Juniper Mist AI, Associate (JNCIA-MistAI) Sample Questions (Q117-Q122):

NEW QUESTION # 117
Which Juniper Mist product enables the onboard Bluetooth Low Energy (BLE) antenna array for listen-only mode?

Answer: D

Explanation:
InJuniper Mist's Location-Based Services, theAsset Visibilityservice utilizes the built-inBluetooth Low Energy (BLE)antenna array within Mist Access Points to track BLE tags and devices inlisten-only mode.
This allows the APs to receive BLE signals emitted by assets and compute their real-time location usingangle- of-arrival (AoA)andRSSI-based triangulation.
According to theJuniper Mist Asset Visibility and Location Services Guide:
"When operating in Asset Visibility mode, the vBLE antenna array in Mist Access Points functions in listen- only mode, collecting BLE chirps from asset tags and relaying this data to the Mist Cloud for location determination." This configuration differs fromvBLE Engagement, where APs transmit BLE beacons to interact with mobile apps. InAsset Visibility, the BLE array passively listens to track tagged assets (e.g., equipment, IoT devices) across a defined floor map.
Therefore, the correct answer isD. Asset Visibility.

NEW QUESTION # 118
Which step must you take when configuring rogue AP detection?

Answer: A

Explanation:
Rogue AP Detection:
Rogue AP detection is crucial for maintaining network security by identifying unauthorized access points.
Configuration Step:
Enable Rogue AP Detection:
The first and necessary step in configuring rogue AP detection is enabling the feature in the Mist system.
Other Steps:
Setting proximity zones, disabling honeypot detection, and setting the RRM interval are additional configurations but not the initial or mandatory step.


NEW QUESTION # 119
Mist cloud supports single sign-on in which two scenarios? (Choose two.)

Answer: A,B


NEW QUESTION # 120
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?

Answer: A

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.
