JN0-252 Mist AI- Associate (JNCIA-MistAI) Questions and Answers

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.

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.

Types of APs and Security Threats:

Understanding different types of access points and their potential security threats.

Access Point Types:

Neighbor AP: An access point that belongs to a neighboring network and is not necessarily a security threat.

Rogue AP: An unauthorized access point connected to the wired network, posing a significant security threat.

Spoofed AP: An access point that mimics a legitimate one, but typically does not involve being connected to the network.

Honeypot AP: An access point set up to lure attackers, not necessarily a threat unless used maliciously.

Identifying the Threat:

An AP connected to your wired network but not claimed to your organization is considered a rogue AP and poses a security threat.

Conclusion:

The correct answer is B.

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.

Identify the Scenario: Five clients on the network and 20 minutes of statistics for each client.

Calculation:

User Minutes = Number of Clients × Duration of Statistics.

User Minutes = 5 clients × 20 minutes per client.

User Minutes = 100.

Conclusion:

The total user minutes in this scenario is 100.

In the Mist architecture, an organization is a higher-level entity that can contain multiple sites.

A. A site is contained within an organization:Each site operates under the umbrella of an organization, allowing centralized management and policy enforcement.

B. Multiple sites may be contained within a single organization:This structure enables organizations to manage and monitor different geographical locations or different business units within a single centralized framework.

This hierarchical structure facilitates scalable and organized network management.

Reference: Juniper Networks documentation on organizational structure and site management in Mist.

To set up a new WLAN that is Open Access and prevents connected clients from communicating with each other, you should use theConfigure Isolationfeature. 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.

Best Practices for WLAN Security

Line of Sight: For optimal accuracy and stability of location-based services, each access point (AP) should have an unobstructed line of sight to at least two other APs. This ensures robust triangulation and accurate location tracking.

Ceiling Mounting: Mounting APs on the ceiling with the LED facing the floor is recommended. This position provides the best coverage and performance for both Wi-Fi and BLE signals, essential for reliable location services.

Mist Cloud Communication Protocol: The Mist cloud platform uses HTTPS (Hypertext Transfer Protocol Secure) to communicate with connected access points. This ensures that the data sent and received is encrypted and secure, adhering to modern security standards​(Juniper Networks)​​(CertEnsure)​.

Security and Reliability: Using HTTPS provides a secure channel over which configuration changes, updates, and monitoring data can be safely transmitted between the Mist cloud and the access points. This protocol is widely accepted and trusted for secure communications over the internet.

Incorrect Options:

MQTT: While MQTT is a lightweight messaging protocol often used in IoT, it is not the protocol used by Mist cloud for AP communication.

SSH: Secure Shell (SSH) is primarily used for secure remote command-line access and not for the primary communication between Mist cloud and APs.

PPTP: Point-to-Point Tunneling Protocol (PPTP) is used for implementing VPNs and is not relevant to the communication between Mist cloud and access points.

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.

Location Engine: The location engine runs in the cloud and processes data from BLE tags and sensors to determine the location of devices within a network. It performs the necessary computations to provide accurate location tracking and analytics.

Location System: The location system, also cloud-based, integrates with the location engine to provide a complete solution for tracking and managing location data within Mist’s ecosystem. This system supports various applications such as asset tracking, wayfinding, and proximity-based services.

Mist AI Technology

For Marvis, Mist AI’s virtual network assistant, to provide a visualization of low coverage and low-capacity issues within the network, a floor plan is required. This enables Marvis to map the coverage and capacity data to specific locations within the physical space, allowing for precise identification and troubleshooting of network issues.

Marvis Actions

Understanding Marvis Queries:

Marvis is the AI-driven virtual network assistant in Mist that helps with queries and troubleshooting.

Language Used for Queries:

Natural Language: Marvis is designed to understand and respond to natural language queries, making it user-friendly.

Python, C++, SQL: These are programming and query languages not used directly for Marvis queries.

Conclusion:

The correct answer is A (Natural Language).

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.

Reference: Juniper Networks documentation on Mist AI and Junos compatibility requirements.

Wi-Fi Location-Based Services (LBS) provided by Mist require the User Engagement subscription.

This subscription includes features that enhance user interactions and engagement, such as location services, which are critical for delivering personalized and location-aware experiences.

By leveraging Wi-Fi LBS with the User Engagement subscription, organizations can offer advanced services like wayfinding, asset tracking, and location analytics.

Reference: Juniper Networks documentation on subscriptions required for Wi-Fi LBS and User Engagement services.

When a Mist subscription expires, the devices associated with that subscription continue to operate normally, ensuring there is no immediate disruption to network operations.

However, management capabilities through the Mist management GUI are restricted. This means that while the devices remain functional, you cannot make configuration changes, monitor, or manage them using the Mist management interface until the subscription is renewed.

This restriction emphasizes the importance of maintaining active subscriptions for full access to Mist’s management features.
