist Asset Visibility unites Wi-Fi connectivity, indoor location services for asset tracking, and IoT visibility in a single cloud platform. By combining vBLE with the Mist Cloud, organizations can use the same infrastructure-even when wired switches are from different vendors-for locating, tracking, and analyzing their most valuable assets and network devices." This capability is independent of switch manufacturer and provides comprehensive visualization of wireless APs and connected wired devices, ensuring a true single-pane-of-glass management experience. Wired Assurance, Marvis Actions, and LLDP-enabled Wi-Fi Management may provide visibility and proactive troubleshooting, but only Asset Visibility guarantees display and tracking of all assets-Juniper and non- Juniper-in the Mist GUI.

NEW QUESTION # 21
Which two statements are correct about the Juniper Mist vBLE Asset Visibility mode? (Choose two.)
- A. The vBLE antenna is in the transmit mode.
- B. The vBLE antenna is in the receive mode.
- C. The vBLE antenna communicates with mobile devices running the Juniper Mist location SDK.
- D. The vBLE antenna tracks chirps from BLE tags.
Answer: B,D
Explanation:
Juniper Mist'svirtual Bluetooth Low Energy (vBLE)technology is designed to deliverprecise indoor location servicesusing cloud-managed access points equipped with integrated BLE antenna arrays. The system supports multiple operational modes, includingEngagement Mode(for mobile app interactions) and Asset Visibility Mode(for BLE tag tracking).
According to theJuniper Mist Location Services Documentation, inAsset Visibility Mode, the vBLE antenna functions primarily inreceive modeto detect and process signals emitted fromBLE asset tags. These tags periodically transmit Bluetooth "chirps" that are received by multiple APs. Mist Cloud then usesangle-of- arrival (AoA)andRSSI triangulation algorithmsto 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 Modeis the configuration in which vBLE operates intransmit modeto interact with mobile devices running the Mist SDK - which corresponds to location-based engagement or proximity notifications.
Thus, the correct answers are:
* A. The vBLE antenna is in the receive mode
* B. The vBLE antenna tracks chirps from BLE tags

NEW QUESTION # 22
Exhibit:
Referring to the exhibit, which percentage of Coverage was unsuccessful?
- A. 15%
- B. 21%
- C. 9%
- D. 79%
Answer: B
Explanation:
InJuniper Mist Wireless Assurance, theCoverage SLE (Service Level Expectation)measures the quality and consistency of Wi-Fi signal coverage across an organization's wireless infrastructure. It provides insight into how well clients can connect to access points with sufficient signal strength and quality.
According to theJuniper Mist AI Operations and Analytics Guide, the Coverage SLE is defined as:
"The percentage of client connections that meet the minimum signal strength threshold required for satisfactory performance. Sub-threshold values represent areas where coverage is inadequate or inconsistent." In the exhibit, the SLE visualization shows79% successful coverageand21% unsuccessful coverage, meaning that21% of connection attempts or client areas did not meet the desired signal strength threshold. These failures may be caused by factors such as:
* Insufficient AP density or placement.
* RF interference from neighboring devices.
* Physical obstructions impacting signal propagation.
Thus, theunsuccessful coverage percentage is 21%, indicating potential areas where additional APs or configuration optimization may be needed to improve user experience.

NEW QUESTION # 23
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.
Answer: D
Explanation:
Juniper Mist Access Assuranceprovidescloud-based network access control (NAC)by integratingRADIUS
,identity-based policy enforcement, andWxLAN role-based segmentation. It allows administrators to assign users and devices to specific VLANs or network segments dynamically based on authentication attributes, thereby improving bothsecurityandpolicy granularity.
According to theJuniper 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 whyDis correct:
* EAP-TLSensuresmutual authenticationbetween client and RADIUS server using digital certificates
- preventing credential theft or spoofing.
* Integrating withActive Directoryallowsrole-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.

NEW QUESTION # 25
You are asked to enable Mist management at an existing site with previously configured EX3400 brownfield switches, and to add a new greenfield switch.
Which statement is correct in this scenario?
- A. Brownfield switches can be adopted but not managed.
- B. You cannot mix greenfield and brownfield switches at the same site.
- C. You can mix brownfield switches and greenfield switches as long as they are running a Mist- supported version of Junos.
- D. You can mix brownfield switches and greenfield switches at the same site, but only if they are running the same version of Junos.
Answer: C
Explanation:
In the context of Mist management, "brownfield" switches refer to those that are already configured and deployed in a network, while "greenfield" switches are new and have no pre- existing configuration.
Mist supports the integration and management of both brownfield and greenfield switches within the same site. The crucial requirement is that all switches, regardless of their initial state, must be running a version of Junos that is supported by Mist. This compatibility ensures that Mist can apply policies, configurations, and monitoring uniformly across all devices, facilitating a seamless management experience.
NEW QUESTION # 26
What are three methods for requesting authentication in the Juniper Mist API? (Choose three.)
- A. Use OAuth2 linked to an OAuth provider.
- B. Use an HTTPS login with a user name and password.
- C. Enable basic authentication with a token.
- D. Use RADIUS certificates.
- E. Enable MFA with Okta Verify.
Answer: A,B,C
Explanation:
The three valid methods for requesting authentication with the Juniper Mist API are:
Use an HTTPS login with a user name and password: The Mist API accepts HTTPS requests where credentials are provided directly for session/token generation and user administration.
Use OAuth2 linked to an OAuth provider: "Juniper Mist APIs offer authentication via OAuth2 with various OAuth-compatible identity providers, such as Okta, for secure and federated access." Enable basic authentication with a token: Mist APIs accept programmatic requests using tokens (API tokens or bearer tokens) for automation, scripting, and integration-each token mapping to specific scopes and user permissions.
Enabling MFA with Okta Verify enhances user portal security but is not an API authentication mechanism.
RADIUS certificates are used for infrastructure 802.1X authentication, not for API access.
