Free Practice Questions for Juniper JN0-252 Exam

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.

Supported Junos Version: For Juniper Mist Wired Assurance to function correctly, the switch must be running a supported Junos version. This ensures compatibility with Mist's cloud management and AI capabilities.

Factory-Default State or Zeroize Command: The switch must boot from a factory-default state, or you can use therequest system zeroizecommand to reset its configuration. This is essential for seamless onboarding and auto-provisioning.

Understanding Location Determination in Mist:

Mist uses advanced methods to determine the location of clients in an indoor setting.

Possible Methods:

Triangulation: Uses angles to determine position, but not typically used by Mist.

GPS: Not feasible indoors due to signal limitations.

Probability Surface: Involves calculating the probability of a client's location, but not the primary method used.

Trilateration: Uses the distance from multiple known points to determine the exact location.

Mist's Method:

Mist primarily uses trilateration to determine the location of clients by measuring the distance from at least three access points.

Wi-Fi Related SLEs in Mist UI:

SLEs (Service Level Expectations) help monitor and ensure Wi-Fi network performance.

Visible SLEs:

Capacity:

B: Capacity SLE monitors the network's ability to handle the number of connected clients and their bandwidth requirements.

Throughput:

D: Throughput SLE measures the data transfer rates, ensuring that the network meets the expected performance levels.

Other Options:

Switch Health: Relates to wired network performance, not Wi-Fi.

Application Health: Generally focuses on application performance, not specifically Wi-Fi.

Conclusion:

The correct answers are B and D.

For capacity, coverage, and throughput Service Level Expectations (SLEs) in Mist AI, throughput is measured in Mbps. This unit measures the rate at which data is successfully delivered over the wireless network, providing a clear indication of network performance and user experience. Mist AI tracks these metrics to ensure the network meets the required performance standards.
