JN0-252 Exam Dumps - Juniper JNCIA-MistAI Questions and Answers

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.

An HTTP POST operation performs the "create" function in web communications. This method sends data to a server to create a new resource. For example, when you submit a form on a website, the data is sent to the server using a POST request, which then creates a new entry in the database.

Web Development Basics

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.

WLAN Templates Overview: WLAN templates in Mist AI are used to standardize and manage wireless configurations across multiple locations and devices. They help in maintaining consistent wireless settings and policies throughout the network.

Deployment to the Whole Organization: WLAN templates can indeed be deployed at the organization level. This allows the configurations defined in the template to be applied across all sites and access points within the organization. This approach simplifies the management and ensures uniformity across the network​(Juniper Networks)​​(CertEnsure)​.

Deployment to a Certain Site: WLAN templates can also be applied to specific sites. This is useful for organizations with multiple sites having unique wireless requirements.By applying templates at the site level, administrators can tailor configurations to meet local needs while still maintaining control through central management​(CertEnsure)​.

Incorrect Options:

Deployed to a Switch: WLAN templates are not deployed to individual switches. They are specific to wireless configurations and thus pertain to access points and wireless settings.

Deployed to a Policy: While policies can be part of WLAN configurations, templates themselves are not deployed directly to policies. Policies are typically components within the templates.

Notification Options in Mist UI:

Mist provides several options for receiving notifications about Mist cloud status changes.

Available Notification Methods:

SNMP: Typically used for network management but not a primary method for Mist notifications.

RSS: Not commonly used for real-time notifications.

Slack: Mist can integrate with Slack to provide notifications directly to communication channels.

Email: Mist can send email notifications about cloud status changes.

Conclusion:

The correct answers are C (Slack) and D (Email).

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.

Reference: Juniper Networks documentation on Mist subscription policies and management.

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.

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.
