NEW QUESTION # 14
Using Juniper Mist, you want to claim multiple access points (APs) using a Web browser.
Where in the Juniper Mist Portal would you accomplish this task?
- A. Client Onboarding
- B. Subscriptions
- C. Devices
- D. Inventory
Answer: D
Explanation:
In Juniper Mist, allhardware device onboarding and claiming operations-including access points (APs), switches, and gateways-are performed under theInventorysection of the Mist Cloud Portal.
According to the Juniper Mist Cloud documentation, theInventorypage serves as the centralized location for device lifecycle management. It allows administrators to:
* Claim new devicesusing their serial numbers or activation codes.
* Batch import multiple APsvia manual entry or CSV upload.
* Assign claimed devicesto specific sites for configuration and management.
* Monitor device claim status, model type, firmware version, and cloud connectivity state.
The documentation specifies:
"To onboard or claim multiple access points in the Mist Cloud, navigate toOrganization # Inventory, then clickClaim Devices. Enter or paste serial numbers of the APs you want to add, and assign them to the appropriate site." Other options are incorrect because:
* Subscriptionsmanages licensing and service entitlements.
* Devicesshows active device status per site but does not handle claiming.
* Client Onboardingis used for guest access or authentication workflows, not hardware management.
Therefore, the correct answer isInventory (C).

NEW QUESTION # 16
What are two components of WiFi Management and Assurance? (Choose two.)
- A. Marvis Actions
- B. Dynamic Packet Capture
- C. wayfinding
- D. Radio Resource Management
Answer: B,D
Explanation:
Dynamic Packet Capture and Radio Resource Management (RRM) are two key components of WiFi Management and Assurance in Juniper Mist. According to official documentation: "Dynamic packet capture allows capturing wireless packets between clients and an access point to diagnose root-cause wireless issues.
For example, when a major issue is detected, such as an authorization failure, packet captures facilitate quick troubleshooting and root-cause analysis." RRM, driven by Mist's AI, proactively analyzes network conditions and client experiences to automatically adjust channel and power settings for optimal performance: "AI- driven RRM uses data science and cumulative SLE performance to learn and optimize radio settings, helping RF planning to continue to improve and adapt in the changing environments..." Marvis Actions is an AI-powered troubleshooting feature, but it is a separate component enabled by the Marvis subscription, not by base WiFi Management and Assurance. Wayfinding is part of the vBLE Engagement or location services.

Which Juniper Mist template would you use for this task?
- A. WAN Edge template
- B. RF template
- C. Switch template
- D. WLAN template
Answer: D
Explanation:
In theJuniper Mist Cloud architecture, aWLAN templateis used to define wireless network parameters, including SSIDs, authentication methods, and access control settings. These templates allow administrators to apply consistent Wi-Fi configurations across multiple access points and sites.
According to theJuniper Mist Wireless Assurance Configuration Guide, the WLAN template:
"Defines the configuration for SSIDs, including security mode (WPA2, WPA3, 802.1X), authentication servers, VLAN assignment, and user access policies." To configureWPA3/Enterprise (802.1X)security for employee SSIDs, administrators must create or edit a WLAN template and selectWPA3-Enterpriseas the security type. The template can then be associated with all sites in the organization, ensuring uniform deployment.
Other template types serve different purposes:
* Switch template:Used for wired configuration and port profiles.
* WAN Edge template:Used for SD-WAN and WAN Assurance configurations.
* RF template:Used to manage radio parameters such as channel, power, and band.

Exhibit:
Referring to the exhibit, which classifier was the largest contributor to 17% of the capacity issues?
- A. Wi-Fi Interference
- B. Ethernet
- C. Authorization
- D. Network Issues
Answer: A
Explanation:
Within theJuniper Mist Wireless Assurance dashboard, theCapacity SLE (Service Level Expectation) provides visibility into how well the network can handle concurrent users and traffic loads. It identifies the contributing factors, orclassifiers, responsible for degraded capacity performance such asWi-Fi interference, network issues, Ethernet problems, or authorization delays.
According to theJuniper 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."

NEW QUESTION # 30
You are creating a new site in the UI.
What are three required configuration settings in this scenario? (Choose three.)
- A. Country
- B. RF Template
- C. Site Name
- D. Active Hours
- E. Location
Answer: A,C,E
Explanation:
When creating a new site in the Juniper Mist User Interface, the three required configuration settings are Site Name, Country, and Location. According to Juniper Mist's official configuration guides: "At a minimum, enter the name, time zone, and location..." The 'Information' section of site setup requires the Site Name (a descriptive name to identify the site), Country (which sets regulatory and RF domain requirements), and Location (address or geo-coordinates for the site). These form the basis of the site identity in the Mist cloud and are mandatory for dashboard visibility, compliance, and baseline RF configuration. An RF Template, though critical for wireless tuning, is optional and can be assigned post-site creation. Active Hours are not required for the default site setup and are related to scheduling analytics or location-based services, not to the core creation workflow.
