Q22. Which two statements are true about packet captures on an AP? (Choose two.)

The involved APs remain in service.

The involved APs are taken out of service.

Wireless and wired packets can be captured.

Only wireless packets can be captured.

Mist APs have the capability to capture both wireless and wired packets. This feature allows for comprehensive network troubleshooting by providing visibility into both types of traffic. When performing packet captures on Mist APs, the APs remain in service. This means they continue to operate and serve clients while the capture is ongoing, ensuring minimal disruption to network operations.
This functionality is critical for maintaining network availability and performance while conducting detailed packet analysis.

Q23. What are two user roles trial you ate allowed to assign to a new account? (Choose two.)

root

installer

guest

network admin

Installer: The installer role is designed for users who need access to configure and deploy Mist devices. This role typically has the necessary permissions to set up and manage devices but with limited access to other administrative functions (CertsHero).
Network Admin: The network admin role provides comprehensive access to manage network settings, monitor performance, and configure policies. This role is essential for users responsible for the overall network administration and maintenance (CertsHero).

Juniper Networks Documentation

Q24. What is the maximum number of Mist Edge devices supported for high availability?

A maximum of two Mist Edge devices are supported.

A maximum of 16 Mist Edge devices are supported.

An unlimited number of Mist Edge devices are supported.

A maximum of three Mist Edge devices are supported.

The maximum number of Mist Edge devices supported for high availability is two. This ensures that there is a backup device in place to take over in case the primary device fails, providing redundancy and maintaining network stability.

Q25. You want to troubleshoot a wireless client that is no longer connected to a Mist AP.
Which area within the Mist GUI would you use?

Monitor -> Service Levels -> Insights

Organization -> Audit Logs

Clients -> WiFi Clients

Clients -> App Clients

To troubleshoot a wireless client that is no longer connected to a Mist AP, you would navigate to the “Clients” section within the Mist GUI and select “WIFI Clients.” This area provides detailed information about all wireless clients that have connected to the Mist APs, including their connection history, performance metrics, and any issues encountered. By examining the data available in the WIFI Clients section, network administrators can identify the root cause of connectivity problems and take appropriate actions to resolve them.

Q26. How does Mist determine the location of clients in an indoor setting?

probability surface

triangulation

trilateration

GPS

This method leverages data from access points to create a probabilistic model of where clients are likely to be based on their signal strengths.

Q27. Which two statements are true about Juniper Mist Wireless Assurance Radio Resource Management (RRM)? (Choose two.)

RRM tuning happens automatically.

RRM builds the channel plan based on a real-time assessment of the network.

RRM tuning is a manual process that you must initiate every day.

RRM builds the channel plan based on the physical distance between the APs.

Real-time Assessment: Juniper Mist’s Radio Resource Management (RRM) builds the channel plan based on real-time network assessments. It dynamically adjusts to changing conditions in the RF environment, ensuring optimal performance by continuously monitoring factors such as interference, client distribution, and usage patterns. Automatic Tuning: RRM tuning happens automatically. Mist AI leverages reinforcement learning to continually optimize RF settings without manual intervention, adjusting channels, power levels, and other parameters in real-time to maintain optimal network performance.

Q28. Which machine learning method involves rewarding and punishing an agent?

unsupervised learning

supervised learning

deep learning

reinforcement learning

Q29. Which administrator role must you have to view audit logs?

Installer

Network Admin

Super User

Observer

Q30. What are asked to create a label that will be applied to a WLAN template.
This scenario, under which level should you create the label?

clients

organization

site

WLAN

When creating a label to be applied to a WLAN template in Mist AI, you should create the label at the site level. This is because WLAN templates are designed to be associated with specific sites or site groups, allowing you to customize WLAN configurations per site. Creating labels at the site level ensures that these configurations are applied appropriately within the desired site context.

Mist AI Documentation
Juniper Networks Site Groups

Q31. Manager asks you to set up a new WLAN that Is Open Access and does not allow any connected clients to communicate with each other, m the WLAN configuration, which feature would you use to separate the clients?

Filter ARP.

Configure geofence.

Hide SSID.

Configure isolation.

To set up a new WLAN that is Open Access and prevents connected clients from communicating with each other, you should use the Configure Isolation feature. This feature, often referred to as client isolation, ensures that each client can only communicate with the access point and not with other clients on the same WLAN.

Q32. Which unit of measurement is used for capacity, coverage, and throughput SLEs?

throughput in Mbps

percentage of channel utilization

signal strength in dBm

percentage of user minutes

For capacity, coverage, and throughput Service Level Expectations (SLEs) in Mist AI, throughput is measured in Mbps. This unit measures the rate at which data is successfully delivered over the wireless network, providing a clear indication of network performance and user experience. Mist AI tracks these metrics to ensure the network meets the required performance standards.

Q33. What are two benefits of Juniper Mist Wired Assurance? (Choose two.)

Ability to deploy campus fabric architectures in minutes based on intent.

It is the only way to configure Virtual Chassis settings for Juniper EX switches.

Support for ZTP.

Configuration settings for multi-gig access ports that are not available in the Junos CLI.

Juniper Mist Wired Assurance provides several benefits aimed at simplifying network management and enhancing performance.
Ability to deploy campus fabric architectures in minutes based on intent: Wired Assurance leverages automation and intent-based networking to quickly deploy and manage complex campus fabric architectures. This feature significantly reduces the time and effort required to set up and maintain such networks.
Support for ZTP (Zero Touch Provisioning): Wired Assurance includes ZTP capabilities, which allow for the automatic provisioning and configuration of switches as soon as they are connected to the network. This reduces the need for manual intervention and speeds up the deployment process.

Q39. You are asked to configure Mist lo send e-mail alerts lo your organization administrators, who all have mailboxes that reside on the same e-mail server. Alerts are being generated and are visible in the Mist GUI. but only some administrators are receiving the alert emails.
What Is the problem in this scenario?

The affected administrators have not enabled e-mail notifications in their Mist My Account settings.

The user e-mail addresses are not correctly formatted.

The organization does not have sufficient alert subscriptions.

Your e-mail server is blocking e-mail from Mist.

Identify the Problem: Alerts are being generated and visible in the Mist GUI, but only some administrators receive the alert emails.
Possible Issues:
User email addresses not correctly formatted.
Email server blocking Mist emails.
Insufficient alert subscriptions.
Administrators not enabling email notifications.
Root Cause:
Since some administrators receive the alerts, email formatting and server blocking issues can be ruled out.
If alert subscriptions were insufficient, no administrators would receive the alerts.
The most likely cause is that the affected administrators have not enabled email notifications in their Mist My Account settings.
Resolution:
Ensure that all administrators have enabled email notifications in their Mist My Account settings.
