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

Mist APs have the capability to capture both wireless and wired packets. This feature allows for comprehensive network troubleshooting by providing visibility into both types of traffic.

When performing packet captures on Mist APs, the APs remain in service. This means they continue to operate and serve clients while the capture is ongoing, ensuring minimal disruption to network operations.

This functionality is critical for maintaining network availability and performance while conducting detailed packet analysis.

Reference: Juniper Networks documentation on Mist AI AP packet capture features.

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.

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.

Reference: Juniper Networks documentation on Mist Edge high availability cluster configurations.

Identify the Problem: Suspected issue related to DHCP latency while troubleshooting a wireless client.

Understanding SLEs:

Capacity: Related to the number of clients and bandwidth.

Time to Connect: Measures the time taken for clients to connect, including DHCP latency.

Throughput: Measures the data transfer rate.

Coverage: Measures the signal strength and coverage area.

Selecting the Appropriate SLE:

Time to Connect is the relevant SLE as it includes metrics on DHCP latency, which affects the connection time.

Review the SLE:

Analyze the Time to Connect SLE to identify any latency issues with DHCP.

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.

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

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

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

Reference: Juniper Networks documentation on subscription status and management.

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).

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.

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.
