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).

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).

Identify the Changes: Radio Resource Management (RRM) changes and their timings.

RRM Changes:

Channel and power settings based on long-term statistics.

RF template changes to channel width.

Changes triggered by SSID scheduling.

Changes triggered by DFS events.

Timing of Changes:

Long-term RRM changes to channel and power settings are typically scheduled once a day to avoid disrupting network performance.

Conclusion:

Channel and power settings across a site based on long-term statistics and baselines are made once a day between 2:00 AM and 3:00 AM local time.

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

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.

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.

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.

Site Level: WLAN objects can be created at the site level, allowing specific configurations for different locations within an organization. This helps in customizing WLAN settings based on the unique requirements of each site.

Org Level: WLAN objects can also be created at the organization level, which provides a standardized configuration that can be applied across multiple sites. This ensures consistency in WLAN settings throughout the entire organization.

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.
