Juniper Mist AI, Associate JN0-252 Exam Practice Test

Answer : B

Juniper Mist Wired Assurance provides several benefits aimed at simplifying network management and enhancing performance.

B. Ability to deploy campus fabric architectures in minutes based on intent: Wired Assurance leverages automation and intent-based networking to quickly deploy and manage complex campus fabric architectures. This feature significantly reduces the time and effort required to set up and maintain such networks.

C. Support for ZTP (Zero Touch Provisioning): Wired Assurance includes ZTP capabilities, which allow for the automatic provisioning and configuration of switches as soon as they are connected to the network. This reduces the need for manual intervention and speeds up the deployment process.

These features are part of a broader suite of tools that Wired Assurance provides to streamline network operations, improve reliability, and enhance visibility into network performance.

Answer : D

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.

Answer : D

To troubleshoot a wireless client that is no longer connected to a Mist AP, you would navigate to the 'Clients' section within the Mist GUI and select 'WIFI Clients.'

This area provides detailed information about all wireless clients that have connected to the Mist APs, including their connection history, performance metrics, and any issues encountered.

By examining the data available in the WIFI Clients section, network administrators can identify the root cause of connectivity problems and take appropriate actions to resolve them.

Answer : A, B

In the Mist architecture, an organization is a higher-level entity that can contain multiple sites.

A. A site is contained within an organization: Each site operates under the umbrella of an organization, allowing centralized management and policy enforcement.

B. Multiple sites may be contained within a single organization: This structure enables organizations to manage and monitor different geographical locations or different business units within a single centralized framework.

This hierarchical structure facilitates scalable and organized network management.

Answer : A, B

AP and RADIUS Server Communication: By default, the communication between an Access Point (AP) and a RADIUS server is not encrypted. This can be configured to be encrypted, but it is not the default setting.

Wi-Fi Client and AP Communication: By default, the communication between a Wi-Fi client and an AP is encrypted, typically using WPA2 or WPA3, which ensures the data exchanged over the wireless network is secure.

Answer : B, C

Packet Capture: This feature allows for detailed inspection of traffic at the packet level. Capturing packets can help identify issues with authentication protocols, such as misconfigured settings or failures in the authentication exchange process.

Client Events: Monitoring client events provides insights into the client's authentication attempts, including successes and failures. This data helps in pinpointing where in the process the failure occurs, whether at the client, access point, or authentication server.

Answer : A

In the context of Mist management, 'brownfield' switches refer to those that are already configured and deployed in a network, while 'greenfield' switches are new and have no pre-existing configuration.

Mist supports the integration and management of both brownfield and greenfield switches within the same site. The crucial requirement is that all switches, regardless of their initial state, must be running a version of Junos that is supported by Mist.

This compatibility ensures that Mist can apply policies, configurations, and monitoring uniformly across all devices, facilitating a seamless management experience.
