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.

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.

ï‚·The "Exceeded" status for a subscription means that the allowed usage defined within the subscription has been surpassed.

ï‚·This typically refers to exceeding limits such as the number of devices, data usage, or other metrics specified in the subscription plan.

ï‚·Exceeding these limits may require action such as upgrading the subscription plan to accommodate the additional usage.

ï‚·Reference: Juniper Networks documentation on subscription status and management.

ï‚·In Mist organizations, only users who have been granted the "invite Admin" permission have the rights to invite new administrators.

ï‚·This permission is specifically assigned to control who can add new administrators, ensuring that only authorized personnel can extend administrative access.

ï‚·Managing permissions effectively helps maintain the security and integrity of the organization's network management.

ï‚·Reference: Juniper Networks documentation on user roles and permissions within Mist organizations.

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.

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.

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

ï‚·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.

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

ï‚·Reference: Juniper Networks documentation on Mist Edge and its diagnostic capabilities.

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

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

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

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

Installer Role in Mist:

The Installer role is designed for initial site setup and configuration.

Access Duration:

By default, the Installer role has temporary access for a specific duration to ensure security and control.

Default Access Duration:

7 days: Installers typically have access to a site for 7 days, enough time to complete initial setup and configuration before access expiration.

Conclusion:

The correct answer is A.

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.
