Pass the Juniper JNCIA-MistAI JN0-252 Questions and answers with ValidTests

Machine Learning in Wireless Assurance: Mist's Wireless Assurance uses machine learning to analyze telemetry data and identify potential network issues. This approach allows for proactive identification and resolution of faults, improving overall network reliability and performance.

The Simple Network Management Protocol (SNMP) is used by Mist to monitor non-Juniper switches. SNMP is a widely adopted protocol for network management, enabling the collection and organization of information about managed devices on IP networks.

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.

AP and RADIUS Server Communication: By default, the communication between an Access Point (AP) and a RADIUS server is not encrypted. This can be configured to be encrypted, but it is not the default setting.

Wi-Fi Client and AP Communication: By default, the communication between a Wi-Fi client and an AP is encrypted, typically using WPA2 or WPA3, which ensures the data exchanged over the wireless network is secure.

RADIUS Configuration Guide

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.

Juniper Location Deployment Guide

Asset Tracking: Asset tracking is a common use case in LBS deployments, enabling organizations to locate and manage assets in real-time. This is particularly useful in environments like hospitals, warehouses, and large corporate campuses where knowing the precise location of equipment can save time and improve efficiency​(CertsHero)​.

Wayfinding: Wayfinding helps users navigate through complex environments, such as large buildings, airports, and shopping malls. By providing real-time navigation assistance, LBS enhances the user experience and improves accessibility within these spaces​(CertsHero)​.

System Platform Components in Mist UI:

Different components provide various insights and information about the network.

Component Descriptions:

Switch Insights: Provides detailed information about switch performance and status.

Events: Logs and displays events occurring in the network but does not specifically highlight missing VLANs.

Marvis Actions: AI-driven insights and recommendations that include identifying and suggesting actions for missing VLANs.

Service-Level Exceptions (SLEs): Monitor and report on performance metrics, not specifically focused on VLAN issues.

Conclusion:

The correct answer is C (Marvis Actions).

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.

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.

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.
