The maximum number of nodes supported in a Mist Edge high availability cluster is three.

This configuration ensures high availability and redundancy, providing resilience and reliability for network operations.

By having three nodes, the cluster can continue to operate effectively even if one node fails, ensuring minimal disruption.

Reference: Juniper Networks documentation on Mist Edge high availability cluster configurations.

Enable Two-Factor Authentication (2FA): Adding 2FA to administrator logins significantly enhances security by requiring a second form of verification in addition to the password, making unauthorized access more difficult.

Enable a Password Policy: Implementing a strong password policy ensures that passwords meet certain complexity and length requirements, reducing the risk of brute force attacks.

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.

Reference: Juniper Networks documentation on Mist AI AP packet capture features.

Understanding Location Determination in Mist:

Mist uses advanced methods to determine the location of clients in an indoor setting.

Possible Methods:

Triangulation: Uses angles to determine position, but not typically used by Mist.

GPS: Not feasible indoors due to signal limitations.

Probability Surface: Involves calculating the probability of a client's location, but not the primary method used.

Trilateration: Uses the distance from multiple known points to determine the exact location.

Mist's Method:

Mist primarily uses trilateration to determine the location of clients by measuring the distance from at least three access points.

Marvis Actions is a component of the Mist AI platform that provides a dashboard highlighting actionable items. This dashboard is designed to offer insights and recommendations based on the analysis performed by Marvis AI.

The focus of Marvis Actions is to present users with clear, actionable steps that can improve network performance, resolve issues, and enhance the overall user experience.

By consolidating relevant information and suggested actions, Marvis Actions helps network administrators efficiently address network challenges and optimize operations.

Reference: Juniper Networks documentation on Marvis Actions and its role within the Mist AI ecosystem.

Mist Administrative Logins: Mist administrative logins can utilize Single Sign-On (SSO), allowing administrators to log in using their corporate credentials, enhancing security and ease of access.

Guest User Access: Guest user access cannot use SSO, as SSO is intended for internal users and administrators rather than external guest users who access the network.

SSO Integration Overview

Juniper Mist Wired Assurance provides several benefits aimed at simplifying network management and enhancing performance.

B. Ability to deploy campus fabric architectures in minutes based on intent:Wired Assurance leverages automation and intent-based networking to quickly deploy and managecomplex campus fabric architectures. This feature significantly reduces the time and effort required to set up and maintain such networks.

C. 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.

These features are part of a broader suite of tools that Wired Assurance provides to streamline network operations, improve reliability, and enhance visibility into network performance.

Reference: Juniper Networks documentation on Wired Assurance features and capabilities.

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.

Reference: Juniper Networks documentation on Mist GUI and client troubleshooting procedures.

To deploy location-based services in Mist, the following components are used:

Location Sensors: These devices capture the location data from BLE tags and other devices.

BLE Tags: These are small devices that emit Bluetooth signals to be picked up by location sensors.

Location Engine: This software processes the data from the sensors and tags to determine precise locations and provide analytics.

In Mist's Service Level Expectations (SLE) framework, the Coverage SLE is responsible for reporting on RF interference.

The Coverage SLE monitors the strength and quality of the wireless signal, ensuring that clients are receiving adequate coverage throughout the network. It also identifies areas where RF interference might be degrading the signal quality.

By tracking RF interference, the Coverage SLE helps administrators diagnose and mitigate issues that could impact wireless performance and user experience.

Reference: Juniper Networks documentation on Mist SLEs and their specific metrics.

The Mist Edge device is responsible for detecting Layer 1 issues, such as bad cable actions, within the Marvis Actions framework.

Mist Edge integrates with Marvis AI to provide detailed insights into network health, including physical layer issues like faulty cables, which can impact network performance.

By identifying and alerting administrators to these problems, Mist Edge helps maintain the integrity and reliability of the network infrastructure.

Reference: Juniper Networks documentation on Mist Edge and its diagnostic capabilities.

Service Level Expectations (SLEs): In Mist AI, SLEs are metrics that define the performance standards for wireless networks in terms of capacity, coverage, and throughput.

Percentage of User Minutes: This metric represents the proportion of time users experience acceptable service levels. It provides a user-centric view of network performance, focusing on the quality of experience over time.

Identify the Problem: Suspected issue related to DHCP latency while troubleshooting a wireless client.

Understanding SLEs:

Capacity: Related to the number of clients and bandwidth.

Time to Connect: Measures the time taken for clients to connect, including DHCP latency.

Throughput: Measures the data transfer rate.

Coverage: Measures the signal strength and coverage area.

Selecting the Appropriate SLE:

Time to Connect is the relevant SLE as it includes metrics on DHCP latency, which affects the connection time.

Review the SLE:

Analyze the Time to Connect SLE to identify any latency issues with DHCP.

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.

Conclusion:

The correct answer is A.

Juniper Networks Mist Edge FAQs

When creating a label to be applied to a WLAN template in Mist AI, you should create the label at thesite 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.
